PANews reported on June 4 that according to Cointelegraph, Web3 network security company CertiK said that cryptocurrency hackers are abandoning the use of smart contract vulnerabilities and turning to social engineering to attack users. As of 2025, the losses caused by cryptocurrency-related attacks have exceeded US$2.1 billion, with most of the losses coming from wallet thefts and phishing attacks.

CertiK co-founder Ronghui Gu said that the attack mode has shifted from code vulnerabilities to exploiting human behavior vulnerabilities. Most of the $2.1 billion in losses were caused by wallet theft, poor key management and operational problems. The industry must now invest in better wallet security and access control, as well as real-time transaction monitoring and simulation tools to reduce future incidents.
