Bypassing Security Controls in Mobile Networks from a Red Team Perspective
Ali Abdollahi analyzes cellular core network security mechanisms, reviewing IMSI catchers, diameter routing flaws, and protocol bypasses from a red team perspective.
Summary
The Expanding Core Architecture of Mobile Networks
Modern 4G LTE and 5G mobile networks implement complex cryptographic handshakes and mutual authentication protocols to secure subscriber traffic.
Analyzing Telecom Protocols and Signaling Boundaries
Ali Abdollahi investigates signaling protocols (SS7, Diameter, GTP), identifying how perimeter interconnection nodes leak location telemetry and subscriber identifiers.
Simulating Cellular Attacks and Perimeter Bypasses
The author demonstrates practical adversary techniques—including rogue base station interaction, IMSI harvesting, and data interception across unencrypted backhaul links.
Carrier Hardening and Telemetry Monitoring
The presentation provides telecom operators with recommendations for deploying signaling firewalls, protocol sanitization, and subscriber privacy enhancements.
