ZachXBT says he infiltrated a Chinese syndicate that laundered more than $1 billion for Lazarus

ZachXBT says he posed as a client of a Chinese laundering syndicate tied to Lazarus, fronting $349,700 to gather intel that helped freeze stolen funds.

Why it matters

The account describes an investigator trading $349,700 of personal capital to gather intelligence inside a laundering network, which is a different sourcing method from public-ledger tracing and could change how freezes in North Korean-linked cases get pursued. Tether's 442,000 USDT freeze and the reported $75 million in total freezes tied to North Korean incidents since 2022 show centralised issuers acting on traced addresses. The picture of money-laundering orders being advertised in public Telegram and Discord groups, including in connection with the September 2026 Bitget incident, is a claim from one investigator that has not been independently confirmed.

What happened

Blockchain investigator ZachXBT said on October 5 that he infiltrated a Chinese organised crime syndicate by posing as a client, putting $349,700 of his own money into 15 suspicious accounts to build trust, paying a standard 5% fee per order. Decrypt reported that the money went in as 349,700 USDC on March 6, 2025, and CryptoSlate said the first trade was funded on a new Ethereum address the same day. A contact using the Telegram alias Jimmy Green told him the laundered funds were clear of freezing, shared details about moving funds ahead of time, named activity in Hong Kong and mainland China, and sent screenshots of bridges that ZachXBT matched on explorers such as THORChain. Finbold reported that the syndicate handled most of the $1.5 billion from the February 2025 Bybit exploit plus $387 million tied to the September 2026 Bitget incident, while Decrypt put the frozen Bybit-linked cluster at more than $12 million with 442,000 USDT frozen by Tether afterwards. Bitcoin.com News and CryptoSlate both traced the origin of the investigation to users in public Telegram and Discord groups who were openly advertising help with orders tied to stolen funds, and noted the same pattern with support tickets for the Bitget hack. Decrypt also reported ZachXBT's claim that his work has helped action more than $75 million in freezes tied to North Korean incidents since 2022 and that he funds it through grants and donations. Still unconfirmed by anyone but him: the syndicate's own account of the operations, and how much of the wider $1 billion he traced directly through his undercover work rather than from public blockchain data.
