What is Reetner ransomware virus?

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 FortectIntego can be used to complete the elimination process safely.

Reetner ransomware virus illustrationReetner virus infiltrates PCs and replaces desktop background picture with the ransom note you can see in the image above.

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.

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.

How to prevent from getting ransomware

Do not let government spy on you

The government has many issues in regards to tracking users' data and spying on citizens, so you should take this into consideration and learn more about shady information gathering practices. Avoid any unwanted government tracking or spying by going totally anonymous on the internet. 

You can choose a different location when you go online and access any material you want without particular content restrictions. You can easily enjoy internet connection without any risks of being hacked by using Private Internet Access VPN.

Control the information that can be accessed by government any other unwanted party and surf online without being spied on. Even if you are not involved in illegal activities or trust your selection of services, platforms, be suspicious for your own security and take precautionary measures by using the VPN service.

Backup files for the later use, in case of the malware attack

Computer users can suffer from data losses due to cyber infections or their own faulty doings. Ransomware can encrypt and hold files hostage, while unforeseen power cuts might cause a loss of important documents. If you have proper up-to-date backups, you can easily recover after such an incident and get back to work. It is also equally important to update backups on a regular basis so that the newest information remains intact – you can set this process to be performed automatically.

When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware strikes out of nowhere. Use Data Recovery Pro for the data restoration process.
