DEF CON
DEF CON (also written as DEFCON, Defcon or DC) is a hacker convention held annually in Las Vegas, Nevada. The first DEF CON took place in June 1993 and today many attendees at DEF CON include computer security professionals, journalists, lawyers, federal government employees, security researchers, students, and hackers with a general interest in software, computer architecture, hardware modification, conference badges, and anything else that can be "hacked". The event consists of several tracks of speakers about computer- and hacking-related subjects, as well as cyber-security challenges and competitions (known as hacking wargames). Contests held during the event are extremely varied and can range from creating the longest Wi-Fi connection to finding the most effective way to cool a beer in the Nevada heat.[2]

Defeating magic by magic：Using ALPC security features to compromise RPC services
Aug 9, 2024·45m
Advanced Local Procedure Call (ALPC) is a Windows kernel Inter Process Communication method, which has recently seen numerous vulnerabilities related to TOCTOU file operations and memory corruption. Despite Windows' security measures, we identified a flaw in the ALPC security mechanism that allowed unauthorized users to gain system privileges. In this talk, we will overview ALPC and RPC communication mechanisms, including the marshal/unmarshal process and kernel security in ALPC syscalls. We’ll analyze historical bugs, detail the vulnerability we discovered, and demonstrate exploitation methods. Finally, we’ll share insights on this attack surface and offer tips on finding similar bugs
