Recently, the Beijing Municipal People's Procuratorate released the work of the "Procuratorial Protection of Enterprises" special action of the Beijing procuratorial organs and released typical cases. In a case of embezzlement of official positions, the defendant defrauded the company of more than 140 million yuan, and the prosecution traced the virtual currency to recover the stolen goods and losses. Between 2020 and 2021, Feng took advantage of his position at a technology company's service provider and regional operations growth department to collude with Tang, Yang, and others to defraud the company's service provider of more than 140 million yuan in rewards. Yang instructed Wang and others to register multiple shell companies in his own or someone else's name, and assisted in transferring the rewards paid by the technology company to the account actually controlled by Yang. Feng commanded Tang and Yang to use eight overseas virtual currency trading platforms to convert the involved funds from RMB to virtual currency. The sources and nature of the funds were confused through overseas "mixed currency" platforms, and transferred through multiple levels in the form of virtual currency. Some of the involved funds flowed into accounts controlled by Feng and others in the form of RMB, while others were hidden by Feng and others in the form of virtual currency. The procuratorial organ, in response to the defendant's use of virtual currency to divide the spoils and mix up the flow of funds through overseas "mixed currency" platforms, compared virtual currency and legal currency one by one, conducted a two-way review, accurately identified the flow of funds, and ultimately prompted Feng to return 92 bitcoins, recovering more than 89 million yuan in stolen funds and maximizing the recovery of the economic losses of the victimized units. On September 14, 2024, the Beijing First Intermediate People's Court made a judgment, sentencing the defendants Feng and seven others to imprisonment ranging from 14 years and 6 months to 3 years for the crime of embezzlement of official positions, and imposing corresponding fines. The judgment has come into effect. In this case, the criminals utilized their professional knowledge, exploited loopholes in company procedures and systems, colluded internally and externally, and engaged in covert behavior. The procuratorial organs have launched a technology assisted review mechanism, using blockchain big data analysis tools and a "two-way review" of the flow of virtual currency and RMB, to identify the transfer paths of the money and virtual currency involved in the case, laying the foundation for prosecuting crimes and recovering losses. Locking key evidence in massive amounts of data, establishing the association between virtual identities on the internet and criminals, and effectively breaking the defendant's "offensive defensive alliance".
