Open-source investigations don’t stop at borders. Whether you're tracing fraudsters in Toronto or uncovering shell companies in Southeast Asia, successful international investigations demand more than just curiosity. They require adaptability to varying naming conventions, language barriers, geographic differences, and digital behaviors that show broad differences across cultures.
This guide distills key strategies and regional insights that can help OSINT professionals work smarter when navigating cross-border cases.
Names are the starting point of most investigations. However, when working internationally, assuming the familiar 'first-last' order or treating every part of a name as a surname can lead to false matches. Here's a breakdown of naming practices across different regions:
Note: In many South Asian cultures, women do not commonly adopt their husband's surname after marriage. This is especially true in India, Pakistan, Bangladesh, and Sri Lanka, which may impact marital alias tracking.
Use phonetic matching, multiple alias entries, and a flexible understanding of naming order when working in global contexts. For deeper references, consult resources like the UK Naming Practices Guide or the ROCIC Law Enforcement Guide to International Names.
Important Note for Domestic Investigations:
These strategies are not only crucial for international investigations but also for domestic cases when the subject has ties or origins abroad. Local searches may return results, but searching for name variations could uncover results from another country. Entity resolution processes are essential in these situations, as they help attribute overlapping data, even when names are transliterated differently or formatted according to local conventions.
Geography can obscure data trails. For instance, searching 'Bangalore' instead of 'Bengaluru' could yield very different results on platforms like LinkedIn or Facebook. Cities may also have multiple names or variations that could influence search results. Try searching with variations such as “Querétaro” vs. “Santiago de Querétaro,” “New York City” vs. ”NYC,” or “München” vs. “Munich.”
Understanding local conventions is key. In some cultures, proximity to a landmark or region is more prominent in identity than an exact postal address. This also influences how people list their locations on social media.
Understanding global naming conventions and location variance is crucial for identifying threat actors and fraudulent activities, especially in cases of international terrorism, financial crimes, or counterintelligence. By leveraging accurate and broad data searches, investigators can more effectively mitigate risks to national security.
Languages and scripts, such as Urdu, Pashto, Gujarati, and Vietnamese, present both challenges and opportunities. Transliteration differences can often fragment search results, particularly when individuals from rural areas have names phonetically translated from national ID cards. In languages without standardized keyboards (like Pashto), names may be entered in more widely available scripts like Arabic or Latin. Names like 'Muhammad' may be used as honorifics rather than day-to-day and may be omitted in common aliases. To tackle this, check the language of public posts or profiles, knowing that a Farsi speaker’s name might be transliterated differently than someone using Roman script.
If you encounter a name that seems unfamiliar, consider checking the language used in their public posts or profiles to identify likely regional ties. For example, a Farsi speaker's name might be transliterated into Roman script many different ways in Persian-speaking regions.
Be mindful of transliteration variance: the same name might appear hyphenated, combined, or spaced differently depending on the platform or country. For example, the name "Sal-ud-din" could be written as "Saluddin," "Sal ad Din," or "Salahuddin."
When in doubt, use linguistic logic and behavioral pattern recognition: if someone’s name includes “son of,” try using association search features to look for relatives. Understand religious or caste-based naming as both an identifier and a potential source of noise.
Thinking globally will hugely improve your international investigations, but only if you remember to:
Effective keyword searches are feedback loops that evolve during your investigations. As you learn more about your subject, finding insights related to hobbies, affiliations, and social handles, update your terms accordingly to refine searches. For example, knowing your subject plays online poker or speaks Farsi lets you scan niche platforms and forums more effectively, improving the quality of your results.
Every international case is a puzzle of local nuance. The more investigators train themselves to think like global citizens—shifting between naming logic, language patterns, and cultural context—the more precise their investigations become. Each case offers an opportunity to deepen your understanding of the world, as your effectiveness as an OSINT professional grows with every unfamiliar name you decode and unexpected data trail you follow to its source.
