How to Decrypt qqjj files?

Restoring solution for big “.qqjj media files“

Try to remove .qqjj extension from some BIG files then open them. this method depends on qqjj virus ability of reading and encrypting the file, so it willnot add the filemarker. incase each file is larger than 2GB. Please, leave a comment if that will work for you.

The criminals made changes in virus coding after August 2019 for the new generated extensions. This includes Qqmt, Qqlo, qqlc, etc.

As a result of these changes, the old STOPDecrypter is no longer supported. It has been replaced with the Emsisoft Decryptor for STOP Djvu Ransomware developed by Emsisoft and Michael Gillespie.

You can download free decryption tool: Decryptor for STOP Djvu.

• Download and run decryption tool.

Start downloading the decryption tool.

Make sure to launch the decryption utility as an administrator. then click on the “Yes” button to agree with the license terms that will come up:

After accepting the license terms, the main decryptor user interface comes up:

• Select the encrypted folders.

Based on the default settings, the decryptor will automatically populate the available locations in order to decrypt the currently available drives (the connected ones), including the network drives. Extra (optional) locations can be selected with the help of the “Add” button.

Decryptors normally suggest several options considering the specific malware family. The current possible options are presented in the Options tab and can be activated or deactivated there. You may locate a detailed list of the currently active Options below.

• Press the “Decrypt” button.

As soon as you add all the desired locations for decryption into the list, click on the “Decrypt” button in order to initiate the decryption procedure.

Note that the main screen may turn you to a status view, letting you know of the active process and the decryption statistics of your data:

The decryptor will notify you as soon as the decryption procedure is completed. If you need the report for your personal papers, you can save it by choosing the “Save log” button. Note that it is also possible to copy it directly to your clipboard and to paste it into emails or messages here if you need to do so.

The Emsisoft Decryptor might display different messages after a failed attempt to restore your qqjj files:

• Error: Unable to decrypt file with ID: [your ID]

There is no corresponding decryption key in the Emsisoft decryptor’s database.

• No key for New Variant online ID: [your ID]

Notice: this ID appears to be an online ID, decryption is impossible

Your original files were encrypted with an online key. So no one else has the same encryption/decryption key pair. Recovery of qqjj files without paying the criminals is impossible. 

• Result: No key for new variant offline ID: [example ID]

This ID appears be an offline ID. Decryption may be possible in the future.

An offline key was used, but files could not be restored (the offline decryption key isn’t available yet). But, receiving this message is good news for you, because it might be possible to restore your qqjj files in the future.
It can take a few weeks or months until the decryption key gets found and uploaded to the decryptor. Please follow updates regarding the decryptable DJVU versions here.

• Remote name could not be resolved

It’s an indication of a DNS issue on your PC. Our first recommendation is to reset your HOSTS file back to default.

I'm following your method but.....

How to Solve qqjj can't be decrypted?

You will find while decrypting this result:

Error: No key for qqjj offline ID: *******

Notice: this ID appears be an offline ID, decryption MAY be possible in the future.

If your encrypted files have an OFFLINE ID and its key is loaded in Emsisoft servers, then you can use the free tool to decrypt qqjj files that have been encrypted.

qqjj ONLINE IDs for new STOP Ransomware are not supported by the Emsisoft Decrypt tool. If infected with an ONLINE ID, this free tool will indicate there is "no key" for this variant under the Results Tab and note it is impossible to decrypt.

Error: No key for New Variant online ID ***************************

Notice: this ID appears to be an online ID. decryption is impossible.

Emsisoft cannot help decrypt files encrypted with the qqjj ONLINE KEY due to the type of encryption used by the criminals.

Decryption of .qqjj Ransomware extension is impossible if infected by an ONLINE KEY without paying the criminals for that victim’s specific private key...these keys are unique for each victim in a secure manner. Without the master private RSA key that can be used to decrypt your files, decryption is impossible...the key cannot be brute-force and there is no way to gain access to the criminal's command server and retrieve this KEY.

That means: for now, the only other alternative to paying the qqjj ransom, is to backup/save your encrypted data as is and wait for a possible future solution if encrypted by an ONLINE KEY.

No one can change the encryption from online to offline, just incase you could decrypt qqjj online encryption and reencrpted with offline key again.

In case your files ONLINE encrypted with ONLINE ID: There is no free solution for New STOP djvu Ransomware online encryption.

If your qqjj files don't have important data format your hard drive and re-install a clean copy of windows, just save your encrypted data to an external storage.
