Explore the persistent security vulnerabilities and attack vectors associated with NTLM (NT LAN Manager) authentication protocol in this 36-minute conference talk by Marina Bochenkova. Delve into the legacy authentication system's inherent weaknesses and discover how attackers continue to exploit NTLM despite its known flaws. Learn about modern attack techniques targeting NTLM implementations, understand the challenges organizations face when trying to migrate away from this outdated protocol, and examine real-world scenarios where NTLM vulnerabilities have been successfully exploited. Gain insights into defensive strategies, mitigation techniques, and best practices for securing environments that still rely on NTLM authentication while working toward more secure alternatives.
