Adlg – General Info

Adlg is a malicious software application functioning as typical ransomware. Michael Gillespie, the well-known malware researcher, very first found this new name in the DJVU ransomware family.

Adlg was created for the sole purpose to encrypt all popular file types. Realistically, as soon as the file encryption is effectively accomplished, the users are unable to get access to them. Adlg ransomware includes its own “.adlg” to all the encrypted files. For instance, the file “price_list.xls”, when modified by Adlg, will be entitled as “price_list.xls.adlg”. When the file encryption is accomplished, Adlg puts its own unique text document (_readme.txt) into all the folders that keep the encrypted files.

The message mentioned by document requesting the random os extremely comparable to the notifications offered by other ransomware risks belonging to the DJVU family. The caution generally indicates that the data has been secured and the only solution to get access to it is to use a special standalone key. Regretfully, this declaration is absolutely true.

The method to encrypt the files used by Adlg is not totally researched. Nevertheless, there is no doubt that each computer system owner might be released an unique decryption key, which is absolutely special. It is incredibly hard to recuperate the information without the proper key in location.

The decrypting key is hosted on a special server under the complete control by the crooks who have released the Adlg virus into the web.
