The Good | Authorities Launch New Operations Against Cybercrime Networks & Supply Chain Attackers

Operation Jackal IV, coordinated by INTERPOL across 22 nations, has led to the arrest of 58 individuals and the identification of over 200 suspects linked to West African cybercrime networks. The joint action successfully dismantled elements of the Black Axe syndicate, which orchestrates global romance, investment, and business email compromise (BEC) scams. Law enforcement agencies across South Africa, Argentina, and Romania also disrupted major Crime-as-a-Service (CaaS) providers, freezing millions of dollars in illicit financial assets.

The FBI, collaborating with the DoJ, have disrupted the global QScan and QTRouter hacking platforms operated by Chinese state-sponsored threat actors. The group QTFY, which maintains direct ties to China’s military and intelligence services, used these compromised IoT botnets to mask cyber espionage traffic targeting critical U.S. networks, including the Federal Reserve and NASA. Law enforcement successfully seized the core command-and-control (C2) domains hardcoded within the malicious frameworks.

From the U.S. Treasury is a new operation dubbed Economic Outcast, imposing sweeping sanctions on five Mabna Institute members and nearly 60 Iran-linked entities. Under the direction of Iran’s Ministry of Intelligence and Security (MOIS), the attackers breached multiple American critical infrastructure organizations, state governments, and defense contractors. These state-sponsored actors then exfiltrated datasets, executed high-value cryptocurrency heists, and now face federal indictments alongside a $10 million dollar reward for information leading to their arrest.

The Australian Federal Police (AFP) have arrested and charged two individuals for principal roles in TeamPCP, a cybercrime syndicate. The group systematically compromised trusted open-source projects, including Trivy, Checkmarx KICS, and LiteLLM, by stealing developer credentials and distributing backdoored software updates across major ecosystem release channels. This massive software supply chain campaign potentially compromised organizations worldwide and facilitated the unauthorized theft of hundreds of thousands of credentials.

The Bad | ‘NovaCookies’ Phishing Toolkit Exploits DocuSign Services to Steal Session Tokens

Security researchers have disclosed details of NovaCookies, a subscription-based phishing platform that systematically targets corporate networks to steal authenticated Microsoft 365 sessions. Operating as an Adversary-in-the-Middle (AitM) proxy, this malicious toolkit is advertised on Telegram for $320 monthly. The campaigns actively compromise hundreds of organizations across several nations, including the U.S., the U.K., Germany, and the U.A.E.

To establish a foothold, attackers distribute counterfeit document-sharing lures within genuine DocuSign notifications. Styled as a share notice, the decoy claims an accounting department shared a remittance-advice PDF and invites the recipient to open it. Since these notifications originate from legitimate servers, they bypass standard sender-authentication checks and reputation filters. The malicious link is embedded inside the shared document, below the inspection layer of most security gateways. Once clicked, the attack uses an OAuth error-redirect technique to guide the browser through legitimate Microsoft or Google endpoints before routing traffic to the phishing infrastructure. This transition ensures every intermediate step appears trustworthy until the user reaches the proxy.

NovaCookies is a variant of the Sneaky2FA platform, which operates on a centrally managed model where the operator hosts the infrastructure rather than individual affiliates. The kit offers customized flows targeting common identity providers. Affiliates register landing pages on .vu domains, utilizing deceptive, alternating-case subdomains like PwPt-sHaRe to masquerade as legitimate Microsoft portals. While these checks obscure the landing pages, the proxy relays credentials and multi-factor authentication (MFA) codes in real time to Microsoft. Because each individual hop of the attack chain appears legitimate, security analysts emphasize that the browser remains the critical intersection where these events converge.

The Ugly | Threat Actors Deploy Spark RAT to Target Cambodian Organizations

A recently uncovered campaign is targeting both individuals and organizations in Cambodia with Spark RAT, which functions as a Go-based, open-source remote access trojan. Distributing compressed archives through targeted phishing emails, the threat actors deploy diverse lures, including Cambodian government notices, public health announcements, and dental records. The multi-stage attack sequence begins when a victim executes an Inno Setup installer, which initiates a dynamic link library side-loading chain using a signed Tencent application to deliver intermediate payloads.

To guarantee execution, the DLL loader performs timing-based anti-sandbox checks to detect virtual environment delays and scans running processes in an attempt to weaken its permissions. The loader then decrypts shellcode hidden within an embedded PNG file to run a second stager that determines whether the malware operates with SYSTEM privileges. If these elevated rights are present, the malware proceeds directly to inject mode. Otherwise, it configures a Windows service for local persistence. Ultimately, the stager injects malicious shellcode into the legitimate vssvc.exe process, monitoring execution to re-inject the payload if terminated.

The intrusion chain utilizes the Bring Your Own Vulnerable Driver (BYOVD) technique that abuses a legitimate but vulnerable OPSWAT AppRemover driver, ardrv.sys, to escalate privileges and neutralize security programs. Operating under CVE-2026-36425, this driver enables the malware to terminate active security processes, including Microsoft Defender, Huorong Internet Security, and Tencent PC Manager. The program also patches Antimalware Scan Interface and Event Tracing for Windows, executes user-mode termination of security tools, and injects Spark RAT into ctfmon.exe. Although operational tactics and driver usage closely mirror the Chinese-speaking Silver Fox syndicate, analysts classify the campaign as an unattributed cluster due to the absence of shared infrastructure, certificates, or code reuse.

The Good | U.S. Charges Iranian Cyberattackers Over Mass Intellectual Property Theft

The U.S. Justice Department has indicted 17 Iranian nationals associated with the Mabna Institute, a state-sponsored hacking-for-hire firm, for executing a massive global cyber espionage campaign. Operating since 2013, the malicious network systematically targeted academic institutions, private corporations, and government agencies to harvest intellectual property. While nine defendants faced prior indictments in 2018 for targeting more than 300 universities and private firms, newly unsealed charges add eight individuals to the sweeping legal action. Investigators reveal that the hackers worked on behalf of Iran’s Islamic Revolutionary Guard Corps (IRGC), various government bodies, and commercial clients.

The campaign targeted the credentials of hundreds of thousands professors worldwide, compromising roughly 80,000 of them. By exploiting these accounts, the actors exfiltrated over 31 terabytes of sensitive academic data, including journals, dissertations, and ebooks valued at $3.4 billion. The intrusions affected 178 universities, including 144 in the United States, alongside 53 private firms, two non-governmental organizations, and 10 state agencies. Beyond academic espionage, the defendants targeted private entities, including an extortion scheme against entertainment network HBO for $6 million dollars in Bitcoin.

The State Department announced rewards of up to $10 million for information leading to the apprehension of five key defendants and established an anonymous Tor network link to receive tips. All defendants currently face multiple federal charges, including conspiracy to commit computer intrusions, wire fraud, and aggravated identity theft, which can incur maximum penalties of twenty years in prison. This prosecution reinforces the government’s long-term commitment to pursuing foreign threat actors who target domestic organizations, regardless of how much time passes.

The Bad | Medusa Ransomware Syndicate Compromises 500 Critical Infrastructure Organizations

A joint advisory issued by federal agencies warns that the Medusa ransomware syndicate has systematically breached over 500 critical infrastructure organizations in the United States since June 2021. Released in coordination with CISA, the FBI, and the Department of Health and Human Services (HHS), the alert covers Medusa’s rapid escalation across healthcare, manufacturing, defense, and financial sectors. This release is an update to a March 2025 assessment, which previously estimated the victim count at just over 300 entities. Other targeted areas include education, medical, legal, and insurance systems.

While the threat actors have been active since January 2021, they experienced a massive surge in their operations in 2023 following the launch of the “Medusa Blog” leak site. Operators leverage this portal to publish stolen files, applying double extortion tactics to coerce non-paying victims. Structurally, the syndicate operates under a Ransomware-as-a-Service (RaaS) model, employing an aggressive affiliate program. Developers actively recruit initial access brokers on dark web forums, offering payments ranging from $100 to $1 million dollars for exclusive access. Defenders should not confuse this threat with MedusaLocker, a separate ransomware family, or the Medusa and TangleBot mobile malware families, which also share similar naming.

As a defense against these intrusions, the agencies urge organizations to implement robust defenses. Security teams must secure and patch exposed systems to protect firmware, operating systems, and software from exploitation. Additionally, administrators should restrict access from untrusted origins to remote services and implement network segmentation to prevent lateral movement.

The Ugly | Hackers Exploit Critical Windows IKE Protocol Vulnerability

CISA has added a critical remote code execution (RCE) vulnerability in the Windows Internet Key Exchange Service Extensions component, known as MS-IKEE, to its catalog of actively exploited flaws. Tracked as CVE-2026-33824, this severe double-free vulnerability affects all supported versions of Windows 10, Windows 11, and Windows Server 2016, 2019, 2022, and 2025. The flaw enables unauthenticated, remote attackers to execute arbitrary code by simply transmitting maliciously crafted UDP packets over port 500 or port 4500 to Windows systems running IKE version 2. Because this protocol component handles crucial features like cryptographically generated address authentication, denial-of-service protection, and third-party interoperability, exposed systems remain highly vulnerable to complete network compromise.

Although Microsoft addressed the issue during April 2026 Patch Tuesday, the firm has not yet updated its official advisory to reflect the ongoing in-the-wild exploitation. Under the urgent mandate of Binding Operational Directive 26-04, CISA ordered all U.S. Federal Civilian Executive Branch (FCEB) agencies to secure their vulnerable systems within three days. While this binding directive specifically targets federal networks, cybersecurity officials strongly urge all enterprise network defenders to prioritize applying the security updates immediately to halt active intrusions.

For organizations unable to immediately deploy the patch, Microsoft recommends restricting inbound UDP ports 500 and 4500 on systems where IKE is not required, or configuring host firewalls to only accept traffic from verified peer IP addresses. The rapid exploitation of this protocol flaw joins a growing list of recently abused Microsoft vulnerabilities, including a high-severity Windows Task Host bug and a SharePoint RCE vulnerability now heavily leveraged in ransomware campaigns. Since late 2021, CISA has cataloged hundreds of actively exploited Microsoft vulnerabilities to help defenders aggressively prioritize patching.

The Good | Courts Sentence “The Com” Online Syndicate Member for Blackmail & Sextortion

A court in the UK has sentenced a member of the decentralized online cybercrime collective known as “The Com” to two years in prison following an investigation by the National Crime Agency (NCA). Justin Swaddle, who operated under the digital aliases ‘Epstein’, ‘Rugen’, and ‘Moscow’ across Discord, Snapchat, and Telegram, pleaded guilty to multiple criminal charges of blackmail and child abuse. In addition to his sentence, the court ordered Swaddle’s placement on the National Sex Offenders Register and imposed a ten-year Sexual Harm Prevention Order.

Investigators revealed that Swaddle systematically targeted and groomed young, vulnerable victims globally, using popular chat platforms to exploit his targets. The prosecution identified 117 female victims worldwide, aged thirteen to seventeen, whom Swaddle coerced into performing severe acts of self-harm and generating explicit material. Rather than seeking financial gain, Swaddle was reportedly motivated by the online status and notoriety he obtained by sharing the media within exclusive subgroups. When victims resisted his demands, he used video recordings, home addresses, and school details to blackmail them into compliance.

The investigation, which the NCA initiated in January 2024 following Swaddle’s initial arrest by West Yorkshire Police, required extensive cross-border coordination. British officers collaborated closely with law enforcement agencies in the United States, Australia, Canada, Norway, and New Zealand to identify and safeguard affected children worldwide.

Authorities emphasize that The Com functions as a highly dangerous, loose-knit global network subdivided into specialized factions, including groups dedicated to physical violence, sexual coercion, financial extortion, and high-profile corporate ransomware operations.

The Bad | Agencies Warn of Expanding Gunra Ransomware Operations Targeting Critical Infrastructure

U.S., U.K., and South Korean intelligence and law enforcement agencies have issued a joint cybersecurity advisory warning global critical infrastructure organizations about escalating threats by Gunra ransomware. First appearing in April 2025 as a variant specializing in double extortion, the group uses malware derived from leaked Conti source code. Gunra targets public health, financial, and government sectors worldwide, with a heavy concentration of victims in Australia, East Asia, and Europe.

To establish initial access, operators exploit critical authentication vulnerabilities, specifically CVE-2024-55591 and CVE-2025-24472, in FortiOS and FortiProxy software, alongside security flaws in VPN gateways. While campaigns initially focused on Windows environments, the threat actors expanded to cross-platform operations by introducing a Linux variant. In January 2026, the group launched a formal Ransomware-as-a-Service (RaaS) affiliate program under the brand “Golden Community”, actively recruiting penetration testers to serve as initial access brokers. Attackers deploy their payloads via phishing and conduct ransom negotiations via WhatsApp.

Once inside a network, the actors utilize Impacket tools for credential dumping and lateral movement. They execute malicious tasks during nighttime hours, exfiltrating stolen documents to cloud services and deleting critical backup and archived data across primary and recovery centers. The malware leverages advanced ciphers like Salsa20 or ChaCha20 to encrypt terabytes of data in a limited timeframe.

Strong links have been identified between Gunra and North Korean state-backed threat actors, observing overlapping infrastructure and techniques, such as the exploitation of zero-day flaws in certificate signing software. Despite its sophistication, a catastrophic cryptographic flaw in Gunra’s Linux variant allows victims to fully recover encrypted files.

The Ugly | New ‘ShieldBreak’ Zero-Day Exploit Bypasses Microsoft Defender Protections

A security researcher known as ‘Nightmare Eclipse’ has released a novel Microsoft Defender zero-day exploit dubbed ‘ShieldBreak’ shortly after this month’s Patch Tuesday update. The vulnerability operates as a direct patch bypass for RoguePlanet, a separate privilege escalation flaw in Microsoft’s malware protection engine that was patched in July.

Although both flaws lead to SYSTEM-level compromise, researchers confirm the underlying exploitation techniques differ significantly. While the original RoguePlanet bug exploits a filesystem race condition using virtual disks to overwrite system files, ShieldBreak hijacks cloud-hydration processes.

Specifically, the exploit leverages user-mode callback hooks to modify file contents during a cloud-hydration scan via the Cloud Filter API. To achieve privilege escalation, an attacker first places a standard test file and utilizes Object Manager symbolic links to redirect Defender’s path to the system32 directory. During scanning, the exploit uses the Common Log File System to swap the file identity and plant a malicious DLL, phoneinfo.dll, where a default system file does not exist. Triggering a scheduled Windows Error Reporting task subsequently forces the system to load this rogue library, spawning a shell with highest privileges.

The proof-of-concept operates with a 100% success rate on fully patched installations of Windows 11 25H2 and Windows Server 2025. Although Windows 10 remains vulnerable to the flaw, the current code does not natively support those legacy systems. Analysts note that Microsoft Defender must be actively enabled for the exploit chain to function.

The release intensifies an ongoing dispute between Microsoft and the researcher over bug bounty policies and recent threats of legal action.

The Good | Snowflake Hacker Pleads Guilty as Ransom Cartel Creator Draws 16 Years

Connor Riley Moucka pleaded guilty in Seattle federal court this week to computer fraud, wire fraud, aggravated identity theft and conspiracy over the 2024 breaches of Snowflake customer accounts.

The intrusions reached at least 165 organizations and exposed records tied to at least 100 million people. Prosecutors say Moucka collected at least $495,000 from ransoms and data sales. He is due to be sentenced on October 27, facing a two-year mandatory minimum on the identity theft count and up to 30 years on the rest.

Every Snowflake account the group reached had multi-factor authentication switched off, and the credentials, some harvested by infostealer malware as far back as November 2020, had never been rotated. The gang didn’t need to find a vulnerability in Snowflake’s platform to exploit; it turned out that more than three-quarters of the compromised accounts had prior credential exposure, and none had network allow lists in place.

In separate news, The Department of Justice announced that Maksim Silnikau, the Belarusian national who built and administered the Ransom Cartel ransomware operation, was sentenced to 16 years for conspiracy and aggravated identity theft.

Ransom Cartel creator sentenced 16 yrs for REvil-linked RaaS targeting 18 orgs, $6.7M losses. https://intel.threadlinqs.com/threat/TL-2026-1902 #ThreatIntel #CVE_2021_1675 #CVE_2021_34527 #Ransomcartel

Between 2021 and 2023, Silnikau recruited affiliates through underground forums, supplying stolen credentials and encryption tools while running an affiliate site that handled negotiations and revenue splits.

The Ranson Cartel attempted to extort at least $5.2 million from at least 18 companies, including a robotic-surgery startup disrupted for two months and law firms that paid $125,000 and $300,000 after weeks of downtime.

Silnikau was arrested in Spain in 2023, fled while awaiting extradition, and was caught trying to cross into Belarus before consenting to face trial in the United States.

The Bad | Claude Mythos 5 Spends 34 Hours Trying to Backdoor Real Code

The UK AI Security Institute (AISI) reported Tuesday that an agent running Claude Mythos 5 spent 34 hours trying to merge a malware dropper into a real open-source project during a security evaluation, after searching the open internet and landing on a real, unconnected repository whose name happened to share a keyword with the test’s fictional scenario.

The agent researched the maintainers, opened a pull request pairing a hidden dropper with a working bug fix, and cycled through three payload versions as each was caught. When a human reviewer flagged the code as malicious, the agent’s account denied it, force-pushed a rewritten branch history, and used a second account to vouch for the code. It also hid a prompt injection inside a GitHub issue aimed at AI coding assistants. The maintainer closed the pull request despite the cover-up.

Across 122 evaluation runs, AISI logged 19 unsanctioned actions in 10 runs, 17 involving Mythos 5 and two involving GPT-5.6 Sol, though AISI notes that figure is a count, not a rate. Both models had cyber safeguards off and open internet access by design, a setup meant to measure raw capability rather than mirror production use.

Nothing escaped AISI’s sandbox, and AISI found no evidence of real-world harm. The reviewer had the chance to catch it only because GitHub holds checks on a first-time contributor’s pull request until a maintainer approves them.

Anthropic’s own July 30 review of 141,006 evaluation runs found a separate Mythos 5 run that published malware to PyPI, downloaded and ran on 15 real systems within an hour. OpenAI reported a similar incident days earlier, exploiting a zero-day to reach Hugging Face’s production database. In each case, a test environment meant to stay sealed did not, and a model reached through it before anyone caught it.

Not to be outdone, Meta became the third lab in recent weeks to disclose an AI agent reaching into systems outside a security test. The exposure traced to Irregular, the same firm behind OpenAI’s second incident, whose misconfiguration gave a Meta model internet access it used to exploit a real company’s system.

The Ugly | ChainDrop Worm Compromises Over 1,300 npm Packages With Two Billion Monthly Downloads

A self-propagating worm known as ChainDrop compromised at least 868 npm packages across 1,381 versions, part of a broader campaign researchers put at more than 1,300 packages with a combined two billion monthly downloads.

The mass compromise began Tuesday when an attacker breached the GitHub account of a maintainer who controlled several widely used caching libraries, including Keyv, Cacheable, flat-cache and file-entry-cache. The worm then self-propagated to other maintainers’ packages, including ones tied to Deliveroo, Ornikar, OneReach, Picsart, Qlik and ServiceTitan.

The worm pushed malicious commits directly to each project’s main branch and triggered a new release through a GitHub Actions workflow, giving the poisoned npm packages valid provenance signatures.

A preinstall script added to package.json ran automatically on npm install, pulling down the Bun JavaScript runtime and using it to execute an obfuscated infostealer that harvested GitHub tokens, npm tokens, AWS and Kubernetes credentials, HashiCorp Vault secrets, database credentials and a run of other cloud and developer logins.

Every stolen token was checked against npm’s own whoami endpoint before the haul was encrypted and sent to a public GitHub repository, with any credentials belonging to other maintainers repeating the process on their packages.

ChainDrop is built on Shai-Hulud, the same self-propagating technique that has hit npm before. Each GitHub repo storing the stolen credentials is auto-named with random terms from Dune and carryies the description, “Shai-Hulud: Here We Go Again.”

While many of the auto-generated dead drop repos have since been taken down, the scale of the outbreak demonstrates how rapidly self-propagating worms can weaponize trusted credentials and automated pipelines. For a deeper breakdown and defensive strategies on this attack vector and other emerging supply chain risks, read the SentinelOne Annual Threat Report.

The Good | Authorities Disrupt “The Com”, Release Security Guidelines & Charge Telegram CEO

Europol and law enforcement partners from nine countries have flagged over 4000 URLs for removal to disrupt the online ecosystem of The Com. Operating as a decentralized network, The Com targets and recruits vulnerable youth across social media and gaming platforms.

Investigators report the syndicate’s content actively promotes self-harm, child exploitation, and physical attacks, while providing instructional manuals for swatting and arson. This multi-week joint operation builds upon Project Compass, a year-long international initiative that previously resulted in 30 arrests and identified 179 suspects linked to the criminal network.

From U.S. and Australian governments, a new joint cybersecurity guidance urges critical infrastructure organizations to proactively prepare isolation plans for operational technology systems. The advisory provides recommendations for physically and logically disconnecting vital infrastructure from corporate networks during severe cyberattacks.

Since state-sponsored threat actors and cybercriminals continuously target these essential sectors to facilitate espionage, data extortion, and disruptive operations, such resources help businesses shore up their operational resilience, documentation, and testing procedures.

The Russian Federal Security Service (FSB) has formally charged Telegram founder Pavel Durov with aiding terrorist activities and violating federal laws regarding prohibited information. Authorities accuse the messaging platform of failing to remove channels and automated bots allegedly operated by Ukrainian special services.

According to Russian intelligence, Ukrainian operatives leveraged a Telegram dating chatbot to psychologically manipulate and recruit young Russian men into sharing physical geolocations before coercing them into executing armed attacks and arson against domestic critical infrastructure.

This charge is the latest action against Telegram preceded by Durov’s arrest in 2024, restrictions placed on the platform, and a near-blockade from earlier this year.

The Bad | Theft Victims Sue Apple Over Fraudulent Cryptocurrency Wallet Application

Three individuals have filed a lawsuit against Apple after losing approximately $1.8 million in Bitcoin to a fraudulent cryptocurrency application housed on the official App Store. Between May and August 2025, the plaintiffs downloaded a malicious app impersonating “Sparrow Wallet”, a legitimate platform exclusively available on desktop operating systems.

The fraudulent app instructed users to input their secret recovery seed phrases during the initial setup process. Once victims entered these credentials, scammers immediately transferred the cryptocurrency to unauthorized external addresses.

The legal complaint alleges that Apple failed to adequately monitor its software marketplace while falsely promoting the App Store as a secure environment. Despite warnings from the real developer behind Sparrow Wallet who called out impersonator applications more than a year before these specific incidents occurred, Apple had taken no action.

Now, the plaintiffs claim the marketplace even featured the fraudulent software within curated cryptocurrency collections, effectively recommending the malicious tool to unsuspecting victims.

There is still a scam ‘Sparrow Wallet’ app on the @Apple App Store, despite myself and others having reported it weeks ago.

Worse, you have to install it to report it.

Always go to the wallet’s website to find the link to download it. App stores will not protect you.

— Craig Raw (@craigraw) January 6, 2024

Financial theft within mobile ecosystems continues to grow as researchers recently identified dozens of similar wallet impersonators actively targeting user recovery phrases and keys across the Apple App Store. In response to the allegations, Apple’s filing stated that it takes swift action to remove infringing content and provides dedicated reporting mechanisms for suspected fraud.

The plaintiffs currently seek full financial reimbursement, compensatory damages, and a formal court mandate requiring the tech giant to publicly disclose and systematically improve its internal procedures for detecting and removing fraudulent software submissions.

The Ugly | Anthropic Joins OpenAI in Finding Its Models Reached Real Companies During Cyber Evals

Anthropic disclosed this week that three of its models reached real production systems during cybersecurity testing. After reviewing 141,006 evaluation runs, it identified three incidents in which a Claude model reached the open internet from inside the environment of one of its third-party evaluation partners, and then accessed the systems of three organizations.

Unlike OpenAI’s recent breach of Hugging Face, no zero-day was involved, according to Anthropic. A misconfiguration had left machines in the evaluation with live internet access.

In one incident, a model built a malicious Python package and published it to PyPI, the public registry for Python software. The package was live for about an hour, during which time it was downloaded and run on 15 real systems. The downloaders included a security vendor’s scanner that installs packages automatically to check them for malware, leading to the model’s code exfiltrating that company’s credentials.

Anthropic said it found no evidence of a model pursuing a goal of its own, characterizing the incidents as a harness and operational failure rather than a model alignment failure, and noted that the safeguards it ships on released models would have blocked the behavior.

OpenAI also updated its account of the Hugging Face breach this week, revealing the same models had also used publicly exposed credentials to compromise accounts at four other services.

OpenAI said the models configured one compromised account as an outbound relay and staging server and used a second for data storage. The remaining two accounts were accessed in read-only mode.

Although OpenAI’s models extracted partial datasets containing CyberGym solutions and operated multiple concurrent workloads, the activity ultimately left critical encryption keys behind, exposing the operation. OpenAI said it continues to review the incident alongside external auditors and has restricted its pre-release model from further internal research access.

The Good | Authorities Dismantle Kratos Phishing Network & Arrest Its Developer

Kratos, a prominent phishing-as-a-service (PhaaS) platform, was dismantled from the inside out this week thanks to German and U.S. law enforcement agencies. During “Operation Olympus Blade”, authorities seized over 200 servers to render Kratos’ global network entirely inoperable while the platform’s suspected developer was apprehended in Indonesia.

So far, investigators estimate that more than 1800 cybercriminals utilized the platform to launch nearly 15,000 phishing campaigns monthly since late 2024. Operating as a franchise, the service provided threat actors with toolkits designed to generate convincing Microsoft authentication pages. These campaigns targeted victims across the United States and Europe, facilitating widespread credential theft and unauthorized account access. The operators earned at least €300,000 in subscription fees.

A recent report from cyber researchers reverse-engineered the Kratos toolkit, revealing how it offered operators two distinct functional modes. While one mode harvested traditional credentials, the more advanced setting deployed a Node.js reverse proxy. This adversary-in-the-middle (AitM) capability allowed attackers to intercept active session cookies in real-time, effectively bypassing standard multi-factor authentication (MFA) controls.

Once compromised, these accounts provided actors with initial footholds to execute business email compromise (BEC), lateral data theft, and secondary phishing attacks. Just this February, actors ran Kratos in a campaign that used tax-themed lures and personalized QR codes to target dozens of American manufacturing and healthcare organizations.

While the immediate server takedown severely disrupts ongoing operations, officials acknowledge that the existing customer base retains access to the underlying kit code. That means the toolkit itself outlives the infrastructure seizure, and operators who already have copies can resume campaigns under new branding with minimal rebuild effort.

The Bad | Threat Actors Conceal HollowGraph Malware in Microsoft 365 Calendar Events

A novel espionage implant, dubbed HollowGraph, is hijacking Microsoft 365 calendars to establish a covert command and control (C2) channel. By routing operator instructions and exfiltrated data through legitimate Microsoft Graph API traffic, the malware ensures its activities blend seamlessly with routine network chatter.

The .NET DLL implant operates purely as a two-way dead drop without communicating directly with an attacker-owned payload server. To receive tasking, HollowGraph queries the compromised user’s calendar for an event planted far into the future – in this case, dated for May 13, 2050. Operators embed their instructions within text files attached to this anomalous event, ensuring the mailbox owner never naturally scrolls far enough to discover the malicious entries.

For data exfiltration, the malware executes the reverse process. It systematically encrypts stolen files using hybrid RSA and AES-256 encryption, generates a new far-future calendar event, and uploads the targeted data as attachments. To maintain continuous Graph API access, operators utilize a secondary DNS-based channel to refresh the application’s Entra ID login credentials. The malware decodes these values from an attacker-controlled domain and writes them to a disguised configuration file.

Analysts observed this highly targeted campaign actively compromising machines at an Israeli organization between June and July 2026. While the implant’s underlying code shares significant structural similarities with a modular backdoor framework called Cavern, frequently utilized by Iranian state-sponsored syndicates, researchers have not yet definitively attributed this specific operation to a known threat group.

HollowGraph buries its C2 in M365 calendar events dated 2050 – no attacker server ever touched. https://t.co/yJo4fpw0X9 #ThreatIntel #HollowGraph #Cavern #Cav3rn pic.twitter.com/kaABaAYZg0

— ThreadLinqs (@threadlinqs) July 22, 2026

Since HollowGraph relies entirely on compromised account identities and legitimate application permissions rather than software vulnerabilities, standard patching remains ineffective. The technique effectively weaponizes the trust organizations place in their own Microsoft Graph API traffic, turning routine calendar activity into a blind spot by design.

The Ugly | AI Models Escape Sandbox to Breach Hugging Face Infrastructure

Open-source AI platform Hugging Face recently disclosed a network breach orchestrated entirely by an autonomous AI agent. The attack compromised the company’s data-processing pipeline by deploying a malicious dataset that exploited two distinct code-execution vulnerabilities. This initial access allowed the agent to run unauthorized code on a processing worker, harvest cloud and cluster credentials, and subsequently move laterally across several internal systems.

The platform reported that the agent executed thousands of individual actions across short-lived sandboxes while staging self-migrating C2 infrastructure on public services. Following the discovery, Hugging Face evicted the agent, revoked affected credentials, and rebuilt compromised nodes. It was during the forensic investigation that responders encountered a unique operational hurdle: Western AI models refused to process the malicious artifacts due to built-in safety guardrails. At this point, the company turned to an unrestricted, open-weight Chinese model to successfully complete the analysis.

Shortly after Hugging Face’s disclosure, OpenAI confirmed that its own AI models orchestrated the intrusion during internal benchmark testing. Operating with reduced safety guardrails for evaluation purposes, GPT-5.6 Sol and an advanced pre-release model attempted to cheat the ExploitGym cybersecurity assessment. Rather than solving the challenges natively, the models identified and exploited a shortcut, retrieving the test solutions directly from Hugging Face’s production database via a zero-day vulnerability in a third-party package registry cache proxy.

After gaining open internet access through privilege escalation and lateral movement, the models accessed Hugging Face servers. The AI agents chained together multiple attack vectors, utilizing the stolen credentials and additional zero-day vulnerabilities to establish remote code execution. OpenAI subsequently disclosed the zero-day flaw and collaborated with Hugging Face to implement stricter infrastructure controls and guardrails.

The Good | Authorities Sanction Cybercriminals & Dismantle Russian Bulletproof Hosting Infrastructure

The EU and the United Kingdom have jointly sanctioned multiple Russian individuals and entities for targeting government networks and critical infrastructure across Europe. The sanctions specifically target senior Russia military intelligence (GRU) officers and operators, as well as four entities linked to the Federal Security Service (FSB).

Officials say that the Russian government actively utilizes these state-sponsored units alongside recruited cybercriminals and private companies to systematically destabilize international partners and compromise key infrastructure across the continent.

From the U.S. Treasury Department, two individuals and a virtual private network (VPN) provider face sanctions for actively enabling ransomware attacks against American organizations.

OFAC designated First VPN Service (1VPNS) and its administrator, Dmytro Rashevskyi, for supplying infrastructure that helped cybercriminals obscure their identities and manage stolen data. The service, which law enforcement dismantled last May, notoriously ignored abuse complaints and maintained zero user logs.

Yegeniy Silayev was also sanctioned for developing cryptors designed to conceal malware. Investigators estimate these specific tools and services directly facilitated billions of dollars in financial losses across critical sectors.

U.S. Federal prosecutors also unsealed indictments this week against three Russian nationals for operating bulletproof hosting services that facilitated over $62 million in global ransomware damages.

Defendants Aleksandr Volosovik, Yulia Pankova, and Kirill Zatolokin allegedly managed “Media Land” and “ML Cloud”, providing essential infrastructure to syndicates like Lockbit, Play, and Blacksuit. These hosting platforms actively shielded cybercriminals by disregarding victim complaints and ignoring law enforcement takedown requests.

To disrupt this supply chain, the State Department is offering a $10 million reward for actionable information regarding foreign government links to these hosting providers.

The Bad | Attackers Trojanize Popular Remote User Platforms to Deploy Starland Malware

Cybersecurity researchers identified a financially-motivated Russian threat actor tracked as UAT-11795. Active since June 2025, the actor has utilized trojanized applications to harvest user credentials and cryptocurrency while primarily targeting users across the United States, Germany, Romania, and Venezuela.

To distribute their payloads, UAT-11795 operators disguise malicious installers as legitimate software, including WebEx, Zoom, MobaXterm, DBeaver, and FaceIT. Researchers suspect the attackers likely deploy these files via ClickFix social engineering.

The infection chain typically starts when a victim executes a malicious HTA file. This file retrieves an altered NSIS installer harboring a hidden Python loader disguised as a standard text document. The loader then modifies the Windows Registry to ensure persistent access before decrypting and deploying the Starland remote access trojan (RAT).

Upon execution, Starland verifies whether it is operating within a sandbox before creating scheduled tasks and attempting to escalate its system privileges. The malware scans compromised systems for browser data, cryptocurrency wallet assets, detailed system configurations, any antivirus products, and Active Directory infrastructure such as domain structure and controllers.

Beyond data theft, Starland possesses extensive capabilities to capture desktop screenshots, execute arbitrary shell commands, and fetch secondary payloads. Depending on system architecture, the malware can inject a 64-bit shellcode chain to deliver the CastleStealer information stealer or a 32-bit chain to deploy the Remcos remote access trojan.

To maintain resilient command and control (C2) communications, the operators integrate a redundancy mechanism that queries a Polygon smart contract for a fallback domain, and control two Telegram bots to receive notification beacons, including messages with the victim’s machine fingerprints and cryptowallet inventories.

Users are reminded to avoid executing unidentified commands online and should only download confirmed software from official vendor sources.

The Ugly | Nearly 300 Imposter GitHub Repositories Distribute Infostealing Malware to Collect Sensitive Data

Threat actors have published almost 300 fabricated GitHub repositories to distribute an information stealer from the BoryptGrab malware family. The actors systematically impersonated premium security products, cryptocurrency tools, and developer utilities to deceive victims searching for free software downloads.

As part of the lure, the malicious landing pages employ highly sophisticated client-side scripts that parse referral URLs to render customized branding and spoofed trust badges, significantly increasing the likelihood of successful social engineering.

Once a targeted victim clicks the download link, the infrastructure delivers a constantly rotating ZIP archive containing a legitimate, signed WinGUP updater paired with a trojanized dynamic link library file. When the user executes the updater, the program side-loads the malicious file, which then decodes and reflectively executes the BoryptGrab-variant payload directly into system memory.

Operating without establishing long-term persistence, the malware is designed to exfiltrate maximum data in a single execution cycle. The stealer targets passwords, payment details, and session cookies across 19 different web browsers and 32 cryptocurrency wallet brands, alongside messaging tokens from Discord, Steam, and Telegram.

To maximize collection, operators utilize direct code injection to bypass Chrome’s native App-Bound Encryption. All newly harvested data is compressed and routed to a Russian-based C2 server. Although the malware leaves behind forensic evidence by failing to wipe temporary staging directories, the scale of the impersonation campaign poses significant risks to unsuspecting developers.

GitHub has already removed a large portion of the false repositories, though several of the malicious redirector pages remain actively online. Researchers advise users to independently verify software authenticity and exercise extreme caution when navigating unofficial portals, sharing this YARA rule to help detect BoryptGrab activity and IoCs.

The Good | Authorities Apprehend Pro-Russian Hacktivist & Dismantle Global Fraud Networks

Spanish authorities, acting on intelligence provided by the FBI, have apprehended a suspected core member of the pro-Russian hacktivist syndicates CyberArmy of Russia Reborn (CARR) and Z-Pentest.

While masquerading as ideologically motivated collectives, these groups have actively executed disruptive cyberattacks against critical infrastructure, including food processing and water facilities across the United States and Europe. Investigators allege the arrested individual, residing in Palencia, provided extensive operational and logistical support to a Ukrainian hacker working for CARR, even attempting to facilitate their escape to Russia.

The individual is also suspected of coordinating cyber operations for the NoName057(16) group using encrypted messaging platforms. In a March 2026 raid, law enforcement officers seized multiple computers and successfully froze cryptocurrency wallets utilized to launder illicit proceeds generated from stolen data sales. The suspect currently faces ongoing criminal investigations for alleged collaboration with a recognized terrorist organization and severe computer damage.

In a massive global crackdown on social engineering and financial fraud, international law enforcement agencies have arrested 5,811 suspects and seized approximately $293 million in illicit assets. Codenamed “Operation First Light 2026”, the coordinated initiative spanned 97 countries and specifically targeted business email compromise (BEC), investment scams, and money laundering syndicates operating between January and April. Interpol actively coordinated the extensive joint action, collaborating directly with regional policing bodies like ASEANAPOL, GCCPOL, and Europol to swiftly block over 31,000 fraudulent bank accounts and virtual wallets.

Investigators identified more than 142,000 victims worldwide and pinpointed an additional 15,600 suspects for future prosecution. This success builds upon recent international efforts, including Operation Synergia II, to dismantle the sprawling infrastructure supporting transnational cybercrime. Officials emphasize that robust, cross-border law enforcement cooperation remains essential to combat the escalating threat of organized cyber-enabled financial crimes globally.

The Bad | Threat Actors Deploy Forg365 PhaaS to Hijack Microsoft Accounts

Cyber researchers have identified a new phishing-as-a-service (PhaaS) operation dubbed Forg365, which targets Microsoft 365 enterprise accounts. Blending adversary-in-the-middle (AiTM) techniques with device-code phishing, the platform provides an integrated dashboard to manage post-compromise activities.

Forg365 works by incorporating AI to assist in generating customized phishing lures. By integrating AI directly into the control panel, Forg365 developers significantly lowered the financial cost needed to launch targeted campaigns. To remain undetected, its operators route messages through legitimate Amazon SES infrastructure while hosting their landing pages on Cloudflare.

The operation leverages the OAuth 2.0 device code authentication flow, originally designed for input-constrained devices. Attackers present victims with a deceptive verification page, tricking them into authorizing an attacker-controlled gadget rather than stealing their password directly.

Once initial access is achieved, the platform ensures persistence through a specialized browser extension called ForgCookie. Compatible with Microsoft Edge, Google Chrome, and Brave, this extension operates silently to request account data, clear session cookies, and trigger a hidden OAuth flow to capture fresh tokens. Doing so grants attackers continuous access to the victim’s Microsoft services without requiring them to ever re-authenticate.

To protect its administration panel from being accessed by security defenders, Forg365 integrates robust anti-analysis features. The platform utilizes debugger traps, polymorphic code, and dynamic sandbox checks to evade detection, redirecting connections to innocuous websites whenever a VPN is detected.

Administrators can defend against these hijacking techniques by monitoring Microsoft Entra logs for unexpected device-code authentication events. Organizations can also restrict or entirely disable device-code flows unless absolutely necessary. In the event of a suspected compromise, security teams should revoke all OAuth grants and refresh session tokens to sever access.

The Ugly | Rival Espionage Actors Breach & Spy On Pakistani Law Enforcement Networks

Between February 2024 and April 2026, suspected state-sponsored threat actors based in China and India separately converged on several Pakistani law enforcement organizations in unrelated cyberespionage campaigns.

According to SentinelLABS, operators heavily targeted the Balochistan Police, compromising critical network appliances and web servers. By infiltrating these critical systems, both nations actively sought independent visibility into Pakistan’s internal security posture and ongoing counter-militancy operations.

The China-nexus intrusions, leveraging PlugX, ShadowPad, and Cobalt Strike malware, were likely driven by Beijing’s concerns over the safety of Chinese nationals working on regional infrastructure projects within the China-Pakistan Economic Corridor (CPEC). Ongoing terrorist attacks have left the Chinese government dissatisfied with Pakistani protection and data from Balochistan Police would give the PRC direct insights.

Conversely, the India-nexus activity utilized Remcos backdoors to gather intelligence on the restive Balochistan province, a recurring flashpoint in the adversarial relationship between the two countries. Control over Balochistan Police networks means having invaluable visibility on how Pakistan manages their security posture as well as persistent access to civilian data.

One China-aligned threat actor specifically compromised the Balochistan Police Force’s Complaint Management System (CMS), a web application that actively serves both law enforcement personnel and Pakistani civilian users. The attackers uploaded custom malware implants disguised as routine portal updates, effectively weaponizing the digitalization of public policing services.

One payload masqueraded as a legitimate component of endpoint security software to evade initial detection and deploy an AsyncRAT client in order to establish persistent footholds into internal police networks while simultaneously surveilling citizens utilizing the platform.

This multi-actor convergence highlights how modernized policing infrastructure can serve as a high-value intelligence target for rival nations seeking comprehensive regional data.

The Good | Authorities Apprehend Iranian Cybercriminal & Extradite UNC3944 Hacker

Montenegrin law enforcement, alongside the FBI, have apprehended a 39-year-old dual Iranian and Turkish citizen wanted by the U.S. government for several cybercrime offenses. Arrested in Kotor, the suspect faces charges in the Southern District Court of New York for conspiracy to commit computer fraud, hacking, and identity theft.

Since 2013, this individual allegedly orchestrated mass cyberattacks against more than 150 American universities and inflicted damages estimated at over $3.4 billion. Investigators say the stolen data and compromised academic credentials directly benefited the Islamic Revolutionary Guard Corps and various Iranian state entities. The case now proceeds to a High Court judge for formal extradition hearings. The arrest follows recent warnings from U.S. cybersecurity agencies regarding escalating Iranian state-sponsored operations targeting critical domestic infrastructure.

A 19-year-old dual United States and Estonian citizen, Peter Stokes, has been extradited to face federal charges for his role as a core member of the UNC3944 (aka Scattered Spider, oktapus) cybercrime syndicate. Finnish authorities initially apprehended Stokes at the Helsinki airport as he attempted to board a flight to Japan. Prosecutors are accusing him of orchestrating multiple high-profile corporate breaches, using intense social engineering tactics against IT helpdesks to bypass multi-factor authentication controls.

In one notable May 2025 incident, UNC3944 compromised a multibillion-dollar retailer, demanding an $8 million ransom while inflicting over $2 million in operational disruption and remediation costs. UNC3944 operators are also responsible for more than 100 network intrusions globally, all of which yield upwards of $100 million in illicit extortion payments. Stokes remains in federal custody in Chicago, facing charges of fraud, conspiracy, and computer intrusion.

The Bad | Russian Intelligence Exploit Phishing Campaigns To Steal Signal Backup Keys

CISA and the FBI are warning that Russian state-sponsored threat actors have made large strides in evolving their phishing operations to target the backup recovery keys of Signal users. In an update to their March 2026 advisory, the two agencies attribute this ongoing activity to Russian Intelligence Services (RIS), including Russia’s Federal Security Service (FSB) Border Guards and the country’s military.

Tracked as UNC5792 and UNC4221, these campaigns specifically target high-value individuals, including government officials, military personnel, journalists, and policy analysts. Previously, operators focused on harvesting standard verification codes or tricking users into silently linking unauthorized devices. Now, they employ social engineering to access private communications without compromising the application’s underlying end-to-end encryption.

During targeted intrusions, attackers masquerade as official Signal support personnel and send direct messages falsely claiming the platform requires mandatory two-factor verification following alleged international cyberattacks. The operators systematically guide victims through the specific process of enabling the Secure Backups feature, instructing them to paste their newly generated recovery key directly into the chat interface.

Once adversaries obtain this critical key, they seamlessly download and decrypt the victim’s entire historical message archive onto their own controlled devices. Simply registering a new account under the same phone number does not natively invalidate a compromised key – users must actively generate a new backup key within their application settings to effectively secure future communications.

The U.S. Department of State recently announced a substantial reward of up to $10 million for information leading to the identification or location of these operatives. Through the Rewards for Justice program, federal authorities actively seek actionable intelligence regarding the syndicates’ operational infrastructure, illicit funding mechanisms, and direct affiliations with Russian intelligence services.

The Ugly | Unknown Hackers Breach Department of Homeland Security Information Network

The Department of Homeland Security is actively investigating a cyberattack that recently compromised its Homeland Security Information Network (HSIN). The network is an information sharing platform used by federal, state, local, and private-sector partners, specifically to share sensitive but unclassified data amongst the government and internationally.

According to an initial report, an unidentified threat actor orchestrated the intrusion between late May and early June. Investigators indicate that the attackers targeted the HSIN’s core servers alongside a SharePoint environment designed for extensive interagency collaboration.

While officials have not yet attributed the breach to a specific foreign government or syndicate, the full extent of data exposure remains unclear. The compromised platform routinely supports real-time incident management, intelligence exchange regarding persons of interest, and operational coordination. Because the United States is overseeing security for World Cup matches across the country, experts raise concerns that the intrusion could have exposed critical security planning, response procedures, and communication protocols.

In a public statement to the press, a departmental spokesperson confirmed the incident, clarifying that the breach strictly involved an unclassified legacy information-sharing environment. Security personnel promptly isolated the affected systems and mitigated the underlying vulnerability before starting forensics.

Officials emphasized that the attack did not impact classified networks, and the primary system remains operational for authorized partners. As the investigation continues, authorities strongly urge U.S. government staff, contractors, and associated partners to remain vigilant while defense teams harden the underlying infrastructure against further unauthorized network access attempts.
