Sessions
Many 5G networks are built in fundamentally new ways, opening new hacking avenues.
Mobile networks have so far been monolithic systems from big vendors. Networks are rapidly changing to an "open" model that mixes software from specialized vendors, hosted in cloud environments.
The talk dives into the hacking potential of the technologies needed for these open networks. We illustrate the security challenges with vulnerabilities we found in real-world networks.
