Hai...
Anyway, as long as I can see in this forum, all the hacks are using memory writing which is kinda good (cheatengine hacks tracking, etc).
Is there someone here that tries packet editing? it is usefull and NOT THAT HARD.
Usually when packets are ready they gets encrypted and send which make the possible reason that it will be before ws2_32.send call (reversing).
sooo.....
The simple consept of finding the packets encryption algorithm:
track ws2_32.send/ws2_32.recv, trace, log packet untill you sick and you've found the decryption address (which is probebly a function).
after tracking the address you can try reverse engineering and understand the encryption algorithm (you need to know about encryptions for that) OR a Hook.
The simple consept of packet sniffing:
Detour ws2_32.send/recv.
If it's a hook then log packets to your window or something which isn't that hard again.

Packet editing gives and rich and creative hacks like:
kill your mate :P..
kill yourself.
kill everybody.
gain 9999999 exp.
unlimited (all)...
speed.
one shot kill.
ETTTCCCCCC use your creative mind :].
