Coinkite, a Canadian Bitcoin wallet maker, reported a significant hack that exploited a software flaw, leading to an estimated loss of $130 million. The company revealed that artificial intelligence tools failed to detect the vulnerability, which resided in the firmware where two software components interact. Coinkite urged firms using AI for security-critical code reviews to conduct immediate assessments. The breach has raised concerns about the reliability of self-custody in cryptocurrency, as hard wallets are typically considered secure. The incident has prompted scrutiny of the entire ecosystem, with potential long-term impacts on investor trust in digital assets. Coinkite noted that even advanced AI models did not identify the bug during prior reviews. The hack involved multiple attack waves, according to Galaxy Research. Coinkite emphasized the need for a better understanding of how the bug evaded detection to prevent future incidents.

Key Points: • Coinkite's Coldcard wallets were hacked, resulting in a loss of $130 million. • AI tools failed to detect the vulnerability that allowed the breach. • Immediate reviews of security-critical code are recommended for firms using AI.
