Jaff Ransomware – Update

Update July 2017! A decryption tool is now available for the Jaff Ransomware! The tool is developed by Kaspersky and called RakhniDecryptor. It can be downloaded from the following link, wrapped inside a .zip archive: RakhniDecryptor.

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:

  • Zip archive of the pcap: 2017-06-01-Jaff-ransomware-malspam-traffic.pcap.zip 213 kB (213,387 bytes)
  • Zip archive of the spreadsheet tracker: 2017-06-01-Jaff-ransomware-malspam-tracker.csv.zip 0.8 kB (837 bytes)
  • Zip archive of the emails, malware, and artifacts: 2017-06-01-Jaff-ransomware-emails-and-artifacts.zip 821 kB (820,839 bytes)

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:

  • https://takanashi[.]jp/f87346b
  • https://babil117[.]com/f87346b
  • https://easysupport[.]us/f87346b

  • https://trans-atm[.]com/f87346b
  • https://trialinsider[.]com/f87346b
  • https://wipersdirect[.]com/f87346b

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:

jaff decryptor system

When Bitcoin transactions will receive one confirmation, you will be redirected to the page for downloading the jaff decryptor

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.

Step 2: Uninstall Jaff and related software from Windows

Here is a method in few easy steps that should be able to uninstall most programs. No matter if you are using Windows 10, 8, 7, Vista or XP, those steps will get the job done. Dragging the program or its folder to the recycle bin can be a very bad decision. If you do that, bits and pieces of the program are left behind, and that can lead to unstable work of your PC, errors with the file type associations and other unpleasant activities. The proper way to get a program off your computer is to Uninstall it. To do that:


1. Hold the Windows Logo Button and "R" on your keyboard. A Pop-up window will appear.


2. In the field type in "appwiz.cpl" and press ENTER.


3. This will open a window with all the programs installed on the PC. Select the program that you want to remove, and press "Uninstall"

The usually targeted registries of Windows machines are the following:

  • HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
  • HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
  • HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
  • HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce

You can access them by opening the Windows registry editor and deleting any values, created by Jaff there. This can happen by following the steps underneath:

1. Open the Run Window again, type "regedit" and click OK.


2. When you open it, you can freely navigate to the Run and RunOnce keys, whose locations are shown above.


3. You can remove the value of the virus by right-clicking on it and removing it.
Tip: To find a virus-created value, you can right-click on it and click "Modify" to see which file it is set to run. If this is the virus file location, remove the value.

IMPORTANT!
Before starting "Step 4", please boot back into Normal mode, in case you are currently in Safe Mode.
This will enable you to install and use SpyHunter 5 successfully.
