Online devices

Exposed services and device counts from internet-wide scans (Shodan, Censys, Quake, FOFA). Operator uses this to scope target discovery, attribute observed activity, and pre-stage payloads. Refresh against live facets before relying on the numbers.

VPN

Commercial VPN providers with servers (points of presence) inside the country. Operators use these for in-country egress, to appear local to defended infrastructure, or to hop into adjacent jurisdictions. Cross-check provider server lists before relying on the entry; vendors add and drop POPs frequently.

Telecom

Top telecom operators in the country, ranked by subscriber base or revenue. Note state ownership, foreign parents, and the share of the backbone each carrier controls. Operators use this to identify lawful-intercept routing, blocked transit, and the carriers worth pre-staging redirectors against.

Data centers

Commercial data centers and major carrier-neutral facilities inside the country. Operators map these to locate target hosting, hyperscaler regions, peering fabric, and submarine-cable landing proximity. Cross-reference DataCenterMap and Cloudscene before relying on the entry.

Mobiles

Top mobile device makes, models, and types in the country. Operators use this to scope mobile-implant compatibility, plan device-class lures, and predict baseband, OS, and security-patch posture on target. Cross-reference StatCounter, Kantar, and Counterpoint before relying on the entry.

Apps

Mobile and web apps with material user base in the country. Covers messaging, payments, ride-hailing, delivery, banking, government, and ID apps. Operators use this for pretext design, lure infrastructure, implant compatibility, and pattern-of-life inference. Cross-reference Sensor Tower, data.ai, AppMagic, and the country’s app-store top charts.

Keyboards

Standard keyboard layouts the operator encounters on Windows endpoints in the country. KLID is the Windows layout identifier; DLL is the driver shipped with Windows 10/11. Operators use this to predict input behaviour (AZERTY / QWERTY / QWERTZ), build plausible pretexts, and tune implant input handling. Cross- reference kbdlayout.info for full layout maps and dead-key behaviour.
