On the afternoon of July 5, at the closed-door seminar on “Guarding Digital Asset Security” held by Babbitt, Wu Jiazhi, vice president of Send Shield, said that the recovery process of stolen assets was: 1. Victim address collection; 2. Tracking funds Flow direction; 3. Address label, feature identification; 4. Monitor the address of the large-value assets; 5. Identify the hacker address, request the exchange to help freeze; 6. Report the victim and obtain the letter of investigation; 7. Return the stolen funds. Wu Jiazhi said that the characteristics of the blockchain are particularly close to the funds, and it is more harmful than the theft of identity information on the Internet. In addition, there is no centralized authority on the blockchain, which also creates difficulties in retrieving funds.
