2/ It all started when @officer_cia shared @spreekaway's tweet in the ETHSecurity Telegram channel. Although I had no idea what was going on at the time, just the sheer volume of assets leaving the bridge was clearly a bad sign pic.twitter.com/klHNfthVvj

1/ Nomad’s bridge got owned in a similar manner to Qubit’s QBridge. An insecure configuration of the bridge caused a specific path to allow any transaction sent. The error is inside the Replica’s “process” function.
