The cybercriminals will buttress the fact that the victim’s entire files are now encrypted, inclusive of documents, pictures and all other personal data that are important to them. That considering the strong encryption key they was used, the victim has no other option than to pay a ransom so they could decrypt the files for them. The ransom note will also contain two email addresses: manager@mailtemp.ch and helprestoremanager@airmail.cc, for the victim to discuss further with them.   They will also inform the victim about certain conditions attached to the payment. If they’re able to make the payment within 72 hours/3 days of being notified, it will enable them to receive 50% ransom slash. In essence, instead of paying the full ransom fee of $980, they will pay $490. But once 3 days elapses, the victim will be made to pay the maximum fee. In addition to that, the victim will be instructed to pay the cryptocurrency equivalent of the USD ransom fee into a wallet address they will provide. They chose this payment option to cover their tracks so that law enforcement agencies won’t trail them. As a way of proving their capability to retrieve the encrypted files, they may request for parts of the files to be sent to them for test decryption but will also emphasize that such sample must not contain any data that could be considered as vital to the victim. Our team of cybersecurity experts’ advice as regards to ransom payments is very similar to that of the FBI, and both of them recommend that paying the ransom should never be an option, based on the following reasons:

There is no guarantee that you will retrieve your encrypted files, even after paying the ransomWhen you pay the ransom, you’re encouraging cybercriminals to continue spreading malware since it is profitable to themMore funds at their disposal will enable them to hire more developers and also pay for more hosting sites for their online torrent librariesInstead of the promised decryption tool, they may end up giving you data-stealing Trojans like VIDAR or AZORULT and use it to steal vital information such as software login passwords, banking details, cryptocurrency wallets, and other passwords saved in the browser etc. 

Victims of this STOP/DJVU variant should endeavor to remove YQAL ransomware virus from their compromised computer as soon as possible. They can do this by making use of any strong and genuine antivirus while their computer is set in the Safe Mode with Networking option. This will enable the antivirus to do a thorough job of ensuring that every trace of the malware is detected and removed. For this purpose, we recommend getting INTEGO Antivirus. Additionally, we swear by this virus damage (on Windows OS) repair tool which you can download here – RESTORO.

Ransomware Summary

REPAIR VIRUS DAMAGE

Ransomware distribution techniques you need to know about

The most prolific way through which STOP/DJVU ransomware variants, including the new YQAL virus are spread is by downloading of malicious torrents. Cybercriminals usually hide the malware in fake software contents such as pirated software copies, fake “crack” or key generators. When individuals try to make use of them, they unintentionally trigger a ransomware attack. Over the years, victims of malware attacks over the years have reported that cybercriminals often used popular software brands as a decoy in setting trap for their victims. Some of these ransomware laden contents cybercriminals upload to online torrent libraries include the following: 

Tenorshare 4ukeyAdobe PhotoshopFifa 20AutoCadOpera browserCorel DrawVMware WorkstationCubaseAdobe IllustratorLeague of LegendsInternet Download ManagerKMSPico.

Trying to download any content from online software torrents is a dangerous thing to do because you’re exposing your computer system to possible cyberattacks. They may appear attractive on the face value since you’re getting them at ridiculously low rates, but experiences have shown that they’re not worth it, considering the outrageous ransom fees you will be asked to pay when you eventually become a victim. Also remember that such activity is considered a criminal offense and liable to be prosecuted by the original content owners or their representatives. Therefore, it is in your best interest to obtain copyright contents legitimately.  Aside online malicious torrents, another major way cybercriminals spread malware is through email attachments. In this case, they make use of DOCX, PDF or XLS among others that enable macro functions/JavaScript, to compose believable messages while disguising it as originating from friends, family or famous brands. They also tend to use terms that elicit curiosity such as Order Summary, Invoice and Tracking Details etc. to fool their target audience. Sometimes, they equally make use of email spoofing techniques to hide the originating address. In such circumstances, you’re advised to apply extreme caution. If you’re not expecting such email from anyone/company, then you may as well ignore it.  Victims of STOP/DJVU ransomware should not throw caution to the wind because their computer system is already compromised and resort to desperate measures. On the contrary, you should be careful and avoid dubious websites that claim to have decryption tools. Such STOP/DJVU decryptors hardly exist and cybercriminals often use them as decoy to distribute other versions of ransomware like ZORAB. 

More information about YQAL ransomware modus operandi

Victims of cyberattack often wonder about the extent of what was done to their computer system during the YQAL ransomware attack. In a nutshell, here is a brief analogy of what happens. The first thing the malware does is to launch build.exe or build2.exe as well as winupdate.exe. The latter is responsible for displaying fake Windows update prompts. Afterwards, it will make connection with https[:]//api.2ip.ua/geo.json while the outcome will be saved in geo.json file. The malware then extracts every piece of information it deems necessary, particularly: the computer’s geolocation, zip code, time zone, latitude and longitude as well as other relevant software and hardware details, and submits them to their server.  An example of geo.json file is shown below. Additionally, the virus will grab details about the computer owner’s name, operating system installed, hardware, active processes and installed software names and save them in information.txt file format. This file will be sent to the criminals’ remote server. The next thing the malware does is to profile the computer’s geolocation against their list of encryption-protected countries—Russia, Syria, Uzbekistan, Armenia, Kyrgyzstan, Ukraine, Kazachstan, Tajikistan and Belarus. It will truncate any further action once it matches with any of them, but if it doesn’t match, it then collects online encryption key from their server and matches it with the victim’s ID before saving them in bowsakkdestx.txt file and to PersonalID.txt file.  You can check the image below to see how these files look. Whenever the virus fails to extract an online ID, it will resort to the use of an offline one. The major difference between ID is that while online ID is unique for every victim, the offline one is uniform for all. You can easily detect if an offline key was used once t1 characters appear at the end of the personal ID. The good news about offline key is that there is a chance you can decrypt .yqal files. More information on this can be obtained in this guide. At this point, full data encryption commences as it scans each folder and encrypts them with Salsa20 before locking the encryption key with RSA-2048 key. While this is going on, each file will be marked with additional extensions. Here is a screenshot of _readme.txt ransom note they drop in each folder: The next thing the virus does is to delete the Volume Shadow Copies using the command prompt task as written below:   vssadmin.exe Delete Shadows /All /Quiet The malware then compiles a list of domains in the Windows HOSTS file and sticks them to the localhost IP. It does this to effectively prevent the victim from having access to those websites, thus DNS_PROBE_FINISHED_NXDOMAIN error message may appear whenever the victim tries to open them. The reason why they do this is to ensure that victims won’t get any help from forums or blogs online.

Decrypt YQAL files

Fix and open large YQAL 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. YQAL 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 YQAL files, follow the given tutorial.

Meanings of decryptor’s messages

The YQAL 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 YQAL 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 YQAL 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.
