This article is created to help you remove Sage 2.2 ransomware virus from your computer and try to restore files encrypted with the .sage file extension added to them.

“!HELP_SOS.hta” is the file which users see on every folder with important files encrypted by the latest version of Sage ransomware. This virus is from the file encryption type, meaning that it renders the files on the computers it infects unable to be opened. Sage has lately seen more popularity primarily because of the fact that the virus was reported to be spread via a very massive spam campaign of e-mail spam messages, carrying .zip archives with malicious documents or .js scripts in them. In case you have become a victim of the Sage 2.2 ransomware virus, we recommend you to read this article and learn how to remove Sage 2.2 and restore files encrypted with the .sage file extension.

Sage 2.2 Ransomware – How Does It Infect a PC

For the infection process, this version of Sage ransomware may use malicious e-mail spam that contains deceptive messages. The messages may be of various types and aim to convince potential victims into opening malicious .zip file attachments to those e-mails. Examples of deceptive topics that could be used to infect with Sage 2.2 are:

  • “Your PayPal transaction is complete.”
  • “Suspicious activity on your online bank account. (Bank Name)”.
  • “Your Invoice.”

There may be many other e-mails sent out infecting with Sage ransomware and they all may carry archives as file attachments. The archives may be randomly named, like “6207_ZIP.zip”, for example. In the .zip file, there are two types of files which cause an infection:

  • A JavaScript .js file which immediately causes an infection after being opened.
  • A Microsoft Office document .doc file which causes an infection when you click on Enable Content button to enable macros. These macros have malicious script in them.

Sage 2.2 Ransomware – What Happens After Infection

After the moment the user PC has been infected by the Sage 2.2 virus, an unsecured port may be used to connect to the cyber-criminals distribution sites and download the payload on the infected computer.

The payload of Sage 2.2 ransomware consists of multiple executable and temporary files, it may contain a .dll type of modules and it also contains the Wallapaper of Sage 2.2 ransomware and it’s “Decryption Instructions” ransom note. This ransom note is also named “!HELP_SOS.hta” and when opened, displays the following message to the victim:

“File recovery instructions
You probably noticed that you can not open your files and that some software stopped working correctly.
This is expected. Your files content is still there, but it was encrypted by “Sage 2.2 Ransomware”.
Your files are not lost, it is possible to revert them back to normal state by decrypting.
The only ay you can do that is by getting “SAGE Decrypter” software and your personal decryption key.
Using any other software which claims to be able to restore your files will result in files being damaged or destroyed.
You can purchase “SAGE Decrypter” software and your decryption key at your personal page you can access by following links.”

The ransom note of the virus also has a web link which of course leads to Sage ransomware’s decryption page, which has not changed much. The web page is still well-developed, like in the Sage 2.0 version.

Sage 2.2 Ransomware – Encryption Analysis

Regarding the encryption of the files, Sage 2.2 ransomware uses a strong encryption algorithm. This cipher renders files on the compromised computers no longer openable. The virus attacks

Once the Sage 2.2 virus detects that there are such types of files on the computers that have been infected, it immediately renders them no longer able to be opened and adds the .sage file extension to the files. The files appear like the image below:

The Sage Ransomware virus also may delete the shadow volume copies of the infected computer, in addition to the encryption of the files. This is performed to destroy any possibilities of recovering them via an administrative command, called vssadmin:

  • Yohan Torres

    CAN SOMEONE HELP ME WITH THIS?

  • Hello, for method 4 you have to either reinfect a computer and monitor the communications all the time or if you havent deleted the current virus that has infected your computer, you should try resetting it and setting wireshark to capture packets on starupt i.e. when the virus encrypts files and communicates. In the link below, there are some communications intercepted in relations to the previous Sage versions:

      there is any chance of tracking the criminals? they have a website in .onion and you can send them messages, they have to go to prison

      • unfortunately, all onion websites traffic goes through the Tor network, meaning through random machine every time. These machines are called nodes and the only ones who can track traffic this way are the people in control of the exit nodes of the Tor network, which is not just everyone.
