Media-Type based filters located at HTTP/HTTPS proxy level should be able to detect media types exactly and
should not bypass files because of faked content types or unknown file name extensions etc.
Faked Media-Type Examples
|QUICKTIME.GIF||( HTTP | HTTPS )||Renamed quicktime movie quicktime.mov -> quicktime.gif|
|VIDEO.HTML||( HTTP | HTTPS )||Renamed mpeg video video.mpg -> video.html|
|EICAR.JPEG||( HTTP | HTTPS )||Renamed malware test file (will not do any harm to your computer) eicar.com -> eicar.jpeg|
