.666 (njkwe RaaS) ransomware (Virus Removal Instructions) - Bonus: Decryption Steps

.666 (njkwe RaaS) virus Removal Guide

What is .666 (njkwe RaaS) ransomware?

.666 (njkwe RaaS) is a file-encoder that can be purchased on various underground forums as Ransomware-as-a-service

njkwe RaaS ransomware.666 (njkwe RaaS) is the name of a ransomware that belongs to the Paradise virus family

.666 (njkwe RaaS) is the name of a Paradise ransomware variant, which has resurfaced in the midsummer of 2020. The virus takes advantage of the army-grade algorithm RSA-2048 or RSA-1024 to lock the files detected on the infected system. As a consequence, data, such as pictures, photos, Microsoft Office documents, music, videos, etc. become unusable and owners cannot even tell what is in certain documents. All of the corrupted files feature the identical logo and .666 file extension.

The original version of the .666 (njkwe RaaS) ransomware used to append .paradise, .sell, .ransom, .logger, and other file extensions. Nonetheless, this latest variant distinguishes from the others by the .666 file name, nooode.txt ransom note, and new criminal contacts – decryptdocs@msgsafe.io or decryptdocs@firemail.cc.

The .666 file virus is one of few ransomware viruses that can be purchased by wanna-be hackers on the underground forum and with the slight customization become a new Paradise ransomware strain. The so-called Ransomware-as-a-service[1] (RaaS) reduces the need to code malware and creates the group of affiliates that spin the ransomware circle. Therefore, we recommend people to take precautionary measures to protect PCs and laptops from ransomware attacks. Avoid downloading pirated software or opening spam email attachments as they may carry payload-dropper file VgvdhF8ESVZDurYTgkA.exe.

Virus damage To gain persistence the virus alters various Windows OS settings. It is capable of disabling certain processes, creating new registry keys, or deactivating programs. Thus, right after ransomware removal, experts recommend recovering the system using FortectIntego tool

The njkwe ransomware is a cyber threat that focuses on file encryption process and money extortion. Therefore, it initiates various background processes to become persistent and successfully launch the encryption software. In case of success, it locks all personal files, and each document, photo, picture, video, or file archive becomes inaccessible.

Encrypted files can be easily distinguished as each of them get the .666 file name. There's no way to open, rename, or move the locked files because they are locked using a strong encryption code, which can be cracked only using a unique decryption key that is stored by criminals.

The decryption key for every victim is unique. A person who is suffering from .666 (njkwe RaaS) virus attack is supposed to email decryptdocs@msgsafe.io or decryptdocs@firemail.cc. The message necessarily has to contain a unique ID number, which is provided on the nooode.txt ransom note. The ID typically consists of six randomly selected characters (e.g. 5xgtHk).

Criminals do not disclose how much money they are expecting to get. The note does not specify the size of the ransom but based on the previous Paradise ransomware variants it's very likely that criminals expect to get a ransom not lesser than $500 in Bitcoins. No matter what size of the redemption is, do not support criminals. Remove .666 (njkwe RaaS) virus from the system and try alternative data recovery methods instead.

.666 file virus removal requires the usage of a professional AV engine. If you have one installed, update it and run a scan while the system is rebooted into Safe Mode with Networking. The software should inform you about suchlike detection:

  • Win32:RansomX-gen [Ransom] (AVG)
  • Gen:Variant.Kazy.23813 (BitDefender)
  • A Variant Of Win32/Filecoder.Paradise.C (ESET-NOD32)
  • HEUR:Trojan-Ransom.Win32.Gen.vho (Kaspersky)
  • Ransom_Gen.R002C0WGE20 (Trend Micro)

Obfuscated files appended to email spam attachments run the payload droppers

Ransomware is one of the most dangerous cyber threats. Not only because it causes significant losses, but also because it spreads in the most stealthy manner and manages to get inside thousands of machines. Usually, hackers rely on techniques like exploits, brute-force attacks, remote code execution via unprotected RDPs, and similar. In fact, these methods most successfully work for the attacks on businesses and corporations.

The majority of home users' PCs are infected via spam. Professionally-looking emails are often sent to unsuspecting PC users who fall for opening the PDF, Word, Excel, and other forms of attachments believing that these are some kind of forms, order confirmations, or financial information.

The malicious attachments are macro-filled documents[3], so clicking on them activates the ransomware payload, which extracts the malicious executables and activates the ransomware. Once activated, there's no way to deactivate the payload unless you immediately understand that a virus entered the machine and reboot it into Safe Mode. At that time, a full scan might save the day. Anyway, to prevent this from happening, render a powerful spam filter, use a professional AV engine, and be cautious when web browsing because suspicious content can cause damage to the system.

Learn how to remove .666 (njkwe RaaS) file-encrypting virus easily

Njkwe RaaS virus removal is one-sided. There's no other way to get rid of it except run a full system scan with trusted anti-virus software. Ransomware is not a single file or installer. It's a composition of malicious processes, files, registry entries, processes, and others. Therefore, to stop all malicious performance that a cyber infection is capable of initiating, it's imminent to reboot the machine into Safe Mode and then set an anti-virus scanner to perform a full check.

There are many AV programs to choose, though we recommend using SpyHunter 5Combo Cleaner or Malwarebytes tools as both of them are powerful enough to quarantine and delete .666 virus files. The scan process can take some time, so be patient and let the application perform its task.

Upon a full Njkwe virus removal, run a scan with FortectIntego repair tool. Unfortunately, this program won't recover the .666 files. However, it will check the system for virus damage and perform a repair procedure to ensure a smooth PC's performance. The elimination of a virus is not the same as file recovery. Ransomware encrypted files are difficult to restore without working decryption software. Nevertheless, at least some of the files can be restored by running a scan with data Recovery Pro, exporting Volume Shadow Copies, or enabling previous file versions.

  • Right-click on the folder you want to restore and select “Export”. You can also select where you want it to be stored.

No official decryptor available.

Finally, you should always think about the protection of crypto-ransomwares. In order to protect your computer from .666 (njkwe RaaS) and other ransomwares, use a reputable anti-spyware, such as FortectIntego, SpyHunter 5Combo Cleaner or Malwarebytes

How to prevent from getting ransomware

Choose a proper web browser and improve your safety with a VPN tool

Online spying has got momentum in recent years and people are getting more and more interested in how to protect their privacy online. One of the basic means to add a layer of security – choose the most private and secure web browser. Although web browsers can't grant full privacy protection and security, some of them are much better at sandboxing, HTTPS upgrading, active content blocking, tracking blocking, phishing protection, and similar privacy-oriented features. However, if you want true anonymity, we suggest you employ a powerful Private Internet Access VPN – it can encrypt all the traffic that comes and goes out of your computer, preventing tracking completely.


Lost your files? Use data recovery software

While some files located on any computer are replaceable or useless, others can be extremely valuable. Family photos, work documents, school projects – these are types of files that we don't want to lose. Unfortunately, there are many ways how unexpected data loss can occur: power cuts, Blue Screen of Death errors, hardware failures, crypto-malware attack, or even accidental deletion.

To ensure that all the files remain intact, you should prepare regular data backups. You can choose cloud-based or physical copies you could restore from later in case of a disaster. If your backups were lost as well or you never bothered to prepare any, Data Recovery Pro can be your only hope to retrieve your invaluable files.
