T_TEN Virus 🔐 (.T_TEN Files) — How to Remove?

The T_ten virus falls within the ransomware type of malicious agent. Harmful software of such sort encrypts all user’s data on the computer (photos, text files, excel tables, music, videos, etc) and adds its own extension to every file, creating the readme.txt files in every directory with the encrypted files.

What is T_ten virus?

☝ A scientifically correct denomination for the T_ten would be “a ransomware infection”.

T_ten will add its extra .T_TEN extension to every file’s title. For instance, a file entitled “photo.jpg” will be renamed to “photo.jpg.T_TEN”. Just like the Excel table named “table.xlsx” will be changed to “table.xlsx.T_TEN”, and so forth.

In each folder containing the encrypted files, a readme.txt text file will appear. It is a ransom money note. Therein you can find information on the ways of contacting the racketeers and some other information. The ransom note usually contains a description of how to purchase the decryption tool from the ransomware developers. That is how they do it.

In the screenshot below, you can see what a directory with files encrypted by the T_ten looks like. Each filename has the “.T_TEN” extension appended to it.

How did my computer get infected with T_ten ransomware?

There are plenty of possible ways of ransomware injection.

There are currently three most popular methods for tamperers to have the T_ten virus working in your system. These are email spam, Trojan infiltration and peer networks.

If you access your mailbox and see letters that look like familiar notifications from utility services companies, postal agencies like FedEx, Internet providers, and whatnot, but whose sender is strange to you, beware of opening those emails. They are most likely to have a malicious item enclosed in them. Therefore, it is even more dangerous to open any attachments that come with letters like these.

As for the peer-to-peer networks like torrent trackers or eMule, the danger is that they are even more trust-based than the rest of the Web. You can never know what you download until you get it. Our suggestion is that you use trustworthy websites. Also, it is a good idea to scan the directory containing the downloaded objects with the anti-malware utility as soon as the downloading is finished.

How do I get rid of the T_ten virus?

It is important to inform you that besides encrypting your data, the T_ten virus will probably deploy the Azorult Spyware on your PC to get access to credentials to different accounts (including cryptocurrency wallets). The mentioned spyware2 can derive your credentials from your browser’s auto-filling cardfile.

Often criminals would decode few of your files so you know that they do have the decryption program. Since T_ten virus is a relatively new ransomware, anti-malware designers have not yet found a way to undo its work. Nevertheless, the decoding tools are frequently updated, so the effective countermeasure may soon arrive.

Sure thing, if the hackers succeed in encrypting someone’s critical files, the desperate person will most likely fulfill their demands. Nevertheless, paying to criminals does not necessarily mean that you’re getting your blocked information back. It is still risky. After obtaining the money, the racketeers may send a wrong decryption code to the victim. There were reports about racketeers simply disappearing after getting the money without even bothering to reply.

The best solution 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 storage. Surely, that might be not enough. Your most important thing could be that file you were working upon when it all went down. But at least it is something. It is also reasonable to scan your PC for viruses with the anti-malware utility after the system is rolled back.

T_ten is not the only ransomware of its kind, since there are other specimens of ransomware out there that act in the same manner. For instance, Eewt, Ofoq, Aawt, and some others. The two basic differences between them and the T_ten are the ransom amount and the method of encryption. The rest is almost identical: documents become encoded, their extensions altered, ransom notes appear in each folder containing encrypted files.

Some lucky victims were able to decode the blocked files with the aid of the free tools provided by anti-malware experts. Sometimes the hackers accidentally send the decryption key to the wronged in the ransom readme. Such an extraordinary fail allows the injured part to restore the files. But naturally, one should never rely on such a chance. Remember, ransomware is a tamperers’ instrument to lay their hands on the money of their victims.

How сan I avoid ransomware infiltration?

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

You can defend your PC from ransomware infiltration within several easy steps:

  • Ignore any letters from unknown senders with strange addresses, or with content that has nothing to do with something you are waiting for (how can you win in a lottery without even taking part in it?). In case the email subject is more or less something you are expecting, scrutinize all elements of the dubious email carefully. A fake email will always contain mistakes.
  • Never use cracked or unknown programs. Trojan viruses are often shared as an element of cracked products, possibly as a “patch” which prevents the license check. Understandably, untrusted programs are very hard to distinguish from reliable ones, because trojans may also have the functionality you need. Try searching for information about this software product on the anti-malware message boards, but the best way is not to use such software.

Frequently Asked Questions

đŸ€” How can I open “.T_TEN” files?Is it possible to open“.T_TEN” files?

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

đŸ€” The encrypted files are very important to me. How can I decrypt them quickly?

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.

đŸ€” What actions should I take if the T_ten virus has blocked my PC and I can’t get the activation key.

đŸ€” What can I do right now?

Many of the blocked files might still be at your disposal

  • If you sent or received your important files via email, you could still download them from your online mail server.
  • You may have shared photographs or videos with your friends or family members. Just ask them to send those images 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 PC, a portable device, mobile, external storage, etc.

USEFUL TIP: You can employ data recovery utilities5 to get your lost data back since ransomware encrypts 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 can do it only after 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.
