Binance, the world's largest cryptocurrency exchange, suffered what cybersecurity analysts describe as the biggest cryptocurrency theft in history, with approximately $6.3 billion in user funds affected. The company initially suspected that an attacker's access to an employee's compromised computer enabled unauthorised withdrawals, although subsequent investigations indicated a more complex security breach involving additional entry points. Cryptocurrency companies including Tether and Circle moved quickly to freeze approximately $2.37 billion in assets, contributing to a wider industry recovery effort.

Cybersecurity firms TRM Labs and Pangolin Intelligence attributed the attack to TraderTraitor, a hacking group linked to North Korea, although Binance has not officially confirmed the perpetrators. The exchange suspended certain deposits and withdrawals and pledged to cover affected customers' losses using company reserves. The incident has prompted international law-enforcement cooperation, including assistance from the FBI and US Secret Service, while raising serious questions about cryptocurrency security and the ability of digital exchanges to protect billions of dollars in customer assets.
