A Major Coldcard Wallet Flaw Went Undetected for 5 Years — Here's What That Means for Hardware Wallet Security
(60 days ago) · 1 source · Summarized by CryptoBipto
Kraken's security chief has highlighted a vulnerability in the Coldcard hardware wallet that went undetected for five years, pointing to a broader gap in how hardware wallets are tested for security flaws. The discovery raises questions about the rigor of security auditing across the hardware wallet industry.
WHY IT MATTERS
Think of a hardware wallet like a safe for your crypto — it's a physical device designed to keep your digital assets secure even if your computer gets hacked. Coldcard is one of the most well-known brands in this space, trusted by many serious Bitcoin holders. The fact that a security flaw went unnoticed in their product for five years is like discovering that a popular brand of home safes had a hidden weakness in its lock for years without anyone catching it. This matters because it shows that even the most trusted security tools need constant, rigorous testing. If you use a hardware wallet, it's a good reminder to always keep your device's software (called firmware) updated and to not assume any single security measure is perfect.
