Remove Cum Virus (.[dagsdruyt@onionmail.org].cum Files Ransomware) – Dharma Ransomware

Cum – Ransomware

The Cum stands for a ransomware-type infection. The infection comes from the Dharma ransomware family. Cum was elaborated specifically to encrypt all major file types. Once the file is encrypted people are not able to use them. Cum adds the “.[dagsdruyt@onionmail.org].cum” extension for each file encrypted by it. For example, the file “myphoto.jpg“, as soon as encrypted by Cum, will be renamed into “myphoto.jpg.[dagsdruyt@onionmail.org].cum“. As quickly as the encryption is completed, Cum places a special text file into every folder containing the encrypted data.

The message given by Cum text file asking for the ransom is absolutely the same as the statements given by other ransomware virus representatives coming from the Dharma family. It actually mentions that the info is encrypted which the only way to restore it is to use a an unique decryption key. Sadly, this is definitely true. The kind of cryptography mechanism applied by Cum is still not appropriately examined. Still, it is absolutely certain that each victim may be given the specific decryption key, which is totally distinct. It is difficult to restore the files without the key available.

Another technique of Cum is that the victims cannot gain access to the key. The key is saved on a particular server run by the frauds associated with Cum ransomware. To get the key and recover the important info people need to pay the ransom.

Nevertheless, regardless of the requested amount, people need to stay away from paying the ransom. Cyber frauds are not fair, so they tend to entirely disregard what their victims feel about the issue, even when the payment reaches their pockets. This is why paying the ransom generally does not provide any positive result and people simply waste their money for nothing.

We strongly recommend that you do not contact these crooks and absolutely do not transfer money into their accounts. It is said to admit that there are no utilities able to crack Cum ransomware and to recover the data data free of charge. Thus, the only right decision is to recover the lost data from the available backup.
