Singaporean crypto ringleader admits role in $245m theft

Malone Lam, a 22-year-old Singapore citizen and former Miami resident, has pleaded guilty in Washington to leading an international cybercrime enterprise that stole and laundered cryptocurrency worth more than $245 million.

Lam admitted one count of participating in a racketeering conspiracy before US District Judge Colleen Kollar-Kotelly on Tuesday, September 8. Prosecutors said he organised a network that targeted cryptocurrency holders through social engineering scams, online intrusions and, on some occasions, break-ins at victims’ homes.

The US Attorney’s Office for the District of Columbia said the criminal enterprise operated from at least October 2023 until May 2025 and included participants based in California, Connecticut, New York, Florida and overseas. Lam, who also used several online aliases, identified targets and coordinated roles among members of the group.

One of the organisation’s largest thefts occurred in August 2024, when Lam and associates obtained more than 4,100 bitcoin from a victim in Washington. Court records say conspirators impersonated representatives of trusted companies, including Google and cryptocurrency exchange Gemini, and persuaded the victim to provide access information and authentication codes.

Those details allowed the group to gain control of the victim’s cryptocurrency holdings and transfer the bitcoin. Prosecutors have placed the value of that theft at more than $245 million for the purposes of the case, while earlier court filings valued the same 4,100 bitcoin at about $263 million at the time of the alleged transaction.

The broader racketeering case involves 18 defendants, with Lam becoming the 11th to plead guilty. Prosecutors described him as an organiser who played several roles in the enterprise and directed associates involved in obtaining credentials, moving stolen assets and laundering cryptocurrency through exchanges and other channels.

The plea marks a step in the prosecution of a network that authorities say grew out of contacts made through online gaming communities. Investigators allege members specialised in different parts of the operation, including identifying wealthy holders, impersonating corporate security staff, gaining account access and converting stolen cryptocurrency into cash or goods.

Federal authorities have pursued the case under the Racketeer Influenced and Corrupt Organizations Act, a statute more commonly associated with organised criminal enterprises. The charge allows prosecutors to treat coordinated fraud, laundering and related acts as part of one conspiracy rather than as isolated offences.

Court documents also describe occasional home invasions or break-ins used to obtain information from cryptocurrency holders. The Justice Department said the group combined those physical intrusions with deceptive calls and other social engineering methods designed to gain passwords, seed phrases, security codes and related information needed to access digital wallets.

The stolen proceeds financed extensive spending by members of the group. Authorities said the conspiracy paid for private jets, rental properties in Miami, Los Angeles and the Hamptons, luxury clothing, handbags, watches, private security and a fleet of exotic cars. Some vehicles were valued at as much as $3.8 million.

Nightclub spending was another major outlet for the proceeds. Court records cited services costing as much as $500,000 per evening, while Lam was linked to a $569,000 bill during one night at a Los Angeles club. Luxury watches purchased by members of the group were valued from about $100,000 to more than $500,000.

Lam was arrested in Miami after the August 2024 bitcoin theft. The guilty plea followed months of negotiations over whether he would accept an agreement or proceed to trial. Several alleged co-conspirators had indicated they were prepared to testify if the case went before a jury.

At the plea hearing, Lam acknowledged the prosecution’s account and entered his guilty plea to the RICO conspiracy charge. The offence carries a maximum prison term of 20 years, although the sentence will be determined later under federal law and sentencing guidelines.

Judge Kollar-Kotelly scheduled a status hearing for December 8, when the court is expected to address the next steps towards sentencing. Lam and other participants have also been ordered to repay more than $245 million in stolen funds to victims.
