Packet Sniffer

This a tool that injects a dynamic library (dll) into a process, hooking its recv and send functions, detouring them to custom ones that records all received/sent data.

Usage

Open a console and run:​

injector <path/to/library> <path/to/executable>

Output is a newline delimited json file saved on the executable folder, named using a timestamp. E.g. 20180808T175623.ndjson. Each json structure represents a packet.

{
  "server":"192.170.58.126:26505",
  "buffer":"48494A4B4C4D4E4F",
  "source":"Client",
  "timestamp":"2018-Oct-15 14:50:37"
}
