According to data from the DefiLlama platform, hackers stole over $247 million worth of cryptocurrency in July 2026. This is the second-largest figure since the beginning of the year. So far, April remains the leader in terms of losses, with $644 million. For comparison, in June, malicious actors stole digital assets worth nearly $75 million, and in May, approximately $60 million.
The largely disappointing results for July are largely due to several exploits targeting Coldcard hardware wallets. According to Galaxy Digital, users of these devices lost over $130 million. Analysts at the company identified and confirmed three attacks on Coldcard; they also detected a fourth wave but have not yet been able to definitively confirm it. According to the DefiLlama hack tracker, hackers stole about $115 million from Coldcard owners.
July showed that even cold storage does not eliminate technological risks that can simultaneously endanger thousands of wallets, — stated CryptoRank.
However, attacks on Coldcard were not the only notable events in July. Last month also saw a $9 million hack of the Bonzo Lend DeFi protocol, a $2.6 million theft from the Cardano-based SecondFi wallet, a $24 million theft from the Arbitrum-based AFX exchange, and a $7.5 million theft via the Verus Ethereum Bridge.
