[PACKETBOT] Why it is still possible!

[Maurice]

Hello, I'll show up with a quick guide of the possibilitie's for a packetbot is still in the run.


First of all

The packet's are handled as the same structure/handling/encrypting (It are just bit's, since Darkorbit has this a long time it is possible for seafight to)..

The Encryption/algorithm story is partly true, but doesn't contain's any difference as Darkorbit. And since it is possible to make bot's for Darkorbit, it should be possible for Seafight to?

Well then make my day

I've been sniffing, and disassembling the SeafightMain.swf, and found a few (funny) things..

Packet B (Also known as: B|2.1|blabla)

0000   00 17 42 26 00 00 04 20 10 00 01 90 0c cb 00 00  ..B&... ........
0010   01 40 00 01 00 03 32 2f 31                       [email protected]/1

As you see they still use it, but with another structure..

Packet LOGIN (Also known as: LOGIN|BLABLA|BLA)

0000   00 00 2e b4 57 00 00 41 83 ee 7c 70 00 00 00 00  ....W..A..|p....
0010   20 31 30 35 66 62 65 66 33 61 62 65 37 36 36 37   105fbef3abe7667
0020   39 63 36 61 34 37 39 32 39 31 37 33 65 66 63 65  9c6a47929173efce
0030   38                                               8

And as my SID was (At internalMap.es): 105fbef3abe76679c6a47929173efce8
It is the login packet with some other bit's again..

Ahh!! A Orca??? Mahhh Gawd!

Also the X Packet (For placing a monster/item, correct me if I'm wrong) is also still in it, with... ofcourse other bit's :-)

As you see I've made a great process in this shizzle.. and I'll start to get some C# Classes to handle and respond with the correct Bit handling etc.

Stay tuned!

[levlevliva]

That mean, you want to make a bot like seabot?...

[Maurice]

Yes, and other people like Nikka etc can get they're bot online again to.

First of all, it's really refreshing and a nice change to see someone with some decent skills in reverse engineering and packet handling here.

When they changed the protocol I also investigated a little bit (using actually the same tools like you did - a disassembler and Wireshark). I didn't spend too much time on the reverse engineering of the protocol though. Like you say, it's just byte based and with some time it should be possible to decipher the most relevant parts. The tricky part might be to actually send commands.
On a side note, I'm pretty sure that the "Red Corsar" package you show in the example actually consists of two packages. I've seen those prepended messages alot, but I'm not sure what they are actually. Maybe some kind of resync?

Btw, did you manage to actually decompile the SeafightMain.swf? Or did you only disassemble it? I'm asking because the obfuscation breaks all decompilers of my knowledge, and the disassembled code is truly painfully to read..

One more thing: Try to get the debug log of the client to work. The seachart is launched with log-parameters for flash, and in some way you can attach a logger there. This was used before, and you could even display that log in earlier versions of the client. If you can get that to work, it will be a huge help to decipher the protocol, as the log basically shows what each package means in detail.

Anyways, great to see you are investing work on the topic. If you are able to create a library for the protocol, that would be truly amazing.

I got the old Encoding files from the R63b version of Habbo.. which used the same system/structure with Reversed Byte's.. so it would work.. but I can't find the packet structures in my decompiled swf I got..



U may look at it maybe u can get something.. Program used to decompile: AS3 Sorcerer 1.40

hey guys what i have to say is now in darkorbit packet bots are possible but if you use them you get an instant ban and also when the encryption started darkorbit bot developers were updating they`re bots every 2-3 days because darkorbit made updates at 2-3 days so think about it lets say its possible to make a sf bot but will you spend your time 24/7 on pc to update it everytime? and then what will they introduce the same stuff like on darkorbit packets send=ban|?

Lol, again that romanian geek.. I'll sent Kpt.Terror if u won't get out here man..
Go talk trash somewhere else.. Darkorbit isn't updating ever 2-3 day's.. and instant ban is also bull***.. look the map's dude..

Not bad, it would be great to find the new encryption algorithm.
I'll make the SeaBot working again.

I decompiled the SeafightMain and this should be the function that send the packets (variables are been renamed for a better understanding):

private var sf_socket:Socket;
private var bytes:ByteArray;

public final function send(param1:SFPacket) : void {
         if(!this.sf_socket || !this.sf_socket.connected)
         {
            return;
         }
         this.bytes.clear();
         param1.encrypt_function(this.bytes);
         this.sf_socket.writeShort(this.bytes.length);
         this.sf_socket.writeBytes(this.bytes,0,this.bytes.length);
         this.sf_socket.flush();
      }

But if i understand well, each object has a different algorithm.
This is the main class:

package SFObjects
{
   import flash.display.Stage;
   import flash.events.MouseEvent;
   import com.bigpoint.seafight.tools.*;
   import flash.display.DisplayObject;
   import flash.events.Event;
   import flash.utils.IDataInput;
   import flash.utils.IDataOutput;


   public interface -_----__-_
   {

      function -__--_____---() : int;

      function -----_-_-__-() : int;

      function -_-_---_____-() : int;

      function ---___-_---_() : int;

      function decrypt_function(param1:IDataInput) : void;

      function encrypt_function(param1:IDataOutput) : void;
   }

}

And this is an example of a single object:

package Object
{
   import ---______--_.-_----__-_;
   import flash.utils.IDataInput;
   import flash.utils.IDataOutput;
   import flash.display.MovieClip;
   import flash.geom.ColorTransform;
   import flash.display.Bitmap;
   import flash.geom.Point;


   public final class -----__-_-__ extends Object implements -_----__-_
   {

      public function -----__-_-__(param1:int=0) {
         super();
         this.duration = param1;
      }

      public static const instance:-----__-_-__ = new -----__-_-__();

      private var _version:int = 0;

      public var duration:int = 0;

      public function -__--_____---() : int {
         return -7998;
      }

      public function -----_-_-__-() : int {
         return 0;
      }

      public function -_-_---_____-() : int {
         return this._version;
      }

      public function ---___-_---_() : int {
         return 2;
      }

      public function decrypt_function(param1:IDataInput) : void {
         this._version = param1.readShort();
         this._version = 65535 & ((65535 & this._version) << 16 % 16 | (65535 & this._version) >>> 16 - 16 % 16);
         this._version = this._version > 32767?this._version - 65536:this._version;
         this.duration = param1.readShort();
         this.duration = 65535 & ((65535 & this.duration) >>> 15 % 16 | (65535 & this.duration) << 16 - 15 % 16);
         this.duration = this.duration > 32767?this.duration - 65536:this.duration;
      }

      public function encrypt_function(param1:IDataOutput) : void {
         param1.writeShort(-7998);
         param1.writeShort(65535 & ((65535 & 0) >>> 16 % 16 | (65535 & 0) << 16 - 16 % 16));
         param1.writeShort(65535 & ((65535 & this.duration) << 15 % 16 | (65535 & this.duration) >>> 16 - 15 % 16));
      }
   }

}

It's an hard work but not impossible

lol i am not kpt.Terror and also trust me there wont be no new packet bots

than if instantban is bullshit why kbot/ibot is offline?

[fato90]

kpt.terror is a lot.. no?

[terrorise]

@fato90 , kpt.terror is me
@willie hey mate,i see u started doing your stuff again, very nice, i really appreciate it
@ionutzel222 dont make me find your ip,we live in the same country, you can get your *** whooped really fast.stop trying to show everybody else how **** smart you are,because, guess what, you AIN'T!
you're just a wanna-be , at first u wanted to be a mod, greatfully epvp staff recognised your "qualities" and didnt inherited you with any ranks, thanks *** for that! after that you wanted to expose me in some stupid way like i'm a bad guy who steals and re-sells accounts..
you ****** dumbass have i ever uploaded anything on this site and had any bad feedback about viruses? i guess not.i'm just a reseller, sold many ships, and i still get offers for it, seems like i got charm and i can find buyers for them easyer than the owners, or i got more time for this kind of things..so keep your mouth shut, and listen, read, be observative, maybe, someday, you'll learn something...'till then..STFU

[ionix123]

Iontzel play on server global europe 3 if you watch top 5 he's name is ...Maximus... , an idiot, really arrogant. He was admin on server global europe 2 but they catch them putting items and other things like pearl, scharpnel.. And then he starting to play at gb3 and he got the most of the admins in he's hand. And he talk alot alot of *****. I can put if you want right now here he's adress. Some time ago he did putted pearls on my acc and he wanted money so i know he's adress because i did it via wester union. I don't tell if for the moment.

[Maurice]

AoHAhahaAHAh Fight those internet famewar's somewhere else By the way thanks for the packet structure base InsiDe!

[terrorise]

ionix...you might be my new best friend in this case ))

btw, you got some fake info's about this little ***** aka ionutzel222 .
he was never an admin, he's too young and stupid for that, he's like 15 or something like that, the boat he has now, it's stolen,i know from who he stole it also.

and no, he aint got no admins in his hand, his only admin friend was a finnish mod, one of my best friends, he screwed some things up and messed up the whole thing.

if he claims to be selling pearls and stuff, he's probably re-selling dialer's items, the money get's to him first, keeps his cut,then speaks with dialer as he would buy for himself...

ionix123 add me on skype at kpt.terror , wanna speak with u a little

and trust me, this little ***** aka ionutzel222 was never an admin,on any server,doesent know admins, he's a piece of .... , who just pretends to be smart

[Nonge_II]

also heist das es doch möglich ist mit packet bots zu arbeiten ?
