YafunnLocker ransomware attacks the virtual community

YafunnLocker virus has set out into the cyber wild. Since it is another file-encrypting malware, it is able to encrypt the files with an elaborate cipher. Its name stems from an email address which is displayed in the ransom note of this virtual threat. You might get informed that you must contact cyber criminals via to remit the payment of one or two Bitcoins. The most important thing related to this virus is that it encrypts your files with the RSA-2048 algorithm. The key which is generated by this code cannot be easily guessed, so the only possible way to recover your data seems to be the financial transaction. However, this might be futile. We highly recommend staying away from this data recovery method. Therefore, you should deal with YafunnLocker removal procedure first.

Talking about the virus itself, there are interesting things that can be pointed out. For instance, some researchers associate YafunnLocker ransomware with the CryptoLuck family what uggests that this parasite may be deployed on computers via RDP, TeamViewer or other vulnerabilities it finds within the system’s perimeter. Howwever, some users report that the virus hijacks DLL via a fake GoogleUpdate or is simply delivered by email. What is certain, though, is that at least to some extent, the virus developers take advantage of the Rig exploit kit which has just recently been found to spread another major ransomware infection – the Locky virus. Either way, finding such a virus on your computer can be very stressful — you have lost access to your files and some strange pop-ups are demanding you to pay to make things right again.

Though this technique will not help you decrypt the files, it is a much better option than keeping the virus on your computer and allowing it to lock your future documents or programs.
