The official social media account of Coldcard, a Bitcoin (BITSTAMP:BTCUSD) hardware wallet brand made by Coinkite, was compromised on October 11, 2026. Attackers published a fake security notice claiming a critical firmware vulnerability affected Mk4, Mk5, and Q wallet models, urging owners to transfer funds immediately through a malicious website.

The scheme leveraged panic lingering from late July 2026, when a device code error weakened randomness in key creation and allowed hackers to steal 1,600 to 1,800 Bitcoin, worth $100 million to $130 million. Coinkite had issued software updates requiring manual wallet migration. The fraudulent post cited those exact patch numbers to trick users into entering their 24-word seed phrases.

Coldcard reported no security breaches on its internal systems, credentials, or offline two-factor authentication. The firm requested an investigation into potential social platform access issues. Only individuals who disclosed recovery phrases on the phishing page risk losing assets. Bitcoin held steady at $82,970.

## Key points

- Coldcard's official X account was compromised on October 11, 2026, to post a fake firmware warning.
