This type of malware encrypts files on a victim's computer and appends the .BBNM extension, rendering them inaccessible without a decryption key. Attackers typically demand a ransom in exchange for this key. You may find decryption tools on NoMoreRansom.org.
It is strongly recommended that you do not pay the ransom. Doing so does not guarantee file recovery and only encourages further criminal activity. Instead, report the incident to law enforcement and seek assistance from cybersecurity professionals.
