OFFWHITE ransomware removal instructions
What is OFFWHITE ransomware?
OFFWHITE is a part of a ransomware family called Nefilim, it was discovered by dnwls0719. Usually, software of this type is designed encrypt data, rename encrypted files and create and/or display a ransom note (or notes). OFFWHITE renames encrypted files by appending the ".OFFWHITE" extension to thei filenames. For instance, it changes "1.jpg" to "1.jpg.OFFWHITE", "2.jpg" to "2.jpg.OFFWHITE", and so on. It creates a ransom note, a text file named "OFFWHITE-MANUAL.txt".
As stated in the "OFFWHITE-MANUAL.txt" ransom note, OFFWHITE encrypted files with military grade algorithms and the only way to restore data is to decrypt it with a decryption key and software that can be purchased from OFFWHITE's developers. In order to get instructions on how to pay for decryption tools and other details victims have to send two encrypted files to SamanthaKirbinron@protonmail.com, DenisUfliknam@protonmail.com or RobertGorgris@protonmail.com. Victims are warned that if they will not contact them, then OFFWHITE's developers will start leaking data by posting it on a TOR website. Unfortunately, cyber criminals behind this ransomware are the only ones who have tools that can decrypt files encrypted by it. However, it is strongly recommended not trust and pay any cyber criminals, there is always a high possibility that they will not send decryption tool and/or key even after a payment. Possible further data loss can be prevented by uninstalling ransomware from a computer. However, it all files remain encrypted even victims uninstall ransomware. Usually, the only way to recover lost files for free (without risking to get scammed) is to restore them from a backup.

Some more examples of malicious programs like OFFWHITE are xHIlEgqxx, ZorgoCry and Paymen45. In most cases they are designed to encrypt files and keep them inaccessible until victims pay a ransom. Usually, the only two (and main) differences are price of a decryption tool or/and key and cryptographic algorithm (symmetric or asymmetric) that ransomware uses to encrypt victim's data. Most of the times it is impossible to decrypt files without the right tools that only cyber criminals behind a particular ransomware have. It is possible only when ransomware is not fully developed, has bugs, flaws. Unluckily, it happens quite rarely. Therefore, it is recommended to have data backed up and store it on a remote server (like 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 recommended not to open attachments (and/or web links) that are included in irrelevant emails. Especially if those emails are sent from unknown, suspicious addresses. Installed software must be updated and activated (if necessary) only through implemented functions and/or tools that are designed by official developers. Third party, unofficial activators, updaters often are designed to install malware. Also, it is not legal to activate licensed programs with various unofficial ('cracking') tools. Furthermore, files and programs should be downloaded from official, trustworthy websites, and via direct links. Other channels (like Peer-to-Peer networks, unofficial pages, third party downloaders, installers) can be used to proliferate malicious programs. Operating systems should be regularly scanned for threats with a reputable antivirus or anti-spyware suite and all detected threats removed right away. It is important to keep computer security software up to date. If your computer is already infected with OFFWHITE, we recommend running a scan with Malwarebytes for Windows to automatically eliminate this ransomware.

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 OFFWHITE 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 OFFWHITE 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 OFFWHITE 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.
