[ZachXBT Discloses Investigation Details: Personally Funded Infiltration of Money Laundering Network to Obtain Intelligence, Assisted in Freezing Stolen Bybit Funds] BlockBeats News, October 5: On-chain detective ZachXBT revealed on social media that he had posed as a client to infiltrate a Chinese organized crime money laundering network. This network is alleged to have laundered over $1 billion for hackers associated with the North Korea-linked Lazarus Group in multiple exploit incidents. The intelligence he gathered helped facilitate the freezing of funds and on-chain attribution related to the $1.5 billion Bybit theft incident in February 2025. After the February 2025 Bybit incident, ZachXBT discovered in public Telegram and Discord groups that numerous accounts were processing orders related to the stolen funds. He approached an operator using the alias "Jimmy Green" as a client and gradually built trust through multiple USDC and USDT exchanges. The operator later disclosed plans for fund transfers in advance and claimed that their team had laundered the majority of the stolen Bybit funds. ZachXBT stated that he chose to continue incurring approximately 5% losses on each transaction to obtain more actionable intelligence. During the investigation, he identified a Solana address cluster involving over $12 million in stolen Bybit funds, of which $442,000 USDT was subsequently frozen by Tether. He also confirmed the freezing of $332,000 USDC linked to the Poloniex theft case and traced another $3 million in fraudulent proceeds to a Huobi-associated hot wallet that was later sanctioned. The findings were submitted to private sector investigators and law enforcement agencies. ZachXBT disclosed that he personally advanced $349,700 for this case, bearing financial losses and personal risks. Since 2022, he has assisted in freezing over $75 million in assets related to North Korea-linked incidents. He also called on foundations and individuals to provide funding to support his continued investigations into cases that others might deem unfeasible.
