The cybercriminals will emphasize that KKIA ransomware virus was able to encrypt all files contained in the infected computer, including pictures, documents and various data that may be of critical importance to the victim. Also, by virtue of the very strong and unique key used in the process, the victim would have no way out except to pay certain fees as ransom for them to decrypt the files. To that effect, two email addresses (support@sysmail.ch and supportsys@airmail.cc) will also be provided to facilitate further discussion between both parties. Decryption service prices will also be included in the ransom note as well as conditions attached with the payment. The cybercriminals will inform the victim that paying ASAP would enable them to pay only 50%. In other words, if they could pay within 72 hours of being notified, the ransom fee would be brought down to $490 but failure to meet up within that timeframe would mean paying the full ransom fee of $980. If the victim decides to contact them through any of the emails they dropped in the ransom note, they will state that payment can only be made with cryptocurrency whereby the victim will buy its equivalence and transfer same to a wallet address that would be provided by them. The apparent reason why only this method of payment is acceptable to them is to cover their tracks and remain untraceable. To assure the victim of their expertise, they may ask the victim to send parts of the encrypted file to them for test decryption, but will also add that such parts must not contain any information they could perceive as important. Nevertheless, our cybersecurity experts recommend that victims should follow FBI’s guidelines in matters relating to ransom demand/payment, and it clearly warns that ransom should not be paid. There are several reasons why ransom payment is strongly discouraged but the major ones are listed below:

Paying ransom does not guarantee you will get your encrypted files back to normal.When you pay ransom, you’re making ransomware attack profitable for them which would only perpetuate the circle.More funds at their disposal will enable them to expand their criminal activities.

Moreover, the virus is known for dropping other Trojans (AZORULT, VIDAR etc.) that could discreetly steal secretly kept information such as banking details, software login credentials, cryptocurrency wallets, passwords etc. from the compromised computer. Such loss of sensitive information to cybercriminals could lead to further problems like blackmails and theft among others. Victims of this STOP/DJVU ransomware version are advised to remove KKIA ransomware virus from their infected computer as quickly as possible. The most effective way to do so is set up the computer in Safe Mode with Networking booting process before applying any strong and up-to-date antivirus on it. The importance of using only genuine antivirus software can never be overemphasized because it could make or mar the entire process. Therefore, we recommend the use of INTEGO Antivirus because it has been tested and trusted. You should also consider downloading RESTORO which you can use to repair damages on your Windows OS files.

Ransomware Summary

REPAIR VIRUS DAMAGE

Ransomware distribution techniques in detail: avoid getting infected

The most typical ransomware proliferation method used by digital criminals behind STOP/DJVU including the likes of KKIA virus is through malicious online torrents whereby they would upload pirated software copies embedded with malware to such platforms. Some of them include the so-called “cracks” and key generators, and when unsuspecting users download them to their PC, they end up infecting them with virus. Over the years, victims of ransomware have complained about such attacks after they downloaded certain pirated software contents from various online torrent libraries as listed below:

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

For those that usually go through online torrents platforms looking for software contents to download illegally, it would be in best interest to desist from such activities. Such places are a haven for cybercriminals looking for unsuspecting computer users to prey on. Those pirated software copies embedded with malware are used as a bait to catch their victims unawares. Also remember that such illegal downloads are considered acts of copyright infringement and is punishable by law. Instead of exposing yourself to all these, we suggest that legitimate and genuine software developers should be encouraged by obtaining their works through the right channels as endorsed by them. Whatever fee they may request for their products is relatively small and can never be compared to the outrageous ransom fee demanded by cybercriminals. Another advantage is that you won’t be at risk of losing your important and sensitive files. Another ransomware distribution method used by cybercriminals is through malicious email attachments. In this option, they would compose extremely believable messages that would be accompanied with custom-made attachments crafted using platforms like XLS, PDF and DOCX. These platforms are their preferred choice because they allow JavaScript and Macro Functions, both of which can be used in conveying payload from external sources and also releasing them on other computers. Finally, STOP/DJVU ransomware victims are advised to shun certain suspicious websites that often advertise about decryption solutions because such hardly exist. At the moment only DiskTuna and Emsisoft have proven capabilities of repairing files affected by STOP/DJVU ransomware virus. You can follow this link for an explanation about them.

More information about the virus

This section deals with the technical aspect of KKIA ransomware and how it affects the computer. Firstly, the malware will set up build.exe or build2.exe as well as winupdate.exe the prompt that displays fake update screen on Windows. Once it is done with that, it will connect to https[:]//api.2ip.ua/geo.json and also save the outcome in geo.json file. This file contains every relevant detail concerning the computer geolocation, such as: time zone, country, city, zip code, longitude and latitude, and others. Examples of the geo.json file are shown in the screenshot below. The virus also drops information.txt file which contains computer’s hardware specifics, active processes and installed programs’ names. At this stage, the malware will profile the computer’s geolocation against a list of countries they designated as encryption-protected and they include: Russia, Syria, Armenia, Ukraine, Tajikistan, Kazachstan, Kyrgyzstan, Uzbekistan and Belarus. If it detects that the computer under attack is located in any of the above countries, the ransomware will immediately halt any further action. However, if on the other hand it reads negative, the ransomware will now fetch online encryption key from their server and would merge it with the victim’s ID and would save them in the bowsakkdestx.txt file and also the ID separately to the PersonalID.txt file. Examples of these files are shown below. Peradventure it fails to extract any online encryption key from their server; it will resort to the use of hardcoded offline key as an alternative. The major difference both keys is that online key is specific to each victim while offline key is the same for all victims of the same variant. The presence of t1 characters suffixed at the end of the victim’s ID is an indication that offline key was used and it increases the possibility of decrypting .kkia files someday. More information about it is provided below. The ransomware will at this point commence data encryption by scanning every folder and encrypting each file with Salsa20 algorithm. Afterwards, it will lock the encryption key using RSA-2048 code. Each file will be marked with additional extension. You can see how an affected data folder appears down below. Here is an image of _readme.txt ransom note that is usually dropped in all the folders. The malware will blacklist some specific domains by adding them to the Windows HOSTS file and any attempt by the victim to browse such domains will only bring up DNS_PROBE_FINISHED_NXDOMAIN error message. The aim of doing this is to preempt any attempt by the victim to seek help online.

Decrypt KKIA files

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

Meanings of decryptor’s messages

The KKIA 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 KKIA 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 KKIA 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.
