Researchers at Microsoft are tracking a social engineering campaign that uses passkey-themed lures to trick users into granting persistent access to their accounts and online work environments.

Threat actors are using phishing emails with blank SMTP sender fields to bypass Microsoft 365 security filters, according to researchers at ReliaQuest.

Microsoft 365 Exchange Online uses a feature called “RejectDirectSend” to block unauthenticated Direct Send emails from an organization’s trusted domain. If an attacker omits the domain field from these emails, however, RejectDirectSend will no longer block the messages. Attackers can therefore exploit this technique to impersonate internal users.

Phishing operators are increasingly shifting away from malware-laden attachments and toward trusted delivery services, authenticated domains, and multi-stage URL cloaking designed to defeat conventional email inspection. The continuously running VBSpam comparative test evaluated ten public full email-security products and one open-source solution against wanted, unwanted, and malicious mail streams. The assessment was conducted under the […]

The UK government has started implementing passkey authentication for GOV. UK One Login,UK One Login, providing over 23 million users with a faster and more secure way to access public services. This initiative aims to reduce reliance on passwords and SMS-based verification codes, which are common targets for fraud and credential theft. UK Enables Passkey […]

Researchers at Gen Digital are tracking a sophisticated social engineering campaign that’s using phony NDA documents to trick employees into moving the conversation to WhatsApp and personal email accounts. The attackers targeted an employee at Gen itself, but the employee recognized that it was a scam and played along to see what the attackers would do.

Threat actors are increasingly leveraging AI hallucinations to plant phishing links and other malicious content in AI output, IEEE Spectrum reports. Large language models (LLMs) sometimes fabricate information, including web domains, when answering users’ questions. Attackers are registering these hallucinated web domains to host phishing pages.

The U.S. Federal Bureau of Investigation (FBI) has issued an advisory warning of a wave of OAuth consent phishing attacks targeting “prominent victims, their family members, and personal acquaintances.”

OAuth phishing is an increasingly popular social engineering tactic that tricks users into granting access to their accounts without handing over their passwords.

A recent survey from Experian found that 60% of companies report fraud losses that are “somewhat or significantly higher” than in previous years, with a majority of respondents citing AI-generated phishing attacks as their top AI-related fraud concern.

Researchers at INKY observed a major phishing campaign that used SVG (Scalable Vector Graphics) image files to deliver malicious JavaScript. While abuse of SVG files isn’t new, INKY says their use in phishing campaigns has exploded over the past year.

A phishing campaign that moves the credential-harvesting page out of attacker-controlled web infrastructure and into the victim’s browser. Unlike ordinary phishing kits, which host cloned login portals on domains that can eventually be detected and disrupted, this campaign delivers malicious content assembled only after a user follows the attack chain. A blob URL is a […]

Researchers at ZeroBEC are tracking a phishing platform called “Greatness” that’s been significantly upgraded since it surfaced in 2023.

A large-scale phishing operation is abusing trusted Google services as a multi-stage redirect network to bypass email security controls, deliver highly personalized credential-harvesting pages, and, in some cases, install ScreenConnect remote-access software. The campaign’s central advantage is that it presents trusted Google-owned domains at nearly every point a gateway, proxy, or analyst is likely to […]

Microsoft is developing a new security feature for Teams messaging that will obscure QR codes sent by external users. This measure aims to help organizations reduce phishing and fraud risks associated with malicious QR code campaigns. Listed under Microsoft 365 Roadmap ID 570439, this feature is currently in development and is scheduled for rollout in […]

QR code phishing, widely known as “quishing,” has reached record levels as threat actors increasingly conceal malicious URLs within scannable images rather than placing clickable links directly in emails. The shift is helping attackers bypass traditional secure email gateways and move victims from managed corporate devices to less-protected smartphones. The company recorded an average of […]

QR-code phishing, commonly known as quishing, is evolving beyond image-based payloads. Threat actors are now rendering scannable QR codes directly from HTML tables or text within email bodies, leaving no image attachment, embedded bitmap, or <img> element for traditional email scanners to inspect. The technique targets a structural blind spot in Secure Email Gateways (SEGs). […]

Researchers at Zimperium are tracking widespread phishing campaigns that use Browser-in-the-Browser (BitB) attacks to trick users into handing over their enterprise credentials. The attackers impersonate real HR employees at major companies and target job seekers with extremely realistic interview processes.

A new phishing kit is using generative AI to fully automate voice phishing (vishing) attacks, according to researchers at Group-IB.

The phishing platform, called “Balonx,” includes a module dubbed “CallFlow” that the researchers say “represents a fundamental evolution” in the phishing-as-a-service market. This module uses four commercial AI services to conduct the attacks: OpenAI’s GPT-4o-mini, ElevenLabs’s AI voice generator, OpenAI Voice, and OpenAI Whisper.

When an organization has a security breach, it can cause significant financial, reputational and logistical damage. But in healthcare, where patient lives are on the line, the consequences can be much more catastrophic.

KnowBe4’s latest whitepaper on healthcare cybersecurity, “Hacking the Healers: How the Digital Workforce Became Cybersecurity's Frontline,” examines how decentralized clinical operations, remote staff and autonomous AI agents have dissolved traditional network perimeters, leaving healthcare organizations and patient safety vulnerable to targeted cyberattacks.
