Jaff Ransomware – Update
Jaff Ransomware – Update June 2017
Our research indicates that the ransomware is still making rounds in the wild, infecting users and encrypting their data. The ransomware is still being distributed via malicious spam from the Necurs botnet. The spam campaign delivers PDF attachments with embedded Word documents containing malicious macros. For the infection to take place, users should open the PDF attachment, agree to open the embedded Word document, and then they should enable macros on the document.
According to Malware Traffic Analysis, these are the archives currently spreading Jaff ransomware:

Jaff Ransomware – Infection
Jaff ransomware uses the latest distribution method used by Locky ransomware. That method uses a Microsoft .doc file embedded within a PDF, which is attached to a spam e-mail. If you open such a PDF, the following message will pop up:
And afterward the following window will display:
If you click on Enable Editing and right after that on Enable Content, your PC will get infected after the launch of a few commands and interaction between a C2 server (Command and Control).
Jaff ransomware might also be spreading its payload file via social media and file-sharing networks. Freeware that is spread on the Web can be presented as helpful but could also hide the malicious script for this cryptovirus. Refrain from opening files after you have downloaded them, especially if they come from places like suspicious emails and links with unknown origins. Links that are known to deliver the Jaff ransomware that you should avoid at any cost:

Instead of opening, you should scan the files with a security tool and check them for anything that seems out of place.
Jaff Ransomware – In Detail
Jaff ransomware is the name given to a virus with an encryption function. Interestingly enough, the ransomware copies the ransom payment page design of Locky virus with only changing the name and the demanded ransom sum. The extension .Jaff will get appended to all files that become locked after the encryption process is set and done.
Jaff ransomware makes entries in the Windows Registry to achieve a form of persistence, and even launch and repress processes inside the Windows Operating System. Some of these entries are designed in a way that will start the virus automatically with every launch of Windows. One registry entry reported to be implemented by this ransomware is the following:
→HKCU\Control Panel\Desktop\Wallpaper “C:\ProgramData\Rondo\WallpapeR.bmp”
The ransom note will be displayed after the encryption process is complete. It will be put in three identical files which are ReadMe.bmp, ReadMe.html and ReadMe.txt. Inside them there will be instructions. Here is how the note looks like as a .bmp image:
The text inside those two files is the following:

The above TOR payment page of the Jaff ransomware demands you to pay 1.82 Bitcoin, which equals to 3.372 US dollars at the moment of writing this article. Newer versions even ask more than 2 Bitcoin as a ransom price. However, you should NOT under any circumstances pay anything to the cybercriminals. Nobody can guarantee that you will get your files restored upon payment, nor that you won’t get your PC infected again in the future. Furthermore, giving money to criminals will likely motivate them to do more crime, like the creation of more ransomware.

Each one of the files that gets encrypted will receive the .Jaff extension appended to them as a secondary one. For example the Work.doc file will become Work.doc.jaff and the file will be inaccessible.
The encryption algorithms which are utilized by the ransomware are believed to be AES and RSA. Besides, the implemented encryption system CryptoAPI which is implemented into the Windows OS is also used for the complex encryption process.
The Jaff cryptovirus could be set to erase the Shadow Volume Copies from the Windows operating system by using the following command:
→vssadmin.exe delete shadows /all /Quiet
If the command above is executed, it will make decryption efforts harder, if you try to use a recovery method that involves the Shadow Volume Copies. Keep on reading and check out what ways you can try to potentially restore some of your files.
