What is known about the Cyberwarriorsvirus?

☝️ A strictly accurate designation for the Cyberwarriors is “a ransomware malicious agent”.

Cyberwarriors adds its own .cyber extension to every file’s name. For instance, a file entitled “photo.jpg” will be changed to “photo.jpg.cyber”. Likewise, the Excel file with the name “table.xlsx” will be altered to “table.xlsx.cyber”, and so forth.

The ransom note usually contains instructions on how to buy the decryption tool from the tamperers. You can get this decrypting software after contacting cyberwar4@rambler.ru by email. That is how they do it.

How did my computer get infected with Cyberwarriors ransomware?

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

There are currently three most exploited ways for hackers to have ransomware settled in your system. These are email spam, Trojan infiltration and peer file transfer.

If you open your inbox and see emails that look just like notifications from utility services companies, delivery agencies like FedEx, Internet providers, and whatnot, but whose “from” field is strange to you, beware of opening those emails. They are very likely to have a harmful item attached to them. So it is even riskier to download any attachments that come with emails like these.

Another option for ransom hunters is a Trojan horse scheme2. A Trojan is an object that infiltrates into your computer disguised as something else. Imagine, you download an installer of some program you want or an update for some service. However, what is unpacked turns out to be a harmful program that compromises 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 files you’re downloading. The optimal thing is to trust the software companies’ official websites.

As for the peer file transfer protocols like BitTorrent or eMule, the threat 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 resources. Also, it is a good idea to scan the folder containing the downloaded objects with the anti-malware utility as soon as the downloading is finished.

How do I get rid of the Cyberwarriors virus?

It is crucial to inform you that besides encrypting your data, the Cyberwarriors virus will most likely install the Azorult Spyware on your computer to seize your credentials to various accounts (including cryptocurrency wallets). The mentioned spyware3 can derive your logins and passwords from your browser’s auto-filling cardfile.

Sometimes racketeers would unblock few of your files so you know that they indeed have the decryption tool. As Cyberwarriors virus is a relatively recent ransomware, anti-malware developers have not yet found a method to reverse its work. However, the decoding instruments are frequently upgraded, so the solution may soon be available.

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

The optimal safety measure against ransomware is to have aan OS restore point or the copies of your essential files in the cloud disk or at least on an external drive. Surely, that might be not enough. The most important thing could be that file you were working upon when it all happened. Nevertheless, it is something. It is also advisable to scan your drives with the antivirus program after the system restoration.

There are other ransomware products, besides Cyberwarriors, that work similarly. Examples of those are Xcmb, Dehd, Hudf, and some others. The two main differences between them and the Cyberwarriors are the ransom amount and the encoding method. The rest is almost identical: files become encoded, their extensions changed, ransom notes are found in each directory containing encoded files.

Some lucky victims were able to decode the blocked files with the help of the free software provided by anti-malware specialists. Sometimes the racketeers mistakenly send the decoding code to the victims in the ransom readme. Such an extraordinary fail allows the injured part to restore the files. But obviously, one should never rely on such a chance. Make no mistake, ransomware is a criminals’ instrument to lay their hands on the money of their victims.

How сan I avert ransomware infiltration?

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

You can armour your PC from its injection in three easy steps:

  • Ignore any emails from unknown mailers with unknown addresses, or with content that has likely no connection to something you are expecting (can you win in a money prize draw without even taking part in it?). In case the email subject is likely something you are waiting for, scrutinize all elements of the dubious letter carefully. A hoax email will always have a mistake.
  • Never use cracked or untrusted programs. Trojan viruses are often shared as an element of cracked products, most likely under the guise of “patch” preventing the license check. Understandably, dubious programs are difficult to distinguish from trustworthy software, because trojans sometimes have the functionality you need. You can try searching for information about this software product on the anti-malware forums, but the best solution is not to use such software.
  • And finally, 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 personal computer.

FAQ

🤔 How can I open “.cyber” files?Can I somehow access “.cyber” files?

There’s no way to do it, unless the files “.cyber” files are decrypted.

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

Hopefully, you have made a copy of those important files. 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.

🤔 If GridinSoft deletes the Cyberwarriors malware, will it also delete my files that were encrypted?

Absolutely not! The encrypted files are not harmful, so they won’t be deleted.

With the help of GridinSoft Anti-Malware, you can clean your system off the actual threats. The malware that has attacked your device is probably still active and launching checks from time to time to encrypt any new files you might create on your PC after the initial attack. As it has been said above, the Cyberwarriors virus comes with the company. It installs backdoors and keyloggers that can steal your account credentials and provide malefactors with easy access to your PC after some time.

🤔 What actions should I take if the Cyberwarriors ransomware has blocked my computer and I can’t get the activation code.

In such an unfortunate situation, you need to have a flash memory drive with a previously installed Trojan Killer. Use Safe Mode to execute the procedure. You see, the ransomware starts automatically as the system launches and encrypts any new files created or imported into your PC. To stop this process – use Safe Mode, which allows only the essential applications to run upon system boot. Consider reading our manual on running Windows in Safe Mode.

🤔 What can I do right now?

Some of the encrypted files can be located elsewhere.

  • If you sent or received your critical files via email, you could still download them from your online mail server.
  • You may have shared photographs or videos with your friends or relatives. Simply ask them to post those images back to you.
  • If you have initially got any of your files from the Internet, you can try doing it again.
  • Your messengers, social networks pages, and cloud drives might have all those files too.
  • It might be that you still have the needed files on your old PC, a portable device, phone, external storage, etc.

HINT: You can use data recovery utilities6 to retrieve your lost information since ransomware arrests the copies of your files, deleting the original ones. In the video below, you can learn how to recover your files with PhotoRec, but remember: you won’t be able to do it before you eradicate the virus with an antivirus program.

Also, you can contact the following governmental fraud and scam sites to report this attack:

To report the attack, you can contact local executive boards. For instance, if you live in USA, you can have a talk with FBI Local field office, IC3 or Secret Service.
