The ransom note will emphasize that the entire data contained in the compromised computer has been encrypted by ZAQI ransomware virus, and they made use of a very strong encryption key. Therefore, the only way the victim could ever regain access to the files is by paying ransom. Also included in the message are two email addresses (manager@mailtemp.ch and helpsupportmanager@airmail.cc) which the victim is expected to write to in order to get in touch with the criminals. In addition to that, decryption service prices would also be provided with terms and conditions attached to it. They will notify that if the victim is able to comply within the next 72 hours i.e. 3 days, a 50% discount will be granted, which means that instead of paying a ransom fee of $980, $490 would be acceptable. However, once the 3 days grace period elapses, only the full amount is what must be paid. Once they’re contacted via email, the cybercriminals will clarify that cash payment is prohibited; instead the victim would have to pay with digital currency such as Bitcoin. They will request that the cryptocurrency worth of the ransom fee should be transferred to their own wallet address. The main reason why they chose this medium of payment is to cover their tracks and avoid any link law enforcement agencies could use to identify them. In order to bolster their confidence and motivate to pay the ransom, the cybercriminals may suggest for random files to be sent to them for test decryption but will warn that such file shouldn’t contain valuable information. Our cybersecurity experts advise that victims should follow FBI’s directive which is against the payment of ransom; therefore, the consensus recommendation is NO TO RANSOM PAYMENT! This standpoint is logical considering the following issues:

There is no guarantee you will retrieve your lost data even after paying ransom;Paying ransom is a form of indirect endorsement of criminal activities;More money in the hands of cybercriminals would enhance their capacity to commit more crimes against the public.

Criminals involved in ransomware are increasingly milking millions of dollars from their victims who inadvertently had their computer systems infected by these file-encrypting malwares. Thus it is very important reduce it drastically by putting a stop to ransom payment. In addition to that, the virus usually drops Trojans such as AZORULT and VIDAR that are notorious for their information stealing ability. They can surreptitiously steal vital personal information like Passwords, banking details, cryptocurrency wallets, and software login credentials among others. Such sensitive information in the wrong hands can lead to further problems like blackmails or theft. If you are already a victim of this variant of STOP/DJVU virus, you shouldn’t panic but it’s very important to remove ZAQI ransomware with immediate effect. You will need a strong antivirus software and also put your computer in Safe Mode with Networking option before you can effectively remove traces of the virus safely. If you’re unsure which antivirus to use, you may want to take our recommendation and try INTEGO Antivirus, which has outstanding malware detection rate. Additionally, we recommend you to download RESTORO to repair virus damage inflicted on Windows OS files.

Ransomware Summary

REPAIR VIRUS DAMAGE

Ransomware distribution methods you should be wary of

The most common method of distributing variants of STOP/DJVU ransomware, including ZAQI virus is through downloading of malicious torrents. The cybercriminals are known to hide them in pirated software contents, particularly fake “cracks” and key generators. When unsuspecting computer users make use of these illegal software copies, they inadvertently unleash malware on their computer. A cross-section of those who have fallen victim to some of these ransomware variants, generally mention diverse software names the cybercriminals often make use of. They include pirated license activation tools and deceptive “cracks” among others. These malware-laden software copies are usually uploaded to online torrent libraries as bait to lure unsuspecting victims. Listed below are some of the most popular ones:

Internet Download Manager;VMware Workstation;Tenorshare 4ukey;AutoCad;Corel Draw;Fifa 20;Cubase;Adobe Illustrator;Opera browser;League of Legends;Adobe Photoshop;KMSPico (illegal Windows activation tool).

If you’re among those that visit online software torrents, then it’s high time you put a stop to such risky activity. Cybercriminals are often waiting to prey on such freeloaders. Therefore, it is better to be safe than sorry. It doesn’t end there; illegally downloading files with copyright patents can be grounds for criminal prosecution. It is more decent and safe to encourage growth of the industry by paying the official prices and also obtaining them using legitimate platforms such as official websites of the producers or their affiliated partners only. Also take cognizance of the fact that whatever amount you’re asked to pay is insignificant compared to the insane amount of money cybercriminals will demand from you as ransom if/when you fall victim. Likewise, you won’t be putting your sensitive data at risk. Aside online torrents libraries, cybercriminals also make use of malicious email attachments in distributing ransomware. In this case, they often create highly convincing messages while also adding deceptively crafted attachments to it. The most popular platforms they use are PDF, DOCX and XLS. They prefer these ones because they enable JavaScript or macro functions, both of which are perfect for transferring and triggering payload on computers. Victims of STOP/DJVU ransomware tend to get desperate in their search for decryption solutions and they end up going to dubious sites. Please note that most of those sites claiming to offer decryption services are not genuine because such rarely exists. These fake STOP/DJVU decryptors they decoys cybercriminals also use to spread other ransomware variants such as ZORAB. They can cause double encryption of your files.

How this ransomware variant operates

You can go through this section to actually understand what actually occurred during ZAQI ransomware attack, especially the technical aspect. The first thing the malware does is to set up build.exe or build2.exe as well as winupdate.exe (this is what prompts the display of fake Windows update). The virus then connects to https[:]//api.2ip.ua/geo.json and fetches details such as geolocation, zip code, time zone, longitude and latitude. The response from the said domain will be saved into geo.json file. Additionally, the virus gather’s details such as victim’s computer name, operating system, hardware, installed software and active processes and saves them to information.txt file. The ransomware also takes a screenshot of victim’s desktop. These pieces of information will then be sent to the control server. Shown below is a screenshot of two geo.json file examples. You can see an example of information.txt file below. Using the geolocation, the malware will compare it with a group of countries that are designated as encryption exempted. The countries are Ukraine, Russia, Uzbekistan, Syria, Kazachstan, Armenia, Belarus, Tajikistan and Kyrgystan. If the geolocation indicates that it is situated in any of these countries, it will automatically abort any further action. However, if it shows otherwise, the ransomware will move to the next stage where it commences the extraction of online encryption key from their control server. This online key will be merged with the victim’s ID and the result stored in bowsakkdestx.txt file and to PersonalID.txt file. The screenshot provided below is a good example of both of these files. If on the other hand, the virus couldn’t extract an online encryption ID, it will settle for offline encryption ID as an alternative. However, unlike the online ID that is unique to each victim, the offline ID is universal for all victims thus brightening the chance of being able to decrypt .zaqi files someday. More information about this is provided in this article about repairing/decrypting files affected by STOP/DJVU versions. At this point, the ransomware will commence the full data encryption process by scanning every folder and encrypting them with Salsa20 and locking the encryption key with the RSA-2048 key. While this is still ongoing, the virus will mark each file with a file marker extension. A replica screenshot of _readme.txt ransom note that is left in all the folders is displayed in the image below. At this point, the virus will delete all Volume Shadow copies by making use of the command prompt task as shown here: vssadmin.exe Delete Shadows /All /Quiet After that, the virus would compile certain domains and forward to the Windows HOSTS file where it would be placed on the localhost IP. This will automatically prevent victims from having access to any of those deny-listed websites. When they make attempts, the DNS_PROBE_FINISHED_NXDOMAIN error message is what will appear on their screen. The reason why they block these sites is to prevent the victim from getting help online.

Decrypt ZAQI files

Fix and open large ZAQI files easily:

It is reported that STOP/DJVU ransomware versions encrypt only the beginning 150 KB of each file to ensure that the virus manages to affect all files on the system. In some cases, the malicious program might skip some files at all. That said, we recommend testing this method on several big (>1GB) files first.

STOP/DJVU decryption tool usage guide

STOP/DJVU ransomware versions are grouped into old and new variants. ZAQI Ransomware Virus is considered the new STOP/DJVU variant, just like BPTO, ISWR, ISZA, BPSM, ZOUU, MBTF, ZNSM (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 ZAQI files, follow the given tutorial.

Meanings of decryptor’s messages

The ZAQI 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 ZAQI 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.

Victims of ZAQI 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.
