are you sure that is how the packet is structured? get a higher score and look at that packet .

cause it might be like aa 55 55 55 39 99 99

the real going packet is

score:1
(73636F72653A31)
but all i can do is just filter it as score:9
(73636F72653A39)
beacuse when i try to do make it 9999 packet becomes
73636F72653A39393939

so i cant filter "73636F72653A31" to > "73636F72653A39393939"

beacuse the filter is more big then real packet Mad

anyone know how to do it Rolling Eyes

pls try to understand what i want to say Rolling Eyes

let me explain such:

Quote:
{"points" : [2,0,2,0],"stype":"score","p":3,"m":1,"type":"score","target":"server"}


this is the real packet is going on ,

i success when i try to filter as

Quote:
{"points" : [9,0,9,0],"stype":"score","p":3,"m":1,"type":"score","target":"server"}


but i dont know how can i add a filter that will let me filter this

Quote:
{"points" : [2,0,2,0],"stype":"score","p":3,"m":1,"type":"score","target":"server"}


to

Quote:
{"points" : [999,0,999,0],"stype":"score","p":3,"m":1,"type":"score","target":"server"}



if u ask ; why cant i ,beacuse the filtered packet is more big than the normal packet Rolling Eyes [/code]

Only thing that you can do is to first find send function adress by tracing from the Winsock.Send command you can do this with ollydebug with any version after you find snd_fnc adress add that into CheatEngine then open that adresses in memory after you can put a breakpoint there to see the going packets without encrypted forms...After you should write your packet sender program in C# or C++ when you write that program after its easy to filter anything you want etc..


So when you do this and find going packets after breakpoint look what access to W32.Send pointer there you should see thing like mov eax...etc mostly ur score will be stored there before sending to server like in eax..or anyother then edit those and packets will be like orginal cause it will just send as its do usually...
Then u wont need to do like this...Sorry for the bad english and bad explanation...

I thought it was an multiplayer game and such as....With which program did you filter those packets...

Did you try Tamper Data with firefox ?
Did you try WPE ?
Did you try WireShark ?
or game can send score for highscores with encrypted like in miniclip...

i didnt try wireshark

and it doesnt encrypt packets + sends packets to server on established socket doesnt create a new http request
