S4 Packet Manager - Source only!

[Omdi]

Yo!

It's been an age since I released something to the public.
I scrolled through the and saw my little release there (which is a while back when I put it into the S4 UG).
So I decided to share it with you

This is a Packet Manager which has 2 powerful funtions:

• Block packets
• Modify packets

With blocking packets you can completely deny the client from receiving or sending a specific packet. The second feature offers you to change incoming or outgoing packets (e.g changing your nickname).

Requirements:

• C++
• Visual Studio 2012
• Reverse Engineering Skills

My intention with this release is to convince you of learning C++/Reverse Engineering and that stuff.
C'mon stop being a leecher and learn how to do it by yourself
You can also see this as a little teaser to apply for the .

I should mention that this could be outdated and couldn't work, just update it by yourself if thats the case.
There is an example in the dllmain.cpp but it can't hurt if I post here examples as welll:

Modify Packets:
*
[/code]


If you modify a packet don't forget to call CPacket::finalize() otherwise the server won't accept your packet.

Block Packets:

I don't want to get kicked by HGWC!

                                        Game_BriefingInfo_Ack = 0x5211,

};

So have fun and if you have questions about learning C++ or just about this release, ask them

Btw.: As the title says, this is not a ready-to-use binary!

how to work with autoit???

[Forbidi]

Most of packetsID are really usefull but i don't understand what somes do

PHP Code:

Server_Result_Ack = 0xEA69,
Club_NoticeChange_Req = 0xC368,
Club_InfoByID_Req = 0xC369,
Club_InfoByName_Req = 0xC36A, 


[Exetra]

Gamebreaking hack, we can block roomleave/kick

Server_Result_Ack = 0xEA69

Sends some messages to client, for example "You are wearing an unusable item" and so on
That's from Patch9, so it's pretty old, but they didn't changed the code much since, so it shall still work

PHP Code:

Server_Result_Ack = 0xEA69,
Club_NoticeChange_Req = 0xC368,
Club_InfoByID_Req = 0xC369,
Club_InfoByName_Req = 0xC36A, 


Forgot to explain that:
There are 2 types of packets:

• Requests and
• Acknowledges

Requests are mostly sent from the client.

ServerList_Req = 0x138C
ServerList_Ack = 0x13F0,

As example after logging in, your client send ServerList_Req to the server to request the Server list (German 1, German 2 ...).

The server responds with ServerList_Ack, which contains the server names, location etc.

It does not seems to be complicated at the way you are explain it Omdihar,it should definetively worth a try Thank's! ^_^

What is this for?
Admin_Action_Ack
Admin_ShowWindow_Ack
Notice_AdminMessage_Ack
Is this for a clan or is it what I'm thinking?

Edit: Never mind, most of the clan stuff are the chat server. So this has to be Moderator tools?

[Exetra]

Admin_Action_Ack
Admin_ShowWindow_Ack
Notice_AdminMessage_Ack

Admin_Action => When you send to server a GM command (for exemple "/roomkick Nub1")
Admin_ShowWindow => The client requests if you have the right to open the GM console
Notice_AdminMessage => Broadcast notice

hehe few days later we will se some new hacks in epvp

[dietis]

Seriously it look good for me it's a gamebreaking ^^

[nimano80]

Hmm. I hope this comes to use.

[cheyester10]

This really helped, when I asked about the packet stuff awhile back, I didn't know any commands at all or calling CPacket::finalize() so all I was doing was blocking packets I didn't know.

For noobs, you should learn how to do this. You can learn a lot of stuff, and even have a lot of fun with it!

[Darkryuga]

what is this use? and how to use?

in my eyes as well, packet sniffing IS gamebreaking, something like that shouldn't be released.. look at "bots acclaim" for example!

[Taimless]

oh Gamebreaking look at this ->
