SHADOW Ransomware (ran_master_som & ran_jr_som) Removal

Written by Brendan Smith

The Shadow virus falls within the ransomware type of infection. Malware of such sort encrypts all user’s data on the computer (images, documents, excel tables, music, videos, etc) and appends its own extension to every file, leaving the readme.txt text files in each folder with the encrypted files.

Shadow virus: what is known so far?

Shadow will add its extra .Shadow extension to every file’s title. For instance, an image entitled “photo.jpg” will be changed to “photo.jpg.Shadow”. In the same manner, the Excel sheet with the name “table.xlsx” will be changed to “table.xlsx.Shadow”, and so forth.

In every folder that contains the encoded files, a readme.txt file will appear. It is a ransom money memo. It contains information about the ways of paying the ransom and some other information. The ransom note most probably contains a description of how to purchase the decryption tool from the tamperers. You can get this decryptor after contacting, via email. That is how they do it.

How did my computer get infected with Shadow ransomware?

There is a huge number of possible ways of ransomware injection.

Nowadays, there are three most popular methods for malefactors to have the Shadow virus settled in your digital environment. These are email spam, Trojan infiltration and peer networks.

  • If you open your mailbox and see letters that look like familiar notifications from utility services providers, postal agencies like FedEx, Internet providers, and whatnot, but whose “from” field is strange to you, be wary of opening those letters. They are most likely to have a viral file enclosed in them. So it is even riskier to download any attachments that come with letters like these.
  • Another option for ransom hunters is a Trojan horse model. A Trojan is an object that gets into your machine disguised as something legal. For example, you download an installer of some program you want or an update for some program. However, what is unboxed turns out to be a harmful agent that encodes your data. Since the installation wizard can have any name and any icon, you have to make sure that you can trust the resource of the stuff you’re downloading. The best thing is to trust the software developers’ official websites.
  • As for the peer-to-peer networks like torrents or eMule, the danger is that they are even more trust-based than the rest of the Internet. You can never guess what you download until you get it. Our suggestion is that you use trustworthy websites. Also, it is a good idea to scan the folder containing the downloaded items with the antivirus as soon as the downloading is done.

How do I get rid of ransomware?

It is important to note that besides encrypting your files, the Shadow virus will probably install Vidar Stealer on your PC to get access to credentials to various accounts (including cryptocurrency wallets). The mentioned program can extract your logins and passwords from your browser’s auto-filling cardfile.

Sometimes racketeers would decode some of your files so you know that they do have the decryption tool. As Shadow virus is a relatively recent ransomware, safety measures designers have not yet found a way to reverse its work. Nevertheless, the anti-ransomware instruments are frequently updated, so the solution may soon be available.

Sure thing, if the criminals succeed in encoding someone’s critical files, the desperate person will probably fulfill their demands. Nevertheless, paying a ransom does not necessarily mean that you’re getting your blocked information back. It is still dangerous. After getting the money, the racketeers may deliver a wrong decryption key to the injured party. There were reports of criminals simply vanishing after getting the money without even bothering to reply.

The best countermeasure to ransomware is to have aan OS restore point or the copies of your critical files in the cloud disk or at least on an external disk. Obviously, that might be insufficient. The most important thing could be that file you were working upon when it all started. But at least it is something. It is also advisable to scan your drives with the anti-malware utility after the OS restoration.

There are other ransomware products, besides Shadow, that work similarly. For instance, Robaj, Blackskull, Bgjs, and some others. The two main differences between them and the Shadow are the ransom amount and the encoding method. The rest is almost identical: documents become encrypted, their extensions changed, ransom notes emerge in every folder containing encoded files.

Some lucky people were able to decrypt the arrested files with the help of the free software provided by anti-malware specialists. Sometimes the hackers accidentally send the decryption code to the wronged in the ransom note. Such an epic fail allows the victim to restore the files. But naturally, one should never expect such a chance. Remember, ransomware is a criminals’ instrument to lay their hands on the money of their victims.

How do I avert ransomware injection?

Shadow ransomware has no superpower, neither does any similar malware.

You can armour your computer from its attack within three easy steps:

  • Ignore any letters from unknown mailers with strange addresses, or with content that has nothing to do with something you are waiting for (can you win in a lottery without even taking part in it?). If the email subject is more or less something you are waiting for, scrutinize all elements of the suspicious email with caution. A hoax email will surely contain a mistake.
  • Avoid using cracked or unknown programs. Trojan viruses are often spreaded as a part of cracked software, most likely under the guise of “patch” preventing the license check. Understandably, untrusted programs are very hard to distinguish from trustworthy software, as trojans sometimes have the functionality you seek. Try to find information about this program on the anti-malware forums, but the best way is not to use such programs at all.
  • And to be sure about the safety of the files you downloaded, check them with GridinSoft Anti-Malware. This program will be a powerful shield for your system.

Frequently Asked Questions

🤔 How can I open “.Shadow” files?Are the “.Shadow” files accessible?

Unfortunately, no. You need to decipher the “.Shadow” files first. Then you will be able to open them.

🤔 What should I do to make my files accessible as fast as possible?

If the “.Shadow” files contain some really important information, then you probably have them backed up. In case you haven’t, there is still a chance that you do have a Restore Point from some time ago to roll back the whole system to the moment when it had no virus yet, but already had your files. The rest of the methods require patience.

🤔 Will GridinSoft Anti-Malware remove all the encrypted files alongside the Shadow virus?

Absolutely not! Unlike the ransomware program itself, the encrypted files do not jeopardize your system.

GridinSoft Anti-Malware only deals with active threats. The malware that has infiltrated your device is most likely still functional and running scans from time to time to arrest any new files you might create on your PC after the attack. As it has already been said, the Shadow virus does not come alone. It installs backdoors and keyloggers that can steal your account credentials and provide malefactors with easy access to your computer after some time.

🤔 What should I do if the Shadow malware has blocked my computer and I can’t get the activation key.

In such a case, you need to prepare a flash memory drive with a pre-installed Trojan Killer. Use Safe Mode to do the cleaning. You see, the ransomware starts automatically as the system boots and encrypts any new files created or brought into your computer. To suppress this process – use Safe Mode, which allows only the vital programs to run upon system boot. Consider reading our manual on running Windows in Safe Mode.

🤔 And what should I do now?

Many of the encrypted files might still be at your disposal

  • If you sent or received your critical files through email, you could still download them from your online mailbox.
  • You might have shared photographs or videos with your friends or family members. Just ask them to post those images back to you.
  • If you have initially got any of your files from the Web, you can try doing it again.
  • Your messengers, social media pages, and cloud storage might have all those files too.
  • It might be that you still have the needed files on your old PC, a notebook, mobile, external storage, etc.

USEFUL TIP: You can employ file recovery utilities1 to retrieve your lost information since ransomware encodes the copies of your files, removing the original ones. In the tutorial below, you can see how to recover your files with PhotoRec, but be advised: you won’t be able to do it before you remove the ransomware itself with an antivirus program.
