Social Media OSINT¶

Social Media OSINT means gathering intel from social platforms to understand target organizations, employees, tech stacks, and internal operations. For security pros, these platforms are goldmines - they reveal attack vectors, social engineering opportunities, and critical infrastructure details.

Real story: On a recent engagement, I found a senior DevOps engineer at a financial institution posting about AWS migration challenges on Twitter. That led me to exposed S3 buckets with sensitive customer data. Critical finding, $50,000 bounty.

People are the weakest link in security. They share way more online than they realize. By systematically analyzing public social media data, you can uncover:

Employee Information: Names, roles, departments, and contact details
Technology Stack: Programming languages, frameworks, and tools used internally
Infrastructure Details: Cloud providers, hosting platforms, and internal systems
Project Information: Current initiatives, development methodologies, and timelines
Security Practices: Security awareness, policies, and potential vulnerabilities
Organizational Structure: Reporting lines, team compositions, and key personnel

Social Engineering: Detailed employee profiles enable highly targeted attacks
Password Guessing: Personal information helps craft effective password lists
Network Mapping: Technology mentions reveal internal infrastructure
Vulnerability Discovery: Developers often discuss technical challenges publicly
Business Intelligence: Strategic insights for competitive analysis

Statistical Insights¶

87% of employees share work-related information on social media
62% of organizations have experienced data leaks through social media
Average employee reveals 12+ pieces of sensitive information annually
78% of successful social engineering attacks leverage social media intelligence

LinkedIn - The Professional Goldmine¶

LinkedIn is the most valuable platform for gathering organizational intel. This is where you'll spend most of your time.

Key Information to Extract: - Employee names, titles, and departments - Organizational structure and reporting lines - Technology skills and certifications - Project experience and current initiatives - Company size and growth patterns - Hiring trends and job requirements

Advanced LinkedIn Techniques:

# Boolean search operators for precise targeting
