left4dead hacker attack 12-31-08 1:30am
#1
Hello everyone I wanted to post this here on srcds forums to let everyone know about this new attack. I was runing my client on one of the dedicated servers from matchmaking. during the 2nd map in nomercy , the survivors group was sudddenly overwhelmed by hunters that were spawning every 5 seconds. the player whom was doing this was not shown on the server. the console log from my client shows the event so that you have an idea of what was happening. sv_cheats was not enabled on the dedicated server I checked while this was going on to see if I could randomly spawn anything.this is the first time I,ve seen someone who was spawn hacking, and not even in the infected group. hopefully it is just an isolated incident. thanks for your attention.

I went back and checked my server history and found the server where the attack took place.this looks to be one of valves how do I report this?

Well thank you all for responding so quickly to this thread,over 60 views and not one reply. I have seen it numerous times since initially reporting the exploit and unfortunately it is gaining in popularity. unless your on the special infected team or the server op theres really no way to kick the offending player.

A huge bug that needs fixed ASAP was brought to our attention , that in Versus mode you can basically have unlimited boss AI zombies by switching to spectator and switching back. Valve really is dropping the ball on fixing the many, many game-ruining bugs and exploits that have shown up, especially for a company that prides itself on Steam and post-release updates.

Sorry man, I'm not currently running a L4D server, so I haven't been following it much.
All I know is that server stuff is still sorta iffy.
