How to Repair JPEG Images Affected by STOP/DJVU Ransomware

If you find that your JPEG images are under attack from STOP/DJVU ransomware, you're not alone. Many people face these issues with their photos and have no way to protect their pictures or access them after these attacks. If you're looking for solutions, this article is for you.

We're going to cover what the STOP/DJVU ransomware is about, how to repair JPEG images affected by STOP/DJVU ransomware malware, and how you can avoid it altogether. We have all the significant answers you need here; let's dive right in.

Part 1. What's STOP/DJVU Ransomware?

The STOP/DJVU ransomware first got attention in 2018 and has been attacking people worldwide since then. It is popular in software crack packages or adware bundles you can find on torrent sites and other platforms.

STOP/DJVU ransomware is a file encryption Trojan malware. It secretly intrudes on your computer and blocks all your files by encrypting them so that they're inaccessible to you. After it encrypts your files, it drops a ransom note notifying you of the encryption. It will ask you for some ransom money to decrypt your files and make them available t o you once again.

Here is the spreading path of stop/DjVu ransomware:

Firstly, The STOP/DJVU ransomware moves fast and targets files like office files, jpg, mp4 files, and many more. It doesn't encrypt the entire file, just about 5MB of the file. Once your files are subject to encryption, it updates the file with a .djvu extension.

Secondly, a readme.txt will also appear on your desktop. It usually contains the ransom notes and details about payment. It will also change the name of your file by adding STOP/DJVU to the file name.

Lastly, you will have to buy the decryption key from the hackers to access your jpegs.

In addition, the ransom money typically doubles if the user doesn't pay within 72 hours. So, if you are facing this kind of problem, don't hesitate to follow the instruction of this article to tackle them.

Part 2. How Did Ransomware Infect Your Computer

There are many ways the ransomware could have gained access to your computer. The virus has different ways of gaining access to your computer, and below are some of them.

Freeware Programs

A popular way that the STOP/DJVU ransomware gets into your computer and could potentially infect your files is through freeware programs. It is popular on torrent sites and many other similar platforms. When you download and install bundled freeware programs, the chances are that it includes ransomware. Be careful of torrent sites you visit on your computer and the type of freeware programs you download. 

Fake .Exe

Another popular method that ransomware gets into your computer is through fake extensions. People tend to download extensions for many reasons, and these websites use this medium to gain access to your computer. Some extensions are entirely bogus, and once they gain access to your computer, they will deliver the threat and install the malware in your computer. Once it successfully installs the malware, it then deletes itself. Watching out for the extensions you download on your computer is essential. 

Malicious Scripts

Many viruses are usually Trojan malware that delivers the ransomware to your computer. This malware also has the potential of spreading through malicious scripts. You can generally find these scrips on suspicious sites. When you click misleading apps, pops-up, or banners on these platforms, it could cause frequent redirection of your browser on the site. When you also sign up for alerts or push notifications on such platforms, it could cause the malware to gain access to your computer. 

Unsafe Networks

A popular medium that STOP/DJVU ransomware gains access to your computer is porn sites. When you visit many porn sites on unsafe networks or share files using these platforms, it could also cause infection on your computer. Visiting an unsafe network is never a good idea as it exposes your computer to many dangers on the internet. 

Part 3. How to Decrypt STOP/DJVU Ransomware Files? (7 Methods)

Once STOP/DJVU infects your files, it usually looks like there's little you can do to decrypt ransomware encrypted files and access these files beyond paying the ransom fee. What if there was a way to repair JPEG images affected by STOP/DJVU ransomware? Since you now know how it works and possible ways your computer got the infection, let's explore ways to repair JPEG images affected by STOP/DJVU ransomware.

Method 1: Isolating the infected device

Some infections encrypt your files in external storage and might even spread throughout the local networks. Therefore, it is crucial to isolate the device as soon as you discover the infection. Below are some methods to isolate the infected device.

Isolate from the internet

First of all, you have to cut off all connections to the internet. IF you're using the Ethernet, then disconnect from the motherboard. Whichever way your computer is connected to the computer, you should disconnect immediately.

You can achieve this through the control panel by visiting the network and sharing center.

Log out of cloud storage

The ransomware also has the potential to hijack your cloud storage and infect your files on the cloud. Therefore, you should immediately log out of the account. Temporarily uninstall your loud storage software till you successfully repair JPEG images affected by STOP/DJVU ransomware.

Method 2: Identify the ransomware infection

If you want to relieve your PC of this ransomware infection entirely, you must first identify it. Some of these ransomware infections send a ransom message first to introduce themselves.

However, this isn't normal, and most times, they send a direct message talking about your encrypted file and what you need to pay. One way to identify the infection s through the name of the ransom messages. This clue could be a dead-end because most names are generic and quite similar. Therefore, the ransomware name as a clue could be ineffective and cause permanent images loss.

You could also check the file extension to discover the infection it is. This clue only works when the extension is unique and not generic.

A popular method to find the infection is by using the ID ransomware website. It supports many ransomware infections. Once you upload the ransom message or affected file, it identifies the ransomware within seconds. It will also include the malware family name and other vital details. If this option doesn't work out, try using some keywords to search it out on the internet.

Method 3: Remove files associated with the virus

When an infection gains access to your computer, it will create files at different locations. These files are strategic and, most times, aim to get the malware back if you successfully remove it. That's why you need to get rid of the files as quickly as you can. To successfully do this, follow the instruction we outline below:

1. Press Window key + R buttons simultaneously on the keyboard

2. A run box will pop up, type each of these messages below and then press the OK button:

  • %AppData%

  • %LocalAppData%

  • %ProgramData%

  • %WinDir%

  • %Temp%

Look through your options on the first four for files similar to the ransomware file and remove them immediately. On the temp folder, you can simply delete all the files to be safe.
