Ask HN: How to capture IoT network traffic?

4 points by grezql 7y ago

I have a Smart TV and a Bose QC. I dont trust either of these. How can I capture the network traffic? Are there any Wifi routers out there that supports packet level inspection?

Does Wireshark work for this purpose?

  I dont think so? Wireshark will capture the packets sent to/from my PC only? The other packets, if network card is capable of promiscious mode, will be encrypted?

There is a tcpdump/wireshark module on OpenWRT. You might want to go with a router that is capable to capture and store the dumps like the extendable Turris Omnia. Highly recommended router.

    I vaguely remember the pineapple from HAK5 can do MITM stuff. Not sure whether that could be used to unveil encrypted traffic from your devices to their homes.
