Hopefully nobody on the DNM will ever have to consider Hellfire missile strikes as part of their OPSEC, but this article gives a neat insight into how the NSA uses metadata patterns to profile individuals. One could imagine steps that the big players might be taking to avoid such analysis.
Travel Patterns: locations visited in a given timeframe, regular visits to locations of interest.
Behavior-Based Analytics: Low-use / incoming calls only, excessive SIM or handset swapping, frequent detatch / power-down, Courier machine learning models (anyone know what that means?)
Other Enrichments: Travel on particular days of the week, co-travelers, similar travel patterns, common contacts, visits to airports, other countries, overnight trips, permanent move.
