mhcadd Virus – Details
The mhcadd stands for a ransomware-type infection. The infection comes from the Snatch ransomware family. mhcadd was elaborated specifically to encrypt all major file types. When the file is encrypted people are unable to use them. mhcadd adds the “.mhcadd” extension for each file encrypted by it. For example, the file “myphoto.jpg“, once encrypted by mhcadd, will be renamed into “myphoto.jpg.mhcadd“. As quickly as the encryption is finished, mhcadd places a special text file into every folder containing the encrypted data.The message given by mhcadd text file asking for the ransom is definitely the like the statements given by other ransomware virus representatives belonging to the Snatch clan. It literally points out that the information is encrypted which the only way to bring back it is to use a a distinct decryption key. Sadly, this is absolutely true. The sort of cryptography mechanism used by mhcadd is still not properly examined. Still, it is absolutely particular that each victim might be given the specific decryption key, which is completely unique. It is impossible to restore the files without the key available.
Another trick of mhcadd is that the victims cannot get to the key. The key is stored on a particular server run by the frauds associated with mhcadd ransomware. To get the key and recover the important information people need to pay the ransom.
mhcadd 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.
