Ggyu Virus – Details
Ggyu is a malicious software application working as common ransomware. Michael Gillespie, the widely known virus researcher, first found this new name in the DJVU ransomware family.
Ggyu was developed for the sole purpose to encrypt all popular file types. Realistically, as soon as the encryption is successfully achieved, the users are not able to get access to them. Ggyu ransomware includes its own “.ggyu” to all the encrypted files. For instance, the file “price_list.xls”, once modified by Ggyu, will be entitled as “price_list.xls.ggyu”. Once the encryption is accomplished, Ggyu puts its own distinct text file (_readme.txt) into all the folders that store the encrypted files.
The alert stated by document requesting the random os extremely similar to the notifications provided by other ransomware dangers belonging to the DJVU family. The warning essentially shows that the information has been secured and the only service to get access to it is to use an unique standalone key. Regretfully, this declaration is definitely true.
The approach to secure the files utilized by Ggyu is not totally looked into. Nevertheless, there is no doubt that each computer system owner might be issued an unique decryption key, which is definitely unique. It is very hard to recuperate the data without the appropriate key in place.
“Don’t worry, you can return all your files!”, from text file message:
One more peculiarity of the Ggyu virus is that the users are not able to get access to the key. The decrypting key is hosted on an unique server under the total control by the criminals who have actually launched the Ggyu infection into the internet. In order to get the key and bring back the crucial information, the users are told to get in touch with the frauds through email or by telegram and to pay the ransom in the amount of $980.
The message likewise states that individuals must get in touch with the Ggyu authors within 72 hours upon the minute of the information encryption. The alert suggests that by doing so the people will get a 50% discount rate, therefore, the ransom amount falls to $490.
