Recovering FMC after a Ransomware Attack

[DmitriyG]

After the Ransomware attack, our FMC VM was encrypted. The backup was unfortunately corrupted as well.
What are the methods to restore FMC from a working Firepower or something like that? Or should we do a clean installation of FMC?

@DmitriyG hi, i suggest clean installation if you have configuration backup with you. because there may or may not be compatible descriptors. because there will be no no issue in traffic without FMC. so go with clean install. and make sure to harden device settings to avoid another attack.
