Security Breaches: North Korean hackers, identified as the Lazarus Group or TraderTraitor, have executed the largest cryptocurrency theft to date, stealing over $1.5 billion in Ethereum from the crypto exchange Bybit. The FBI has advised cryptocurrency companies to avoid transactions with the stolen assets to hinder their conversion into other currencies. Bybit's founder has pledged compensation to affected users and offered a $140 million reward for information leading to the recovery of the stolen funds.
