Garry's Mod
A sandbox game for the PC, Mac and Linux

Garry's Mod is a Sandbox Game based around the idea of building. Unlike most other games there aren't any objectives - you can't lose and you definitely can't win.

Exploit Fix Released

👤 🕔 April 19, 2014 272

An exploit was released last night that took advantage of the Source Engine’s file sending mechanism which made it possible to send files with any extension to the client or server. This exploit is likely still active in all other Source Engine games so I’m not going to go into specific details about it.

Needless to say that this was exploited in Garry’s Mod on Windows to send dlls to clients and servers. As far as I am aware the exploit wasn’t used to do anything malicious beyond propagating itself, spamming chat and changing server names. But to be safe I would recommend that you consider deleting your Garry’s Mod install and starting fresh. It might be a good idea to do an online virus scan too.

The patch I released this morning attempts to clean up any mess left behind by these exploits and patches the variety of methods which they used. If anyone has further information about the exploits, or any exploits left un-patched please email me personally at

    I have a DarkRP server, and once i updated it, it has the “error” i guess saying that “The server is running an older version of the game than you”
    Any suggestions or fixes?

      This is a serious post about a dangerous exploit. We don’t need idiots like you running around “trolling” people about things they already know.

    Hello Garry! My brother has some pretty unusual occurrences after this exploit, he is not able to look at any profiles, only message them, however he’s not doing the *coughs* when he does. He deleted Garrys Mod via Steam and in the bianary so there should be no files left. Yet he cannot install Garrys Mod again, any fix on this?

    I still am getting effected from the virus. When I press certain keys, that have a function, the only thing that happens is a message pops up saying: vinh’ll fix it, even though I have updated gmod, I have reset the controls to default but it still says the message. I have even deleted all local content and re-downloaded gmod but it has done nothing. Help me Garry, your my only hope.

    Please make swimming animations work every time and actually switch back to the normal animations when you get out of the water.

    Please fix the recent LAN issues where odd things seem to connect each player for example: all players can undo other players props.

    Please look into a possible fix for an event where if you are in water and coming out again just as you temporarily loose connection to the host (EG the host has a lag spike due to loading a big script.) then the underwater loop continues to play for the client when they are no longer in water. I assume this happens with other loop sounds but I came across this one in particular because I was trying to fix the swimming animation bug.
