Telegram operates as a primary distribution channel for cyber threat actors. Investigating open groups and broadcast channels yields real-time intelligence regarding ongoing cyber incidents.
Core Investigative Techniques
- Extract permanent numeric peer IDs rather than relying on mutable usernames.
- Analyze forward headers to construct relational propagation trees across illicit channels.
- Correlate cross-group membership records to uncover operational aliases.
