This material is made to help you remove the Sage 2.0 ransomware virus version 2.0 and try and decrypt .sage encrypted files.

A second version of the Sage ransomware has come out in the open, after the first iteration was spotted back in December. This virus has been reported to be an evolved version of CryLocker ransomware. The Sage 2.0 ransomware virus spreads via malicious spam campaigns via different types of files and it performs heavy modification on infected system, besides encrypting it’s important files possibly with the AES encryption algorithm. For a ransom, the Sage ransomware virus wants the user to pay the large sum of 2.2 BTC or approximately 2000 dollars. If you have been infected by Sage ransomware, we urge you to read the following article and learn more about Sage ransomware, how to remove it and try decrypting the files.

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.

2. Restore files encrypted by Sage 2.0

Restore Files Encrypted by Sage 2.0

Ransomware infections like Sage 2.0 aim to encrypt your files using an encryption algorithm which may be very difficult to directly decrypt. This is why we have suggested several alternative methods that may help you go around direct decryption and try to restore your files. Bear in mind that they may not be 100% effective but they may help you little or a lot in some situations.

Method 1: Scanning your drive’s sectors by using Data Recovery software.
Another method of restoring your files is by trying to bring back your files via data recovery software. Here are some suggestions for preferred data recovery software solutions:

• Stellar Phoenix Data Recovery Technicians License(Pro version with more features)
• Stellar Phoenix Windows Data Recovery
• Stellar Phoenix Photo Recovery

Method 2: Trying Kaspersky and EmsiSoft’s decryptors.
If the first method does not work, we suggest trying to use decryptors for other ransomware viruses, in case your virus is a variant of them. The two primary developers of decryptors are Kaspersky and EmsiSoft, links to which we have provided below:

• Kaspersky Decryptors
• Emsisoft Decryptors

Urgent! It is strongly advisable to first remove the Sage 2.0 threat before attempting any decryption, since it may interfere with system files and registries. You can do the removal yourself just in 5 minutes, using an advanced malware removal tool.

Method 3: Using Shadow Explorer

To restore your data in case you have backup set up, it is important to check for shadow copies in Windows using this software if ransomware has not deleted them:

• Shadow Explorer

Method 4: Finding Sage 2.0 decryption key while it communicates it via a network sniffing software.

Another way to decrypt the files is by using a Network Sniffer to get the encryption key, while files are encrypted on your system. A Network Sniffer is a program and/or device monitoring data traveling over a network, such as its internet traffic and internet packets. If you have a sniffer set before the attack happened you might get information about the decryption key. See how-to instructions below:
