An old ransomware seems to have emerged once again. KeyBTC is the name of this ransomware as it appends the extension [email protected]_com to encrypted files. To remove the ransomware and see if you can restore your files, you should carefully read this article throughout.
Short Description The ransomware encrypts files with RSA/PGP algorithms and asks for payment via email.
Symptoms Specific file types are encrypted. Two files are created on the user’s desktop – File1.bin and File2.bin along with a .txt file with instructions for paying the ransom.

It is unknown if exploit kits or social media are used to further help in the distribution of this ransomware, but it is a possibility. File sharing services might contain such files as well. If something looks suspicious and you are not one hundred percent sure of its origin, do not open it. At least that is the general rule of thumb.
The KeyBTC malware is a known ransomware. The legend goes that it used to target only Russian speaking countries. Alas, in late 2014 it began infecting users worldwide. Still spiraling to this day, it is not one of the most dangerous ransomware types, but it is quite effective. KeyBTC nowadays might have evolved and try making entries in the Windows Registry as other ransomware. This maneuver is done to keep malware’s persistence while loading with each boot of the Windows OS.
What makes this ransomware effective and still viable to this day is that it encrypts important files, which are still the most popular types of files used to store personal information. Another thing is that everything but the public encryption key is not sent anywhere and only known by the malware maker.
– FILE1.BIN and FILE2.BIN files (check your desktop and local disks to find these files or just use Windows Search.
– One of your encrypted personal file for test decryption. Supported types: DOC/DOCX, JPG/JPEG, PDF. Maximum file size: 3 Mb.
– Your decrypted file, proving that we can really help you.
– Decryption price and payment details.
4. Receive decryption key and detailed instructions how to decrypt your files.
– You must contact us in 24 hours, unless the price will rise.
– Nobody can help you except us. It is useless to reinstall Windows, rename files, etc.
– Your files will be decrypted as quick as you contact us and make payment.
Paying up is strongly unadvised. You might be unable to unlock your files in the end, but also, might not be contacted back by the cyber crooks at all. That could serve as an inspiration to them to make the ransomware tougher.
After the encryption, all files have the extension [email protected]_com, which is also the email you are instructed to contact the ransomware creators. Shadow Volume Copies might not be of much use here, as files are not only encrypted but put into the .bin files mentioned earlier and not deleted as other ransomware types tend to do.
