I downloaded WhatsApp Sniffer in my HTC Desire, it seems to be working but can't capture any conversation. In short, when I start the app, I can only see the following message:
"There isnn't any conversations yet, wait until one has been captured. Make sure WhatsAppSniffer is listening and if you are on a WPA/WPA2 network, check that the ARP_Spoof is activated."
I've tried the app in both WEP and WPA/WPA2 networks but no luck. My phone is rooted with:
Android version: 2.3.7
Mod Version: CyanogenMod-7-11162011-NIGHTLY-Desire
WhatsApp Messenger: 2.7.8509
Any clues what might be the reason?
