What is Kkia Ransomware

Kkia is another file-encryptor developed and spread by the STOP/Djvu family. It copies all traits and capabilities of older versions issues by the STOP/Djvu group. The virus encrypts PC-stored data and demands crypto ransom for unique decryption software that will decipher this data. Most often, malware like Kkia targets vital data like images, music, videos, and documents containing important information. After detecting such files, the ransomware program will generate unique ciphers and write them over the files to prevent users from accessing them. Apart from this, ransomware infections also append new extensions to highlight the encrypted data. In the case of Kkia Ransomware users will see their data changed with the .kkia extension. This means a regular file like 1.pdf will change its look to something like this 1.pdf.kkia. After this, Kkia developers create a text note called _readme.txt that explain decryption instruction. Note that all of these changes happen in a blink of an eye so it is impossible to track which part of encryption occurred first. This is what you can see written inside of the text note with ransom demands. The same ransom note template was used in previous versions as well:

According to the file content, victims are able to recover their data only by paying for special decryption software (a tool and key), which will decode unique ciphers assigned to each victim. Unfortunately, this is the only way to decrypt files unless ransomware contains some serious vulnerabilities that help third-party tools crack open the ciphers. It can be the case if ransomware failed to generate online keys due to lack of connection and was forced to create offline ones instead. To avoid the guessing game, it is safer and better to recover your files using backup copies. In all other cases, the decryption of Kkia files is almost impossible unless the aforementioned. The cost of decryption offered by cybercriminals is 980$, but it can be cut down to 490$ if victims contact developers within 72 hours after getting infected. Communication between victims and ransomware developers is guided to be established via one of the e-mail addresses (support@sysmail.ch or supportsys@airmail.cc). Additionally, Kkia developers offer the victims to send 1 file containing no valuable information to test free decryption. By doing so, ransomware developers prove their capability of decrypting your data. Unfortunately, whatever they do to uplift their trust and push victims into performing the requested steps is still not enough to be 100% sure about their trustworthiness. Just like other fraudulent figures, they are able to fool you and not send any decryption tools even after paying the ransom. If you do not have money to pay the ransom, or simply do not want to risk your money, we recommend using backup copies as mentioned above. It is also possible some victims do not have very important data encrypted, so they can afford to lose it without regrets. However, if you are the opposite case and willing to decrypt your data without having any backup copies, you can give it a try nonetheless. Along with removal instructions, we have prepared a list of the most popular and effective tools able to decrypt compromised data in some post-encryption scenarios.

How Kkia Ransomware infected your computer

Ransomware developers exploit a lot of distribution techniques to spread various infections. E-mail spam letters, trojans, fake software updaters or installers, backdoors, botnets, keyloggers, web-injects, malicious ads, and other dangerous channels are those often successful in spreading malicious software. The one to stick around the top of this list happens to be e-mail spam. It is abused by cybercriminals to send malicious attachments. MS Office files like Word or Excel, PDF, Executable, and JavaScript files are very often located in malicious letters of such type. Most often, they are sent from legitimate-looking sources like DHL, DPD, FedEx, or Financial organizations asking to open the files. In case you stumbled upon something similar, be sure this is a trap leading to malicious infections. Usually, such companies will never send you messages with requests to open or download something without a reason. People that decide to risk and open such files due to inexperience or curiosity, will more likely be pounced by some piece of malware. More and more swindlers spread ransomware infections because this is the best virus to monetize and earn on. To prevent getting infected by this and many other channels as well, read our guidelines below. We mentioned some of the most essential tips that will help you maintain high-level protection whilst running online activity.

The process of infection also looks like installing Windows updates, the malware shows a fake window, that mimics the update process.

It uses rdpclip.exe to replace a legal Windows file and to launch an attack on a computer network. After encrypting the files, the encrypter is deleted using the delself.bat command file. Kkia Ransomware virus is propagated via spam attack with malicious e-mail attachments and using manual PC hacking. Can be distributed by hacking through an unprotected RDP configuration, fraudulent downloads, exploits, web injections, fake updates, repackaged, and infected installers. The virus assigns a certain ID to the victims, which is used to name those files and supposedly to send a decryption key. Great tools to protect against Kkia Ransomware are: Emsisoft Anti-Malware and Malwarebytes Anti-Malware.
