By adding its own extension to all the encrypted data. For example, the file “timesheet.xls and video.mp4” will be titled as “timesheet.xls.qbaa and video.mp4.qbaa”.

When the encryption is accomplished, it will put text document (_readme.txt) inside each folder that contains the encrypted files.

The used technique for file's encryption will release a unique decryption key, it is different for each computer system.

The needed decryption key is hosted on a special server under the total control by the attackers, who have actually launched the ransomare into the internet joined by the victim id, the users are told to contact the attackers through an e-mail or by telegram to pay the ransom in the quantity of $980 and this quantity will have 50% discount rate, that mean the ransom amount falls to $490 if the victim pay for them within 72 hours.

How to Decrypt qbaa files that are encrypted By STOP/DJVU Ransomware?

STOP (Djvu) has two versions.

1. Oldest Version: ...decryption for most of these versions was previously supported by STOPDecrypter if infected with an OFFLINE KEY (and some of ONLINE KEYS), then updated to a new Emsisoft Decryptor method for these old Djvu variants...the decrypter will only decrypt your files without submitting file pairs if you have an OFFLINE KEY. For ONLINE KEY infection... I have made a tutorial in (English and Arabic languages) for victims who got their files encrypted with some old STOP/DJVU variants.

2. New Version: The newest extensions released around the end of August 2019 AFTER the criminals made changes.... OFFLINE IDs/KEYS for some newer variants have been obtained by Emsisoft and uploaded to their server. This is possible after a victim pays the ransom, receives a private key from the criminals and shares (donates) that key with the Emsisoft Team. ONLINE KEYS are UNIQUE for each victim and just like older versions, they are randomly generated in a secure manner and are impossible to decrypt without paying the ransom which is not advisable.

Run the decrypter on some of your encrypted files. It will tell you the status of those files.

If you have an OFFLINE ID and its key is loaded in Emsisoft servers you can download  Emsisoft decrypt tool to decrypt your files that are encrypted with the same type.

• In case you have ONLINE ID:

1. for videos and mp3 files, you can download disktuna, but for the video, you will need to have a video filmed with the same camera working or a video with the same settings.
2. for PDF files, you can try ilovePDF site that can fix the files partially.
3. for recover tools in general, they are not very effective with this type of infection, but if you want to try, you can use these free programs:

The important thing is that when you come to retrieve anything, you have to restore it to an external hard drive, not to the same hard drive.
