EtherCrash

Wallet Stolen
Estimated loss
$2.50M
VERDICT —OUT OF SCOPE
Root cause is private-key / signer compromise — the on-chain contract behaved exactly as written. No pre-deployment source audit or bytecode review reaches the key-custody perimeter; this is operational-security territory (HSM/MPC hygiene, key rotation, hot-wallet isolation). Bytecode would show nothing wrong.

Forensic narrative

It is reported that EtherCrash has issued a notice on Discord in which it mentioned that the EtherCrash cold wallet was stolen and there were two large withdrawals. EtherCrash stated that it will compensate users for their property losses, but it will take some time because the losses are more serious. Attack method (per SlowMist): Wallet Stolen. Reported loss: $ 2,500,000.
