How To Sniff Password Using WireShark

Follow The Steps 


Requirements : 

1. Wireshark Network Analyzer (wireshark.org)

2. Network Card (Wi-Fi Card, LAN Card, etc) fyi : for wi-fi it should support promiscious mode


Step 1: Start Wireshark and capture traffic
In Kali Linux you can start Wireshark by going to
Application > Kali Linux > Top 10 Security Tools > Wireshark
In Wireshark go to Capture > Interface and tick the interface that applies to you. In my case, I am using a Wireless USB card, so I’ve selected wlan0.



Ideally you could just press Start button here and Wireshark will start capturing traffic. In case you missed this, you can always capture traffic by going back to Capture > Interface > Start



Step 2: Filter captured traffic for POST data
At this point Wireshark is listening to all network traffic and capturing them. I opened a browser and signed in a website using my username and password. When the authentication process was complete and I was logged in, I went back and stopped the capture in Wireshark.
when wee type in your username, password and press the Login button, it generates a a POST method (in short – you’re sending data to the remote server).
To filter all traffic and locate POST data, type in the following in the filter section
http.request.method == “POST”
See screenshot below. It is showing 1 POST event.



tep 3: Analyze POST data for username and password
Now right click on that line and select Follow TCP Steam



This will open a new Window that contains something like this:



So in this case,
username: sampleuser
password: e4b7c855be6e3d4307b8d6ba4cd4ab91
But hold on, e4b7c855be6e3d4307b8d6ba4cd4ab91 can’t be a real password. It must be a hash value.
to crack this password its simple just open new terminal window and type this :



and its looks like this:
  1. username: sampleuser
  2. password: e4b7c855be6e3d4307b8d6ba4cd4ab91:simplepassword

You Have Done... :)

3 Ways to Root Android 7.0 Nougat on Nexus Running Official AOSP [Update: Root Android 7.1]

3 Ways to Root Android 7.0 Nougat on Nexus Running Official AOSP [Update: Root Android 7.1] If you own a Nexus phone then chances are you have already updated your device with the latest official Android 7.0 Nougat firmware. This brings the newer firmware build number NRD90M to the Nexus range including the Nexus 5X, 6P, 9, 6, Nexus Player, and the Pixel C. Unfortunately, Nexus 5 and 7 were left behind.

Hence, to be ready, you may need to be rooted and also setup a custom recovery like TWRP on your device. So that once the CM 14 bas
