Converton ransomware removal instructions

What is Converton?

Converton is ransomware-type malware that stealthily hijacks computers and encrypts various files. This ransomware employs the AES-256 encryption algorithm with an RSA-2048 key. Thus, two keys (public and private) are generated during encryption. Converton ransomware also adds .converton, .enigma or .czvxce extension to each compromised file. Furthermore, this ransomware creates a !!!-WARNING-!!!.html file on victims' desktops. This file contains all details regarding the encryption.

The message within the !!!-WARNING-!!!.html file states that all files have been encrypted and that the victim must pay a ransom to restore them. Cyber criminals demand 1 Bitcoin (at time of research, equivalent to $413.15). Victims are informed that if the ransom is not paid within the given time frame, the size of ransom doubles. The file also contains step-by-step payment instructions - users are encouraged to install the Tor browser and visit the URL address provided, which supposedly contains further instructions. Research shows that paying the ransom will not help victims restore their compromised files - the decryption method sent to victims after paying the ransom does not work. Therefore, you should never attempt to pay any ransom. Unfortunately, there are currently no tools capable of decrypting files compromised by this ransomware. Therefore, you can only restore the files/system from a backup.

Converton decrypt instructions

There are many ransomware-type viruses similar to Converton including, for example, Locky, Rokku, Maktub, and Locker. All encrypt victims' files and demand a ransom in exchange for the decryption key/software. The main difference between them is the encryption type and size of ransom demanded. Be aware that most ransomware is proliferated using malicious email attachments, peer to peer (P2P) networks, fake software updates, and trojans. Therefore, be cautious when opening email attachments sent from unrecognized addresses and downloading files/applications from third party sources. Additionally, keep your installed software up-to-date. Using a legitimate anti-spyware or anti-virus suite is also paramount.

Converton warning message

Text presented in !!!-WARNING-!!!.html file:

Warning! What happened to you computer?

All your files on herd drives, removable media and network files were encrypted by a cryptographically strong algorithm AES-256 with encryption key RSA-2048.
The expansion of encrypted files is .Coverton
For the time the decryption of AES-256 is impossible.
What have you to do?
To receive a pair of keys for decrypting your files you have to of through the following steps:
Simple variant: click to http://Inc57humvaxpqfv3.onion.to/ and follow the instructions OR complex variant:
1. Download TOR Browser: https://www.torproject.org/download/
2. Open link it TOR Browser http://Inc57humvaxpqfv3.onion/
3. Follow the instructions.

We recommend you not to disconnect your computer from the electrical supply.
We recommend you not to disconnect your computer from the Internet.
We recommend you not to extract the encrypted electronic data carriers.

Danger!
Do not try to cheat the system, do not attempt to edit encrypted files, do not attempt to remove the program.
Such actions can easily bring to the inability to recover your files and data, so we can not help you.

The key to decrypt your files is stored on our remote server.

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.

Boot your computer in Safe Mode with Command Prompt

2. When Command Prompt mode loads, enter the following line: cd restore and press ENTER.

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 Converton 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 Converton 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 Converton 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 Converton, 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 encrypting ransomware such as this, use reputable antivirus and anti-spyware programs. As an extra protection method, you can use programs called HitmanPro.Alert and Malwarebytes Anti-Ransomware, which artificially implant group policy objects into the registry to block rogue programs such as Converton ransomware.)

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