Summary

Market maker Wintermute lost $160M from its DeFi operations after a private key generated by Profanity vanity address tool was compromised.

How It Was Compromised — DeFi via Private Key Compromise

DeFiPrivate Key Compromise

Wintermute's DeFi hot wallet used an Ethereum address generated by the Profanity vanity address tool, which had a known vulnerability allowing private key recovery through brute force. Despite a public warning about Profanity addresses weeks earlier, the key was not rotated in time.

Fund Flow & Laundering Analysis

Stolen funds remain largely in the attacker's wallet. Small amounts moved through DeFi protocols. CEO Evgeny Gaevoy suggested the attacker may be a white hat, posting an on-chain message. Funds never returned despite negotiation attempts. Still considered outstanding.
