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. 

“If you build a cybercrime empire, we will find you, dismantle your operation, and hold you accountable,” Attorney Pirro added. 

The DOJ said: “The Racketeer Influenced and Corrupt Organizations Act conspiracy used social engineering and occasional home break-ins to obtain information that allowed the conspirators to drain their victims’ cryptocurrency wallets.” 

The crimes started after a group of online gamers became friends before working together to commit the cybercrimes, the indictment read.

Lam and co-defendants laundered the stolen bitcoin and spent it on bottle service parties, private jet rentals, security guards, luxury handbags and watches, and properties in Los Angeles, the Hamptons, and Miami. 

The defendants would spend up to $500,000 a night on parties and give away designer handbags worth tens of thousands of dollars, Tuesday’s announcement read. 

Lam was arrested in 2024 at his rental home in Miami.
