DISCLAIMER: This CTF takes you through a real investigative process where you will join a real Telegram group and search a user within it. Please ensure you are comfortable with your operation security before starting. NO DOWNLOADS REQUIRED - NO INTERACTION WITH PEOPLE REQUIRED \ MADE BY EVA PROKOFIEV (EPCYBER) ═════════════════════════════════════════════════════════════════════ BRIEFING ═════════════════════════════════════════════════════════════════════ A user in a Chinese underground Telegram community is promoting what we believe to be illegal gambling services. Their promotional messages appear professional — "quality guaranteed," "after-sales support," "no worries" — suggesting organization rather than opportunistic posting. We believe this operator may have connections to legitimate business infrastructure, potentially using corporate fronts to facilitate underground activity. Your task is to trace their digital footprint and confirm their real-world identity using open source techniques. The investigation begins behind a +86 login wall. A Chinese developer blog contains intelligence on dark web forums, but access is restricted. You will need to find a way through. Objectives: • Bypass content restrictions to identify the dark web forum • Locate the associated Telegram community with that forum • Identify the gambling promoter within the channel • Trace their QQ contact to phone infrastructure • Uncover connections to legitimate business operations • Pivot through archived data to find secondary identifiers • Confirm identity via Chinese social media correlation ═════════════════════════════════════════════════════════════════════
