removal by Alice Woods - - | Type: Ransomware

Nozelesn virus is a cryptovirus that targets various users all over the world and makes their files useless by encrypting them

Nozelesn ransomware virus

Nozelesn ransomware is the virus that remains active and requires ransom from companies and everyday users. When it comes to ransomware-type threats the main technique used to affect the targeted device is file encryption. For this process, crypto malware employs algorithms, and them marks encoded data with .nozelesn appendix. Since the main purpose is to gain profit from ransom payments when victims' files get locked virus generates a ransom note and delivers the message in HTML file called HOW_FIX_NOZELESN_FILES.HTML. The victim is demanded to pay for the alleged decryption and file recovery, but there is no real guarantee that criminals would do that. Another distinct feature about Nozelesn virus is the initial distribution method – using fake DHL emails.

Although Nozelesn ransomware was first discovered back in summer 2018, more recent events have revealed that this virus is now focused on bigger targets like companies or services. This change is due to the opportunity to request larger ransom payments. 

Nozelesn ransomware virus places the HTML file on every folder that contains encrypted data when the encoding is done. The ransom note includes payment instructions and more details about the attack. The ransom note is called HOW_FIX_NOZELESN_FILES.htm and reads the following:

All files including videos, photos and documents on your computer are encrypted by nozelesn ransomware.
File decryption costs money.
In order to decrypt the files, you need to perform the following steps:
1. You should download and install this browser http://www.torproject.org/projects/torbrowser.html.en
2. After installation, run the browser and enter the address: lyasuvlsarvrlyxz.onion
3. Follow the instructions on the web-site. We remind you that the sooner you do, the more chances are left to recover the files.

Although Nozelesn ransomware developers promise to decrypt your files or provide the decryption key, you shouldn't trust these people. The best option is to get rid of the virus completely. To do so, you need a full system scan using Reimage because there might be additional files and programs added on the computer. 

When Nozelesn ransomware alters Windows Registry entries or adds system files, you cannot remove the threat easily; it remains persistent. Entering the Safe Mode with Networking may help for the process, so follow our suggestions below the article for these tips. 

Nozelesn virus
Nozelesn ransomware is the cryptovirus that uses AES encryption method for the initial file-locking.

In the ransom note, Nozelesn ransomware demands paying up and the amount may differ from 0.1000 Bitcoin or even up to 1BTC. We recommend avoiding any contact between you and the malware developers. Paying the ransom cannot give you positive results because, in many cases, malicious actors disappear after the payment and you lose your data/money permanently. 

You need to make sure that you remove Nozelesn ransomware entirely from the device because this threat may work in the background still. When you select the anti-malware program for the elimination, choose a reputable source and a legitimate program, so there is no risk of getting additional PUPs.

When you opt for the automatic Nozelesn ransomware removal, use anti-malware that you can rely on and possibly try a few different tools to make sure that this intruder is completely deleted from the machine. We have a few suggestions below if you need help selecting the tool.

There is a significant risk of getting malware from legitimate-looking emails

Since the beginning of virus development, the main technique to spread malware remains spam email campaigns because this method allows distributing files around the internet in a matter of minutes. When it comes to ransomware threats, this is helpful because malicious payload can be dropped once the victim opens an attached file.

Nozelesn ransomware
Nozelesn ransomware distribution techniques include fake emails from legitimate services.

The first distinct feature of the particular cryptovirus was the campaign when DHL emails named “invoice” distributed ransomware payload on computers and infected targeted devices. DHL is one of many names that malicious actors tend to use. Virus developers may include FedEx, Amazon, PayPal or eBay as the subject or sender to make the email look more legitimate.

You can avoid this infiltration if you pay more attention to details on suspicious emails. Spam email can have commercial content and intrusive ads that tell spam emails from regular emails apart. However, you need to delete emails that are sent from suspicious services, companies you are not related to or emails containing file attachments.

Those documents contain malicious macros, and you enable the script when the file gets downloaded and opened on your machine. Pay more attention to emails you were not expecting to get.

Terminate Nozelesn ransomware and make sure to clear the system

When you focus on Nozelesn ransomware removal, make sure to choose professional anti-malware tools. Programs like Reimage, SpyHunter 5Combo Cleaner or Malwarebytes can ensure best malware elimination results because during a full system scan all possibly dangerous files get indicated as malicious.

We can understand that data recovery is more important to you, but you need to remove Nozelesn ransomware and other threats from the computer before attempting any file restoring methods. Although the best tactic is to use data backups, not everyone has them up-to-date.

Nozelesn ransomware virus can encrypt your files again, so double-check if the computer is malware-free before plugging any external device or downloading data recovery tools.
