Galaxy Head of Research: More Small-Scale Attackers and Imitators Launching Attacks Targeting Remaining Coldcard Mnemonic Phrases

TechFlow news, August 2, Galaxy Research Head Alex Thorn stated in a post that the attack incident surrounding Coldcard wallets is still evolving. Currently, more small-scale attackers and imitators have emerged, launching attacks against remaining Coldcard mnemonics. He stated that through assistance, the identity of a depositing user in one attack incident has been confirmed; the relevant funds were transferred out before the Duel platform could freeze them, and the funds involved do not belong to the three major attack waves previously identified by Galaxy Research.

Previously, the suspected Coldcard security incident sparked market concern, with multiple researchers discovering abnormal fund transfers in some wallet addresses generated by Coldcard. Galaxy Research is still continuously tracking attack addresses and reminds users still using relevant wallet seeds to take security measures as soon as possible. This incident further highlights the importance of hardware wallet security, private key management, and self-custody risk prevention.
