Wireshark achieves this by putting the network interface card (NIC) into promiscuous mode, allowing it to capture all packets on the network, regardless of their destination.
When a user logs into a website or any other online service, their login credentials are typically transmitted over the network in plain text or encrypted form. Wireshark can capture these packets and display their contents, allowing the user to see the login credentials in clear text. This can be done by applying filters to the captured packets, focusing only on the relevant traffic.
To capture login credentials using Wireshark, the first step is to select the appropriate network interface to capture packets from. This can be done by going to the "Capture" menu and choosing the desired interface. Once the capture is started, Wireshark will begin capturing packets from the selected interface.
To filter the captured packets and focus only on login credentials, Wireshark provides a wide range of display filters. These filters allow users to specify the criteria for the packets they want to see. For example, a filter can be set to display only packets containing the HTTP protocol, which is commonly used for transmitting login credentials.
Once the appropriate filters are applied, Wireshark will display the captured packets that match the specified criteria. By examining the contents of these packets, users can easily identify login credentials and passwords. This can be particularly useful for security testing, as it allows testers to identify vulnerabilities in the login process and assess the strength of the authentication mechanism.
However, it is important to note that capturing login credentials using Wireshark may raise ethical and legal concerns. In many jurisdictions, intercepting and analyzing network traffic without proper authorization is illegal. Therefore, it is crucial to obtain the necessary permissions and follow ethical guidelines when using Wireshark for capturing login credentials.
In conclusion, Wireshark's sniffing capabilities make it a valuable tool for capturing login credentials and passwords. By putting the network interface card into promiscuous mode and applying appropriate filters, users can easily identify and analyze packets containing login credentials. However, it is essential to ensure that the use of Wireshark complies with legal and ethical standards.
