What is NEMTY REVENUE 3.1?

NEMTY REVENUE 3.1 is a piece of malicious software, it is a new variant of the Nemty 2.6 ransomware. Systems infected with this malware experience data encryption and receive ransom demands for the decryption tools/software. During the encryption process, all affected files are retitled according to this pattern - original filename followed by an extension consisting of "NEMTY", underscore symbol and a random character string (e.g. "NEMTY_[random_string]"). For example, a file like "1.jpg" would appear as something similar to "1.jpg.NEMTY_4FA50B7" - following encryption. Once this process is finished, a ransom note - "NEMTY_[random_string]-DECRYPT.txt" is created.

The ransom-demanding message informs victims that their data has been encrypted with the AES-128 and RSA-2048 cryptographic algorithms. The note states that the only way of recovering the compromised files is to purchase the decryption key from the cyber criminals, behind NEMTY REVENUE 3.1. Users are also warned that attempting recovery with third party decryption tools - will damage the data beyond repair. To get more information on how to pay the ransom, the message instructs victims to visit the listed websites. In many cases of ransomware infections, without the involvement of the criminals responsible - decryption is impossible. It might be, if the malicious program is still in development and/or has significant bugs (flaws). Whatever the case, it is strongly advised against communicating with and/or paying cyber criminals. Since often, despite meeting the ransom demands - users do not receive the necessary keys/tools to decrypt their data. Therefore, the files remain encrypted and worthless, and victims experience financial loss. To prevent NEMTY REVENUE 3.1 from further encryptions, it must be eliminated from the operating system. Unfortunately, removal will not restore already encrypted data. The sole solution is recovering it from a backup. Provided, if one was created prior to the infection and was stored in a separate location (so as not to have been affected by NEMTY REVENUE 3.1).

Protect (Hydra)Wanna Decrypt0r 4.0 and Sekhmet are a few examples of other ransomware. Malicious programs within this category are designed to encrypt files and demand payment for the decryption. Crucial differences between them are: the cryptographic algorithm they use (symmetric or asymmetric) and the ransom size. These payments tend to range from three to four digits (in USD). Digital currencies (e.g. cryptocurrencies, pre-paid vouchers, etc.) are usually used for the payments, due to transactions of such being difficult/impossible to trace. To protect data integrity, it is recommended to store backups in remote servers and/or unplugged storage devices (ideally, in multiple different locations).

How did ransomware infect my computer?

Malware (ransomware included) is commonly proliferated via trojans, spam campaigns, illegal activation ("cracking") tools, fake updaters and untrustworthy download channels. Trojans are malicious programs, capable of causing chain infections (i.e. download/install additional malware). Spam campaigns define operations, during which thousands of deceptive emails are sent. This mail is typically disguised as "important", "official", "urgent", "priority" and so on. The letters have infectious files attached to them or alternatively can contain download links of malicious content. Virulent files can be in variety of formats (e.g. archive and executable files, PDF and Microsoft Office documents, JavaScript, etc.); when they are opened - it initiates the infection process. "Cracking" tools can download/install malicious software, instead of activating the licensed products. Fake updaters cause infections by exploiting weaknesses of outdated products and/or by simply installing malware, rather than the promised updates. Malicious content can be unintentionally downloaded from untrustworthy sources, e.g. unofficial and free file-hosting sites, Peer-to-Peer sharing networks (BitTorrent, eMule, Gnutella, etc.) and other third party downloaders.

How to protect yourself from ransomware infections?

Dubious and/or irrelevant emails should not be opened, especially any attachments or links present in such - as that can result in a high-risk system infection. It is recommended to only use official and verified download channels. It is just as important to activate and update products with functions/tools, provided by legitimate developers. Illegal activation tools ("cracks") and third party updaters are deemed to be highly unreliable and are advised against use. To ensure device and user safety, it is paramount to have a dependable anti-virus/anti-spyware installed and kept up-to-date. This software is to be used for regular system scans and to remove detected threats/issues. If your computer is already infected with NEMTY REVENUE 3.1, we recommend running a scan with Malwarebytes for Windows to automatically eliminate this ransomware.

5. Select one of the available Restore Points and click "Next" (this will restore your computer system to an earlier time and date, prior to the NEMTY REVENUE 3.1 ransomware virus infiltrating your PC).

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 REVENUE 3.1 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 REVENUE 3.1 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 REVENUE 3.1, 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 REVENUE 3.1 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.
