XLLM Ransomware 🔐 (.XLLM File) — Removal Guide

The Xllm virus belongs to the Chaos ransomware family. Actually, it uses its leaked codebase, same as multiple other ransomware samples. Malware of such sort encrypts all the data on your computer (images, documents, excel sheets, audio files, videos, etc) and appends its own extension to every file, creating the read_it.txt files in every folder which contains the encrypted files.

What is Xllm virus?

☝️ A scientifically accurate description for the Xllm would be “a Chaos family ransomware-type infection”.

Xllm will append its own .xllm extension to every file’s name. For example, a file entitled “photo.jpg” will be altered to “photo.jpg.xllm”. Just like the Excel file named “table.xlsx” will be changed to “table.xlsx.xllm”, and so forth.

In each folder that contains the encoded files, a read_it.txt text document will be found. It is a ransom money memo. Therein you can find information about the ways of paying the ransom and some other remarks. The ransom note most probably contains a description of how to purchase the decryption tool from the racketeers. That is it.

Xllm overview:

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

How did my machine catch Xllm ransomware?

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

Nowadays, there are three most exploited ways for criminals to have the Xllm virus working in your digital environment. These are email spam, Trojan injection and peer file transfer.

If you access your mailbox and see emails that look just like notifications from utility services providers, delivery agencies like FedEx, web-access providers, and whatnot, but whose mailer is unknown to you, be wary 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 torrent trackers or eMule, the danger 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. So you’d better be using trustworthy websites. Also, it is a good idea to scan the directory containing the downloaded files with the antivirus as soon as the downloading is complete.

How do I get rid of the Xllm virus?

It is crucial to inform you that besides encrypting your data, the Xllm virus will probably install 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.

Often racketeers would decrypt several of your files so you know that they really have the decryption tool. As Xllm virus is a relatively new ransomware, anti-malware designers have not yet found a method to reverse its work. However, the anti-ransomware instruments are frequently updated, so the effective countermeasure may soon arrive.

Understandably, if the evildoers do the job of encrypting victim’s critical data, the desperate person will probably comply with their demands. Nevertheless, paying a ransom does not necessarily mean that you’re getting your files back. It is still risky. After obtaining the money, the racketeers may deliver a wrong decryption key to the injured party. There were reports about malefactors simply disappearing after getting the ransom without even bothering to reply.

The best countermeasure to ransomware is to have a system restore point or the copies of your critical files in the cloud drive or at least on an external storage. Obviously, that might be insufficient. The most important thing could be that one you were working on when it all went down. Nevertheless, it is something. It is also reasonable to scan your PC for viruses with the antivirus program after the system restoration.

Xllm 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 Mppn, Uyit, Mbtf, and some others. The two basic differences between them and the Xllm are the ransom amount and the method of encryption. The rest is the same: files become blocked, their extensions changed, ransom notes are created in every directory containing encrypted files.

Some lucky victims were able to decrypt the blocked files with the help of the free software provided by anti-ransomware experts. Sometimes the criminals accidentally send the decoding key to the victims in the ransom readme. Such an epic fail allows the victim to restore the files. But of course, one should never expect such a chance. Remember, ransomware is a bandits’ instrument to pull the money out of their victims.

How do I avoid ransomware infection?

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

You can protect your system from its attack within several easy steps:

• Ignore any letters from unknown senders with strange addresses, or with content that has likely no connection to something you are expecting (can you win in a lottery without participating in it?). If the email subject is more or less something you are waiting for, scrutinize all elements of the dubious email with caution. A hoax email will always contain a mistake.
• Never use cracked or unknown programs. Trojans are often spreaded as an element of cracked products, possibly as a “patch” to prevent the license check. But untrusted programs are difficult to distinguish from trustworthy software, because trojans may also have the functionality you seek. Try to find information about this program on the anti-malware forums, but the optimal way is not to use such software.

Frequently Asked Questions

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

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

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

It’s good if you have fаr-sightedly saved copies of these important files elsewhere. 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. There are other ways to beat ransomware, but they take time.

🤔 What should I do if the Xllm malware has blocked my computer and I can’t get the activation key.

🤔 What could help the situation right now?

Some of the blocked files can be found elsewhere.

• If you sent or received your important files through email, you could still download them from your online mailbox.
• You might have shared images or videos with your friends or family members. Simply ask them to send those images back to you.
• If you have initially downloaded any of your files from the Internet, you can try downloading them again.
• Your messengers, social media pages, and cloud disks might have all those files too.
• Maybe you still have the needed files on your old PC, a portable device, phone, external storage, etc.

USEFUL TIP: You can employ data recovery utilities⁵ to get your lost data back since ransomware arrests the copies of your files, removing the authentic ones. In the tutorial below, you can learn how to recover your files with PhotoRec, but remember: you can do it only after you eradicate the ransomware itself 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;
• In the United Kingdom: Action Fraud;
• In Australia: SCAMwatch;
• In New Zealand: Consumer Affairs Scams;
• In France: Agence nationale de la sécurité des systèmes d’information;
• In Germany: Bundesamt für Sicherheit in der Informationstechnik;
• In Ireland: An Garda Síochána;

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.
