What is Nozelesn ransomware? And how does it execute its attack?

Nozelesn ransomware is one of the latest data-encoding malware discovered this week. It is created solely for money-extortion purposes and seems to spread via spam emails with fake DHL invoices. According to security experts, it mostly targets users from Poland but that does not necessarily mean that it can’t infect users from other countries as well.
Soon after its infiltration, Nozelesn ransomware will initiate a series of commands that establishes a connection to its remote Command and Control server where it downloads a couple of malicious files that helps it is doing its dirty work. Some of these malicious files are also assigned to make modifications in the Windows Registry in order to allow the crypto-malware to run on every system boot. Following these changes, Nozelesn ransomware will scan the entire drive of the affected PC in search of its targeted files such as images, documents, videos, audio files, database and more. Once it finds its targeted files, it encrypts them using the AES cipher making the file inaccessible to victims. It appends the locked files with the .nozelesn extension and releases an htm file named “HOW_FIX_NOZELESN_FILES.htm” which contains the following message:
“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

Your Personal CODE:
Once victims go to the “Nozelesn decryption cabinet”, they’re presented with further instructions about file recovery. Victims are demanded to pay 0.1 BTC which is approximately $657 at the time of writing. They are then urged to copy the transaction ID into the field provided. Cybercrooks guarantee that the decryptor used to recover files will be sent within 10 days. However, you should know better than to believe such false promises for crooks can’t be trusted and more often than not, they tend to ignore victims once they get what they want. Therefore, paying the ransom is most definitely not recommended. And besides, there are other ways you can recover your files without having to pay the ransom. But before you proceed to file recovery, you must obliterate Nozelesn ransomware from your computer first.
