If your PC does not have an anti-malware program installed on it, then it can be vulnerable to the likes of Roshalock Ransomware, a highly malicious program that can put your personal files in file archives protected by a password and then demand that you pay money for it.

Therefore, we suggest that you remove this program instead of paying the ransom which can vary in amount. To find out more about this ransomware, we invite you to read this whole article.

What does Roshalock Ransomware do?

Our cyber security experts have obtained a sample of Roshalock Ransomware and tested it. They found that this particular ransomware is very different from most ransomware in that it does not encrypt the files using an encryption algorithm. Instead, it puts the files in file archives and puts on a password. You have to purchase the password from this ransomware’s developers. We do not know how much they ask initially, but we have received information that says that if you fail to pay the ransom within three days, the ransom is said to increase by 0.05 BTC.

Testing has shown that this particular ransomware can affect more than 2500 file formats which means that it can lock the majority of your personal files. It puts all of the targeted files in file archives named All_Your_Documents.rar and places them in {Drive letter}:\All_Your_Documents\All_Your_Documents.rar. Once the encryption is completed, this ransomware will drop a ransom note named All Your Files in Archive! .txt which is a simple text file that contains instruction on how to pay the ransom in English, French, Spanish, Italian, and German. It says that you have to get WinRAR and TOR browser and explains how to access the payment website and purchase the password to unlock the files. Again, there is no guarantee that you will receive the password, so we are of the opinion that you ought to delete it instead.

Researchers say that this ransomware was first spotted in February 2017 and since then it has been through several iterations.

Regardless, both of them are said to be disseminated through malicious emails that trick users into opening attached files that get your PC infected with this ransomware. The infection takes place silently and, in most cases, is successful, provided that the user does not have an anti-malware program on the PC to stop it. Furthermore, we have received information that Roshalock Ransomware could be distributed as some kind of file repairing tool, but the website that distributes it is unknown and the name under which it is promoted is a mystery as well.
