Nasty exploit found in the Source Engine. BEWARE!

So I think yesterday an exploit has been found that can make you download a RAT, that will steal your items from TF2, CS:GO, Dota and Steam, and then maybe even get you VAC'd.

Not sure if it affects TF2 or CS:GO, so look out joining random servers out there.

I know.

But still, it's better that people know that a mod can be affected by the exploit. Same with people that play CS:S or DOD:S, those are affected as well.

This is the umpteenth Source exploit of this type. Everyone should already have been running with cl_allowdownload and cl_allowupload set to 0 by default and only setting those cvars when you absolutely need them and trust the server (even then, some of these exploits are player-to-player, so even if you trust the server you can get pwned). If you're playing with those set to 1, change your configs now.

Exploits like this have been out in the open for months without Valve fixing them, and sometimes the reported fixes get bypassed in a few weeks, so even when this gets fixed, keep those features disabled.

this is scary

i already had sprays/download/upload turned off, but that's still insane how people could find an exploit based on someone joining a server

There's a reason to say believed. If anyone figured out if it worked/didn't I would like to know. Thank you for your input.
