Coldcard Bitcoin Exploit Swells to $88 Million as Attackers Drain Wallets

A security exploit in Coldcard Bitcoin wallets has resulted in attackers draining an estimated $88 million from user accounts. The vulnerability, which allows hackers to access and transfer funds without users' knowledge or consent, was first identified in January but remains unresolved.

Coldcard, a hardware wallet manufacturer, has acknowledged the issue but has yet to provide a timeline for fixing it.

Experts warn that users should exercise caution when using their Coldcard wallets until a solution is implemented. This includes monitoring account activity closely and taking immediate action if suspicious transactions are detected.
