Binance says fake job interviews and an internal AI tool enabled $6.3 billion theft

Binance said Tuesday that the Oct. 29, 2026, theft of about $6.3 billion in crypto was a months-long campaign that used a tampered developer-tool install, fake job interviews, undetected malware and an internal AI system, according to the exchange’s incident report as described by The Verge, The Hacker News and BleepingComputer1,3,4.
The company said a wallet DevOps engineer in June downloaded a trojanized Homebrew installer while seeking a popular AI coding tool via a search engine; Binance said it detected that activity, replaced the device and rotated credentials, but that the engineer’s role and colleagues on wallet infrastructure were exposed1,3,6.
In September, Binance said, a second engineer was contacted on a job platform by someone posing as a project director, completed video interviews, and downloaded a coding assignment that installed malware replacing a legitimate pyenv component, which endpoint tools did not catch3,4.
By Oct. 20, the report said, attackers used the second engineer’s computer and an internal AI tool to reach additional wallet staff and a container deployment token, then on Oct. 29 logged into a third engineer’s computer, deployed a container and triggered a malicious script against a wallet signing service1,3,4.
BleepingComputer said attackers also used Ethereum’s EIP-7702 mechanism so transfers could continue after withdrawals were suspended4. The Verge cited Binance saying multi-party computation wallets had no single key that could immediately revoke those authorizations1.
The FBI has attributed the theft to a North Korean unit known as TraderTraitor, outlets reported; co-CEO Richard Teng told CNBC he was not himself making that attribution while noting the FBI’s finding1,6.
Teng told CNBC attackers “spent months building their way in,” rejecting a single-laptop failure narrative, and said about 98% of $6.34 billion in affected assets had been replenished6. Binance said about $2.85 billion had been frozen or intercepted and that independent reviewers were being brought in1,4,6.
The Verge said Binance’s account still leaves unclear why the internal AI tool could be used to expand access1.
