‘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.

Revolut Exposed KYC Data After Fraudulent Government Email Passed Security Checks
Revolut handed over KYC documents, selfies, and Bitcoin transaction histories to attackers after a fraudulent email from a genuine government domain passed authentication checks.
Revolut confirmed on September 12, 2026 that it disclosed sensitive customer KYC data to an unauthorized third party after a fraudulent information request was sent from an email account operating inside a real government agency's domain, carrying valid domain authentication credentials. The exposed data included identity documents (passports, driver's licenses), verification selfies, birth dates, contact details, IBANs, account statements, and full transaction histories including Bitcoin. Revolut discovered the fraud only after independently verifying with the agency, blocked the sender, and notified law enforcement and financial regulators, but did not disclose the number of affected customers or the agency involved. Researcher ZachXBT assessed the operation was targeted at high-net-worth users, useful for fraud, impersonation, or extortion.
