The man behind one of the biggest bitcoin thefts in history this week pleaded guilty.

Malone Lam, 22, a Miami resident from Singapore, on Tuesday admitted his role as ringleader of the international crime group which stole 4,100 bitcoins — worth over $230 million at the time — to fund a life of luxury.

The U.S. Department of Justice said that from October 2023 and through at least May 2025, Lam and others hacked databases to steal crypto users’ information and con them into providing user logins and private keys. Bitcoin and other cryptocurrencies worth $245 million were taken in the theft.

On one occasion, a co-defendant broke into a residence in New Mexico and stole a hardware wallet while Lam monitored the victim’s movements by hacking their iCloud account.

“This defendant led an international network that preyed on victims through deception, invaded their privacy, and stole hundreds of millions of dollars in cryptocurrency,” U.S. Attorney Jeanine Ferris Pirro said in a statement.
