Gcahvv Virus – Details
The Gcahvv stands for a ransomware-type infection. The infection comes from the Snatch ransomware family. Gcahvv was elaborated specifically to encrypt all major file types. As soon as the file is encrypted people are unable to use them. Gcahvv adds the “.gcahvv” extension for each file encrypted by it. For example, the file “myphoto.jpg“, once encrypted by Gcahvv, will be renamed into “myphoto.jpg.gcahvv“. As quickly as the encryption is completed, Gcahvv places a special text file into every folder containing the encrypted data.The message given by Gcahvv text file requesting for the ransom is absolutely the like the statements given by other ransomware virus representatives belonging to the Snatch family. It actually mentions that the info is encrypted which the only way to bring back it is to use a a special decryption key. Regretfully, this is definitely true. The kind of cryptography mechanism used by Gcahvv is still not appropriately examined. Still, it is absolutely particular that each victim may be given the specific decryption key, which is completely distinct. It is impossible to restore the files without the key available.
Another technique of Gcahvv is that the victims cannot gain access to the key. The key is saved on a particular server run by the frauds associated with Gcahvv ransomware. To get the key and recover the important information people need to pay the ransom.
