$6.34 billion Binance outflow, internal AI tools also an attack path

Binance disclosed that $6.34 billion in crypto assets was withdrawn without authorization from one of its hot wallets, following a 2026 security incident. In its post-incident report, the exchange said attackers used a compromised employee computer and internal AI tools to reach the device and credentials of a wallet developer, then gained unauthorized access to the wallet's transaction-signing service to move funds outside normal withdrawal procedures. The disclosure marks the first time Binance has identified an internal AI tool as part of an attack path, though the company said AI did not autonomously steal the assets. Binance said it will bring in independent security experts for further review.
