Network packets become the frontline against rogue AI systems

As enterprises deploy AI agents that operate autonomously across infrastructure—making thousands of decisions per minute without human intervention—traditional perimeter security and access controls are becoming obsolete. The shift moves detection from identity and endpoint layers to packet-level inspection, where organizations can identify shadow AI models making unauthorized API calls, data exfiltration attempts, or anomalous computational patterns before they cascade across systems. This changes how infrastructure software vendors build monitoring and control into their products, creating new categories of network security built around behavioral anomaly detection rather than rule-based blocking.

Security flaw lets attackers downgrade 5G networks to 2G speeds

Source: The Register: Biting the hand that feeds

Researchers discovered that legitimate SIM card functionality built into telecommunications standards can be weaponized to hijack modems, execute arbitrary code, and force devices back to obsolete 2G protocols. The vulnerability exists across billions of deployed devices and can't be patched without industry-wide coordination. Backwards-compatibility features that keep legacy networks running also create attack surfaces, and telecom standards bodies move too slowly to close gaps that determined adversaries can exploit at the hardware level.
