Coom Virus – Details

The Coom mean a ransomware-type infection. Coom was elaborated particularly to encrypt all major file types. When the file is encrypted people are not able to use them. Coom adds the “.coom” extension for each file encrypted by it. For example, the file “myphoto.jpg“, once encrypted by Coom, will be renamed into “myphoto.jpg.coom“. As soon as the encryption is completed, Coom places a special text file into every folder containing the encrypted data.

The message given by Coom text file requesting for the ransom is absolutely the same as the statements given by other ransomware representatives. It literally discusses that the info is encrypted which the only way to restore it is to use a a distinct decryption key. Sadly, this is definitely true. The type of cryptography mechanism applied by Coom is still not correctly examined. Still, it is definitely particular that each victim may be given the specific decryption key, which is completely distinct. It is impossible to bring back the files without the key available.

Another trick of Coom is that the victims cannot get to the key. The key is saved on a specific server run by the frauds related to Coom ransomware. To get the key and recover the important information people have to pay the ransom.
