KillRabbit ransomware – a sneaky file-encrypting virus which adds the .killrabbit appendix to corrupted files

KillRabbit ransomware is another dangerous cryptovirus which targets victim's documents right after infiltrating the system via spam. This sneaky threat shows as killrabbitV2-release.bin file which is around 986 KB size. Once installed, ransomware starts encrypting important documents and marks them by adding the .killrabbit file extension to each corrupted file. For example, if you have a file named beautifulday.jpg, the KillRabbit virus will turn it into beautifulday.jpg.killrabbit. Note that this is a serious sign showing that you are infected. After that, files become unusable and can be recovered only after adding the decryption key which is saved on hackers' servers and can be obtained for a certain price which varies from $100 to several hundred dollars.

Paying the demanded ransom is not the best choice when dealing with KillRabbit ransomware. According to malware experts[1], cybercriminals usually leave victims scammed as they seek only for money. Keep in mind that the most of such transfers remain completely secret as they usually involve Bitcoin or another type of cryptocurrency.[2] Instead of supporting hackers and their dirty works, you should opt for legitimate data recovery options.
Kill Rabbit ransomware is typically using the AES-256 encryption algorithm[3] to lock up important user's data. Such an algorithm is used to encrypt data with the unique codes that are different for each of virus victims. This is the main reason, why data decryption is almost impossible, even if it is performed by highly-experienced IT experts. The easiest way to recover files encrypted by .KillRabbit file virus is to use backups. That's why you should take care of them without wasting your time.
The virus is typically encrypting these files:
- Pictures;
- Videos;
- Audios;
- Databases;
- Etc.

Avoid spam emails to prevent aggressive ransomware
Spam emails are the most common ransomware distribution source. Usually, when someone gets the computer infected with a malware form such as ransomware, there is a high possibility that such damaging content came from a phishing message. By using exploit kits and similar techniques, cybercrooks drop such messages to numerous users that, once opened, infect systems and make files that are saved there unusable.
Even if the email seems safe and legitimate, make sure you double check the sender's address, message body, company's name, etc. If you are not expecting anything important at the moment, better delete the message to stay safe. Otherwise, check the file by hovering the mouse over it to see what kind of file it is.
Another recommendation for those who are willing to avoid ransomware would be to install professional antivirus protection if you do not have one already running on your computer. Choose a trustworthy one so that it would work and protect your system properly. Make sure that all updates are done from time to time.
