⚡️ Most Common Exploit Techniques — 2025 vs 2026

Over $3.95B lost across 159 incidents in 2025 and 2026 YTD, and the dominant technique is the same in both years: someone got access to keys they shouldn't have.

Access control failures and private key compromises drove 62.8% of 2025 losses and 90.4% of 2026 losses to date. Flash loans accounted for 0.1% of 2025 losses and 0.7% in 2026. The threat landscape has shifted decisively from smart contract exploits to human and infrastructure layer failures.
