All the reasons you should get rid of Reetner ASAP

Reetner virus

Reetner virus is a crypto ransomware [1] , in other words, a cyber infection designed to apply complex encryption algorithms AES256 and RSA4096 to render infected computer’s files unreadable. Extortionists expect victims to pay for the data recovery in Bitcoins — a typical currency used by hackers to conceal the transactions and their identities.

Reetner is an unusual ransomware in a way that it has been put together using Modular programming [2] , meaning that the execution of its different functionalities are independent of each other. Typically, such ransomware will operate using several executables, each designed for a different purpose, for instance, scanning the PC for predetermined files, encrypting file contents and dropping the ransom note on the encrypted PC.

Naturally, the use of different executables makes it more difficult to perform the Reetner removal. Nevertheless, software like Reimage can be used to complete the elimination process safely.

Noter.exe is one of the ransomware executable samples that the virus researchers managed to get their hands on. This particular file seems to responsible for dropping the ransom note and replacing the desktop background of the infected computer. The recovery instructions of the analyzed sample were rendered in English and Spanish [3], so we can presume that English and Spanish-speaking users are among the main targets of this parasite and should be especially careful.

The ransom note consists of merely a few lines:

! All your files have been encrypted.
See the file “Unlock_My_files” located on your Desktop for detailed instructions on how to recover your files.

Don’t even consider paying the cyber criminals if you don’t want to support them in creating similar malware in the future. Just start your antivirus, remove Reetner from your PC and try to recover your files by applying our recommended data recovery solutions.

Ransomware distribution: main techniques

Virus distribution via email attachments may seem like a thing of the past, but in reality, this method is thriving, and Reetner is one of the many ransomware that puts it to use. Nevertheless, this does not mean that virus developers don’t exploit some more complex techniques for the system infiltration. Apart from spam emails, the virus may be deployed on the PC as a result of:

  • Malvertising
  • RDP attacks
  • Exploit kits
  • Trojans

You may use sophisticated security software as a shield of protecting your data from Reetner, but there is never a 100% guarantee that the attack will be prevented. Thus, we recommend obtaining some external storage drive and keeping backup copies of your files on it.
