KL Virus Files of Ransomware — How to remove virus?

The Kl virus belongs with the ransomware type of malicious agent. It is recognized as member of Dharma/CrySis ransomware family. Malware of such sort encrypts all the data on your PC (images, text files, excel sheets, music, videos, etc) and appends its extra extension to every file, creating the info.txt files in each folder with the encrypted files.

Kl virus: what is known so far?

☝️ A strictly accurate denomination for the Kl is “a ransomware infection”.

The pattern of renaming is the following: [victim’s_ID][contact_email].kl. As a part of encryption, a file entitled, for example, “report.docx” will be turned into “report.docx.id-32CB317G1.[[email protected]].kl”.

In every folder with the encoded files, a info.txt text document will be found. It is a ransom money memo. It contains 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 racketeers. You can obtain this decrypting software after contacting [email protected] through email. That is it.

In the picture below, you can see what a folder with files encrypted by the Kl looks like. Each filename has the “.[victim\’s_ID][contact_email].kl” extension added to it.

How did Kl ransomware end up on my PC?

There are plenty of possible ways of ransomware injection.

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

If you open your mailbox and see letters that look just like notifications from utility services providers, delivery agencies like FedEx, Internet providers, and whatnot, but whose addresser is strange to you, beware of opening those emails. They are very likely to have a malware file 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 file transfer protocols like BitTorrent 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 reasonable to scan the directory containing the downloaded objects with the antivirus as soon as the downloading is complete.

How do I get rid of the Kl virus?

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

Sometimes tamperers would unblock several of your files so you know that they indeed have the decryption tool. Since Kl virus is a relatively new ransomware, security software designers have not yet found a way to undo its work. However, the decoding instruments are frequently updated, so the effective countermeasure may soon arrive.

Sure thing, if the malefactors do the job of encrypting someone’s essential files, the desperate person will probably fulfill their demands. Nevertheless, paying to criminals gives no guarantee that you’re getting your blocked information back. It is still dangerous. After receiving the ransom, the racketeers may deliver a wrong decryption code 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 a system restore point or the copies of your critical files in the cloud storage or at least on an external storage. Of course, that might be not enough. Your most crucial thing could be that one you were working upon when it all started. But at least it is something. It is also reasonable to scan your PC for viruses with the antivirus program after the OS is rolled back.

Kl 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, Bbbw, Maiv, Cuag, and some others. The two main differences between them and the Kl are the ransom amount and the method of encryption. The rest is the same: documents become blocked, their extensions altered, ransom notes are created in every directory containing encoded files.

Some lucky users were able to decrypt the blocked files with the aid of the free software provided by anti-malware specialists. Sometimes the hackers mistakenly send the decryption code to the wronged in the ransom note. Such an epic fail allows the victim to restore the files. But of course, one should never rely on such a chance. Make no mistake, ransomware is a bandits’ tool to lay their hands on the money of their victims.

How сan I avert ransomware attack?

Kl ransomware doesn’t have a superpower, so as any similar malware.

You can protect your PC from its infiltration within several easy steps:

• Never open any letters from unknown mailboxes with unknown addresses, or with content that has likely no connection to something you are waiting for (can you win in a lottery without participating in it?). In case the email subject is likely something you are expecting, scrutinize all elements of the suspicious letter with caution. A hoax letter will always have mistakes.
• Do not use cracked or unknown software. Trojans are often distributed as a part of cracked software, most likely under the guise of “patch” which prevents the license check. But potentially dangerous programs are difficult to distinguish from trustworthy software, as trojans sometimes have the functionality you seek. 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

🤔 Is it possible to open “.[victim\’s_ID][contact_email].kl” files?

Unfortunately, no. You need to decipher the “.[victim\’s_ID][contact_email].kl” files first. Then you will be able to open them.

🤔 I really need to decrypt those “.[victim\’s_ID][contact_email].kl” files ASAP. How can I do that?

If the “.[victim\’s_ID][contact_email].kl” files contain some really important information, then you probably have them backed up. 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.

🤔 What actions should I take if the Kl virus has blocked my computer and I can’t get the activation key.

🤔 And what should I do now?

Many of the encrypted 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 images or videos with your friends or relatives. Just ask them to send those images back to you.
• If you have initially got any of your files from the Web, you can try to do it again.
• Your messengers, social networks pages, and cloud storage might have all those files as well.
• It might be that you still have the needed files on your old computer, a laptop, cellphone, flash memory, etc.

HINT: You can use file recovery programs⁴ to get your lost data back since ransomware encodes the copies of your files, deleting the original ones. In the tutorial below, you can learn how to recover your files with PhotoRec, but be advised: you won’t be able to do it before you eradicate the virus with an anti-malware program.

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

• In the United States: On Guard Online;
• In Canada: Canadian Anti-Fraud Centre;
