Description: On this episode of HakByte, @Alex Lynd demonstrates how a $5 microcontroller (or a WiFi Nugget) can be used to block WiFi communication, by abusing a flaw in the WiFi protocol that lets hackers send arbitrary deauthentication packets to client devices. Using WireShark & Arduino software, we explore constructing custom WiFi packets, and using them to attack wireless devices. -----☆-----☆-----☆-----☆-----☆-----☆-----☆-----☆-----☆-----☆ Buy a WiFi Nugget: hakcat.com -----☆-----☆-----☆-----☆-----☆-----☆-----☆-----☆-----☆-----☆ Links: HakCat Webstore: Nugget Invader GitHub / Code POC: github.com/HakCat-Tech/Nugget-Invader Alex Lynd's Twitter: twitter.com/alexlynd Alex Lynd's GitHub: github.com/alexlynd -----☆-----☆-----☆-----☆-----☆-----☆-----☆-----☆-----☆-----☆ Chapters: 00:00 Intro @Alex Lynd 00:19 What are Deauth Attacks? 00:39 Attack Implications 00:52 Deauthing w/ Microcontrollers 01:10 Follow Along! 01:25 Analyzing WiFi Packets in Wireshark 02:16 Deauth Packet Structure 04:18 Running a WiFi Scan 04:39 Target Client Devices 05:31 ESP8266 Deauth Packets 08:15 Deauth Attack Demo 08:29 WiFi Nugget Attack Software 08:40 WiFi Nugget Network Invader 09:24 Outro Hak5 -- Cyber Security Education, Inspiration, News & Community since 2005: -----☆-----☆-----☆-----☆-----☆-----☆-----☆-----☆-----☆-----☆ Our Site → hak5.org Shop → hakshop.myshopify.com Subscribe → youtube.com/user/Hak5Darren?sub_confirmation=1 Support → patreon.com/threatwire Contact Us → twitter.com/hak5 Threat Wire RSS → shannonmorse.podbean.com/feed Threat Wire iTunes → itunes.apple.com/us/podcast/threat-wire/id1197048999 -----☆-----☆-----☆-----☆-----☆-----☆-----☆-----☆-----☆-----☆ ____________________________________________ Founded in 2005, Hak5's mission is to advance the InfoSec industry.
