TREE NEWS update: Hardware wallet maker COLDCARD said its official X account was compromised and published a post containing a phishing link, which has since been deleted. The account has used offline 2FA with strictly limited access since 2017, and COLDCARD said it found no login, session or access records, with credentials and offline 2FA secure. The team has contacted X and is reviewing all account permissions, suspecting unauthorized platform-level or admin access.
COLDCARD X Account Hacked, Phishing Post Deleted
The detail that matters is COLDCARD's claim that no login, session or access records exist despite the breach — that points away from credential theft and toward platform-level or admin access, a vector no amount of user-side 2FA can mitigate. For a hardware wallet brand, whose entire pitch rests on self-custody security, a compromised social channel is a direct reputational exposure, since phishing links target the same users who trust the device. Whether X's investigation confirms an internal access path, and how COLDCARD tightens account permissions, is the open question.
