Ahgr – Ransomware
Ahgr is a destructive software application functioning as typical ransomware. Michael Gillespie, the popular virus researcher, very first found this new name in the DJVU ransomware family.
Ahgr was developed for the sole function to encrypt all popular file types. Logically, as soon as the encryption is successfully accomplished, the users are not able to get access to them. Ahgr virus includes its own “.ahgr” to all the encrypted data. For instance, the file “price_list.xls”, when modified by Ahgr, will be titled as “price_list.xls.ahgr”. When the encryption is accomplished, Ahgr puts its own distinct text file (_readme.txt) into all the folders that keep the encrypted files.
The alert mentioned by document asking for the random os extremely similar to the notices provided by other ransomware hazards belonging to the DJVU family. The warning essentially shows that the files have been encrypted and the only service to get access to it is to use an unique standalone key. Regretfully, this statement is absolutely real.
The approach to encrypt the files used by Ahgr is not completely looked into. However, there is no doubt that each computer owner might be provided an unique decryption key, which is definitely special. It is very tough to recuperate the information without the appropriate key in location.
“Don’t worry, you can return all your files!”, from _readme.txt message:
One more peculiarity of the Ahgr virus is that the users are unable to get access to the key. The decrypting key is hosted on an unique server under the complete control by the scoundrels who have actually released the Ahgr virus into the web. In order to acquire the key and bring back the crucial information, the users are informed to get in touch with the scams by means of email or by telegram and to pay the ransom in the amount of $980.
The message likewise says that the people ought to get in touch with the Ahgr authors within 72 hours upon the moment of the information file encryption. The alert suggests that by doing so the people will acquire a 50% discount, for that reason, the ransom quantity drops down to $490.
