What happened to my files?
A strange extension "QBAA" has been added to your files, and you can't open
your files.
So, you think your files are locked ?!.
No, your files are totally encrypted by a Ransomware affect, which
generate a new extension belongs to some types of malwares.
These type of attack can lock /encrypt/ damage your files (videos,
images, documentations) and whatever you think. Then your file name will
end by a new extension, So you can’t obtain access to them at all.
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.
We highly recommend that you do not pay the ransom, There is no
warranty that these online cyber criminals will keep their promises, the victims may lose

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:
-
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.
-
for PDF files, you can try ilovePDF site that can fix the files
partially.
-
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.
