Can Wireshark Capture Passwords?

Wireshark is a powerful network protocol analyzer that allows you to capture and interactively browse the traffic running on a computer network. One common question that arises among users is whether Wireshark can capture passwords.

The short answer is yes, Wireshark has the capability to capture passwords that are transmitted in plain text over a network. This includes passwords sent over unencrypted protocols such as HTTP, FTP, Telnet, and more. When capturing network traffic, Wireshark can intercept and display these passwords in clear text.

However, it's important to note that capturing passwords in this manner is a significant security risk. If sensitive information like passwords is sent over a network without encryption, any attacker with access to the network traffic can easily intercept and view this data using tools like Wireshark.

To protect your passwords and sensitive data from being captured by Wireshark or other similar tools, it's crucial to use secure protocols like HTTPS, SFTP, SSH, and enable encryption wherever possible. Additionally, using strong, unique passwords and implementing two-factor authentication can add an extra layer of security to prevent unauthorized access even if passwords are intercepted.

Remember, while Wireshark can capture passwords, it's ultimately up to users and network administrators to prioritize security and take proactive measures to safeguard their sensitive information.
