CertiK Hack3D Report: Web3 Losses Exceed $1.3 Billion in the First Half of 2026, Attacks Accelerate Towards High-Value Targets

Odaily, Web3 security firm CertiK has released the "Hack3D: First Half of 2026 Report." The report shows that the Web3 ecosystem experienced 344 security incidents in the first half of 2026, with cumulative losses of approximately $1.32 billion. Although this figure represents a 46.8% decrease compared to the same period last year, excluding the impact of the $1.45 billion security incident involving Bybit, the scale of losses in the first half of this year actually increased by approximately 28% year-on-year, indicating that the overall security environment in the industry has not materially improved.

The report points out that wallet theft has become the attack type causing the greatest financial loss, accounting for approximately $450 million in losses in the first half of the year. Meanwhile, although the number of phishing attacks fell by more than 50% year-on-year, the loss amount only decreased by approximately 10.8%, reflecting that attackers are shifting towards high-net-worth individuals and institutional targets, carrying out more targeted high-value attacks.

Furthermore, code vulnerabilities remain the most frequent type of attack, with 204 related incidents. CertiK believes that attackers are increasingly targeting long-running legacy smart contracts that lack re-audits. The report also shows that mega-attacks continue to dominate industry losses, with the Kelp DAO and Drift Protocol incidents alone causing approximately $577 million in losses, accounting for 44% of the total losses in the first half of the year. Looking at the number of incidents, the impact of single attacks, and the changing attack patterns, the Web3 industry is facing more complex and continuously escalating security challenges.
