Cointelegraph reported earlier that July had emerged as the second-worst month of 2026 for cryptocurrency thefts, largely due to a Coldcard exploit.
Hackers stole $247.4 million in crypto in July, the most this year after the $644 million stolen in April, according to DefiLlama data.
The Coldcard exploit was the month’s biggest exploit, with at least $100 million in Bitcoin (BTC) stolen from 7,300 wallets across three confirmed attack waves, according to Galaxy Digital.
The company also identified a suspected fourth wave that could bring total losses to about $130 million.
DefiLlama’s hack tracker estimated losses tied to the Coldcard exploit at $115 million.
