CoinGecko Says Crypto Hacks Cost $3.63 Billion Over 19 Months

The report finds most losses came from infrastructure and private‑key failures that routine smart‑contract audits and shrinking onchain insurance did not cover.

Overview

  • The CoinGecko State of Crypto Security report, published Aug. 27, 2026, tallied $3.63 billion lost across 245 incidents from January 2025 through July 2026.
  • A tiny number of mega‑breaches drove most damage with the ten largest attacks accounting for about 72.5% of the total stolen value.
  • Security audits were common but limited: 147 hacked platforms had prior independent audits and those platforms accounted for 88.44% of reported losses.
  • Only about 11% of incidents involved flaws inside routine smart‑contract audit scopes, representing roughly $396 million, while infrastructure and supply‑chain failures caused more than $1.8 billion in losses.
  • Onchain insurance capacity declined to $130.2 million and cumulative payouts stayed near $33 million, leaving exchanges and users to rely more on self‑funded protection pools and proof‑of‑reserves.
