some1 just seems to have found an exploit in zero k which allows him to take over accounts and write and play as them and easily hijack admin powers.
it just threw me out a game "connection refused, user already ingame" and when i was in lobby i see "snokerciffer: its ok now" what i never wrote.
also chesti and alcurs accounts have been used to exit our games and kick users also tried to ban!

It seems whoever is doing it, is spoofing ingame player name, not actually taking over the account. I hope.

DErankexploit is often found in zk.

Is Spring doing any kind of authentication? Else this would be an engine bug that can't be addressed directly by zkdevs.(Turned out I was wrong and Spring does authentication while zk ignores this feature). I could think of a modified startscript.
[Spoiler]

FIrankAdminAlcur enabling cheats and DErankChesti kicking people seems normal behaviour to me..

What I can confirm is that someone joined one game using my accountname and did "!kick Alcur" and "!exit". I was in lobby room, but didn't even have Spring running. Apparently he did the same with Chesti's and Alcur's names too.

I guess this means we should just go back to our families/friends and have a nice Christmas Eve while the trollz without friends can enjoy the evening as well.

"I guess this means we should just go back to our families/friends and have a nice Christmas Eve while the trollz without friends can enjoy the evening as well. " do you write this to all forums today?

well i think this is a serious security lack if some1 can hijack admin accounts and kick and ban people and this should be taken serious

I agree with snokeciffer. This is a serious exploit and it must be fixed immediately else we risk losing more people in this one mess of a christmas parade lel.

This has been known for ages. The engine does authentication but the ZK autohosts ruin it.

@snokeciffer
You have to read between the lines.
This can only be used to spoof names ingame and won't give access to the database or website. Afaik there are some nice CZrankAdminLicho only(Lvl99) Springiee commands though.

I just tried and am able to reproduce the issue. Firepluk can still have fun, but maybe not for long.

Taking over some1 elses nick gain you his power untill next logout.

@Rafal[ZK] remember when you once changed nick to trollsomething and I ninjaed your nick? I was able to join #zkadmin easly, even tho my account itself didn't have such permission. (And noone noticed cuz same flag, lulz)

"This can only be used to spoof names ingame and won't give access to the database or website. "
i have seen this gives access to admin commands which affect the database (kick and ban)

even if it doesnt effect the db
i dont want to get kicked by script kiddies with no reason and tips like "lets just chill let them destroy zk completely and instead of doing anything we have a great christmas" is no real help so whats the sense of this`?

It seems that the easiest way to hack zk is just look for some exploits is reported issues.

I think would be better to put down the affected services (springie if I got it correct) rather than let them be and have a couple of trolls annoy people.
