Coldcard Vulnerability Leads to $114M Bitcoin Losses Over Insufficient BIP39 Randomization

Coldcard, a popular hardware wallet for Bitcoin and other cryptocurrencies, has been compromised by a vulnerability that has resulted in losses of nearly $114 million. The issue lies in the randomization of recovery phrases (BIP39) used by some users.

This is not the first time Coldcard has faced security issues, but it highlights the importance of robust wallet design and user education.
