Listen Later

The conversation discusses a recent article about a new attack on a 30-year-old protocol called RADIUS. The protocol is widely used in networks for client-server interactions, including VPN access, DSL and fiber connections, and 5G authentication. The attack, called Blast Radius, exploits vulnerabilities in the MD5 hash used in the protocol. The attack allows adversaries to elicit a response from the Radius server and gain unauthorized access to the network. The conversation highlights the importance of identifying and mitigating the vulnerabilities in the protocol to protect networks.
