See who the Imposters in an Among Us round are without a modded client (just using Wireshark).
I do not recommend using this in public rounds, as this ruins the game for others. This is just a showcase for what is possible if a game is implemented client-side.
Open Wireshark, start listening on your Internet Connection and filter for
udp && data.data[0] == 01 && data contains 40:1c:46:00 && frame.len > 100.
After a round starts a new package should appear. Select the package and right-click on the hex dump which appears at the bottom of the window.
Press "Copy Bytes ...as a Hex Stream" and paste the result in the text field of the parser.
Now you should be able to see who the imposters are in the table below.
In case you want to try out the parser without running WireShark + Among Us, you can just copy the hexdump from the example_hexdump.txt file into the parser and try it out that way.
It should look similar to this:
