NEPHILIM ransomware removal instructions
What is NEPHILIM?
The NEPHILIM ransomware was discovered by dnwls0719. Typically, software of this type is designed to encrypt victim's data (make files inaccessible), rename every encrypted file and create (and/or display) some ransom note with instructions on how to contact cyber criminals, pay a ransom and/or other details. NEPHILIM renames encrypted files by appending the ".NEPHILIM" extension to their filenames. For example, it renames a file named "1.jpg" to "1.jpg.NEPHILIM", and so forth. Instructions on how to contact cyber criminals who designed this ransomware are provided in a text file named "NEPHILIM-DECRYPT.txt".
As explained in a ransom note created by NEPHILM, this ransomware encrypts all files with military grade algorithms and the only way to recover them is to decrypt them with a software that can be purchased from NEPHILM's developers. In order to get instructions on how to purchase that software victims have to write them an email to firstname.lastname@example.org, email@example.com or firstname.lastname@example.org address. An email can contain up to two encrypted files, NEPHILM's developers offer to decrypt them for free. It is mentioned that if victims will not contact them, then their files will be leaked by uploading them to some Tor website. The biggest problem with programs like NEPHILIM is that they encrypt files with strong encryption algorithms and it is impossible (or almost impossible) to decrypt them without tools that only cyber criminals who designed ransomware have. It is common that victims do not get those tools even if they pay for them. Therefore, cyber criminals cannot be trusted. In such cases the only way to recover files without risking to lose any money is to restore them from a created backup. It is worthwhile to mention that removal of ransomware does not help to recover files (they remain encrypted), however, it prevents ransomware from causing further encryptions.

Some examples of other ransomware are Protect, Math and Sekhmet. As a rule, software of this type blocks access to files by encrypting them and creates and/or displays a ransom note (or notes). Usually two main variables are cryptographic algorithm (symmetric or asymmetric) that ransomware uses for encryption and size of a ransom. Unfortunately, in most cases files cannot be decrypted without tools that only cyber criminals behind particular ransomware can provide. It is possible to decrypt files without their tools only when ransomware has some bugs, flaws, is not fully developed. Since it does not happen often, it is recommended to always have a data backed up and keep it stored on some remote server (e.g., Cloud) or unplugged storage device.

To eliminate possible malware infections, scan your computer with legitimate antivirus software. Our security researchers recommend using Malwarebytes.
How to protect yourself from ransomware infections?
It is not safe to open files (and/or website links) attached to irrelevant emails, especially if they are sent from some unknown, suspicious addresses. Cyber criminals often disguise their emails as important, official. Either way, email contents should be opened only when there is no reason to suspect that it is not safe/could lead to installation of some malware. Third party downloaders, installers and other channels that are mentioned in the previous paragraph can be used to proliferate malware. Therefore, software (and files) should be downloaded from official, trustworthy websites and via direct links. Installed programs must be updated and/or activated properly - by using tools or functions that are designed by their official developers. Unofficial tools can be (and often are) designed to cause installation of various malware. Besides, it is not legal to activate licensed programs with unofficial tools. Computers should be regularly scanned for threats with a reputable antivirus or anti-spyware software and detected threats have to be removed as soon as possible. If your computer is already infected with NEPHILIM, we recommend running a scan with Malwarebytes for Windows to automatically eliminate this ransomware.

1. During your computer start process, press the F8 key on your keyboard multiple times until the Windows Advanced Options menu appears, and then select Safe Mode with Command Prompt from the list and press ENTER.
2. When Command Prompt mode loads, enter the following line: cd restore and press ENTER.
3. Next, type this line: rstrui.exe and press ENTER.
4. In the opened window, click "Next".
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 NEPHILIM ransomware virus infiltrating your PC).
6. In the opened window, click "Yes".
7. After restoring your computer to a previous date, download and scan your PC with recommended malware removal software to eliminate any remaining NEPHILIM 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 NEPHILIM 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.
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 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 NEPHILIM 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.
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.
HitmanPro.Alert CryptoGuard - detects encryption of files and neutralises any attempts without need for user-intervention:
Malwarebytes Anti-Ransomware Beta uses advanced proactive technology that monitors ransomware activity and terminates it immediately - before reaching users' files:
- The best way to avoid damage from ransomware infections is to maintain regular up-to-date backups. More information on online backup solutions and data recovery software Here.
