Maktub ransomware removal instructions

What is Maktub?

Maktub is ransomware distributed via zipped Word documents. Once the file is extracted and opened, Maktub infiltrates the system and encrypts files stored on the victim's computer. Maktub ransomware adds a .NORV, .gyul (or other random) extension to each file encrypted, thus, making it straightforward to determine which files are encrypted. After encryption, Maktub opens a window containing a message stating that the files are encrypted and that user must pay a ransom to decrypt them. It is also stated that the ransom must be paid within the given time frame, otherwise encryption will become impossible.

The message states that the victim must pay the ransom within 12 hours. Be aware that the algorithm used to encrypt the files generates two keys - public and private. The private key is stored on remote servers controlled by cyber criminals. Therefore, if the ransom is not paid within the given time frame, the key will supposedly be deleted. It is impossible to decrypt the files without this key. The displayed window also contains step-by-step payment instructions. To pay, users must download the Tor browser, go to Maktub's website, and follow the further instructions. Note that Maktub developers allow victims to decrypt a number of files free of charge as an 'insurance'. Currently, the size of ransom is unknown, however, ransomware-type malware often makes demands for 0.5 - 1.5 Bitcoin ($204.55 - $613.65). Unfortunately, at time of research, there were no tools capable of decrypting files affected by Maktub. Therefore, the only and best solution to this problem, is to restore your system from a backup.

Maktub decrypt instructions

Maktub is simply another ransomware program and, therefore, shares many similarities with Teslacrypt, Locky, CryptoWall, Surprise, Vault, and many other viruses. All are designed to stealthily infiltrate the system and encrypt stored files. The main differences between these viruses are the size of ransoms demanded and types of algorithms used to encrypt the files. It is highly probable that your files will remain encrypted even if you pay the ransom. Paying is equivalent to sending your money directly to cyber criminals - you merely support their malicious business. For this reason, you should never attempt to contact cyber criminals or pay their ransoms. Ransomware is often distributed via P2P networks (for example, Torrents), malicious email attachments, fake software updates, and trojans and, therefore, you should be cautious when downloading files from untrusted sources and opening attachments sent from unrecognized emails. In addition, all installed applications should be kept up-to-date and using a legitimate anti-virus, or anti-spyware suite is paramount.

7. After restoring your computer to a previous date, download and scan your PC with recommended malware removal software to eliminate any remaining Maktub 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 Maktub 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 Maktub, you can also try using a program called Shadow Explorer. More information on how to use this program is available here.
