What is known about the Cybvirus?

☝️ A strictly accurate description for the Cyb is “a VoidCrypt family ransomware-type infection”.

The renaming will be done by this pattern: .cyb. As a part of encryption, a file entitled, for instance, “report.docx” will be renamed to “report.docx.[2A-G1804A73E110].[cybcyb123@tutanota.com].cyb”.

In every folder that contains the encoded files, a Dectryption-guide.txt text file will appear. It is a ransom money memo. Therein you can find information on the ways of contacting the racketeers and some other remarks. The ransom note usually contains a description of how to buy the decryption tool from the tamperers. You can get this decryptor after contacting cybcyb123@tutanota.com, youhau@onionmail.org via email. That is it.

That is how encrypted “.cyb” files look.

How did my computer get infected with Cyb ransomware?

There are many possible ways of ransomware injection.

There are currently three most exploited ways for criminals to have ransomware planted in your digital environment. These are email spam, Trojan introduction and peer-to-peer networks.

If you access your inbox and see emails that look like familiar notifications from utility services providers, postal agencies like FedEx, web-access providers, and whatnot, but whose addresser is unknown to you, be wary of opening those emails. They are very likely to have a ransomware file enclosed in them. Therefore, it is even more dangerous to open any attachments that come with letters like these.

Another thing the hackers might try is a Trojan virus model. A Trojan is an object that infiltrates into your computer pretending to be something else. For example, you download an installer for some program you want or an update for some software. But what is unboxed turns out to be a harmful program that encrypts your data. As the installation file can have any title and any icon, you’d better be sure that you can trust the source of the stuff you’re downloading. The optimal way is to trust the software developers’ official websites.

As for the peer networks like torrent trackers or eMule, the danger is that they are even more trust-based than the rest of the Internet. You can never know what you download until you get it. So you’d better be using trustworthy resources. Also, it is a good idea to scan the folder containing the downloaded files with the anti-malware utility as soon as the downloading is finished.

How do I get rid of the Cyb virus?

It is crucial to inform you that besides encrypting your files, the Cyb virus will most likely deploy Vidar Stealer on your machine to get access to credentials to various accounts (including cryptocurrency wallets). That spyware can derive your logins and passwords from your browser’s auto-filling data.

Sometimes criminals would unblock several of your files to prove that they really have the decryption program. As Cyb virus is a relatively recent ransomware, security software developers have not yet found a method to reverse its work. However, the decryption tools are constantly updated, so the solution may soon arrive.

Sure thing, if the hackers do the job of encoding someone’s critical data, the hopeless person will most likely comply with their demands. Nevertheless, paying to criminals does not necessarily mean that you’re getting your blocked information back. It is still risky. After getting the money, the racketeers may send a wrong decryption code to the injured party. There were reports of criminals just vanishing after getting the money without even writing back.

The optimal safety measure against ransomware is to have a system restore point or the copies of your critical files in the cloud disk or at least on an external drive. Surely, that might be insufficient. Your most important thing could be that file you were working upon when it all went down. Nevertheless, it is something. It is also wise to scan your drives with the antivirus program after the system restoration.

Cyb is not the only ransomware of its kind, since there are other specimens of ransomware out there that act in the same manner. Examples of those are Coty, Foza, Coza, and some others. The two main differences between them and the Cyb are the ransom amount and the method of encryption. The rest is the same: documents become encrypted, their extensions changed, ransom notes emerge in every directory containing encoded files.

Some lucky victims were able to decode the blocked files with the help of the free software provided by anti-ransomware specialists. Sometimes the hackers mistakenly send the decryption code to the wronged in the ransom readme. Such an epic fail allows the injured part to restore the files. But of course, one should never rely on such a chance. Make no mistake, ransomware is a criminals’ instrument to pull the money out of their victims.

How do I avert ransomware attack?

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

You can armour your PC from ransomware infiltration in three easy steps:

  • Ignore any letters from unknown mailboxes with unknown addresses, or with content that has nothing to do with something you are expecting (can you win in a money prize draw without participating in it?). In case the email subject is more or less something you are waiting for, check all elements of the suspicious email with caution. A fake email will always contain a mistake.
  • Avoid using cracked or unknown software. Trojans are often distributed as a part of cracked software, possibly as a “patch” which prevents the license check. But potentially dangerous programs are difficult to distinguish from reliable software, because trojans may also have the functionality you seek. Try to find information on this software product on the anti-malware message boards, but the best way is not to use such programs at all.
  • And to be sure about the safety of the files you downloaded, scan them with GridinSoft Anti-Malware. This program will be a perfect shield for your system.

Frequently Asked Questions

🤔 Are the “.cyb” files accessible?

Negative. That is why ransomware is so frustrating. Until you decode the “.cyb” files you will not be able to access them.

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

It’s good if you have fаr-sightedly saved copies of these important files elsewhere. If not, there is still a function of System Restore but it needs a Restore Point to be previously saved. All other solutions require time.

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

Of course not. Your encrypted files are no threat to your PC.

With the help of GridinSoft Anti-Malware, you can clean your PC off the actual threats. The malware that has infiltrated your computer is must be still active and it scans your system every so often to arrest any new files you might create on your PC after the initial attack. As it has already been said, the Cyb malware does not come alone. It installs backdoors and keyloggers that can steal your account credentials and provide malefactors with easy access to your system after some time.

🤔 What to do if the Cyb virus has blocked my computer and I can’t get the activation code.

In such a case, you need to prepare a flash memory drive with a previously installed Trojan Killer. Use Safe Mode to do the cleaning. The point is that the ransomware runs automatically as the system boots and encrypts any new files created or imported into your system. To block this function – use Safe Mode, which allows only the vital programs to run automatically. Consider reading our manual on running Windows in Safe Mode.

🤔 What can I do right now?

Many of the encrypted files might still be at your disposal

  • If you exchanged your critical files through email, you could still download them from your online mail server.
  • You might have shared images or videos with your friends or family members. Just ask them to post those pictures back to you.
  • If you have initially downloaded any of your files from the Internet, you can try to do it again.
  • Your messengers, social networks pages, and cloud storage might have all those files as well.
  • Maybe you still have the needed files on your old computer, a notebook, cellphone, external storage, etc.

USEFUL TIP: You can use data recovery utilities4 to retrieve your lost information since ransomware encodes the copies of your files, removing the authentic ones. In the tutorial below, you can learn how to use PhotoRec for such a recovery, but remember: you can do it only after you eradicate the virus with an anti-malware program.

Also, you can contact the following official 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.
