Coldcard Security Breach: Crypto Holders Urged to Migrate Funds to New Wallets A recent security breach of Coldcard, a popular Bitcoin-only hardware wallet, has prompted a warning from community member Mishaboar to crypto holders. The breach has led to a major security vulnerability, with attackers able to systematically drain bitcoin from thousands of wallets by reproducing keys generated with weak software-based randomness. On-chain analysis identified three suspected attack waves targeting addresses generated by Coldcard, involving 4,585 addresses and a total of 1,367.05 BTC worth about $88.6 million. Users are advised to migrate their funds to a new wallet immediately and to create a new seed phrase on the new wallet. A recent security breach of Coldcard, a popular Bitcoin-only hardware wallet, has prompted a warning from community member Mishaboar to crypto holders. The breach has led to a major security vulnerability, with attackers able to systematically drain bitcoin from thousands of wallets by reproducing keys generated with weak software-based randomness. On-chain analysis identified three suspected attack waves targeting addresses generated by Coldcard, involving 4,585 addresses and a total of 1,367.05 BTC worth about $88.6 million. The stolen BTC had been dormant for an average of 3.18 years before the incident, with a median of 3.55 years, indicating that most victims were long-term holders.In response to the breach, Coldcard has issued an urgent alert to its users to upgrade their devices, generate a new seed, and carefully move their funds away from the wallet. Community member Mishaboar has also shared an important precaution for hardware wallet users, urging them to never enter their seed phrase into a computer, adding that offline backups must be kept in a safe place, with at least one copy in a different location.Users are advised to migrate their funds to a new wallet immediately and to create a new seed phrase on the new wallet. Alex Thorn, head of research at Galaxy Research, stated that attacks linked to the Coldcard vulnerability are ongoing and urged affected users who have not yet migrated their assets to move their funds as soon as possible.The vulnerability in the March 2021 Coldcard firmware release allowed attackers to systematically drain bitcoin from thousands of wallets by reproducing keys generated with weak software-based randomness.
