Nunchuk's public guidance thread following Block's analysis: treats any on-device Coldcard seed since 2021 as suspect pending Coinkite's full report, and refines its multisig guidance to distinguish one compromised key from a quorum composed entirely of affected Coldcard seeds. Nunchuk is also reported to have emailed subscribers before posting publicly; the email itself is not in this archive.
