All about hacks

[aikbix]

Hacking tools can be made often for open source games seeing as everybody has access to the source code. Then again, the same applies for anti-hacks.

well, for something that's 100% modifiable, I'd say nexuiz doesn't have many cheaters at all. If you've ever played ET, that's free but closed source, and it has much more cheating going on there. I think it's the community we've built around it.

I've only seen someone moving that quickly one time. I've never seen it before he used it, and haven't seen it since.

Thanks for the welcome.

This is just a wild guess, but could it be a hack that tricks the server into thinking he has a speed rune?

I was playing a rune game recently and remembered reading this thread.

I thought he was moving to quickly for the speed. Plus he fell quickly as well, i believe.

No, that would be impossible without admin access to the server, since the server never gives/receives that kind of information to/from a client.
Speed hacks usually work by altering timestamps on the network packets, so the server thinks the packet is older than it really is and adjusts the players movement for that lag. dp already tries to detect such manipulations, but obviously there's still a way around those checks.

I have successfully gotten a tcpdump of the speedhack in progress. I can make it available via http or email it. It's 6.1MB in size, approx 5 minutes of traffic.

Almost forgot:

his nick was Mikey Mo, IP 148.137.244.156

Preferably HTTP in a forum PM to me. Thanks.

And... do you have proof he was speedhacking, or a demo too? Especially: was he speedhacking during the whole match or just at times? Still, the dump alone should suffice to find out what he sent, as you also named his IP (which is very useful for filtering the packets).

Edit: Oh, it is already there. DOwnloading...

[divVerent]

I could reproduce the issue. The bug that was used in the dump should be fixed now. Will make a new engine build soon.

Thanks.
