BDS-PacketLogger

This is a PoC project to log all the packets running throught BDS by using trampoline hook.

Instructions

• Build the DLL using cmake
• Start BDS
• Use your favourite injector to inject the DLL
• Ready to go
• Packet logs are also written to the files under packet_logs directory.

Features

• No hard-coded value used for packets, all dumped from memory at runtime
• Reliable and easy to use, no need to create a proxy
• Don't worry about encryption. Our best friend BDS will handle it for you. LOL.
