According to the researchers, it’s a very dangerous cyber-threat that applies a very strong encryption algorithm to lock almost all types of files such as images, videos, audios, documents, PDFs, databases, presentations and many more with sole purpose to block users to access their data and then blackmails them to pay ransom demanded fee.

Following successful encryption, .kupidon file virus drops a ransom note titled “!KUPIDON_DECRYPT.TXT” on the desktop and informs you about the unpleasant situation. The note includes an email address in order to contact the attackers and get further details. Crooks state that the only way to regain access to the infection files is by using the decryption software that you will have to buy from them. The price of the tool is $300 that has to be paid in BitCoins digital currency. To prove that the decryption is possible, crooks offer to decrypt three infected files for free but that should be less than 10 MB in size.

Should You Pay the Ransom?

You certainly don’t want to lose your essential documents, PDFs, images and other files and may consider dealing with .kupidon file virus authors but still, we strongly advise to not do so. Keep in mind that the only motive of the criminals is to extort illicit money from the victimized people; there is absolutely no guarantee that they will provide you the necessary decryptor even after taking the extortion. There are various occasions when such types of hackers disappeared once the payment is made and caused victims to lose both files as well as money. However, even if they provide you the software that works, the dangerous virus will still remain in the device and can strike again for further incomes. And so, never trust on the hackers under any circumstance and try to remove .kupidon file virus from the PC as soon as possible.
