In todays time one of the most successful way of gaining information such as passwords,user ids etc in LAN (local area network) is through
man in the middle attacks . Let me not go into deep into Man in the middle attacks, just try do some
googling but in simple words it can be explained as attacker or a hacker listening to all the information sent in between the client and the server .To prevent these kind of attacks Email providers started using
Hypertext Transfer Protocol Secure (HTTPS) It is a combination of the
Hypertext Transfer Protocol(HTTP) with SSL
(Secure socket layer )protocol to provide encrypted communication between the client and the server .So when a hacker caries out a Mimt attack the victim is cautioned with a invalid SSL Certificate
In this tutorial I will teach how to carry out a successful Mitm attack
Concept :-
We Know that HTTP (Hypertext Transfer Protocol )simply sends all the information through plain text .So if we make the victim use HTTP instead of HTTPS to connect sites like Gmail , Pay pal. we will be able to carry out a successful Mitm attack with out causing any suspicion To do this we are going to use a tool called SSL strip
Thing we Need
1. SSL strip: You can search Google for SSL strip it comes both in windows and Linux versions . I will be using the windows version in this tutorial
2. Ettercap to carry out mitm attacks
Demonstration :-
1. Open SSL strip and fill in all the required information for arpsoof, network ,ssl strip, change data .If you don’t know what to enter simply click auto check . remember to check if HTTPS to HTTP is included in Change data , finally click ok
2. Now select the victim’s IP and click open
3. Now open ettercap go to
sniff -unsniffed sniffing and select your network interface and click ok
4. Now select
hosts-scan hosts .Once scanning is completed .Open host list from hosts tab .Now select the IP address of the router as target 1 and the victims IP as target 2
5. Now select mitm-arp poisoning and click ok as shown
6. Finally select start-start sniffing .Now when the victim logs into gmail he will be using
HTTP and not
HTTPS Hence we are able to get the User id ,passwords as shown below
Counter measures:
1. whenever you perform an online transaction such as Credit card payment, Bank login or Email login always ensure that you Use
HTTPS
2. Always check the
SSL certificate before doing an online transaction
