Can Wireshark Sniff Wifi Password

Feb 12, 2015  Subscribe! - In this beginner tutorial, I demonstrate capturing packets with Wireshark. Protocols that are analyzed are Telnet, SSH, FTP,.

Wireless networks are convenient and popular, but poor configuration and encryption leave them open to attack. Hackers can use Wi-Fi vulnerabilities to infiltrate your entire network. Security professionals need to know how to detect, prevent, and counter these kinds of attacks using the latest tools and techniques—the subject of this course with cybersecurity expert Malcolm Shore. Malcolm covers everything from configuring basic security to understanding how hackers extract passwords, harvest connections at rogue access point, and attack networks via Bluetooth. He also explains how to select the right antennae for testing and introduces some sophisticated Windows and Linux tools to scan for vulnerabilities, including Acrylic, Ekahau, and Wireshark.

By the end of the course, you should be able to shore up your wireless connections and gain confidence that your local network is safe to use. Note: This course is part of our test prep series for the Certified Ethical Hacker exam. Review the complete exam objectives at.

I'll demonstrate this using Wireshark in Kali. The first thing I need to do is set the adapter into monitoring mode. We're in monitor mode now. So let's start Wireshark. The first screen of Wireshark displays any prior sessions in which packets were captured, and the list of adapters from which to choose for this capture session. There's a moving packet trace by each interface.

So that's a good guide as to which interface is active. The interface we're interested in is the monitoring mode adapter on wlan0mon. I'll select this and press the blue shark fin to start capturing. While this is running, I'll connect my mobile to the network and use it to switch the WeMo power switch on and off. I'll stop the capture now and we can take a look at what we've captured. The first thing to check is the wireless LAN summary.

There's a question very similar to this already, but not quite an exact duplicate. That said, the answer I've given there applies fairly well here. So, I'll just cut-and-paste: On any Wi-Fi network - encrypted or not, given today's Wi-Fi encryption protocols - any sufficiently skilled and equipped user of the network (and especially the network administrator) could easily access any data you transmit or receive via cleartext protocols. This includes usernames and passwords as well as web pages, documents, and other data sent or obtained via http, ftp, telnet, etc.

WEP security adds a slight barrier, but is still easily decipherable by even unauthenticated users. WPA and WPA2 require a good bit more computational power for outsiders to crack, and much more time. For these, an attacker would most likely monitor traffic for awhile and then take the data home for offline cracking. As with just about any cryptography, brute force will always win if given enough time. With WPA and WPA2, that just means a lot of time. There are side-channel attacks to WPA and WPA2 though.
