Dive into a comprehensive analysis of zero-day vulnerabilities discovered in K-12 classroom management software during the COVID-19 pandemic. Explore how four combined vulnerabilities led to a wormable unauthenticated remote code execution with System level privileges, affecting over 9,000 school districts. Learn about the technical dissection of the network protocol, custom Scapy layers, and witness a single-click exploit demonstration. Gain insights into the thought process and technical details of reverse engineering network traffic, as well as the potential impact on both school districts and home devices. Understand the attacker's goals, system architecture, and the steps involved in emulating a teacher to find students and perform handshakes. Discover the road to privilege escalation and its potential consequences in this eye-opening conference talk by Sam Quinn, a Security Researcher from McAfee's Advanced Threat Research team.
