Suspected Coldcard Attack Wave Affects 389 Bitcoin, Galaxy Research Reports

Galaxy's security research team has identified a suspected wave of attacks targeting Coldcard hardware wallets. According to Alex Thorn, the head of research at Galaxy, these attacks involve unconfirmed transactions that might give some Coldcard users a narrow window to recover their Bitcoin holdings. The specific details of the attack vector are not fully confirmed, but the potential impact on affected users is significant given the number of Bitcoin involved.

Coldcard wallets are widely used for secure Bitcoin storage, and vulnerabilities in their firmware or transaction handling could pose serious security risks. The current situation appears to be an ongoing investigation, with Galaxy advising users to exercise caution and monitor official security advisories.

The suspected attack wave has reportedly affected around 389 Bitcoin, though the precise scope and method of the attack remain unconfirmed. Users are recommended to follow best security practices, including firmware updates and transaction verification, until further details are available.

This development underscores the importance of hardware wallet security and the need for ongoing vigilance in safeguarding digital assets. As the situation develops, further updates from Galaxy and Coldcard are anticipated to clarify the nature of the threat and mitigation strategies.
