I don't know exactly how to call it, well it's definitely a guy trying to hijack accounts here.
I got a message from a friend: Hey man, just created a new teamspeak server,http://eurots2.gameservers.com:9372, come join and let's play! The sound Codec you are required to download is the one that was recently implemented in CS:GO, and I thought it was nice to have on the teamspeak server as well. Invite your friends and let's build an awesome TS community! If you join soon, I could maaaaybe give you admin. If you ask nicely.
He's using the recent CS:GO voice codec as advantage to hijack accounts here.
I went on the TeamSpeak 3 and got this message: http://oi58.tinypic.com/315jtdc.jpg Then you get redirected to this link which INSTANTLY brings this .exe file with "the new CELT codec" that has been implemented in CS:GO to your PC. With launching this .exe there's no window opening but instead this virus is implementing a remote on your PC. Like this, he's able to control your PC. To fix, disconnect from internet and do a system recovery.
Don't be stupid. If you are, you really don't deserve your skins. Please do not click any links!!
