The most probable attack vector used for the spread of .fox ransomware is malspam. Malspam is a preferred technique as it enables hackers to deliver malicious code on users’ devices with the help of massive email campaigns. Spam emails which are part of attack campaigns usually contain one or more of the following components:

  • A link to compromised web page that is set to download and execute infection files directly on the PC. The URL address to this page may be presented in the form of an in-text link, banner, image, button or full URL address.
  • A malicious file attachment that is presented as legitimate document by the text message. It could be uploaded in a .rar or .zip archive. Such a file could be set to evade active security measures and trick you into running the ransomware on your PC.

Other channels that may be part of the distribution strategy for .fox files virus are malvertising, freeware installers, corrupted web pages, fake software updates, compromised software setups, files shared on forums and other.

In order to complete all attack stages the ransomware needs to establish a few more malicious files on the device. So it could either create them directly or connect a remote server and download them from there.

During the attack .fox virus is likely to access some essential system components and stop certain Windows processes. By doing this, it could prevent being detected by any currently running security measures and continue with the corruption of other system components.

Affected is likely to be the Windows Registry database. Since it contains low-level system settings and app permissions ransomware like .fox often add malicious values there and misuse the functionalities of certain registry keys.

You could recognize the final attack stage by the load of a ransom message on the computer screen. This message is stored in a file named Decrypt.txt

Here is a copy of what it reads:
