Securing Telecom Networks
From Core to Edge.
Mobile operators, ISPs, and network infrastructure providers face threats unique to the signalling plane — SS7 abuse, SIM swap fraud, GTP tunnel attacks, and insider access to subscriber data. DKTrace is built for telecom SOC teams.
Threat Landscape
Telecom-Specific Cyber Threats
SS7 / Diameter Protocol Abuse
Attackers exploit weaknesses in core signalling protocols to intercept calls, track subscriber locations, and redirect SMS — including 2FA codes. DKTrace's telco-monitor detects anomalous MAP and Diameter messages in real time.
SIM Swap Fraud
SIM swap attacks redirect victims' phone numbers to attacker-controlled SIMs — enabling account takeover and financial fraud. DKTrace correlates UpdateLocation messages with banking fraud signals for immediate alerting.
Roaming Network Intrusions
IPX/GRX inter-carrier networks are a common attack entry point. DKTrace monitors all roaming interfaces for unexpected signalling traffic, rogue GSMA entities, and data exfiltration via GTP tunnels.
Core Network Insider Threats
Telecom engineers have privileged access to subscriber data, lawful intercept systems, and network configuration. UEBA detects anomalous access patterns — bulk subscriber queries, configuration changes outside maintenance windows.
