Developed as part of my solution to the 2020 Summerschool CTF, vncreplay replays a VNC session from captured network traffic.
It has some basic functionality to deal with missing or mangled packets, and outputs a standalone interactive player.
First, install dependencies using go mod download.
After that, use go run build.go to compile the project.
The main executable takes an input and output file as its arguments. The input file should be a PCAP file (of tcpdump or Wireshark fame), and the output file will be a standalone HTML file one can open in any modern browser. (In order to help the tool along a bit, make sure the pcap is isolated to the TCP stream containing the VNC capture.)
After that, for most use cases, this will do:
vncreplay -o player.html path/to/capture.pcapThis will result in something resembling the following:
