Sage Ransomware – Malspam and Infection Process

The Distribution and Malspam

In order for Sage ransomware to cause a successful infection, the virus uses a combination of the whole two malicious spam techniques – spammed JavaScript file that downloads and installs the virus and a Word document with malicious macros. The files usually contain completely randomly generated names and they are archived in a .ZIP file. Sometimes Sage ransomware sends double zipped files (.zip in a .zip) to avoid detection, according to Brad Duncan at malware-traffic-analysis.net. The names of the zip files may be as the below-mentioned example displays:

One of the malicious files that may be contained in those zip files is a Word document with embedded malicious macros inside of it, that may be named something like 188241.doc. The document displays a coded messages and prompts to enable macros to decode it. Once the user enables them, the malicious script connects to the remote server of the cyber-criminals and downloads Sage ransomware on the computer:

Relatively the same process is conducted with the malicious JavaScript file. After the user opens it in the archive the infection takes place in the rather same manner:

At the moment of the Infection, Windows displays a User Account Control Windows which asks the user to click on Yes and does not close until this happens.

Sage Ransomware – Post-Infection and Encryption

After this has been done, the virus begins encrypting files. With the help of several commands and pre-configured code, Sage is able to render videos, music, pictures, audio files and others, completely non-openable. To make it’s presence known, this virus also appends the .sage file extension to those encrypted files, just like it’s previous version did:

The virus also drops it’s .HTML ransom note, named !Recovery_{random 3 letters}.html. It looks like the following:

Sage ransomware does not end the terror there. Malware researchers report it to also change the wallpaper of the user to further scare him. The wallpaper is very similar to the 1st version’s wallpaper:

The difference is in the actual text message, which is the following:

“*** ATTENTION! ALL YOUR FILES WERE ENCRYPTED! ***
***PLEASE READ THIS MESSAGE CAREFULLY ***
All your important and critical files as well as databases, images and videos and so on were encrypted by strong encryption.
SAGE 2.0 uses military grade elliptic curve cryptography and you have no chances restoring your files.
But if you follow our instructions we guarantee that you can restore all your files quickly.
For your convenience, we created copies of this message, named !Recovery_{random}.html on your desktop.
To get the instructions open any of this temporary links in your browser.”

Sage ransomware does not self-delete. Instead, the virus creates an executable file with a completely random name in the %Roaming% directory.

After the user opens the URL in the ransom instructions, he is led to the original Sage 2.0 web-page, which has the same well-crafted design, just like the 1.0 version had:

The virus even threatens the user that if in approximately 7 days the ransom is not paid, the price for the important files will double to 2000 dollars.

Remove Sage 2.0 Ransomware and Restore .sage Encrypted Files

Despite that Sage 2.0 may tempt you to pay the ransom, malware researchers advise not paying any form of ransom. The primary reason for this is that the criminals of this virus may not return your files and in addition to this, you support their virus to continue spreading. Instead, advices are to focus on removing the malware and saving the encrypted files whilst trying alternative methods, like the ones in step “Restore files encrypted by Sage 2.0 below”. For all of this information, you may want to refer to the removal instructions below. They are divided in Manual (for experienced in malware removal) and Automatic (recommended) removal instructions. Advices are to use an advanced anti-malware tool which will focus on performing multiple different processes which will eliminate all of the objects created by Sage 2.0 Ransomware automatically.
