We are going to be using a packet sniffer to collect information from when we browse the internet. This means that the data can be analyzed in hexadecimal, which will reveal any senstive information that was transmitted, such as messages or login credentials. This forces the networking interface to recieve all packets it sees, effectively "sniffing" all of the packets. Open source geeks like myself use open source networking drivers, which allows our interfaces to be switched into promiscuous mode. Windows or Mac OSX: search for wireshark and download the binary. Ubuntu Linux: sudo apt-get install wireshark. However, your network interface will only receive and read packets that contain your host IP address. First step, acquire Wireshark for your operating system. This means that whatever you send over the network can be read by anyone.
Normally, network traffic is transmitted in plaintext. But I've come to realize a lot of you still have no idea why this is so important, so let's go over why.

The answer is undoubtedly yes Wireshark can capture not only passwords, but any type of data passing through a network usernames, email addresses, personal information, pictures, videos, or anything else. In short, with Wireshark you can capture and view data traveling through your network. How does Wireshark find HTTP password Observing the Password in Wireshark Wireshark shows an HTTP packet containing the text. It’s considered one of the most essential network security tools by ethical hackers.
