Binance Loses $6.3B in Record Crypto Heist, Feds Probe.

Hackers stole roughly $6.3 billion in cryptocurrency from Binance, the world's biggest crypto exchange, on Thursday, Oct. 29. Binance said the theft was the largest of its kind ever recorded. Some outlets put the figure closer to $6.4 billion. The exchange said the attackers compromised several systems, including an engineer's laptop, before reaching a privileged system that allowed the massive withdrawals. Binance suspended deposits and withdrawals while it investigates.

Federal agencies are involved. The FBI said it is aware of the incident and coordinating with partners to understand its scope. Tom Lynch, a spokesperson for the Secret Service's Washington Field Office, said investigators are working around the clock with partners to identify, freeze, trace and recover the stolen funds. The agency, best known for protecting the president, also investigates computer crimes and crimes involving digital currencies.

Researchers have blamed North Korea. The blockchain analysis firms TRM Labs and Chainalysis have linked the theft to TraderTraitor, an elite hacking group associated with the country. Government officials have not publicly attributed the attack in the coverage I found.

The recovery effort is moving quickly. Binance says about $3 billion has been located or frozen with partners' help. Tether said it froze nearly $1.57 billion in assets linked to the incident, and Circle froze more than $800 million. Binance has reserved about $6.34 billion of company funds to cover losses, and promised to cover all of them. The status of the remaining roughly $3.3 billion was not specified. Binance co-CEO Yi He said $3 billion represents about 2% of the company's total user assets and public reserves, and the company says customer funds are safe.

Regulators are watching. Abu Dhabi's Financial Services Regulatory Authority, which issued Binance's main operating license, said it is engaging closely with the exchange and monitoring the incident.

The heist raises an old question for crypto: whether the industry can protect enormous sums that sit behind a handful of systems and employees. For now, the focus is on tracing the money and restoring trust.
