Crypto security losses reached $2.68 billion in 2026 so far in CertiK’s broader dashboard snapshot, even as Bitcoin closed the third quarter at $83,986.47 after gaining 40% and institutional inflows into token-linked exchange-traded funds accelerated. CertiK recorded 247 incidents and $1.26 billion in losses during the third quarter, while September produced 99 incidents and $768.5 million stolen in its earlier tally, making it the year’s costliest month. The figures coexist with CertiK’s later September count of 97 incidents and roughly $768.4 million in losses, as well as other trackers’ differing methodologies. Security risks remain concentrated in crypto-native platforms despite regulated ETF demand, while CoinGecko estimated on-chain insurance capacity at $130.2 million at the end of August, down 20.2% from a year earlier. Blockaid expects attacks involving AI agents, particularly prompt injection attempts that manipulate an agent through concealed instructions.
