NOZELESN Virus (.NOZELESN Files of Ransomware) — How to remove virus?

The Nozelesn virus belongs to the ransomware type of malicious agent. Ransomware of this type encrypts all the data on your computer (photos, text files, excel tables, audio files, videos, etc) and adds its own extension to every file, leaving the HOW_FIX_NOZELESN_FILES.htm text files in every folder with the encrypted files.

Nozelesn virus: what is known so far?

☝️ A scientifically accurate designation for the Nozelesn is “a ransomware-type malicious agent”.

Nozelesn will append its own .nozelesn extension to every file’s name. For example, an image entitled “photo.jpg” will be turned into “photo.jpg.nozelesn”. Likewise, the Excel table with the name “table.xlsx” will become “table.xlsx.nozelesn”, and so on.

In each directory that contains the encoded files, a HOW_FIX_NOZELESN_FILES.htm file will be found. It is a ransom money memo. Therein you can find information on the ways of contacting the racketeers and some other information. The ransom note most probably contains instructions on how to buy the decryption tool from the Nozelesn developers. That is basically the scheme of the malefaction.

Nozelesn overview:

The HOW_FIX_NOZELESN_FILES.htm document accompanying the Nozelesn malware provides the following dispiriting information:

All files including videos, photos and documents on your computer are encrypted by nozelesn ransomware.

In the picture below, you can see what a folder with files encrypted by the Nozelesn looks like. Each filename has the “.nozelesn” extension appended to it.

How did my machine catch Nozelesn ransomware?

There are plenty of possible ways of ransomware infiltration.

There are currently three most popular methods for malefactors to have the Nozelesn virus settled in your system. These are email spam, Trojan infiltration and peer file transfer.

If you access your inbox and see emails that look just like notifications from utility services providers, delivery agencies like FedEx, web-access providers, and whatnot, but whose addresser is strange to you, be wary of opening those letters. They are most likely to have a malicious file attached to them. Therefore, it is even riskier to download any attachments that come with emails like these.

As for the peer file transfer protocols like torrent trackers or eMule, the threat 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 reasonable to scan the directory containing the downloaded files with the anti-malware utility as soon as the downloading is done.

How to remove the Nozelesn virus?

It is important to inform you that besides encrypting your files, the Nozelesn virus will most likely deploy the Azorult Spyware on your machine to seize your credentials to different accounts (including cryptocurrency wallets). The mentioned spyware² can derive your logins and passwords from your browser’s auto-filling cardfile.

Often tamperers would unblock some of your files so you know that they indeed have the decryption program. As Nozelesn virus is a relatively recent ransomware, anti-malware engineers have not yet found a method to undo its work. However, the decryption tools are frequently upgraded, so the solution may soon arrive.

Understandably, if the criminals do the job of encoding someone’s critical data, the desperate person will probably comply with their demands. However, paying a ransom gives no guarantee that you’re getting your blocked information back. It is still risky. After receiving the money, the racketeers may deliver a wrong decryption key to the injured party. There were reports of ransomware developers simply vanishing after getting the money without even bothering to reply.

The optimal countermeasure to ransomware is to have aan OS restore point or the copies of your essential files in the cloud disk or at least on an external disk. Obviously, that might be insufficient. Your most important thing could be that one you were working upon when it all started. Nevertheless, it is something. It is also wise to scan your drives with the antivirus program after the OS is rolled back.

Nozelesn 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 Mljx, Hudf, Mljx, and some others. The two basic differences between them and the Nozelesn are the ransom amount and the method of encryption. The rest is almost identical: documents become inaccessible, their extensions altered, ransom notes are created in each directory containing encrypted files.

Some fortunate people were able to decode the blocked files with the help of the free tools provided by anti-ransomware experts. Sometimes the racketeers mistakenly send the decryption code to the wronged in the ransom note. Such an extraordinary fail allows the victim to restore the files. But naturally, one should never expect such a chance. Remember, ransomware is a bandits’ tool to lay their hands on the money of their victims.

How to avoid ransomware infiltration?

Nozelesn ransomware has no endless power, so as any similar malware.

You can defend your PC from ransomware injection in several easy steps:

• Ignore any letters from unknown mailboxes with unknown addresses, or with content that has likely no connection to something you are expecting (how 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, scrutinize all elements of the dubious email carefully. A fake letter will always have a mistake.
• Avoid using cracked or unknown programs. Trojan viruses are often shared as an element of cracked products, possibly under the guise of “patch” to prevent the license check. Understandably, potentially dangerous programs are difficult to distinguish from trustworthy software, as trojans may also have the functionality you need. Try to find information about this software product on the anti-malware message boards, but the best solution is not to use such software.

FAQ

🤔 How can I open “.nozelesn” files?Is it possible to open“.nozelesn” files?

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

🤔 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.

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

🤔 What can I do right now?

Some of the encrypted data can be located elsewhere.

• If you sent or received your critical files via email, you could still download them from your online mail server.
• You might have shared photographs or videos with your friends or relatives. Just ask them to give those images back to you.
• If you have initially downloaded any of your files from the Internet, you can try doing it again.
• Your messengers, social networks pages, and cloud drives might have all those files too.
• Maybe you still have the needed files on your old computer, a notebook, phone, memory stick, etc.

USEFUL TIP: You can employ data recovery utilities⁵ to get your lost data back since ransomware arrests the copies of your files, deleting the original ones. In the tutorial below, you can see how to use PhotoRec for such a restoration, but remember: you won’t be able to do it before you remove the virus with an antivirus program.

Also, you can contact the following governmental 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.
