Moss Virus (.moss File)

Moss virus has deemed all your files unopenable and has locked them? See how you can remove Moss virus by following instructions provided at the bottom of this article.

Moss Virus

Moss Virus is created with the malicious aim of infecting computers and encrypting their files. The virus belongs to the so-called STOP family of viruses and this current variant does the same as previous ones. Files get encrypted so the user has no access to them. If your PC is locked and you are a victim to this virus infection, you probably have realized that after encryption was completed. System files are usually left alone so that the Operating System can function. The reason is for a ransom message to keep appearing. Moss Ransomware is a modern cryptovirus. Decryption for newly-existing STOP variants is hard to be accomplished, even when malware researchers are on the case of examining the code of the virus. If they cannot find flaws in the code of the virus, it cannot be decrypted. It could take months or even more time until said researchers figure out how to bypass the defense of the virus.

What Does Moss Ransomware Do?

Moss ransomware searches for files to lock by using a military-grade encryption algorithm. Infected computers could be sluggish during encryption. The virus places a file with a ransom message that links to a page for payment. Moss virus is also named .Moss file virus. Infected files will have the .Moss extension.

.Moss File Extension

The cybercriminals behind this STOP virus, want a large sum of money in exchange for allegedly recovering all encrypted files. .Moss virus file could create working registry entries for persistence and start with each launch of the Windows OS. Processes might also get altered in a way the hackers want. Locked files will get the .Moss extension and become encrypted. Documents, banking details, audio and video files and even archives could become encrypted.

Moss Ransomware – In-Depth Information

Moss Files Virus uses different methods for its initial infection. The payload of the virus could be put across websites for free downloads and torrents. In case something is offered as free online, you should know that it might have a malicious script inside. STOP ransomware has also been hidden in such a way. Cheats for games, hacks, cracks, rogue software usually have malware.

Moss virus is the last STOP ransomware version. If it has infected your computer you should remove it quickly. Your PC can be the source of infection for more users. Reinstallation of the Operating System does not guarantee to fully remove the virus.

.Moss files virus encrypts files and alters their code. A message with ransom instructions is placed inside folders with encrypted files. Inside the instructions you will read that the malware actors want money from you claiming that when they receive payment all your files will get restored. Without a guarantee, you do not know if after payment, you will get your files recovered. Free decryption software is released by malware researchers but could be incapapble of decrypting new versions. Researchers warn that to have successful decryption you have to be lucky and have an OFFLINE key (stored locally on the machine). In case your files are locked with an ONLINE key (stored online), the decrypter cannot find it to unlock files.
Moss files ransomware can modify entries of the Windows Registry and system processes.

The .Moss files virus will place a ransom note called _readme.txt with this text:
