Send packet

[shadowKD]

Good afternoon. Trying to figure out how to send packets.
Found a function to send a package

//4.3.4

 
NetClient::Send2 = 0x489590 
currentConnection = 0x9BE7E0

I also roughly understood the package template.
Took as an example ([SourceCode C#] Hook and Monitor of SendPacket)


I could not find the offset dataStore1. Can anyone tell me how I can do this?

If you found send function, you can easily find CDataStore offset.

void __fastcall NetClient__SendEx(__int64 a1, __int64 a2, unsigned int a3)
{
  __int64 v3; // rbx
  __int64 v4; // rsi
  signed int v5; // edi
  __int64 (__fastcall **v6)(); // [rsp+20h] [rbp-28h]
  __int64 v7; // [rsp+28h] [rbp-20h]
  __int64 v8; // [rsp+30h] [rbp-18h]
  int v9; // [rsp+38h] [rbp-10h]
  int v10; // [rsp+3Ch] [rbp-Ch]

  v6 = CDataStore;
  v3 = a2;
  v7 = 0i64;
  v4 = a1;
  v8 = 0i64;
  v9 = 0;
  v5 = a3;
  v10 = -1;
  sub_1402BD400((__int64)&v6, 16);
  (*(void (__fastcall **)(__int64, __int64 (__fastcall ***)()))(*(_QWORD *)v3 + 16i64))(v3, &v6);
  v10 = 16;
  NetClient__SendExEx(v4, (__int64)&v6, v5);
  v6 = CDataStore;
  if ( HIDWORD(v8) != -1 )
    CDataStore__InternalDestroy(&v6, &v7, &v8, (char *)&v8 + 4);
}

note: this decompilation is from retail 33237 build.
