Description
Seungjoon Na and Hwankuk Kim present a security testing method in 2026 for 5G network cores. As 5G gear becomes open and software-based, flaws in the protocol that links radio towers to the core could let attackers in. Their method fuzzes the equipment, feeding it warped messages to see how it reacts.
What sets the method apart is that it tracks the connection state first, following the official rules to reach the right state before striking. They ran over twelve hundred attack scenarios against four open-source 5G cores. They found thirty-two breaks from the official behavior, including eleven security flaws. No core crashed. The team says state-aware testing is a must for this protocol.
