Hackers Drain $320 Million From Liquid Network, Then Return Most of It

Hackers exploited an Elements bug to drain about 4,000 BTC (~$320M) from Liquid Network's federation wallet, then returned 3,400 BTC after Blockstream patched.

An attacker drained roughly 4,000 of 4,200 BTC (~$320M) from Bitcoin's Liquid Network federation wallet on September 6 by exploiting a bug in Elements, the open-source code powering the sidechain, which allowed unbacked L-BTC tokens that were redeemed for real Bitcoin through SideSwap's authorized peg-out mechanism. The self-described white-hat attackers negotiated publicly via OP_RETURN on-chain messages, demanding the bridge nodes be patched before returning 3,400 BTC (~$262.6M) and keeping about 598 BTC (~$47M). Blockstream confirmed the affected bridge nodes were patched; the network remains paused while federation members complete security work, and experts debate whether the act legally constitutes extortion.

Hackers Return $263 Million Stolen From Liquid Network

Hackers drain roughly 4,000 BTC (~$320M) from Liquid Network federation wallet, then return 3,400 BTC with ~598 BTC still outstanding.

Attackers withdrew about 4,000 Bitcoin (roughly $320 million) from the Liquid Network federation wallet, which held approximately 4,200 BTC, via the SideSwap Peg-out Authorization Key without that key being compromised. Blockstream disabled nodes and suspended transactions after disclosing the heist on Sunday. Alleged white-hat hackers returned 3,400 BTC (~$262.6M) on Monday, demanding the underlying bug be patched before releasing the remaining ~598 BTC (~$47M). The network remains paused while fixes and a safe restart are prepared.

Hackers drain $320M in Bitcoin from Liquid Network, claim they're the good guys

Attackers withdrew about 4,000 BTC (~$320M) from Liquid Network's federation wallet via a SideSwap peg-out, claiming whitehat status.

Hackers drained roughly $320 million in Bitcoin — about 4,000 BTC, 95% of holdings — from the federation wallet backing Blockstream's Liquid Network sidechain. The withdrawal occurred through SideSwap using its Peg-out Authorization Key (PAK), yet no PAK appears to have been compromised, and the exact mechanism remains under investigation. The actors embedded an on-chain message identifying themselves as whitehats, asked Blockstream to patch federation nodes first, and promised to return most of the funds after fixes are confirmed. Liquid disabled its bridge nodes and asked exchanges to suspend L-BTC deposits and withdrawals; other Liquid assets and the Bitcoin network were unaffected.

Liquid Hackers Return 3,400 Bitcoin Taken via Elements Bug, Still Holding $47M in BTC

Hackers exploited an Elements bug to take ~4,000 BTC from Liquid Network, returned 3,400 BTC (~$265M), and still hold ~598.5 BTC (~$47M).

Attackers exploited a bug in Elements, the software behind Blockstream's Liquid Network Bitcoin sidechain, to create L-BTC and withdraw roughly 4,000 BTC (about $320 million) via SideSwap's Peg-out Authorization Key, roughly 95% of Liquid's reported reserves. They returned 3,400 BTC (about $265 million at ~$78,000 per BTC) to the federation address on September 7, keeping about 598.5 BTC (roughly $47 million). The group called itself white hats, demanded node patches before returning funds, and negotiated via on-chain and PGP-encrypted messages; Ledger CTO Charles Guillemet characterized the arrangement as extortion. Blockstream says the peg-out key and other keys were not compromised, updated software is deployed, and the network remains paused pending a coordinated restart.

Risky Bulletin: BEC campaign steals €35 million from French notaries

Hackers stole over €35 million from 500+ French notary offices in a four-year BEC campaign; ANSSI spent two years helping evict the attackers.

A business email compromise campaign breached more than 500 French notary offices — about 7% of all French notaries per the Conseil Supérieur du Notariat — over four years, stealing more than €35 million by phishing initial access and silently modifying wire transfer details. France's cybersecurity agency ANSSI worked for two years behind the scenes to help notaries remove the persistent attackers, who had deep access; officials also feared hackers could issue fake notarized acts such as marriage certificates or forged real estate deals. No forged documents have been found so far, but notaries have added two-factor authentication and in-person requirements for banking details, and banks added extra checks in 2024. The newsletter also notes other incidents, including a $320 million Bitcoin extraction from Blockstream's Liquid Network and a JetBrains Cadence breach via TeamCity servers.

‘White hat’ hackers take $47 million bounty after $320 million crypto theft

Hackers withdrew $320 million in bitcoin from Liquid Network, negotiated on-chain, returned $266.5 million and kept a $47 million reward.

Purported white-hat hackers withdrew 4,000 BTC (about $320 million) from Liquid Network's own wallet, one of the largest cryptocurrency thefts of 2026. Over roughly 12 hours of public on-chain negotiation with operator Blockstream, the hackers returned $266.5 million in bitcoin and kept 598.5 BTC (about $47 million), claiming it as a reward for uncovering a bug. Blockstream deployed updated software and paused deposits and withdrawals while experts traced the flaw to the Elements sidechain framework. April thefts of $290 million from Kelp and $280 million from Drift, attributed to North Korean hackers, were previously 2026's largest.

A hacker stole $340M in a crypto heist, then returned most of it

A hacker exploited a bug to steal about 4,000 BTC (~$340M) from Blockstream's Liquid Network, then returned roughly 3,400 BTC after the bug was fixed.

A hacker exploited a bug to withdraw roughly 4,000 bitcoins worth about $340 million from Liquid Network, a settlement service launched in 2018 by crypto firm Blockstream and used by several cryptocurrency exchanges. Liquid Network paused operations, and the hacker, described as a white hat, offered to return the funds once the bug was fixed. Former Blockstream executive Samson Mow said the bug was fixed and about 3,400 BTC (~$293M) returned, leaving roughly 600 BTC (~$47M) under the hacker's control pending further security improvements. Rekt's leaderboard ranks the heist among the largest cryptocurrency thefts to date.

America's Driver's License Breach Is a National Security Disaster

Dark web service Nexus sells 153 million US/Canadian driver's licenses linked to a breach of identity verifier IDScan.

Krebs on Security revealed a dark web service, Nexus, selling access to 153 million driver's licenses and 3 million travel documents from US and Canadian citizens, roughly 63 percent of all US licenses. Circumstantial evidence links the data to identity verification firm IDScan, which confirmed it is investigating a breach, and the FBI is probing the incident. Licenses belonging to senior US officials, including Pete Hegseth, an FBI assistant director, and Krebs's own contacts were verified as genuine. The exfiltration appears ongoing, with the database growing by nearly 400,000 licenses in a single day, and the data carries significant national security value for foreign intelligence services.

Srsly Risky Biz: America's Drivers Licence Breach is a National Security Disaster

Dark web service Nexus sold 153 million US and Canadian driver's licenses, linked to identity verification firm IDScan under FBI investigation.

Krebs On Security reported that a dark web service called Nexus sold access to 153 million US and Canadian driver's licenses, claiming over a year of continuous exfiltration from a major identity verification company, with roughly 400,000 new licences added in a single day. Krebs verified the data as genuine and linked the incident via circumstantial evidence to identity verification firm IDScan, whose licences of senior US officials including Secretary of War Pete Hegseth appeared in the database; the FBI is investigating and IDScan has confirmed a breach inquiry. The article argues the data has national security implications, citing how Chinese APT espionage (Anthem, Equifax, Marriott, OPM) and Bellingcat investigations exploited leaked databases. Class action suits are being prepared, and the piece calls for stricter oversight of identity verification firms.

From Megawatts to Tokens: How NVIDIA Maximizes AI Factory Production

NVIDIA detailed DSX power-management results: Lambda gained 24% token throughput at fixed power, and an AI factory auto-shed 1MW via Emerald AI's grid program.

NVIDIA says Lambda's first validation of DSX MaxLPS on HGX B200 servers ran 19 nodes within a 16-node power budget, lifting cluster token throughput 24% (roughly 4M to 5M tokens/second) and improving performance per watt by 23%. NVIDIA projects DSX MaxLPS can enable up to 40% more GPU capacity for Vera Rubin NVL72 factories within the same megawatt budget. Emerald AI's Conductor platform, running at NVIDIA's Eos factory with Silicon Valley Power, responded to over 200 utility demand signals, automatically dropping power from 4MW to 3MW without interrupting priority workloads. The first dedicated DSX Flex commercial deployment is planned at a 96-megawatt Manassas, Virginia facility.
