Blockstream Tells Hackers To Return Remaining Bitcoin Stolen in Liquid Theft
Bitcoin infrastructure firm Blockstream has refused to negotiate further with hackers who last week stole 4,000 bitcoins from its Liquid network.
Writing on X Friday, Blockstream said that the hackers still had time to return the funds before the company would work with law enforcement.
White-hat hackers on Sunday withdrew about $320 million from the federation wallet that backs Liquid, a sidechain by Blockstream. After negotiating with Blockstream, they returned most of the funds but kept 598.5 coins worth over $46 million — demanding it as ransom.
“Blockstream will not pay a ransom for the return of stolen funds,” the post read. “Taking assets without authorization and withholding their return is a crime, not responsible disclosure. It is not white-hat activity. It is theft.”
To those responsible for the theft of bitcoin from the Liquid Network:
— Blockstream (@Blockstream) September 11, 2026
Blockstream will not pay a ransom for the return of stolen funds. Taking assets without authorization and withholding their return is a crime, not responsible disclosure. It is not white-hat activity. It is…
It added: “We will work with law enforcement, exchanges, service providers, forensic specialists, and other relevant parties to trace and recover the assets and identify those responsible.”
“We will not pay for the return of stolen property. We will not abandon our users. The Bitcoin community will not stop pursuing the funds.”
Liquid, or L-BTC, is a layer-2 created by Blockstream that allows users to fast move assets backed 1:1 with bitcoin. One of the assets, LBTC, is a token backed by bitcoin that allows for quick settlement — a bit like the Lightning Network.
Hackers were able to get the funds by exploiting an inflation bug on the Liquid sidechain to create over 4,000 LBTC that did not exist before and cash them out for real, on-chain bitcoins.
The hackers then had an exchange with Blockstream via messages written into Bitcoin blocks.
In one message, the white hats wrote: “Please fix the bug first. The chain is under risk at latest commit right now. Make sure every node is patched. Then we will transfer the money back safely after confirming the fix.”
In the latest message, the hackers slammed Blocksteam as “delusional, greedy, and arrogant,” and threatened to reveal all of Blockstream’s encrypted messages in the exchange unless the company allowed thieves to keep 10% of the bitcoins.
“You SHALL pay 10% using your own money as bug bounty or you will cause all your holders a 15% loss for your irresponsibility and stinginess,” the message read.
The Bitcoin community is still reeling after hackers in July were able to steal over 1,800 bitcoins worth close to $140 million from Coldcard wallet holders.
Users of the popular hardware wallet, created by Coinkite, were targeted because the product’s manufacturer did not use a true random number generator, allowing hackers to essentially guess investor seedphrases.

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 roster of top Seattle business leaders and regional CEOs is demanding urgent action from City Hall on public safety, calling on Mayor Katie Wilson and the City Council to roll out a concrete 100-day action plan backed by measurable goals and transparent progress tracking.
In a letter sent Thursday, executives from major area employers — including Microsoft, Starbucks, Costco, F5, Alaska Airlines, Zillow, and others — urged city leaders to protect and expand public safety funding amid growing skepticism that the city currently has an effective strategy to address crime and homelessness.
The push centers on findings from an August joint public-opinion poll of registered Seattle voters, which revealed that while every proposed safety measure drew at least 75% support across all demographics, only 34% of respondents expressed confidence in the city’s current strategy.
Pointing to severe staffing shortages — noting Seattle has just 1.31 sworn officers per 1,000 residents, far below peer cities like Denver, San Francisco, and Boston — the signatories argued that budget decisions must directly align with measurable safety outcomes.
The effort was spearheaded by major regional business leadership organizations, including the Seattle Metropolitan Chamber of Commerce, Challenge Seattle, and the Washington Roundtable. Their leaders — Joe Nguyễn, former Gov. Chris Gregoire, and Rachel Smith — jointly signed the appeal alongside dozens of local chief executives spanning technology, retail, healthcare, and sports franchises.
“Voters are asking for action, on a timeline, with results they can measure,” the coalition wrote in the letter, emphasizing that their recommendations reflect a broad consensus across the city. “This is not a narrow or partisan agenda, it is a shared baseline that Seattle residents and the business community are asking their elected leaders to deliver both now and as a sustained priority.”
The letter outlines a series of immediate and short-term actions the group is asking City Hall to enact, backed by overwhelming support in their poll:

CCTV surveillance: Activate CCTV cameras in Pioneer Square, the Stadium District, and other high-event areas to deter crime and assist law enforcement.
Foot and bike patrols: Establish regular police patrols on foot and bicycle in areas facing persistent public safety problems, specifically citing Little Saigon (90% poll support).
911 response accountability: Recommit to a standard 7-minute priority 911 response time, backed by transparent reporting when targets are missed (90% support). The letter noted data from Nordstrom showing only 29% of 911 calls from its flagship downtown store yielded a police response, compared to 100% at its Bellevue and Southcenter locations.
Drug treatment and diversion: Direct CARE Department specialists to offer treatment and shelter first, but require law enforcement to arrest and prosecute repeat offenders who repeatedly refuse help (82% support).
Open-air drug markets: Require SPD and the City Attorney to establish a clear, prioritized pathway for shutting down open-air drug markets (81% support).
Encampment bans and timelines: Institute a policy banning encampments within 250 feet of parks, playgrounds, or schools, and mandate that the city clear encampments in those zones within 72 hours (79% support).
Among those who signed the letter: Brad Smith, Vice Chair & President of Microsoft; Jeremy Wacksman, CEO of Zillow; François Locoh-Donou, CEO of F5; Matt McIlwain, Managing Director at Madrona Venture Group; Julie Sandler, Co-founder & Venture Partner at PSL Ventures; Matt Oppenheimer, Chairman of Remitly; Erik Nordstrom, CEO & Co-President of Nordstrom; Brian Niccol, Chairman & CEO of Starbucks; Ron Vachris, CEO & President of Costco; Ben Minicucci, CEO & President of Alaska Air Group; Mike Sievert, Vice Chairman of T-Mobile; and Ada Healey, Chief Real Estate Officer at Vulcan Real Estate.
The business community’s coordinated push arrives during a pivotal moment for public safety policy in City Hall, where political tensions over policing and crime response have flared in recent weeks.
While overall violent crime and homicides in Seattle dropped during the first half of 2026 compared to last year, high-profile violent incidents continue to fuel public and commercial anxiety. Downtown, Belltown, and high-foot-traffic corridors have experienced recent spikes in gun violence and fatal altercations — including multiple homicides in Belltown and Westlake Park in early September alone.
At the same time, the Seattle Police Department continues to grapple with acute staffing shortages following years of officer departures exceeding hiring goals. The persistent deficit has left response times stretched thin, prompting deep frustration from major employers and pushing retail hubs to demand a more visible police presence.
Policy friction between the Council and Wilson’s administration has also intensified. Debate has centered on the rollout of public surveillance technologies — where the mayor’s office recently paused CCTV camera expansions pending a data privacy audit — as well as ongoing friction surrounding the leadership of the police department.
Responding to the letter, Wilson told GeekWire that her administration shares the business community’s commitment to public safety, noting that “many of the specific requests they made are well underway.”
Wilson highlighted expanded foot and bicycle patrols in neighborhoods like Little Saigon and Belltown, 3,500 police officer applications currently in the queue, and an upcoming gun violence reduction strategy set to roll out next week. While noting that SPD data shows homicides and shootings at 10-year lows, Wilson acknowledged public impatience.
“We have far too much crime and public disorder and people have a right to be frustrated,” she said. “I, like everyone in Seattle, want to see that progress happen faster and steadier.”
The safety campaign comes on the heels of a 127-page independent economic study commissioned by the city, which warned that while Seattle boasts an “almost peerless” tech workforce and key AI assets, its economy is in a fragile position due to heavy corporate concentration and tax policies that penalize senior hiring.
The study noted that Seattle’s tax base remains vulnerable if major employers opt to relocate or grow outside the city limits, reinforcing the business coalition’s argument that public safety is closely tied to the city’s long-term economic stability.

Ringleader of $245M Crypto Theft Pleads Guilty
The man behind one of the biggest bitcoin thefts in history this week pleaded guilty.
Malone Lam, 22, a Miami resident from Singapore, on Tuesday admitted his role as ringleader of the international crime group which stole 4,100 bitcoins — worth over $230 million at the time — to fund a life of luxury.
The U.S. Department of Justice said that from October 2023 and through at least May 2025, Lam and others hacked databases to steal crypto users’ information and con them into providing user logins and private keys. Bitcoin and other cryptocurrencies worth $245 million were taken in the theft.
On one occasion, a co-defendant broke into a residence in New Mexico and stole a hardware wallet while Lam monitored the victim’s movements by hacking their iCloud account.
“This defendant led an international network that preyed on victims through deception, invaded their privacy, and stole hundreds of millions of dollars in cryptocurrency,” U.S. Attorney Jeanine Ferris Pirro said in a statement.
“If you build a cybercrime empire, we will find you, dismantle your operation, and hold you accountable,” Attorney Pirro added.
The DOJ said: “The Racketeer Influenced and Corrupt Organizations Act conspiracy used social engineering and occasional home break-ins to obtain information that allowed the conspirators to drain their victims’ cryptocurrency wallets.”
The crimes started after a group of online gamers became friends before working together to commit the cybercrimes, the indictment read.
Lam and co-defendants laundered the stolen bitcoin and spent it on bottle service parties, private jet rentals, security guards, luxury handbags and watches, and properties in Los Angeles, the Hamptons, and Miami.
The defendants would spend up to $500,000 a night on parties and give away designer handbags worth tens of thousands of dollars, Tuesday’s announcement read.
Lam was arrested in 2024 at his rental home in Miami.
