Bybit hack (February 2025)
North Korean hackers stole $1.5 billion from the Bybit exchange by compromising a developer's machine at wallet provider Safe{Wallet} and manipulating the transaction Bybit's signers approved. It was the largest crypto theft at the time, more than twice the size of any previous hack.
The FBI attributed the hack to North Korea within five days. Hackers laundered much of the stolen funds despite freeze attempts.
Established that modern crypto heists come from compromising infrastructure around wallets, not breaking cryptography.
The Binance attack followed a similar method — a compromised developer machine used to instruct signing infrastructure to drain wallets.
