Lessons Learned From Public Cybercrime Cases

A dedicated series of OSINT (Open Source Intelligence) case studies has been compiled, using the email addresses and aliases of individuals already publicly charged, convicted, or sanctioned for cybercrime. By taking identifiers published in official documents like court filings, sanctions lists, and investigative reports, the project runs them through email and username lookup tools to see what digital footprint remains on live platforms today, teaching practical investigation techniques.

The studies serve as a transparent educational resource for cybersecurity professionals and investigators, demonstrating how public records can be leveraged to understand an adversary's digital presence. Each case is framed against the established public record, with a strict ethical focus on individuals already named by authorities. The key takeaway is a structured, ethical methodology for building investigative skills directly from real-world, concluded cases.
