Malone Lam Yu Xuan (born July 19, 2004), a Singaporean national residing in Miami and Los Angeles, is the alleged ringleader of a crypto theft and money laundering enterprise responsible for stealing over $263 million across multiple victims between 2023 and 2025. He was arrested by the FBI on September 18, 2024, and faces RICO conspiracy charges in what prosecutors describe as the first Bitcoin-related RICO prosecution in U.S. history. As of early 2026, he remains in pretrial detention while negotiating a plea deal.

Tornado Cash is a decentralized, non-custodial cryptocurrency mixing protocol deployed on Ethereum in December 2019, co-founded by Roman Storm, Roman Semenov, and Alexey Pertsev. It was sanctioned by the U.S. Treasury's Office of Foreign Assets Control (OFAC) in August 2022 for allegedly laundering over $7 billion in virtual currency, including hundreds of millions stolen by North Korea's Lazarus Group; the sanctions were later lifted in March 2025 following a Fifth Circuit ruling that immutable smart contracts do not constitute sanctionable 'property' under IEEPA. All three co-founders face or have faced criminal proceedings: Pertsev was convicted in the Netherlands in May 2024 and sentenced to 64 months in prison, Storm was convicted on one of three counts in the U.S. in August 2025, and Semenov remains at large.

CoinEx is a centralized cryptocurrency exchange that suffered a major hot wallet breach on September 12, 2023, with losses estimated between $54 million and $70 million across multiple blockchains. On-chain investigators ZachXBT and Elliptic attributed the attack to the Lazarus Group (TraderTraitor), a North Korean state-sponsored threat actor, based on wallet address overlap with the contemporaneous Stake.com hack. Stolen proceeds were subsequently laundered in part through the Sinbad Bitcoin mixer, which was sanctioned by the U.S. Treasury's OFAC on November 29, 2023.
