As Crypto Fortifies Tech, Hackers Exploit Human Weakness

Changpeng Zhao (CZ), founder of Binance, disclosed receiving a Google security alert indicating a potential state-sponsored cyberattack targeting his personal account, with suspicions pointing to North Korea's Lazarus Group Coinedition^[1]. The alert, reserved for high-risk users facing nation-state threats, underscores a broader trend of state-backed actors shifting focus from technical exploits to social engineering tactics CoinGabbar^[2].
