The Birdman - Hacking Cospas-Sarsat Satellites

Explore the vulnerabilities in satellite-based communication systems, particularly the International Cospas-Sarsat Programme (ICSP), in this 43-minute conference talk from the Hack In The Box Security Conference. Dive into the challenges of securing legacy space communication technology used by seagoing vessels and aircraft. Learn about the comprehensive investigation conducted on the Global Satellite-based Rescue System, which involves 67 satellites and impacts rescue operations worldwide. Discover how self-built satellite receivers and transmitters were used to uncover serious vulnerabilities in the ICSP's communication and control protocols. Gain insights into the working principles of ICSP and its role in real rescue operations. Witness demonstrations of eavesdropping and spoofing techniques on the communications link between ICSP satellites and ground stations. Examine active attack techniques that exploit unique properties of ICSP satellite networks. Consider proposed solutions to mitigate these security risks, while understanding the complexities of upgrading a system involving over 40 nations and agencies.
