According to a report by the South China Morning Post, Sun Shengbin from the Wenzhou Public Security Bureau, and Lou Yandi and his team from the Criminal Investigation Brigade of the Zhejiang Provincial Public Security Department, detailed in the journal "Forensic Science and Technology" on June 4 the technical process by which Chinese law enforcement agencies track, seize, and freeze illegal virtual assets. The paper points out that the forensic process for crypto crimes is mainly divided into three parts: device cracking, on-chain tracking, and asset freezing. In terms of device forensics, law enforcement uses professional tools such as Meiya Pico and Pinghang for full-disk scanning and intelligent filtering, retrieving mnemonic phrases from phone memos, instant messaging apps, and image recognition. For on-chain tracking, law enforcement traces back to trading platforms by tracking transaction fees, and uses technical methods such as cross-chain analysis and mixer timestamp comparison to uncover fund flows. For asset disposal, seizure is achieved by controlling private keys to transfer assets to police multi-signature wallets or by coordinating with centralized exchanges to freeze accounts.
