Aabn – General Info
Aabn is a harmful software application functioning as common ransomware. Michael Gillespie, the widely known virus researcher, first discovered this new name in the DJVU ransomware family.
Aabn was developed for the sole purpose 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. Aabn virus adds its own “.aabn” to all the encrypted data. For instance, the file “price_list.xls”, once modified by Aabn, will be titled as “price_list.xls.aabn”. Once the file encryption is achieved, Aabn puts its own unique text document (_readme.txt) into all the folders that store the encrypted files.
The alert mentioned by _readme.txt requesting for the random os extremely similar to the alerts provided by other ransomware dangers coming from the DJVU family. The warning essentially indicates 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 absolutely true.
The approach to secure the files used by Aabn is not entirely looked into. Nevertheless, there is no doubt that each computer system owner might be provided an unique decryption key, which is absolutely special. It is exceptionally tough to recuperate the data without the appropriate type in location.
“Don’t worry, you can return all your files!”, from _readme.txt message:
One more peculiarity of the Aabn 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 total control by the scoundrels who have actually released the Aabn ransomware into the web. In order to obtain the key and restore the essential information, the users are informed to connect with the frauds by means of e-mail or by telegram and to pay the ransom in the quantity of $980.
The message also states that individuals should get in touch with the Aabn authors within 72 hours upon the minute of the information encryption. The alert shows that by doing so individuals will get a 50% discount, for that reason, the ransom quantity drops down to $490.
Aabn modified your data, however, it might not be the only threat on your PC. Plus, the ransomware might be concealed deep in the system. To spot and delete the hazard entirely, we recommend you to describe the assistance of GridinSoft Anti-Malware app.

No matter what the amount of the ransom is, we strongly encourage that you do not pay the ransom. There is no guarantee that these online scoundrels will keep their guarantees, so they might not care at all what the victims feel about the encryption, even when the quantity of the ransom is gotten into their accounts. Hence, paying ransom typically does not lead to a successful recovery. So, the users may simply lose their money for absolutely nothing.
Likewise, we urge you not to call the scams as they instruct. Do not transfer cash into their wallets. There are no applications that could split the Aabn ransomware or restore the information for free. For that reason, the only proper choice is to bring back the information from possible backups (if available).
