The biggest hack in Crypto industry, the Bybit exchange has confirmed a major security breach resulting in the theft of approximately $1.5 billion in Ethereum.
Security researchers are strongly indicating that the notorious North Korean hacking group is likely responsible for this crypto attack. This incident marks one of the largest cryptocurrency heists in history, sending shockwaves through the digital asset market.
Details of the Hack:
- The attack targeted Bybit’s Ethereum cold wallets during a routine transfer to a warm wallet.
- Hackers employed advanced techniques to manipulate the transaction, masking the signing interface and altering smart contract logic.
- Approximately 401,000+ ETH was stolen.
Lazarus Group Suspicions:
- Blockchain analysis by firms like Arkham and investigators like ZachXBT have revealed patterns consistent with previous Lazarus Group operations.
- Similarities to the recent Phemex exchange hack have further fueled these suspicions.
- If the Lazarus group is confirmed to be the perpetrators, this would make North Korea a major holder of Ethereum.
