Red Team Telecom Threat Matrix
Direct mapping of cellular attack vectors to TelcoSec defensive diagnostics.
ATTACK VECTOR 01
False Base Stations (IMSI-Catchers)
Rogue cellular transceivers (Stingray / Hailstorm / CCoE) forcing 2G/GSM downgrade or capturing unencrypted IMSI/IMEI paging IDs.
🛡️ Mitigated by: TelcoSec Guard (RRC Anomaly Engine)
ATTACK VECTOR 02
Silent SMS (Type-0 PDU Pings)
Zero-display Short Messages sent by surveillance platforms to elicit baseband acknowledgments and extract real-time cell site telemetry.
🛡️ Mitigated by: TelcoSec Guard (PDU Header Filter)
ATTACK VECTOR 03
SIM Toolkit (STK) Applet Exploits
Malicious Over-The-Air (OTA) SMS-PP payloads executing unauthorized proactive commands or exfiltrating SIM hardware crypto keys.
🛡️ Mitigated by: TelcoSec SIM Vault (BIP Command Sandbox)
Available Security Applications
Directly verified and distributed by TelcoSec Mobile Research Lab.
UICC/eSIM hardware applet integrity auditor, STK Bearer Independent Protocol (BIP) command sandbox, and cryptographic key protector.
5G NR Standalone & LTE spectrum auditor, MCC/MNC spoofing triangulator, and False Base Station (FBS) RF heatmap mapper.

Frequently Asked Questions
Common questions about TelcoSec cryptographic distribution & Android security.
How do I verify the repository signing key?
Our official F-Droid release key fingerprint is 146D E2BB FE45 4A0E 8A9D E112 3589 C4DE FA56 8899. It is validated automatically during QR code import or in the Security Policy.
Do TelcoSec apps collect personal telemetry?
No. TelcoSec operates on a strict zero-telemetry policy. Cellular signaling and RF metrics are processed 100% locally on your device with no outbound tracking or analytics.
