CertiK: Crypto Hacking Losses Down 47% YoY in First Half of 2026, But Ecosystem Not Safer

TechFlow News, July 6, according to a CertiK report, cryptocurrency losses in the first half of 2026 decreased by 46.8% year-on-year to $1.32 billion, but the security situation remains grim. Losses from phishing attacks in Q1 reached $508.2 million, and losses from wallet private key leaks in Q2 reached $807.5 million, of which over 70% stemmed from the KelpDAO and Drift Protocol hacking incidents; both attacks were attributed to North Korean state-sponsored hackers.

TRM Labs data shows that the number of attack incidents in the first half surged from 83 to 207, setting a new record high, with smart contract vulnerabilities accounting for 60%. CertiK warned that the decline in losses was mainly due to a single $1.4 billion Bybit hack event in the same period last year; excluding this factor, attacks are becoming "more targeted and more destructive per incident," and private key and multisig wallet management remain the most critical security risk exposures.
