Nsemad – General Info
The Nsemad stands for a ransomware-type infection. The infection comes from the Snatch ransomware family. Nsemad was elaborated specifically to encrypt all major file types. As soon as the file is encrypted people are unable to use them. Nsemad adds the “.nsemad” extension for each file encrypted by it. For example, the file “myphoto.jpg“, as soon as encrypted by Nsemad, will be renamed into “myphoto.jpg.nsemad“. As quickly as the encryption is completed, Nsemad places a special text file into every folder containing the encrypted data.The message given by Nsemad text file requesting the ransom is definitely the like the statements given by other ransomware virus representatives belonging to the Snatch clan. It literally discusses that the info is encrypted which the only way to restore it is to use a a special decryption key. Sadly, this is definitely true. The kind of cryptography mechanism applied by Nsemad is still not correctly examined. Still, it is definitely certain that each victim may be given the specific decryption key, which is totally distinct. It is difficult to restore the files without the key available.
Another technique of Nsemad is that the victims cannot gain access to the key. The key is stored on a specific server run by the frauds associated with Nsemad ransomware. To get the key and recover the important info people need to pay the ransom.
Nsemad 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.
