CertiK: The losses from wrench attacks have surged nearly 12 times, making operational security the new core of prevention

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 verified wrench attack incidents were recorded globally, an increase of 33.3% year-on-year; related losses amounted to 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, with home invasion incidents rising from 1 in the first half of 2025 to 20, accounting for 41% of the total incidents during the same period. Europe has become a high-frequency attack region, with 33 incidents occurring in France, accounting for 63.5% of global cases.CertiK states that as real-world risks become a significant challenge for digital asset security, businesses and high-value individuals need to establish a more comprehensive protection system. CertiK has launched operational security services to help identify risks related to the exposure of information such as identity, home, residence, and travel trajectory; at the same time, through CertiK Security Workspace, it correlates off-chain intelligence, on-chain transactions, and AML risk signals to support institutions in tracking and analyzing cybercrime activities.In addition, CertiK is strengthening cooperation with international law enforcement agencies such as Interpol and Europol to provide technical support for cross-border attack investigations and security policy research.

CertiK: In the first half of 2026, Web3 losses exceeded $1.3 billion, with attacks accelerating towards high-value targets

Web3 security company CertiK released the "Hack3D: First Half of 2026 Report." The report shows that in the first half of 2026, the Web3 ecosystem experienced a total of 344 security incidents, with cumulative losses of approximately $1.32 billion. Although this figure represents a 46.8% decrease compared to the same period last year, if we exclude the impact of the $1.45 billion security incident encountered by Bybit, the loss scale in the first half of this year has actually increased by about 28% year-on-year, indicating that the overall security environment in the industry has not seen substantial improvement.The report points out that wallet theft has become the largest type of attack causing financial losses, resulting in approximately $450 million in losses in the first half of the year; meanwhile, although the number of phishing attacks has decreased by over 50% year-on-year, the amount of losses has only decreased by about 10.8%, reflecting that attackers are increasingly targeting high-net-worth individuals and institutional targets, implementing more focused high-value attacks.In addition, code vulnerabilities remain the most frequently occurring type of attack, with related incidents reaching 204. CertiK believes that attackers are increasingly targeting long-running and outdated smart contracts that lack re-auditing.The report also shows that large-scale attack incidents continue to dominate industry losses, with the Kelp DAO and Drift Protocol incidents collectively causing approximately $577 million in losses, accounting for 44% of the total losses in the first half of the year. From the perspective of incident quantity, the impact of single attacks, and changes in attack patterns, the Web3 industry is facing increasingly complex and continuously escalating security challenges.
