According to Bitcoin News, Bitcoin multisig wallet provider Nunchuk stated that some platform keys are generated by the Coldcard Mk4, but these keys are not directly used for assisted wallets. Instead, the actual keys in use are derived through custom logic. Therefore, even if an attacker creates a lookup table based on the affected Coldcard keys, the keys actually used by Nunchuk would not be immediately included. However, Nunchuk noted that if an attacker has sufficient time, it must be assumed that these derived keys could eventually fall within the scope of the lookup. https://(wublock123.com)/news/nunchuk-responds-to-coldcard-vulnerability-mk4-generated-keys-65714
