The company said the initial attack activity is identifiable on-chain through this pattern, but noted that future attacks against Coldcard-generated addresses may not follow the same fingerprint.Coinkite co-founder Rodolfo Novak said in an X post on Friday that the company takes responsibility for the firmware bug and is working to determine the full scope of the issue.Novak said Coinkite released a hotfix to remove the software fallback path, but warned that the update does not protect seeds generated on vulnerable firmware.
