Tghz is a destructive software application working as common ransomware. Michael Gillespie, the widely known virus researcher, very first found this new name in the DJVU ransomware family.
Tghz was created for the sole function to encrypt all popular file types. Rationally, as quickly as the encryption is successfully achieved, the users are unable to get access to them. Tghz virus adds its own “.tghz” to all the encrypted files. For instance, the file “price_list.xls”, when crypted by Tghz, will be titled as “price_list.xls.tghz”. Once the file encryption is achieved, Tghz puts its own unique text file (_readme.txt) into all the folders that store the encrypted files.
The alert mentioned by _readme.txt requesting for the random os really comparable to the notifications given by other ransomware hazards belonging to the DJVU family. The warning basically indicates that the files have been secured and the only service to get access to it is to use a distinct standalone key. Regretfully, this declaration is absolutely true.
The approach to encrypt the files utilized by Tghz is not totally researched. However, there is no doubt that each computer owner might be provided an unique decryption key, which is absolutely distinct. It is very difficult to recover the information without the appropriate key in place.
“Don’t worry, you can return all your files!”, from _readme.txt message:
One more peculiarity of the Tghz ransomware is that the users are not able to get access to the key. The decrypting key is hosted on an unique server under the complete control by the crooks who have actually introduced the Tghz infection into the internet. In order to acquire the key and restore the crucial information, the users are told to connect with the scams via email or by telegram and to pay the ransom in the amount of $980.
The message also states that individuals must contact the Tghz authors within 72 hours upon the minute of the data encryption. The alert indicates that by doing so individuals will get a 50% discount, therefore, the ransom quantity falls to $490.
