QQJJ ransomware aims to lock your files, then demand a ransom
Contents
QQJJ virus belongs to ransomware category and it is also recognized to be a variant from the notorious STOP/DJVU ransomware family. After entering the target computer, it begins encrypting each file it detects during the scan of the data system, and and completes the procedure by appending a new .qqjj extension to each file name. To illustrate how this works, see this example: 1.jpg becomes 1.jpg.qqjj, 2.txt becomes 2.txt.qqjj after the attack and so on. Once maliciously modified, these files can no longer be accessed by the computer user. Furthermore, the virus drops ransom note files named _readme.txt in several data folders.
The primary aim of STOP/DJVU ransomware variants including QQJJ virus is to extort the computer user by convincing him/her to pay a ransom once the personal data is made inaccessible. Computer users typically download this threat in a form of a setup file that is supposed to install a pirated software version. Victims usually find these downloads in rogue online websites promoting software cracks and other illegal content.
The message left in the ransom note asks for a payment
The ransom note briefly explains that the malware has encrypted all of the personal data stored on the computer and that there is no way to restore the data without the help of ransomware operators. They suggest a deal – purchasing a decryption tool and key from them for a specified price. However, victims should NOT follow commands of cybercriminals, despite the threats that they make.
The note explains that the criminals want $980 as a ransom but are willing to slash the amount in half if the computer user sends them an email within 72 hours. This means the ransom amount would be lowered to $490. The note also recommends attaching one sample of encrypted file to the email and including the Personal ID (provided in the note) for victim identification. The victim is asked to send the email to one of the following email addresses provided at the very end of the ransom note: support@bestyourmail.ch, datarestorehelp@airmail.cc.
Victims report that after contacting the perpetrators they were asked to purchase cryptocurrency worth the amount specified in USD and transfer it to the attackers’ virtual wallet address. The reason behind such payment method is anonymity – FBI can hardly trace such transactions and identify the cybercriminals or their location.
Even if your files were encrypted and you feel hopeless to recover them in other way than paying the criminals, we DO NOT RECOMMEND PAYING THE RANSOM. You can read these recommendations for ransomware victims released by FBI and also take into account our arguments:
- Paying the ransom doesn’t guarantee that criminals will fullfil their part and help you to decrypt locked data;
- Cybercriminals often try to repeatedly target victims who have paid the ransom;
- Transferring funds to ransomware operators helps them to continue their operations going.
Beware of Trojans that travel alongside this ransomware strain
Our research team warns victims of this threat to scan their computers with a genuine antivirus solution as soon as possible due to possibility that additional malware was installed alongside the main payload (the ransomware). Analysis shows that STOP/DJVU variants like this one travel along with VIDAR and AZORULT Trojans, both highly dangerous and capable to steal private information such as browser-saved passwords, cookies, browsing history and more.
Therefore, to remove QQJJ ransomware virus, we recommend preparing your computer by booting it into Safe mode with Networking. The next step should be launching of a robust antivirus solution and starting a full system scan. Afterward, we recommend you to download RESTORO (official download link) and using it to identify and repair virus-damaged Windows OS files.

Ransomware distribution techniques: know what to expect
Ransomware-type computer threats can be distributed either via email (in a form of malicious attachments), via rogue websites offering a wide range of downloads (mostly pirated software and other copyright-protected content) and via fake ads promoting malicious software update installers.
The highest risk of becoming a victim of QQJJ ransomware or any other virus from the STOP/DJVU ransomware family is for those who have a tendency to search for cracked software versions to download and install. The cybercriminals upload the malicious setup files to rogue websites that promote all kinds of software and claim the user can download them via a generated link. Another way to get these files is via torrent downloads. However, as soon as the computer user launches the alleged setup, the ransomware along other malware begins attacking the unprotected computer system.
Due to malware risks, computer users should never search for software on such rogue warez sites and instead visit the official and legitimate software developers’ websites only. It is the only way to avoid malware infections and ensure that a genuine software version is installed.
Cybercriminals are also keen on promoting malware via phishing emails containing attachments. They often pretend to be someone they’re not (such as a well-known business, for example, e-commerce website or a parcel delivery company). Hiding behind a reputable entity’s name, they claim there is an invoice, order summary or parcel delivery details included in the email attachment. However, the attachment is a typical malware-injected file that contains scripts used to run malware on the victim’s computer.
To avoid opening unsolicited emails, try to ask yourself whether the email was awaited and does the sender seems to be someone you can trust. Look out for warning signs such as unfamiliar greeting line, grammar and typo mistakes, low-quality logos, suspicious attachment type and similar to avoid getting infected.
Finally, malware is often promoted via dubious ads that are designed to promote fake software update installers. These installers are modified to install a bunch of additional software (such as spyware or malware) along the promoted update. Therefore, if you suspect that you need a software update, you should check for it in legitimate websites only.

STOP/DJVU decryption tool usage guide
STOP/DJVU ransomware versions are grouped into old and new variants. QQJJ Ransomware Virus is considered the new STOP/DJVU variant, just like JYPO, KIFR, KIOP, KITZ, BOZA, BOTY, COZA (find full list here). This means full data decryption is now possible only if you have been affected by offline encryption key. To decrypt your files, you will have to download Emsisoft Decryptor for STOP DJVU, a tool created and maintained by a genius security researcher Michael Gillespie.
Note! Please do not spam the security researcher with questions whether he can recover your files encrypted with online key - it is not possible.
In order to test the tool and see if it can decrypt QQJJ files, follow the given tutorial.
- Download the decryption tool from Emsisoft.
- Click the little arrow next to your download and choose Show in Folder.
- Now, right-click the file and choose Run as Administrator. If asked, enter administrator's password.
- In UAC window, click Yes.
- Click Yes to agree to software terms in both windows.
- The tool will automatically include C:// disk as a location to decrypt. The file recovery tool will prepopulate the locations to scan, including connected data storage drives or network drives. Click Add folder if you wish to add additional locations.
In Options tab, you can choose to keep encrypted file copies. We recommend leaving this option selected, especially if you do not know if the decryption tool will work. - Click Decrypt to start restoring QQJJ files. You will see the progress in the Results tab. Here, you can see messages from the tool, such as whether the decryption procedure is successful, or you need to wait for an update.
You might also be informed that online key was used to encrypt your files. In such case, the decryption tool won't work for you, and the only way to recover your files is to use a data backup.
Meanings of decryptor's messages
The QQJJ decryption tool might display several different messages after failed attempt to restore your files. You might receive one of the following messages:
Error: Unable to decrypt file with ID: [example ID]
This message typically means that there is no corresponding decryption key in the decryptor's database.
No key for New Variant online ID: [example ID]
Notice: this ID appears to be an online ID, decryption is impossible
This message informs that your files were encrypted with online key, meaning no one else has the same encryption/decryption key pair, therefore data recovery without paying the criminals is impossible.
Result: No key for new variant offline ID: [example ID]
This ID appears to be an offline ID. Decryption may be possible in the future.
If you were informed that an offline key was used, but files could not be restored, it means that the offline decryption key isn't available yet. However, receiving this message is extremely good news, meaning that it might be possible to restore your QQJJ extension files in the future. It can take a few months until the decryption key gets found and uploaded to the decryptor. We recommend you to follow updates regarding the decryptable DJVU versions here. We strongly recommend backing up your encrypted data and waiting.
Report Internet crime to legal departments
Victims of QQJJ Ransomware Virus should report the Internet crime incident to the official government fraud and scam website according to their country:
- In the United States, go to the On Guard Online website.
- In Australia, go to the SCAMwatch website.
- In Germany, go to the Bundesamt für Sicherheit in der Informationstechnik website.
- In Ireland, go to the An Garda Síochána website.
- In New Zealand, go to the Consumer Affairs Scams website.
- In the United Kingdom, go to the Action Fraud website.
- In Canada, go to the Canadian Anti-Fraud Centre.
- In India, go to Indian National Cybercrime Reporting Portal.
- In France, go to the Agence nationale de la sécurité des systèmes d’information.
If you can't find an authority corresponding to your location on this list, we recommend using any search engine to look up "[your country name] report cyber crime". This should lead you to the right authority website. We also recommend staying away from third-party crime report services that are often paid. It costs nothing to report Internet crime to official authorities.
Another recommendation is to contact your country's or region’s federal police or communications authority.
Frequently Asked Questions
You can only open QQJJ files if you have the decryption key, or if you were affected by offline encryption type.
To figure out whether you were affected by offline encryption, please go to C:/SystemID/PersonalID.txt and see if the string inside of it ends in t1. You can also try using Emsisoft Decryptor for STOP/DJVU.
Please follow the guidances provided by the official QQJJ decryption tools and believe what they say. If they say it is impossible to decrypt, it really is so. There is no magic tool or human capable of decrypting your files hiding somewhere. Encryption is a technique created to be nearly impossible to decrypt without a special private key (held by the criminals).
We advise scanning with anti-virus, anti-malware, malware removal tools or software like RESTORO to eliminate virus damage on the system. If you do not trust using a single tool, try running one after another. However, we do not recommend keeping several security programs on a computer at once as they can interfere with each other's work.
Beware of fake QQJJ decryption tools circulating around the web. Cyber criminals are uploading them to various shady websites, also might be promoting them via suspicious Youtube videos. These programs can infect your computer even more heavily (Trojans, miners, etc.). We suggest being extremely cautious around the web. If there will be an official STOP/DJVU decryption tool available, it will be widely discussed in public media.
