What happened

On February 21, 2025, Lazarus Group phished Bybit's DevOps engineer and spoofed the Safe UI to trick signers into blind-signing a masked transaction that deployed a rogue hot-wallet policy. This drained approximately $1.4-1.5 billion in ETH and assets.

FBI reports the stolen assets were being converted and laundered across thousands of addresses. DefiLlama's returned figure for this incident reflects client losses Bybit covered, not funds taken back from the attacker.
