CertiK: Cryptocurrency Theft in the First Half of 2026 Decreased by 47% Year-on-Year, But Security Landscape Remains Unchanged

BlockBeats News, July 6th, Blockchain security company CertiK released a report stating that cryptocurrency security incidents in the first half of 2026 resulted in losses of approximately $1.32 billion, a 46.8% year-on-year decrease. However, CertiK stated that this decline is misleading and does not indicate an improvement in the industry's security posture.

The report shows that cryptocurrency attack losses in the second quarter increased by 59% to $807.5 million quarter-on-quarter, with over 70% of the losses stemming from two attacks on KelpDAO and Drift Protocol, both believed to be carried out by a North Korea-backed hacking group. Meanwhile, TRM Labs data shows that the number of security incidents in the first half of 2026 has increased from 83 in the same period last year to 207, reaching a historical high.

CertiK pointed out that private key management and multi-signature wallets remain the most critical security risk points. They recommended that protocols and institutions enhance hardware security, optimize multi-sign governance, and diversify the locations of signers to reduce the risk of attacks.
