    In no way do we ever allowed hacked clients on our server - just posting this here for factual information. Zidonuke, I'm more than greatful for this fix - but using it to leverage / test your new 'client' mods - will not be tolerated.

    Over the course of a few days while using this 1.3/1.4 fix - we have crashed (console being frozen) about 3 times.

    Third freeze (5ish mins after Zidonuke logged in?)

    Picture 1)

    I can post the other logs - but I dont feel that its necessary.

    Malicious activity? Was it just to you Kainzo or is this something that others that have used this (I just upgraded away from it this morning) that they/we need to know about?

    Apparently some people were concerned about security or something, so I opened this up. The ONLY changes this makes are that is disables version checks on login, and it replaces your /version text.

    I figured that's all this custom CB did. That's why I was confused by this followup.

    Edit: fixed my typo. Sorry >.<

    But... this isn't a custom client, it's a custom CraftBukkit?

    Kainzo does not seem to be accusing Zidonuke of adding exploits to this CB build.

    Kainzo seems to be accusing Zidonuke of running a custom client, something Zidonuke was readily admitting in the logs.

    Well, you know, so do lots of other people.

    Fixed my typo. Sorry!

    And I was referencing rather then a custom client being used which...many many of us use in one form or another.
  10. Offline


    the /version text was changed using the manifest file and the version checks are removed. There is no security issues.~ The custom client is a side project that I work on with a friend of mine and its more or less for demonstrating the capabilities and possibilities of modified clients and weakness in the minecraft client<->server protocol. In reality I never actually play on other peoples servers and never use hacks in order to cheat because I've only gone on other servers just to be showoffish of the technology created. At no time would your servers be degraded or abused that would cause lasting effects or modify gameplay. From the results of this incident I have decided to step back from my childish actions. I'm regretful for the displays of the hacks on your servers.

    As for the server crashes, I have no clue...

    As I said, this isnt a witch hunt - just an alert - There was correlation between 'said client' and our server hard freezing. Other server admins using this came to me and asked if I had the same issues after certain players had joined.
    I'm not here to spread drama or cause issues, I am only here for facts and awareness.

    If there is nothing wrong here - then move on. Take it as you may.

    Again, thanks for the fix - it is definitely useful - however, an easier and safer way to manage this without the messy /version changes - would be to take the changed .class (NetLoginHandler) and drop it in the Official 556 build - instead of not using an official download of Bukkit. At that point - you will know that the /version reads the same and you can still have the 1.3/1.4 client attached.

    My situation is exactly the same as Kainzo. My server was crashed three (3) times, and before that it was up for 48 hours without crashes. As soon as Zidonuke logged in, the server was crashed over and over. I also saw the fly hacks and run/sneak hack with my own eyes.

    I can post logs that look almost the exact same as Kainzo.

    I really liked the modified server, but Zidonuke is highly suspect.

    What started this is I randomlly told Kainzo on IRC to watch out for Mr. Zidonuke. As soon as I mentioned his name, Kainzo came back with the exact same story as what I told him to watch out for. It seems he did the same on both of our servers.

    Hope this helps..

    Outch that's look bad :s
    but people there is the source code into the one you can check after malicious things?

    Personaly it fixed my problem of overload and add à fine compatibility option for clients.

    That compatibility can be added to the official bukkit release?

    This evening Zidonuke has taken it upon himself to go on a mass server crashing rampage. Rest assured his exploits will be fixed, and he is banned.
  16. Offline


    I can confirm what Dinnerbone said. Zidonuke broadcasted his rampage on livestream, using a hacked client to crash the top 100 servers on some list he had. He then logged onto Doridian's server to brag about it, and received a warm welcome. I recall Doridian was another MC modder who also wrote exploits and backdoors into his program to be used maliciously against servers.

    I also heard he threatened a few servers who were running his mod, saying he was being paid by friends to take them offline.

    Anyone using this person's mod should immediately STOP using it, it is malware infested.

    The server modification itself is clean, as of time of writing. No guarantee he won't edit something in after this post.

    I was right. Removed link. Topic locked.
