🚨 Nearly 600 $BTC Stolen After Coldcard Wallet Vulnerability Exploited
A major security incident has shaken the Bitcoin community after an attacker reportedly stole 594 BTC (around $38 million) from nearly 500 Bitcoin wallets in just 25 minutes.
🔹 The attack allegedly exploited a vulnerability in Coldcard Mk3 devices, where a flaw in the wallet's seed phrase generation process made some recovery phrases predictable due to weak entropy. This allowed the attacker to reconstruct affected wallets and drain their funds.
🔹 The incident highlights that even hardware wallets are not immune to security risks if cryptographic randomness is compromised. Strong entropy during seed generation is critical to ensuring wallet security.
🔹 While the exploit appears to affect a specific generation of Coldcard Mk3 devices, users are encouraged to verify whether their wallet could be impacted and, if necessary, migrate funds to a newly generated wallet using a securely created recovery phrase.
📌 The attack serves as another reminder that wallet security depends not only on offline storage, but also on the quality of the underlying cryptographic implementation.
💬 Do you think hardware wallet manufacturers need more frequent third-party security audits to prevent incidents like this? 👇
