OSINT for Cybersecurity and Threat Intelligence

Cybersecurity professionals increasingly rely on information from publicly accessible sources to understand emerging threats, investigate suspicious activity and assess an organisation's external exposure. Open Source Intelligence (OSINT) is the structured collection, verification and analysis of information from publicly available sources to produce intelligence relevant to a defined objective. In cybersecurity, OSINT can support threat intelligence, digital footprint analysis, phishing investigations, vulnerability awareness and the identification of potential security risks. However, effective OSINT requires more than finding information online. Analysts must evaluate source reliability, distinguish evidence from assumptions and handle collected information responsibly. This NobleProg hybrid event explores the principles, methodologies and potential applications of OSINT for cybersecurity and threat intelligence. Participants can attend onsite in Andheri East, Mumbai, or join live online, with both attendance options running simultaneously.

Why Attend?Publicly available information can provide valuable context about cyber threats, exposed digital assets and suspicious activity. This event explores how cybersecurity teams can approach OSINT investigations systematically and responsibly. Participants will examine:

• The role of OSINT in cybersecurity and threat intelligence.

• Methods for identifying and evaluating publicly available information sources.

• Techniques for understanding an organisation's external digital footprint.

• Approaches to analysing domains, IP addresses and other cyber indicators.

• How OSINT can support phishing and threat investigations.

• Methods for verifying information and reducing false conclusions.

• Ways to document findings and communicate security intelligence.

• Legal, ethical and privacy considerations in OSINT activities.

Key Topics 1. Introduction to Open Source IntelligenceExplore the foundations of OSINT and its relationship to cybersecurity investigations. Potential topics include:

• What OSINT is and how it is used.

• Publicly available information sources.

• OSINT versus other intelligence disciplines.

• Intelligence requirements and investigation objectives.

• Collection, processing, analysis and reporting.

• Limitations of open-source information.

2. OSINT Methodology and Investigation PlanningUnderstand how structured investigation methods can improve the relevance and reliability of intelligence findings. Explore:

• Defining investigation objectives.

• Identifying appropriate sources.

• Establishing collection boundaries.

• Recording evidence and source details.

• Evaluating information reliability.

• Organising and reporting findings.

3. Digital Footprint and External Exposure AnalysisExamine how publicly available information can reveal aspects of an organisation's internet-facing presence. Potential areas include:

• Domain and DNS information.

• Public IP and infrastructure information.

• Publicly indexed services.

• Website and technology information.

• Publicly exposed organisational information.

• External attack surface awareness. Activities involving organisational assets should be performed within appropriate authorisation and legal boundaries.

4. OSINT for Cyber Threat IntelligenceExplore how open-source information can support the identification and understanding of cyber threats. Potential topics include:

• Threat intelligence sources.

• Indicators of compromise (IOCs).

• Malicious domains and IP reputation.

• Threat actor reporting.

• Malware-related public intelligence.

• Threat trends and contextual analysis.

5. Domain, Website and Infrastructure IntelligenceExamine methods for analysing publicly available technical information associated with domains, websites and network infrastructure. Consider how multiple independent sources can help analysts evaluate potentially suspicious infrastructure.

6. OSINT for Phishing InvestigationsExplore how OSINT can assist in assessing suspected phishing activity. Potential areas include:

• Suspicious domain investigation.

• Website and domain impersonation indicators.

• Public reputation information.

• Infrastructure relationships.

• Evidence verification.

• Reporting suspected phishing activity.

7. Vulnerability and Security Exposure IntelligenceUnderstand how publicly available vulnerability information can support cybersecurity awareness and prioritisation. Potential topics include:

• Public vulnerability databases.

• Security advisories.

• Vendor disclosures.

• Vulnerability severity and context.

• Relating public findings to authorised asset inventories.

• Prioritising further security review.

8. OSINT Tools and Data SourcesExplore categories of tools and information sources that may support OSINT investigations. These may include:

• Search engines and advanced search techniques.

• Domain and DNS information services.

• Public internet infrastructure search services.

• Threat intelligence feeds.

• Public code and document repositories.

• Security advisories and vulnerability databases.

• Information visualisation and analysis tools. Specific commercial or open-source tools will depend on the approved course agenda.

9. Analysing and Validating OSINT FindingsExamine how analysts can distinguish useful intelligence from incomplete, outdated or misleading information. Potential areas include:

• Source credibility.

• Cross-source verification.

• Information freshness.

• False positives.

• Confidence assessments.

• Evidence documentation.

• Analytical bias.

10. OSINT Reporting and Intelligence CommunicationExplore how investigation results can be translated into useful intelligence for security teams and decision-makers. Consider:

• Structuring investigation reports.

• Recording evidence and sources.

• Communicating uncertainty.

• Prioritising find
