NEMTY 2.2 REVENGE ransomware removal instructions

What is NEMTY 2.2 REVENGE?

Discovered by GrujaRS, NEMTY 2.2 REVENGE is an updated variant of the NEMTY REVENGE 2.0 ransomware. This malware encrypts data and demands a ransom to be paid for its decryption. During this process, all files are appended with an extension, consisting of ".NEMTY_" and a unique ID, generated individually for each victim (".NEMTY_victim's ID"). For example, a filename like "1.jpg" would appear as something similar to "1.jpg.NEMTY_JFZ9S5C", and so forth for all of the compromised files. Once this process is finished, NEMTY 2.2 REVENGE drops a text file onto the desktop, named - "NEMTY_JFZ9S5C-DECRYPT.txt" (the character string is the unique ID, therefore it differs from victim to victim).

The text file informs users that their data (or some of it) has been encrypted. Victims are told that, if they pay the ransom - they will receive decryption tools/software. Decryption will be available for three months (the countdown begins from the moment users' visit NEMTY 2.2 REVENGE website), after this period - the decryption key will be deleted. As this key is necessary for the recovery of the files, once it become unavailable - decryption is impossible. Further instructions are divided into two. The first part, instructs victims to open their browser, enter the specified website, upload "NEMTY_JFZ9S5C-DECRYPT.txt" into it and rely on the instructions therein. The second part tells users to download/install the Tor browser, open a different link though this browser, upload "NEMTY_JFZ9S5C-DECRYPT.txt" and receive more instructions. The site opened in Tor browser repeats that the victims' data has been encrypted and lists the date, until decryption ceases being a viable option. Therein the ransom (price for the decryption tools) is stated to be approximately 1000$ in Bitcoin cryptocurrency (currently - 0.14457759 BTC). This webpage also lists recommendations/instructions concerning this transaction (where to create a cryptowallet, the cyber criminals' wallet address, etc.). After this transaction is complete (the full sum has been paid), victims are told to reload the page and receive a link to the download of the necessary decryption tools/software. The website has a chat window as well, in case users need more details about this process. In most cases of ransomware infections, manual decryption using third party software - is not possible. It may only be a possibility, if the malware is still in development and/or has certain flaws/bugs. Regardless, it is expressly advised against communicating with and/or meeting the demands of cyber criminals. Often, despite paying, victims do not receive the promised tools/software, which leaves their files encrypted and worthless. To prevent NEMTY 2.2 REVENGE from further encryptions, it must be removed form the system. However, removal will not restore already affected data. The only solution can be recovering it from a backup, if one was made before the infection and stored separately.

LockBitBigBossRossMarioLocker are a few examples of other ransomware. All malicious programs within this category encrypt data and demand a ransom to be paid. Crucial differences between these infections include the cryptographic algorithm they use (symmetric or asymmetric) and the size of the payment. To protect files against data encrypting and damaging attacks - backups should be kept in remote servers and/or unplugged storage devices. Ideally, several backups should be stored in different locations.

How did ransomware infect my computer?

Ransomware and other malware mainly spreads via trojans, spam campaigns, illegal software activation ("cracking") tools, fake updaters and untrustworthy download sources (Peer-to-Peer sharing networks, unofficial and free file-hosting websites, third party downloaders and similar). Trojans are malicious programs, designed to cause chain infections (i.e. download/install additional malware). Spam campaigns are used to send deceptive emails on a mass scale. These letter are usually disguised as "official", "important", "urgent" and so on. They contain infectious files (or links leading to them), they come in formats like: archive and executable files, Microsoft Office and PDF documents, JavaScript, etc. When they are run, executed or otherwise opened - it triggers them to begin infecting the system. Rather than activate licensed product, illegal activation ("cracking") tools can download/install malicious software. Fake updaters exploit weaknesses in outdated programs and/or simply install malware instead of the updates. Untrustworthy and unreliable download channels are more likely to offer malicious content (disguised as ordinary software and/or bundled with it).

How to protect yourself from ransomware infections?

Suspicious/Irrelevant emails should not be opened, especially such received form unknown senders. All attachments (and links) found in suspect emails - must never be opened, as these files are the source of a potential infection. It is recommended to only use official and verified download channels. Software should be activated and updated with tools/functions, provided by legitimate developers. Illegal activation ("cracking") tools and third party updaters should not be used, due to high-risk of malware installation. It is paramount to have a dependable anti-virus/anti-spyware suite installed and kept updated. Furthermore, it should be used for regular system scans and removal of detected threats. If your computer is already infected with NEMTY 2.2 REVENGE, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.

select a restore point

6. In the opened window, click "Yes".

run system restore

7. After restoring your computer to a previous date, download and scan your PC with recommended malware removal software to eliminate any remaining NEMTY 2.2 REVENGE ransomware files.

To restore individual files encrypted by this ransomware, try using Windows Previous Versions feature. This method is only effective if the System Restore function was enabled on an infected operating system. Note that some variants of NEMTY 2.2 REVENGE are known to remove Shadow Volume Copies of the files, so this method may not work on all computers.

To restore a file, right-click over it, go into Properties, and select the Previous Versions tab. If the relevant file has a Restore Point, select it and click the "Restore" button.

Restoring files encrypted by CryptoDefense

If you cannot start your computer in Safe Mode with Networking (or with Command Prompt), boot your computer using a rescue disk. Some variants of ransomware disable Safe Mode making its removal complicated. For this step, you require access to another computer.

To regain control of the files encrypted by NEMTY 2.2 REVENGE, you can also try using a program called Shadow Explorer. More information on how to use this program is available here.

To protect your computer from file encryption ransomware such as this, use reputable antivirus and anti-spyware programs. As an extra protection method, you can use programs called HitmanPro.Alert and EasySync CryptoMonitor, which artificially implant group policy objects into the registry to block rogue programs such as NEMTY 2.2 REVENGE ransomware.

Note that Windows 10 Fall Creators Update includes a "Controlled Folder Access" feature that blocks ransomware attempts to encrypt your files. By default, this feature automatically protects files stored in the Documents, Pictures, Videos, Music, Favorites, and Desktop folders.

Controll Folder Access

Windows 10 users should install this update to protect their data from ransomware attacks. Here is more information on how to get this update and add an additional protection layer from ransomware infections.
