Security researchers have confirmed that a breach targeting Coldcard hardware wallets has resulted in the theft of approximately $89 million in Bitcoin from over 1,200 addresses. The attack, which appears to exploit a vulnerability in the device’s firmware or supply chain, is considered one of the largest hardware wallet breaches to date and has significant implications for cryptocurrency security.
According to initial reports from cybersecurity firms, the breach was identified after users reported unauthorized transactions from their Coldcard wallets. The attack reportedly involved malware or a manipulated firmware update that allowed hackers to drain funds directly from affected devices. The affected addresses span a wide user base, with losses estimated at up to $89 million, though the exact number of compromised wallets remains under investigation.
Coldcard, a popular hardware wallet designed for secure Bitcoin storage, has not officially confirmed the breach but has acknowledged ongoing investigations. Experts suggest that the attack may involve a supply chain compromise or a vulnerability in the firmware update process, though details are still emerging. No official statement has been issued about the scale or method of the breach.
Potential Impact on Hardware Wallet Security and User Trust
