A critical security flaw has been uncovered in Coldcard hardware wallets, persisting unnoticed for five years. According to CoinTelegraph, the bug was due to auditors confirming the existence of the intended random number generator but failing to verify whether it was actually being utilized.
This oversight allowed the vulnerability to remain undetected since the random number generator was never properly called during operation. Coldcard, a notable name in crypto security, and Kraken, a leading exchange, highlight the importance of thorough verification in hardware wallet audits.
For Japanese investors and traders, this discovery underscores the need for rigorous security checks in crypto asset management tools, especially as hardware wallets remain a primary defense against digital theft in the FX and crypto markets.
