Coinkite has issued a security advisory warning Coldcard Mk3 users that their funds may be at risk due to a seed generation flaw. Users who generated a seed on a Mk3 running firmware 4.0.1 (March 2021) or later are advised to migrate their funds immediately to a new seed generated on an unaffected device. The warning comes as investigators probe a recent theft of 594 BTC from hundreds of single-signature wallets, though no evidence has confirmed a link between the two incidents. Coinkite has not ruled out the possibility that the Mk3 flaw may have contributed to the thefts.
