Mordor ransomware removal instructions

What is Mordor?

Mordor is a ransomware-type virus discovered by MalwareHunterTeam. This malware is a based on an open source ransomware project called Hidden Tear. Cyber criminals edit Hidden Tear source code and attempt to generate revenue by providing Mordor as a RaaS (Ransomware-as-a-Service). Mordor is distributed using spam emails that contain malicious Javascript attachments designed to run the ransomware. Once infiltrated, Mordor encrypts various files and appends the ".mordor" extension to each of them. The virus then creates an HTML file ("READ_ME.html"), placing it on the desktop.

The HTML file contains a message informing victims of the encryption and encouraging them to visit a Tor website (link provided). After visiting the website, victims are encouraged to pay a ransom to restore the compromised data. The cost of decryption is 0.07~ Bitcoin (approximately, $102). As mentioned above, Mordor is based on Hidden Tear and, therefore, uses AES cryptography. Decryption of files without a unique key is impossible. Bear in mind that cyber criminals should never be trusted - these people often ignore victims, once ransom payments are submitted. There is a high probability that paying will not deliver any positive result  and you will probably be scammed. In addition, you will support cyber criminals' malicious businesses. Unfortunately, there are no tools capable of restoring files encrypted by Mordor and you can only restore your files/system from a backup.

There are dozens of ransomware-type viruses virtually identical to Mordor including Ranion, Apocalypse, and Cry9 - these are just some examples from many. All encrypt files and make ransom demands. The only noticeable differences are size of ransom (which usually fluctuates between the equivalent of $500 and $1500 in Bitcoins) and type of encryption algorithm (symmetric/asymmetric) used. Distribution methods are also identical. Cyber criminals often proliferate ransomware by employing fake software updaters, trojans, third party software download sources (peer-to-peer networks, freeware download websites, free file hosting websites, etc.), and spam emails (infectious attachments). Therefore, keep your installed applications up-to-date and use a legitimate anti-virus/anti-spyware suite. In addition, never download software from unofficial sources or open files received from suspicious email addresses. The key to computer safety is caution.

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 Mordor 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 Mordor 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 Mordor, 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 Mordor ransomware.

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