How to Prevent RM and WMV Trojans in network security

(1) adding Trojans to RM and RMVB files

Helix Producer Plus is a graphical professional streaming media file production tool. This software converts files in other formats into RM or RMVB formats, you can also re-edit the existing RM file. During editing, you can insert the prepared webpage Trojan. In this way, as long as the edited media file is opened, the webpage Trojan inserted in it will also be opened, and even the webpage Trojan's opening time can be controlled to make the webpage Trojan more concealed.

(2) how to add Trojans to WMV and WMA files

For WMA and WMV files, you can use the default Player Windows Media Player's "Microsoft Windows Media Player digital permission management to load arbitrary web page vulnerabilities" to insert Trojans. When you play a malicious file that has been inserted with a Trojan, the player will first pop up a prompt window, indicating that the file is encrypted by DRM and requires URL verification certificate, this URL is the webpage Trojan address set in advance. When the user clicks "yes" for verification, the trojan is successfully planted. Like RM file Trojans, we still need the same tool-WMDRM package encryptor-to insert Trojans into WMV files. This is a file that can encrypt WMA and WMV by using DRM, the software itself is designed to protect the copyright of media files, but in the hands of attackers, it becomes an accomplice of hackers.
