CertiK Report: Losses from Wrench Attacks Surge Nearly 12-Fold, "Operational Security" Becomes New Prevention Core

Odaily Planet Daily News, July 22 - Web3 security company CertiK released the "2026 First Half Wrench Attack Report." The report shows that in the first half of 2026, a total of 52 publicly confirmed wrench attacks were recorded globally, a year-on-year increase of 33.3%; associated losses reached approximately $124 million, an increase of about 11.8 times compared to the same period last year.

The report points out that attackers are shifting from exploiting technical vulnerabilities to targeting asset holders and their real-world relationship networks. The number of home invasion incidents increased from 1 in the first half of 2025 to 20, accounting for 41% of the total incidents during the period. Europe has become a high-risk region for attacks, with 33 incidents occurring in France alone, representing 63.5% of global cases.

CertiK stated that as real-world risks become a significant challenge to digital asset security, enterprises and high-value individuals need to establish more comprehensive protection systems. CertiK has launched operational security services to help identify information exposure risks related to identity, family, residence, and travel trajectories. Simultaneously, through the CertiK Security Workspace, it correlates off-chain intelligence, on-chain transactions, and AML risk signals, supporting institutions in tracking and analyzing cybercriminal activities. Furthermore, CertiK is strengthening cooperation with international law enforcement agencies such as INTERPOL and Europol, providing technical support for cross-border attack investigations and security policy research.
