L

Leak Detection
Identifying and investigating data that has been leaked or exposed online.

Link Analysis
Examining relationships between entities, such as URLs, individuals, or organizations, to uncover networks.

Lateral Movement
Techniques used by attackers to move within a network after gaining access, a concept analyzed in cybersecurity OSINT.

M

Metadata
Data that provides information about other data, such as timestamps or geotags in photos, frequently analyzed in OSINT.

Machine Learning
Algorithms and models that allow systems to identify patterns and make decisions, increasingly used in OSINT tools.
