What is .cum file infection?
Also referred to as DHARMA ransomware1, it modifies your documents by means of encrypting them and demanding the ransom to be paid allegedly to restore access to them. [email@example.com].cum indicates firstname.lastname@example.org as a channel for contacting the ransomware authors.
The DHARMA ransomware is active again through its new cryptovirus bearing the name of .cum. This particular virus family modifies all popular file types by means of adding the .cum extension, thus making the data absolutely unavailable. The victims simply cannot open their important documents anymore. The ransomware also assigns its unique identification key, just like all previous representatives of the virus family. As soon the file is encrypted by the ransomware, it obtains a special new extension becoming the secondary one. The file virus also generates a ransom note providing the users want instructions allegedly to restore the data.
