Wesker Encrypter ransomware removal instructions

What is Wesker Encrypter?

Wesker Encrypter is malicious software (ransomware) that prevents victims from accessing their files by encoding them with strong encryption. Therefore, victims cannot access files unless a cryptocurrency ransom is paid. Unlike most programs of this type, Wesker Encrypter does not rename any encrypted files. It simply creates a ransom message in the "!!!INSTRUCTION_RNSMW!!!.txt" text file, which contains instructions about how to recover files.

The ransom message states that files were not damaged, but were modified and can be decrypted - victims are encouraged to download and install the Tor browser and use it to open a website link provided. The message contains a warning stating that victims should not try to reinstall the operating system or try to restore or decrypt files. The decryption tool can be purchased only by using the link provided. The website contains information about the decryption tool cost and some other details. The tool is called "Wesker Decryptor" and costs the equivalent of 0.72270001 in the Dash (cryptocurrency). After seven days, however, the cost doubles to 1.44540002 Dash. To purchase the tool, victims must click "Get Dash Address" and transfer funds with the cryptocurrency wallet address provided. Once payment is made, the website generates a download link for the decryption tool. This may seem to be an easy way to recover files, however, most cyber criminals (ransomware developers) do not keep their promises and cannot be trusted. Typically, they ignore victims once they receive the cryptocurrency payment. Unfortunately, encryptions caused by ransomware-type programs are impossible to decrypt without using tools held only by ransomware developers. Generally, the only way to regain access to files stored on the computer is to use data backup and restore everything from there.

Wesker Encrypter is one of many programs of this type. There are hundreds and the number is growing daily. SYSTEM FAILURE, DrWeb, and Bufas are examples of other ransomware-type programs similar to this one. Typically, these programs are created to encrypt data and keep it in that state until a ransom is paid. Two main differences are cost of decryption (tool/key) and cryptography algorithm that ransomware employs to encrypt files. Despite any similarities and differences, most of these programs cause encryptions that cannot be decrypted without the involvement of cyber criminals. Therefore, have a backup created and keep it stored on a remote server or unplugged storage device.

How did ransomware infect my computer?

It is unknown which method Wesker Encrypter developers use to proliferate this ransomware, however, most cyber criminals employ spam campaigns, trojans, dubious software download sources, software cracking tools and unofficial (fake) software updaters. With spam campaigns, they send countless emails with attached malicious files (or web links that lead to them). If opened, the files download and install malware. Most commonly used attachments are Microsoft Office and PDF documents, ZIP, RAR and other archives, executables (like .exe files), JavaScript files, and so on. Trojans can be used to proliferate malicious programs only if they are already installed. If installed, they proliferate ransomware and other malicious software. Malicious programs can also be distributed through untrustworthy software download channels. Some examples are freeware download websites, free file hosting sites, third party downloaders, P2P (Peer-to-Peer) networks such as eMule, and torrent clients. When people download files from these sources, they risk download of malicious files, which are disguised as harmless. When opened, they install malware. Software 'cracking' tools often install malicious programs rather than allowing users to bypass paid software activation. Fake software updaters usually cause damage by exploiting bugs/flaws of outdated software, or by downloading and installing malicious programs rather than the expected software fixes/updates.

How to protect yourself from ransomware infections?

Do not open irrelevant emails that contain attachments/web links and are sent from unknown, suspicious addresses. These emails may seem to be legitimate and important, however, this is not enough for them to be trusted. Various third party downloaders, installers, unofficial websites, Peer-to-Peer networks (and other similar sources) should not be used to download or install software. Download using official websites and direct links. Installed software should be updated, however, the only safe way to achieve this is by using tools/implemented functions provided by official software developers. Using software cracking tools is a cyber crime and, therefore, these tools should not be used to bypass paid activation. Furthermore, they can be used to proliferate viruses. Finally, have reputable anti-virus or anti-spyware software installed and enabled to prevent various threats. If your computer is already infected with Wesker Encrypter, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.

4. In the opened window, click "Next".

restore system files and settings

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 Wesker Encrypter 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 Wesker Encrypter 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 Wesker Encrypter 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 Wesker Encrypter, 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 Wesker Encrypter 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 as well as 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.

HitmanPro.Alert CryptoGuard - detects encryption of files and neutralises any attempts without need for user-intervention:
