Besides this technique for spreading, the .Do_not_change_the_file_name.cryp file ransomware, may also take advantage of several other methods such as embedding malicious scripts in spammed web links all over the web and also have loaders posing as game patches, cracks and updates.

.Do_not_change_the_file_name.cryp Virus – Activity

For the activity of this infection, it uses multiple distribution sites, to which it’s loader may connect after already infecting your computer. Then, the loader may drop multiple different types of files. These very files may have the same names as processes that are completely legitimate or completely random names. They may be located in the usually targeted Windows folders, for example:

After the malicious files of this virus are dropped on the computer of the user, they may exhibit different activity on the computer of the user. One of the actions that may be performed by the .Do_not_change_the_file_name.cryp threat is to force delete the shadow volume copies of the encrypted computer. This is usually achievable by executing the vssadmin and bcedit commands in Windows Command Prompt in the background, without the user noticing it is happening:

In addition to this activity, the ransomware infection may also modify the Windows Registry Editor by adding malicious value strings in the Run or RunOnce sub-keys which run it’s malicious executables automatically:

.Do_not_change_the_file_name.cryp Files And Their Encryption

Regarding the encryption process of this ransomware infection, one or more encryption modes may be used. Among the suspected encryption algorithms may be among the following:

  • RSA(Rivest-Shamir-Adleman).
  • SHA(Secure Hash Algorithm).
  • AES(Advanced Encryption Standard).
  • ECDH(Elliptic Curve Diffie–Hellman).
  • Other less sophisticated ciphers.

In addition to those ciphers an encryption mode known as RC4 may or may not be employed. For the process, the .Do_not_change_the_file_name.cryp virus targets specific files to encode. Among those files may be the following file types:


The encryption process consists of replacing portons data from the original files with data from the cipher being used. After encryption, the files may appear like the following:

The encrypted files may also be encoded with a mode that is set to break them when they are modified, for example with changed filenames. The other scenario is if the cyber-criminals are just claiming this in the ransom note as a scare tactic, not to try and decrypt the encoded files. The ransom note opened after the encryption process has finished is called how_to_decode_files!!!.txt and has the following content:

ATTENTION!!! Changing the file name makes the restore process impossible!
Your data is encrypted.
To receive a program of decoding, You need to pay ~ $ 400 and
You need to send the personal code:
