When conducting threat actor attribution, what type of analysis is used to determine the geographic location of the attacker?

Geographical Information System (GIS) analysis is the formal methodology used to capture, store, analyze, manage, and present spatial or geographic data. In the context of threat actor attribution, GIS techniques are applied to map digital artifacts, such as IP addresses from logs, C2 server locations, or domain registration information, to their physical locations on a map. This process, often referred to as IP geolocation, helps investigators visualize the geographic distribution of an attacker's infrastructure, identify operational hotspots, and infer the potential physical origin of the threat actor or their support systems.

A. Social media analysis focuses on an actor's persona, relationships, and communications, which may incidentally reveal location but is not a geographic analysis technique itself.

C. Malware analysis involves reverse-engineering malicious code to understand its function and indicators, not to determine the attacker's physical location.

D. Linguistic analysis examines language used in code or communications to infer a native language or dialect, suggesting a national or regional origin, not a specific geographic coordinate.

Cyber-Attack Attribution using a Knowledge-Based System and GIS. 2016 18th International Conference on Advanced Communication Technology (ICACT), 658-663. This paper explicitly details a framework using GIS to "identify the geographical location of the cyber-attack source" as a core component of attribution. (DOI: 10.1109/ICACT.2016.7423461, Section III.A).

Cisco Talos regularly publishes threat intelligence reports that include world maps visualizing the geographic origins of spam, malware, and other malicious network activity. This visualization of threat data on a map is a direct application of GIS principles in cybersecurity. (See any Talos report with a "Top 10 locations of observed ..." map, e.g., the weekly Threat Source newsletter).

3. National Center for Geographic Information and Analysis (NCGIA). The NCGIA and other academic bodies define GIS as a system for working with spatial data. Its application in cybersecurity involves taking non-spatial data (like an IP address) and giving it a spatial context for analysis, which is precisely what is required to determine an attacker's geographic location.
