Bitcoin prices retreated sharply on Monday following confirmation that hackers had exploited a critical software vulnerability in Coldcard hardware wallets, siphoning approximately NOK 820 million in cryptocurrency.

The breach undermines the long-held assumption that offline "cold" storage provides absolute protection against digital theft, marking a significant escalation in the sophistication of crypto-targeted cyberattacks.

The attack, which utilized artificial intelligence to bypass traditional security protocols, has sent shockwaves through the digital asset community.

Novaque CEO Shiven Moodley highlighted the incident as a stark reminder that even the most trusted security infrastructure is not immune to evolving threats.

The revelation has forced investors and institutional custodians to re-evaluate their reliance on hardware wallets as a fail-safe mechanism for asset preservation.

Market sentiment cooled as traders digested the implications of the breach.
