MLD Considered Harmful - Breaking Another IPv6 Subprotocol

Explore the potential security vulnerabilities of Multicast Listener Discovery (MLD) and MLDv2 protocols in IPv6 networks. Delve into how these protocols, essential for discovering multicast listeners on directly attached links, can be exploited for network scanning, OS fingerprinting, amplified DoS attacks, and router resource consumption. Witness a live demonstration of an attack disrupting multicasting communication using MLD messages. Learn about specific security mitigation techniques to defend against these threats and enhance the security of IPv6 networks in this hour-long Black Hat conference talk by Antonios Atlasis, Jayson Salazar, and Rafael Schaefer.
