Download Protection: RAT files are not checked on Windows

Reported by resea...@nightwatchcybersecurity.com, Apr 5 2016

Issue description

VERSION
Chrome Version: 49.0.2623.110 (Official Build) m (32-bit)
Operating System: Windows 2012 R2; version 6.3.9600

REPRODUCTION CASE
RAT files carry PICS rules which would allow modification of IE's trusted zone settings. Currently Chrome will check these if they are under a .PRF extension but not .RAT. We can provide a patch if needed.

Sample file here:

Could you please share an example of a file that modifies IE's trusted zone settings as you describe? The file that you shared doesn't seem to do anything when double-clicked.
We did some more digging and it looks like that RAT / PRF files only modify the Internet ratings in IE, which would only affect users that have ratings turned on. It does not affect the trusted/untrusted zone.

Downloading RAT/PRF files does not lead to download of executable files controlled by an attacker so this does not fall under the Download Protection VRP program.

For all Download Protection VRP bugs: removing label Restrict-View-Google and adding Restrict-View-SecurityTeam instead.
