RS – Ransomware
The RS stands for a ransomware-type infection. The infection comes from the MedusaLocker ransomware family. RS was elaborated particularly to encrypt all major file types. When the file is encrypted people are unable to use them. RS adds the “.RS” extension for each file encrypted by it. For example, the file “myphoto.jpg“, once encrypted by RS, will be renamed into “myphoto.jpg.RS“. As quickly as the encryption is finished, RS places a special text file into every folder containing the encrypted data.The message given by RS text file asking for the ransom is definitely the like the statements given by other ransomware virus representatives coming from the MedusaLocker clan. It actually points out that the info is encrypted which the only way to bring back it is to use a a distinct decryption key. Regretfully, this is absolutely true. The type of cryptography mechanism applied by RS is still not correctly examined. Still, it is definitely certain that each victim may be given the specific decryption key, which is absolutely unique. It is difficult to restore the files without the key available.
Another technique of RS is that the victims cannot gain access to the key. The key is kept on a specific server run by the frauds associated with RS ransomware. To get the key and recover the important information people need to pay the ransom.
RS encrypted your documents, but that might not be the only damage done to you. The ransomware might still be hidingon your computer. To identify whether this holds true, we suggest downloading GridinSoft Anti-Malware.
