The Nemty 2.3 Virus is actually a ransomware infection, whose main idea is to make sure that you won’t be able to use your files anymore, until you pay ransom to the cyber-criminals who are behind it. The main idea of this is that your files get blocks of their data replaced with data from the AES encryption algorithm used by the Nemty 2.3 Virus.

Nemty 3.1 then adds its own file extension and drops a ransom note file. This file’s main purpose is to get victims to pay ransom to get your files to be decrypted using the unique decryption key that is generated and held by the crooks. Read this article to learn how to remove NEMTY from your computer and learn how to recover data encoded by it.

NEMTY Ransomware Virus 3.1 – Update April 2020

New updates have already hit the Web space with the release of the latest variant of the NEMTY ransomware, namely Nemty 3.1 virus. There are changes to the ransomware note, desktop background image, and a few other minor changes, including the files which deliver the malware. In the screenshot given down here, you can see the new background, malicious archive opened and the changes to the ransom note’s text:


As you can see, the version is updated, there are still these huge encryption keys and some new information. The note states the following:

—> NEMTY 3.1 REVENUE <--- Some (or maybe all) of your files got encryped. We provide decryption tool if you pay a ransom. Don't worry, if we can't help you with decrypting - other people won't trust us. We provide test decryption, as proof that we can decrypt your data. You have 3 month to pay (after visiting the ransom page) until decryption key will be deleted from server. After 3 month no one, even our service can't make decryptor. 1) Web-Browser a) Open your browser. b) Open this link: hxxp://nemty.top/public/pay.php c) Upload this file. d) Follow the instructions. 2) Tor-Browser a) Download&Install Tor-Browser. b) Open Tor-Browser. c) Open this link: hxxp://zjoxyw5mkacojk5ptn2iprkivg5clow7 2mjkyk5ttubzxprjjnwapkad.onion/public/pay.php d) Upload this file. e) Follow the instruction.

The .txt file may differ than the online ransom instructions a bit in terms of text. No further changes are reported by malware researchers at this time. If any new information is found, this article will get duly updated.

NEMTY Virus 2.6 Released in March 2020

Security researchers discovered a new release of the Nemty ransomware family this time bearing the version number 2.6. This new NEMTY 2.6 virus has been detected in a phishing email campaign that appears to be set against Korean targets. At the moment there is no information regarding the full feature and code changes however the minor version change gives researchers several assumptions. First of all as this is not a major revision the main engine is probably the same. Minor version changes indicate a change in custom parameters in most cases: this may include the infection strategy. In this particular case the method of choice is the sending of phishing messages. The hackers can choose to either link the malware files in the contents or directly attach them.

Changes in the way the virus infects can include the inclusion of new modules or the modification of already existing ones. In many cases where such changes are implemented there may be individual malware action specific modifications. An example would be the modification of Windows Registry keys — the virus may add in new entries for itself or choose to remove certain values used by other applications or the operating system. Another example is when the engine will start to edit configuration files — they can be of user-installed applications or the operating system. The effects of this can be severe performance issues and the inability to start certain services. The newer version of the NEMTY virus code can also choose to delete additional files thereby making it very hard to restore the affected computers.

Nemty 2.6 Virus – Update March 2020

Nemty Ransomware brings a new version in March 2020. Unfortunately, the cryptovirus does not seem to stop being updated by its makers. The newest iteration is Nemty 2.6. The new extension is .NEMTY_xxxxxxx where the X-marks represent a random combination of symbols. The ransom note is called NEMTY_xxxxxxx-DECRYPT.txt and its name is generated by the same principle as observed with the extension. You can see the ransom note below:

Nemty 2.6 is just as bad and annoying as 2.3 and there are no hopes for a decryptor yet.

Love Letter Spam Nemty 2.3 Virus Distribution

A new group of Nemty 2.3 virus samples have been found to be distributed using email messages that impersonate secret lovers. This is a common technique which uses social engineering tricks in order to manipulate the victims into believing that a person is secretly in love with the recipients.

There are multiple subject lines which can be used to spread these messages:

  • Don’t tell anyone
  • I love you
  • Letter for you
  • Will be our secret
  • Can’t forget you

The email messages contain files attachment which are usually archives that will contain a dangerous file containing the virus code. They can be usually macro-infected documents or JavaScript code. When they are opened by the users the virus infection will begin.

Detailed information about some of the latest distribution tactics became available to us. It appears that the hackers behind the ransomware are using advanced methods in order to infect as many users as possible. In August 2019 one of the tactics was to deliver the threat via the Trik botnet — a powerful network of infected hosts that is also known under its alternative name Phorpiex. The hackers have customized it to send out a massive wave of SPAM email messages that use sextortion tactics. They use social engineering blackmail contents to manipulate the victims into interacting with the files (they are either linked or attached). A later update to the Trik botnet added a SMB infection component that attempts to intrude onto target users via vulnerable remote desktop software.

Nemty 2.3 Virus Ransomware – How Did I Get It and What Does It Do?

The Nemty ransomware family has been found updated with a new version, the new iteration is called Nemty 2.3 and it is possible that the new release has been created by a hacking group responsible for the prior threats. This is because the new version is a customized version meaning that the developers must have had access to the code of the previous Nemty viruses.

This gives us reasons to believe that once again the most common distribution techniques will be used once again. Usually the hackers will use those tactics that have the highest chance of infecting as many targets as possible. In the case of ransomware like the Nemty 2.3 virus this can be various phishing strategies that will scam the victims into thinking that they have received a legitimate message or service notification via email or that they have accessed a safe website. To confuse the users the criminals will use similar sounding domain names and self-signed security certificates.

Another popular scenario is the creation of virus-infected files — they can be either documents containing malicious macros (and of all popular formats) or dangerous application installers of popular software. These are the most popular files which are downloaded from the web and those that can integrate virus code in the easiest way. All of these files can be easily uploaded to different file-sharing networks like BitTorrent.

An in-depth analysis of some of the captured versions shows that the infection starts immediately after the user executes the relevant payload carrier. In the case of this particular malware a common infection causes is the opening up of a macro-infected document. A capture sample shows that Nemty 2.3 ransomware infections have been made by the running of text documents in Microsoft Word. Other formats can also carry the infection — presentations, databases and spreadsheets.

The Nemty 2.3 virus will launch an extensive malware behavior pattern which is programmed by the criminals. The extensive damages this ransomware will cause can be very difficult to recover unless the victims us a professional-grade anti-malware tool! One of the first actions done against the system is the removal of sensitive data: Shadow Volume Copies, recovery files, user backups and etc.

To completely recovery the affected computers the victims will need to use a combination of a ransomware removal program and a data recovery solution. The next step is to stop running processes based on a built-in list of apps that are to be bypassed. This includes not only security software, but also end user programs that are commonly used by the users. There is an important distinction between Nemty 2.3 and other ransomware is that it will also disable any running database servers, including enterprise installations. This particular characteristic shows that the ransomware is very suitable against corporate networks.

The analysis shows that the Nemty 2.3 virus will also be set to run every time the computer is started. This is made possible by reconfiguring the operating system configuration files and accessing the system preferences. In some cases such changes can also make it impossible to enter into some of the recovery boot options.

Given the complexity of the ransomware additional modules can be added at a later date by the hackers.

The Nemty 2.3 ransomware will feature the classical encryption phase by using a list of target file type extensions. A very strong cipher will be used to make them inaccessible to the users. However instead of marking the victim data with a single extension, each individual computer will have a different one based on the following scheme — .NEMTY_xxxxxxx. The ransomware note will be created in a similar manner: NEMTY_xxxxxxx-DECRYPT.txt.

The custom string is calculated by a special algorithm that will take various values from the compromised machines.
