What is known about the Crypta3virus?

☝️ A strictly correct denomination for the Crypta3 is “a ransomware-type malicious agent”.

Crypta3 will append its own .crYptA3 extension to the name of every encrypted file. For example, a file entitled “photo.jpg” will be renamed to “photo.jpg.crYptA3”. Likewise, the Excel file named “table.xlsx” will be altered to “table.xlsx.crYptA3”, and so forth.

In every folder with the encoded files, a readme_for_unlock.txt text file will be found. It is a ransom money memo. It contains information about the ways of contacting the racketeers and some other information. The ransom note most probably contains instructions on how to purchase the decryption tool from the racketeers. That is it.

How did my computer get infected with Crypta3 ransomware?

There are many possible ways of ransomware injection.

Nowadays, there are three most exploited ways for hackers to have the Crypta3 virus working in your system. These are email spam, Trojan injection and peer-to-peer file transfer.

If you access your mailbox and see emails that look like familiar notifications from utility services providers, postal agencies like FedEx, Internet providers, and whatnot, but whose sender is unknown to you, beware of opening those letters. They are most likely to have a malicious item attached to 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 file scheme. A Trojan is a program that infiltrates into your PC disguised as something different. For instance, you download an installer for some program you need or an update for some service. But what is unpacked turns out to be a harmful program that encrypts your data. Since the installation file can have any name and any icon, you have to make sure that you can trust the source of the stuff you’re downloading. The optimal thing is to use the software companies’ official websites.

As for the peer-to-peer networks like torrents or eMule, the threat is that they are even more trust-based than the rest of the Web. You can never guess what you download until you get it. So you’d better be using trustworthy resources. Also, it is reasonable to scan the folder containing the downloaded files with the anti-malware utility as soon as the downloading is complete.

How do I get rid of the Crypta3 virus?

It is crucial to note that besides encrypting your data, the Crypta3 virus will probably install Vidar Stealer on your PC to get access to credentials to different accounts (including cryptocurrency wallets). The mentioned spyware can derive your logins and passwords from your browser’s auto-filling cardfile.

Sometimes criminals would decode few of your files to prove that they indeed have the decryption program. As Crypta3 virus is a relatively new ransomware, security software developers have not yet found a method to undo its work. Nevertheless, the decryption tools are frequently updated, so the effective countermeasure may soon be available.

Of course, if the malefactors do the job of encoding victim’s essential files, the desperate person will probably comply with their demands. Despite that, paying to criminals gives no guarantee that you’re getting your data back. It is still risky. After receiving the money, the racketeers may deliver a wrong decryption code to the victim. There were reports about ransomware developers simply vanishing after getting the money without even writing back.

The best safety measure against ransomware is to have aan OS restore point or the copies of your essential files in the cloud drive or at least on an external disk. Obviously, that might be not enough. The most important thing could be that file you were working upon when it all happened. But at least it is something. It is also advisable to scan your drives with the anti-malware utility after the system is rolled back.

There are other ransomware products, besides Crypta3, that work similarly. Examples of those are Coty, Foza, Coza, and some others. The two major differences between them and the Crypta3 are the ransom amount and the method of encryption. The rest is almost identical: files become encoded, their extensions altered, ransom notes are found in every folder containing encrypted files.

Some fortunate victims were able to decode the arrested files with the help of the free software provided by anti-malware developers. Sometimes the hackers accidentally send the decoding key to the wronged in the ransom note. Such an extraordinary fail allows the injured part to restore the files. But naturally, one should never expect such a chance. Remember, ransomware is a tamperers’ technology to pull the money out of their victims.

How to avoid ransomware infection?

Crypta3 ransomware doesn’t have a endless power, so as any similar malware.

You can defend your system from ransomware attack in several easy steps:

  • Ignore any letters from unknown mailers with unknown addresses, or with content that has likely no connection to something you are waiting for (how 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 suspicious email carefully. A hoax email will surely contain mistakes.
  • Never use cracked or unknown software. Trojans are often distributed as a part of cracked software, possibly under the guise of “patch” preventing the license check. But untrusted programs are difficult to tell from reliable ones, because trojans sometimes have the functionality you need. You can try to find information on this program on the anti-malware forums, but the best solution is not to use such programs at all.
  • And finally, to be sure about the safety of the files you downloaded, scan them with GridinSoft Anti-Malware. This software will be a powerful defense for your personal computer.

Frequently Asked Questions

🤔 How can I open “.crYptA3” files?Are the “.crYptA3” files accessible?

There’s no way to do it, unless the files “.crYptA3” 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. If not, there is still a function of System Restore but it needs a Restore Point to be previously saved. The rest of the methods require patience.

🤔 You have advised using GridinSoft Anti-Malware to get rid of the Crypta3 virus. Does it mean that all my files, currently encrypted, will be removed too?

Of course not. Unlike the ransomware program itself, the encrypted files do not jeopardize your system.

GridinSoft Anti-Malware will delete active malware from your computer. The ransomware that has infected your device is most likely still active and launching checks from time to time to arrest any new files you might create on your computer after the initial attack. As it has been mentioned above, the Crypta3 ransomware does not come alone. It installs backdoors and keyloggers that can steal your account credentials and provide criminals with easy access to your system in the future.

🤔 What actions should I take if the Crypta3 malware has blocked my PC and I can’t get the activation key.

In such an unfortunate situation, you need to have a flash memory drive with a previously 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 block this function – use Safe Mode, which allows only the vital applications to run upon system boot. Consider reading our manual on booting Windows in Safe Mode.

🤔 What could help the situation right now?

Some of the encrypted data can be found elsewhere.

  • If you exchanged your important files through email, you could still download them from your online mailbox.
  • You may 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 Internet, you can try to do 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 notebook, cellphone, flash memory, etc.

HINT: You can employ file recovery utilities3 to retrieve your lost information since ransomware blocks the copies of your files, removing the original ones. In the tutorial below, you can see how to recover your files with PhotoRec, but remember: you can do it only after you kill the ransomware itself with an antivirus 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.
