NEMTY PROJECT ransomware removal instructions

What is NEMTY PROJECT?

NEMTY PROJECT is a high-risk ransomware-type infection discovered by malware researcher, S!Ri. The purpose of this ransomware is to encrypt data stored on the system so that developers can make ransom demands by offering paid recovery of files. NEMTY PROJECT also appends each filename with the ".nemty" extension (e.g., "sample.jpg" becomes "sample.jpg.nemty"). Additionally, NEMTY PROJECT stores a text file named "NEMTY-DECRYPT.txt" in most existing folders. An updated variant of NEMTY Project ransomware appends filenames with the "._NEMTY_[random_characters]_" extension (e.g., "1.jpg" -> "1.jpg._NEMTY_huWhN62_") and creates another text file "_NEMTY_[random_characters]_-DECRYPT.txt" (e.g., "_NEMTY_huWhN62_-DECRYPT.txt") containing an identical message.

The messages state that data is encrypted and that victims must visit NEMTY PROJECT's website (located in the Tor network) to find decryption instructions. NEMTY PROJECT encrypts data using an AES-256 encryption algorithm that generates a unique decryption key individually for each victim. NEMTY PROJECT uses a number of additional encryption layers (RSA-2048 and RSA-8192) to protect the generated key (i.e., it uses 3-layer encryption). All decryption keys are stored on a remote server controlled by NEMTY PROJECT's developers. Therefore, after visiting the site, victims are presented with a ransom-demand message and encouraged to pay for decryption of their files. The sum is $1000 and payment must be submitted using the Bitcoin cryptocurrency. Even if you can afford to pay, never be tempted. Cyber criminals often ignore victims once payments are submitted. Therefore, all requests to submit payments should be ignored. Unfortunately, there are no tools capable of cracking NEMTY PROJECT encryption and restoring data free of charge - you can only restore everything from a backup.

There are dozens of ransomware-type infections virtually identical to NEMTY PROJECT. The list of examples includes Vesrato, Dragon, Grethen, Nacro, and many others. Although the developers are different, all of these infections are virtually identical. They encrypt data and make ransom demands. In most cases, the only major differences are size of ransom and type of encryption algorithm used. Unfortunately, encryptions are often performed using high-end algorithms such as RSA, AES, and others, that generate unique decryption keys. Therefore, unless the data was encrypted by ransomware that has bugs/flaws, restoring data manually (without developers' involvement) is impossible. Therefore, maintain regular backups and store them on a remote server (e.g., Cloud) or unplugged storage device, since locally stored backups are encrypted together with regular data. In fact, have multiple backup copies stored in different locations, since there is always chance that servers/storage devices can be damaged.

How did ransomware infect my computer?

The way developers proliferate NEMTY PROJECT is currently unknown, however, many ransomware infections are proliferated using spam emails, third party software download sources, fake software updaters and 'cracks', and trojans. Spam campaigns are used to send hundreds of thousands of deceptive emails that contain malicious attachments (links and/or files), and messages encouraging recipients to open them. To give the impression of legitimacy and increase the chance of tricking users, criminals present attachments as invoices, bills, receipts, or other important documents. Freeware download websites, free file hosting sites, Peer-to-Peer (P2P) networks (e.g., torrents, eMule, etc.) present malicious executables as legitimate software. In doing so, criminals trick users into manual download/installation of malware. Fake updaters and 'cracks' inject malware rather than serving any useful purpose (i.e., updating software or providing free access to paid features). Trojans are malicious lightweight applications designed to infiltrate systems to inject additional malware.

How to protect yourself from ransomware infections?

The main reasons for computer infections are poor knowledge of these threats and careless behavior. The key to safety is caution. Therefore, pay attention when browsing the Internet and downloading, installing, and updating software. Handle all email attachments with care. Files/links received from suspicious/unrecognizable email addresses should never be opened. The same applies to attachments that are irrelevant or do not concern you. Your software should be downloaded from official sources only, preferably using direct download links. Keep installed applications up-to-date, however, use only implemented functions or tools provided by the official developer. Be aware that third party downloaders, installers and updaters often include rogue applications, and thus such tools should never be used. Cracking installed applications should also not be considered, since software piracy is a cyber crime and the risk of infections is extremely high (many cracks are fake). Have a reputable anti-virus/anti-spyware suite installed and running at all times - this will detect and eliminate malware before it does any harm. If your computer is already infected with NEMTY PROJECT, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.
