Maltego
Overview
Maltego is a commercial OSINT and link-analysis platform that visualizes relationships between people, organizations, domains, IP addresses, networks, and social media. It uses “transforms” to pull data from dozens of sources and maps them into an interactive graph.

Key Concepts
- Entity — Any node in the graph (domain, email, person, IP, phone, etc.)
- Transform — A query that expands an entity using an external data source
- Graph — The visual map of all relationships discovered
- Transform Hub — Marketplace for third-party data integrations
Common Use Cases
- Map all subdomains and IPs for a target domain
- Discover email addresses linked to an organization
- Find social media accounts tied to a username or email
- Visualize relationships between companies and individuals
- Trace infrastructure connections between domains
Workflow Example
Start with: Target domain (e.g., example.com)
→ Run "To IP Address" transform
→ Run "To DNS Name" on each IP
→ Run "To Email Address" on discovered domains
→ Build out email/person/org graph
Useful Transforms
To IP Address [DNS]— Resolve domain to IPTo DNS Name— Reverse DNS lookupTo Email Address [PGP]— Find emails via PGP keyserversShodan— Enrich IPs with Shodan dataHaveIBeenPwned— Check email breach exposureVirusTotal— Threat intelligence on domains/IPs
OPSEC Notes
Transforms query third-party APIs — your queries may be logged. Community edition also sends data through Maltego’s servers. Use Professional/local transforms for sensitive engagements.
