KRider Ransomware

From what our researchers have learned KRider Ransomware appears to be a file-encrypting malware. Unlike most of other similar threats that display a ransom note, lock the screen, or somehow else deliver a message from their creators, this infection does not do any of these things. Perhaps, the malicious application is still in development, and the cyber criminals did not create a note with their demands yet. In any case, it means there is only one thing to do if you were unlucky to encounter this threat and it is KRider Ransomware’s removal. Hopefully, you have any copies of files that were encrypted somewhere safe as it is probably your only chance to recover files locked by this malware. Nonetheless, before you make any recovery attempts it would be best to remove the infection first; this you could do manually if you take a look at the instructions located below the text.

Currently, our specialists are still not sure how widely KRider Ransomware could be distributed provided the malware is being spread. Based on our experience with ransomware applications we can say they are often carried by malicious files sent through Spam emails. For example, users might receive suspicious pictures, text documents, etc. Thus, the infected attachment may not look harmful at all. For this reason, it is advisable to be extra cautious with any files received from unknown senders or ones that raise any suspicion. Whenever you have doubts, you should use a reliable antimalware tool. Just scan the file before opening it, and the tool should tell you whether it is harmful or not. Then you can erase the file with the same antimalware software or use it if it appears to be not dangerous.

Furthermore, while testing the ransomware we noticed that besides the infected file downloaded by the user, it might create more malicious data. Such files may have random titles and they could be placed in directories where encrypted data is. Afterward, KRider Ransomware may begin the encryption process during which it could lock various files found on the user’s computer. For instance, the malware might damage data with the following extensions: .png, .ai, .avi, .bmp, .doc, .docm, .docx, .efx, .fla, .flv, .java, .jpeg, .jpg, .m3u, .m4u, .mov, .mp3, .mp4, .msg, .pdf, and so on. All encrypted files might be given a second extension called .kr3, so a picture named as panda.jpg could look like panda.jpg.kr3 after it gets marked by the infection.

Normally, such threats display a ransom note in which the malware’s creators demand users to pay a ransom if they want to get a decryption key, which is necessary for the decryption process. However, as we mentioned earlier, the infection’s creators do not demand anything. In fact, the research reveals that KRider Ransomware does not even save the decryption key, which should be created during the encryption process. It means you could not decrypt any data even if you would be able to purchase a decryption tool. Therefore, we urge you not to hesitate anymore and erase this malicious application from your system as soon as possible. Once you clean the computer, you could try to recover files from copies if you have any on an external hard drive, flash drive, cloud storage, and so on.

To get rid of KRider Ransomware manually, you would have to find the randomly named files related to the malicious application. For detailed instructions have a look at the steps provided below as they will mention a few possible locations where you might find such data and show you how to remove it too. Since this might appear to be too complicated for some of our readers, we may also suggest deleting the malware with trustworthy antimalware software. If you choose this option, you only need to install a reliable tool, let it detect the infection along with other possible threats, and click the deletion button that should appear right after the full system scan is completed. This way users can secure their systems too as the software could guard the system against various threats.
