The tool was created by the malware researcher Michael Gillespie and can be downloaded from the following link, wrapped inside a .zip archive: Decryption Tool. Note that it is preferred that you download the anti-malware tool mentioned above, to make sure the ransomware does not encrypt your files again after decryption.

Mr403Forbidden Ransomware – Distribution

Mr403Forbidden ransomware could distribute its infection via various methods. A payload dropper which initiates the malicious script for this ransomware is being spread around the World Wide Web, and researchers have gotten their hands on a malware sample. If that file lands on your computer system and you somehow execute it – your computer will become infected. You can see the detections of such a file on the VirusTotal service down below:

Mr403Forbidden ransomware might also distribute its payload file on social media sites and services for file-sharing. Freeware which is found on the Web can be presented as helpful. Also, it could be hiding the malicious script for this cryptovirus. Don’t be opening files right after you have downloaded them.

Mr403Forbidden Virus – Description

Mr403Forbidden is a virus that could encrypt your files and extort you to pay a ransom to get them back to their original state. Malware researchers have discovered multiple malware samples and noted that the virus is written in Visual Studio 2010.

Mr403Forbidden ransomware might make entries in the Windows Registry to achieve persistence, and could launch or repress processes in a Windows environment. Such entries are typically designed in a way to launch the virus automatically with each start of the Windows operating system.

The ransom note message that is placed in your computer after encryption can be seen in the below screenshot:

That ransom note reads the following:

File Anda Terkunci!!!
Your Computer files is encrypted
all files with extremely
powerfull new ./Mr403Forbidden encryption
that no one can break except you have
a private string and IVs
To decrypt all file please pay us a money contact me :

_________________
Decrypt

The note of the Mr403Forbidden ransomware states that your files are encrypted. A ransom with an unspecified sum of money is demanded as payment for allegedly unlocking your files. The criminal has asked victims to send money by contacting one of the following e-mail addresses:

In case you don’t enter the correct code for decryption, the error notification shown on the right will be displayerd on your screen.

You should NOT under any circumstances pay any ransom. Your files may not get restored, and nobody could give you a guarantee for that. Furthermore, giving money to cybercriminals will likely motivate them to create more ransomware viruses or do other criminal acts.

Mr403Forbidden Ransomware – Encryption

The Mr403Forbidden cryptovirus encrypts various files and the list with file extensions which it seeks in order to encrypt files is inconclusive at this time.

Every single file that gets encrypted will receive an extension appended to it, either .alosia or Encrypting By ./Mr403Forbidden. There is even a possibility for both extensions to be present on one computer machine on different files. The encryption algorithm is unknown for the time being.

The Mr403Forbidden cryptovirus could be set to erase all the Shadow Volume Copies from the Windows operating system with the help of the following command:

→vssadmin.exe delete shadows /all /Quiet

In case the command stated above is executed that would make the encryption process more efficient as it will eliminate one of the ways for restoring your data. If your computer device was infected with this ransomware and your files are locked, read on through to find out how you could potentially restore your files.
