Nemty Revenge 2.0 ransomware

Nemty Revenge 2.0 ransomware is the virus coming from another strain of cryptovirus and naming itself in the ransom note text file

Nemty Revenge 2.0 ransomware is the version of the malicious file-locking virus that may this time be updated. Previously this family was known for having some flaws in the coding and other features, so it is believed that this “Revenge” version comes fixed and probably even more dangerous, as researchers like Michael Gillespie^[1] who reported this threat, might speculate. He reports that the first “_’ got removed from the traditional file marker and ransom note name used by Nemty ransomware, but this version as the previous ones have a pattern for file extensions that involve the name of this ransomware and particular identification key that gets developed for each victim separately. A similar pattern is used to name the ransom note file that is placed in various folders and on the desktop with instructions for payments and contact information.

Although Nemty Revenge 2.0 ransomware virus creators claim to have the decryption key and that the only solution for you is to contact them via [email protected], [email protected] email addresses, you shouldn’t even think about paying these crooks. There is a huge possibility that the decryption key is not going to reach you even when the ransom is transferred to the wallet of criminals.^[2]

Nemty Revenge 2.0 ransomware is the version of the already known Nemty virus that was relying on various techniques and additional payloads or scheduled system bugs. This version is not investigated in-depth yet due to lack of malware samples, but it is possible that the virus employs one fo these encryption algorithms: AES-128, RSA-2048, RSA-8192. 

Of course, the malware can be altered or even written in a different manner, so the version depends on a particular sample of Nemty Revenge 2.0 ransomware. However, there are some features common for many cryptovirus strains, and this family especially:

• additional installations of trojans, malware, programs, files;
• changes in system settings or folders;
• collecting data from the system directly like usernames, OS type, name of the device, identification key.

All these symptoms cannot be noticed by the victim because the only easily visible feature of the Nemty Revenge 2.0 ransomware is encryption when files get locked and made useless, marked with a personalized appendix. Once that is done virus delivers its ransom demanding message with a text file that shows the following:

Hackers rely on different techniques to infect machines

The most common techniques of malware distribution involve either infected files or impersonating services, companies that people know. Often people believe the phishing message, scam tactics, and fall for the trick. Email messages mainly have hacker-created sites as hyperlinks or macro-filled documents as attachments, so people easily get tricked into opening and visiting the content.

Hackers impersonate shipping services, shopping sites, providers, so the email claiming about financial information or order details seem safe and legitimate enough. However, this main technique used to drop malicious files on users’ devices is especially noted by security experts^[3] as a serious issue that people overlook.

Infected files get created when virus installation code gets embedded into a common type file like document or PDF, database, presentation. Once that file gets downloaded and opened on the machine the window suggests enabling the additional content, and one click of the button allows the launch of malware code. You should pay more attention to suspicious emails and try to clean the email box more often.
