How to sniff TCP traffic in a browser from Flash?

Question

Browsers

There is a flash drive that communicates with the server not through the http protocol and traffic is not visible in dev-tools. Communicates over TCP protocol. Are there any solutions for browsers, not for network adapters (like WireShark).

Answer 1

No
Use shark
Filter by ip

Answer 2

In general, it is worth trying to decompile the flash drive and see how the communication with the server takes place. Try to parse the protocol. For this you can use Sothink SWF Decompiler (search on torrents;)).
Or this - www.swfwire.com - it's open source.
You can also try www.monsterdebugger.com/downloads . Perhaps it allows you to intercept traffic.
For browsers, this, I think, is not and will not be. If only some self-written browser based on some Chromium. Haven't come across this.
You can use Wicked Patcher (WP PPC). It works as a proxy, you will need to wrap traffic from the flash drive to it. Plus, it supports lua scripts and you can edit traffic as you like on the fly.
Or, as already mentioned above, use Wireshark. Set up a filter to intercept packets to a specific ip.
