Hhjk Ransomware


There is a new ransomware that has been recently spotted by researchers. It is called simply the Hhjk ransomware and analysis shows it belongs to the Djvu family of ransomware types.

Once the ransomware executes on an infected system, it will run its encryption process. Encrypted files retain their original filenames, but their extensions are appended with ".hhjk". In this way, if a file was originally called "picture.jpg", it will turn into "picture.jpg.hhjk" once it has been encrypted.

The ransom note dropped by the Hhjk ransomware is stored inside a file called "_readme.txt". The hackers operating the malware ask for payment amounting to nearly a thousand US dollars, promising to restore files for half that amount, if they are contacted within the first 72 hours following encryption. Of course, believing the promises of cybercriminals is never a good idea.

The decryption of a single file is offered as proof that the threat actor really has a decryption tool and can restore the files on the victim's system.

The full ransom note text goes as follows:
