Coldcard's maker Coinkite has alerted users of the Mk3 hardware wallet to a seed-generation vulnerability, urging immediate fund migration to avoid potential losses. This warning comes as cybersecurity experts probe an unexplained $38 million Bitcoin drain from a major wallet, raising alarms across the crypto community.
According to Coinkite, the risk lies in how seeds are generated on some Mk3 devices, which could expose users to theft if exploited. While the company works on firmware improvements, users are advised to transfer their assets to safer storage options promptly.
The massive $38 million loss caught the attention of several Bitcoin security analysts examining the wallet's activity. Details remain scarce, but the scale of the theft highlights ongoing threats in the hardware wallet landscape, pushing vendors and users to reassess security measures continually.
