Published Aug 3, 06:12 AM UTC

Hackers have exploited a software flaw in Coinkite's Coldcard brand of 'cold' Bitcoin wallets, which are typically considered the safest form of cryptocurrency storage. The ongoing attack has resulted in the theft of approximately 1,367 Bitcoin tokens, valued at around US$86 million, from over 4,500 wallets. Cold wallets are offline storage devices designed to be immune to remote hacking, making this breach particularly significant. The incident highlights vulnerabilities even in hardware-based security solutions for cryptocurrency. The attack is ongoing, with tens of millions of dollars continuing to be siphoned from affected wallets.
