APT (Advanced Persistent Threat)
A sophisticated, targeted cyber attack campaign conducted by skilled threat actors (often state-sponsored or well-funded criminal groups). APTs targeting carrier infrastructure can compromise network integrity, intercept communications, and steal data.

APT in context
Telecom threats range from opportunistic SMS phishing and SIM swap to nation-state grade location tracking and lawful-interception abuse. The common thread is that most attacks exploit the inherited trust model of legacy signaling. SS7 and Diameter were designed for a closed operator community that no longer exists.
To place APT in the wider telecom-security picture, review A5/2, Anomaly Detection, Artificial Traffic Inflation, Attack Surface Mapping, Backhaul and Cell Phone (Mobile Phone).
