[ESP8266 Sniffer] Extract Information from Sniffed Packets

Postby bonchenko » Wed Jun 17, 2015 11:27 am

Hello, I am using ESP8266 SDK and manage to sniff wifi packet in promiscuous sniffing mode. I guess what I am getting are packets encrypted in WPA2 PSK.

Please see them in this pastebin url: http://pastebin.com/raw.php?i=YtfkDzqF

I am looking to extract the MAC and IP address of the packets, possibly by decrypting them with the AP wifi password. Any suggestion how to do so?

Maybe a wifi decryption tool in which I can input packets that I get. From there, I can confirm whether if the packets do contain MAC and IP information.

Thanks for your interest in ESP8266 !

We don't get MAC and IP address in sniffer now ,so sorry for the inconvenience.

Hi Bonchenko
Is seems so strange that the new updated SDK 1.1 does not allow to detect the sender MAC in sniffing mode. Maybe this will not be the case in promiscuous mode.
Espressif_Faye say sniffer demo can’t do that in several threads.
It look as big bug in SDK 1.1 if it can't do that after it was public as one of the ESP8266EX capabilities.

…Without the sender MAC, all sniffer / logger application is useless. The main idea of sniffer is to recognize “who is around” and what it send,index by MAC of course.

It can be nice to find colleges to share research. And post here findings.
Can you send me email ? Can we talk over Skype ?
