TALK 2: From voice to influence - How IMS and Telecom Signalling Enable Nation State Disinformation - by Mark O'Sullivan
Disinformation is usually discussed as a "Layer 7" problem—Facebook bots, deepfake videos, and Twitter trolls. But what happens when the attack surface is the network itself?
In this session, we go under the hood of global telecommunications to explore how IMS (IP Multimedia Subsystem) and legacy signaling protocols like SS7 and Diameter are being repurposed as delivery mechanisms for state-sponsored cognitive warfare. While the industry has long focused on tracking and intercept, the new frontier is insertion.
We will break down the mechanics of how nation-states can bypass traditional "Big Tech" content moderation by going directly to the handset. We’ll discuss:
* The Signaling Sandbox: How protocol flaws allow for high-trust impersonation of official entities.
* The IMS Pivot: How the transition to VoLTE/5G introduces new headers that can be spoofed to manipulate the "user experience" of a phone call or text.
* Case Studies in Chaos: Real-world examples where telecom signaling was used to sow civil unrest and bypass the open internet.
By understanding the plumbing of the mobile network, we can better appreciate how the next generation of disinformation won't just be seen on a feed—it will be delivered via the core of the network itself.
