[tetty86@cock.li].video Ransomware

The [tetty86@cock.li].video Ransomware is an encryption Trojan that is installed on the computers of users that click on corrupted advertisements, visit infected torrent websites or open spam email attachments from unknown sources. The goal of the [tetty86@cock.li].video Ransomware is to extort its victims by encrypting the user-generated files, which makes them useless and then offering to provide a decryption software so that the victims can have their compromised data back. They do not say how much this decryption tool will cost but warn that it will depend on how fast the victims respond to their demands and that the victims should use Bitcoins to make the payment. To render the encrypted files useless, they append a file extension, .video to the native file name. The [tetty86@cock.li].video Ransomware ransom note contains the email address that should be used to contact them and the victims' ID, which should be mentioned when contacting them. The text presented by the ransom note reads:

Also, by having an updated security program can prevent infections like the [tetty86@cock.li].video Ransomware.
