Hajd – General Info
Hajd is a harmful software functioning as typical ransomware. Michael Gillespie, the popular virus researcher, first found this new name in the DJVU ransomware family.
Hajd was created for the sole purpose to encrypt all popular file types. Rationally, as soon as the encryption is effectively achieved, the users are not able to get access to them. Hajd ransomware adds its own “.hajd” to all the encrypted files. For instance, the file “price_list.xls”, when modified by Hajd, will be titled as “price_list.xls.hajd”. As soon as the encryption is achieved, Hajd puts its own special text file (_readme.txt) into all the folders that save the encrypted files.
The alert stated by _readme.txt requesting for the random os very comparable to the notices given by other ransomware risks belonging to the DJVU family. The warning generally shows that the files have been encrypted and the only option to get access to it is to use an unique standalone key. Regretfully, this statement is absolutely true.
The technique to secure the files utilized by Hajd is not completely looked into. However, there is no doubt that each computer system owner may be provided an unique decryption key, which is definitely special. It is incredibly difficult to recover the data without the proper key in place.
“Don’t worry, you can return all your files!”, from text file message:
One more peculiarity of the Hajd infection 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 criminals who have launched the Hajd ransomware into the web. In order to acquire the key and bring back the crucial information, the users are told to get in touch with the frauds via email or by telegram and to pay the ransom in the amount of $980.
