Windows 7: Steam URL protocol can be abused to exploit game vulnerabilities

Steam URL protocol can be abused to exploit game vulnerabilities

Quote:
When the Steam client is installed on a system, it registers itself as a steam:// URL protocol handler. This means that every time a user clicks on a steam:// URL in a browser or a different application, the URL is passed to the Steam client for execution.

Steam:// URLs can contain Steam protocol commands to install or uninstall games, update games, start games with certain parameters, backup files or perform other supported actions.

Attackers can abuse these commands to remotely exploit vulnerabilities in the Steam client or the Steam games installed on a system by tricking users into opening maliciously crafted steam:// URLs, ReVuln security researchers and founders Luigi Auriemma and Donato Ferrante said in research paper published on Monday.

I've not seen anything suspicious yet, outside of random people trying to start chats claiming to be with steam
I usually just troll them for 5 or 10 minutes and block...
