The Coldcard exploit, which caused more than $100 million in losses, helped push July crypto thefts to $247 million, making it the second-worst month of 2026.
July 2026 emerged as the second-worst month for cryptocurrency thefts, with hackers stealing $247.4 million, primarily due to the Coldcard exploit. This figure surpassed the previous record of $75 million stolen in June and $60 million stolen in May. The Coldcard exploit was the month's biggest single exploit, with at least $100 million in Bitcoin stolen from 7,300 wallets across three confirmed attack waves.
DefiLlama's hack tracker estimates losses tied to the exploit at $115 million. Other significant July exploits included a $9 million hack against Bonzo Lend, $2.6 million stolen from SecondFi, $24 million from AFX, and $7.5 million stolen through the Verus Ethereum Bridge.
