.Jaff File Virus – Distribution Ways

Jaff ransomware not only utilizes the same distribution method used by the latest Locky virus, but it even surpasses it. That could be due to the probability of using another method for distribution alongside the ones it copies. Adding more to it, Jaff also copies the obfuscation (a tactic for malware to hide itself better) from the same source (Locky). Down here the distribution, extraction and infection ways of the .Jaff file virus will be explained.

Spam e-mail campaigns are in play, spreading millions of emails, which have PDF files attached to them.
Opening the PDF file will show the following:

Inside the PDF, you will see that there is an embedded .docm file, which you will be kindly asked to open up. This is how that document file looks from the inside if you open it up:

Once loaded, you will be asked to click on “Enable Editing” and right after that on “Enable Content”. From then on a macro script is loaded that will download the malicious executable for the .Jaff File Virus. The macro commands is detected to download the virus from one of the following URL locations:

Jaff ransomware could also be distributing its payload via social media networks and file-sharing sites. Refrain from opening files after downloaded them, especially if they come from places such as suspicious emails and links from an unknown source. Beforehand, you should scan the files with a security program, at the very least.

.Jaff File Virus – Technical Expertise

.Jaff file virus is ransomware, dubbed after the extension it places on files, after it encrypts them. Many have argued that it is a variant of the notorious Locky ransomware virus (.Loptr), due to the similarities between them. However, that has been proven otherwise by malware researchers who investigated the matter and concluded that their malicious code is different.

The .Jaff file virus copies Locky in more than one way, and uses that as a complementary scare tactic. Jaff is written on the “C” programming language, and its code is far less sophisticated than Locky. Still, that doesn’t exclude the possibility of the two ransomware viruses to share the same author. According to Proofpoint researchers, the malware spam campaigns for both viruses are currently spread via the Dridex Trojan, which itself is spread by the Necurs botnet. That’s some food for thought.

The .Jaff file virus makes entries in the Windows Registry to achieve a higher level of persistence, and even could 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. A registry entry used by Jaff is:

→HKCU\Control Panel\Desktop\Wallpaper “C:\ProgramData\Rondo\WallpapeR.bmp”

The ransom note will be displayed after the encryption process finishes. The ransom note will be put inside three files, which are:

• ReadMe.bmp
• ReadMe.html
• ReadMe.txt

All three files will have almost exactly the same contents.
Here is how the note looks like from the ReadMe.html message:

From the instructions given on that ransom note, you will be pointed out to the TOR payment page of the .Jaff file virus:

The Tor page will have the same design as the one of Locky, but with some minor difference.
The payment page states the following:

Apparently the .Jaff File Virus demands you to pay 1.82 Bitcoin, which equals to 3.382 US dollars at the moment of writing this article. Despite that, you should NOT under any circumstances pay the ransom of the cybercriminals. Nobody can guarantee that you will get your files restored from paying, nor that you won’t get your computer infected again in the future. Providing money to these criminals will motivate them further in the creation of more ransomware viruses.

Each one of the files that gets encrypted will receive the same extension appended to them, and that is the .Jaff extension. The encryption algorithms which are utilized by the ransomware are believed to be AES and RSA.

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. Continue reading and see in what ways the potential restoration of your files could work.

2. Restore files encrypted by .Jaff File Virus

Restore Files Encrypted by .Jaff File Virus

Ransomware infections like .Jaff File Virus 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 .Jaff File Virus 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 .Jaff File Virus 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:
