A reported $116 million Bitcoin theft is attributed to an exploit involving Coldcard cold-storage wallets. According to coverage of the incident, attackers drained 1,816 bitcoin from 5,200 addresses. The impact is described as significant because Coldcard devices are marketed for use in “cold” storage setups designed to keep private keys offline and reduce exposure to online compromise. The reports explain that the theft is linked to a specific weakness or flaw associated with how the Coldcard wallet and its related processes handle certain operations, which the attacker leveraged to move funds out of affected addresses. The accounts of what has occurred focus on the scale of the withdrawals—both in total bitcoin moved and the number of addresses targeted—rather than on any single victim or a publicly named perpetrator. As with other cryptocurrency thefts, details about the exact technical mechanism, how wallets were initially exposed, and whether all affected users can recover remain under investigation. The incident continues to be monitored by investigators and affected users.
