An OSINT investigation typically starts with a specific research objective in mind. This could be gathering background details on an individual, learning more about a company’s operations, tracking down cybercriminals, or digging up records related to a court case.

The types of public sources leveraged include:

  • Social media sites
  • News articles and public records
  • Corporate records and job sites
  • Satellite imagery
  • Domain name registration data

 

Research objectives can range from the very broad to being highly targeted. An investigation focused on a single person may aim to compile details like:

  • Full legal name and aliases
  • Age and date of birth
  • Current and past addresses
  • Criminal history or court records
  • Assets and finances
  • Education and employment history
  • Contact information
  • Photos
  • Social media profiles and posts
  • Connections to other people and organizations

 

On top of gathering facts, OSINT enables you to uncover relationships between people, organizations, assets, online accounts, and communication channels. Making these connections is crucial for revealing larger patterns and schemes.

 

Conducting Ethical and Legal OSINT Investigations

Whenever you’re gathering intelligence on specific individuals, ethics and legality need to be top priorities.

You should adhere to the following principles:

  • Only access publicly available information that does not require hacking, cracking passwords, or exploiting security holes
  • Avoid making direct contact with investigation targets without their consent
  • Be transparent in your research aims and methods when possible
  • Do not misrepresent yourself or engage in social engineering tactics
  • Respect privacy boundaries and sensitive information that could harm individuals
  • Follow relevant cybercrime and data protection laws in your jurisdiction

 

In particular, be very cautious of not crossing legal lines when investigating people for personal reasons rather than professional inquiries with clear necessity and boundaries.

Document your OSINT process thoroughly in case you ever need to demonstrate the legality and ethics. Having detailed notes also helps with organizing evidence and avoiding getting overwhelmed by the data.

 

Core OSINT Investigation Skills

Mastering a few essential skills will enable you to pursue a wide variety of OSINT investigations effectively:

 

Advanced Search Techniques

Beyond basic Google searching, you need an arsenal of advanced tactics for public record lookups, social media profiling, geospatial analysis, and all types of targeted data mining. Useful approaches include:

  • Crafting search strings with advanced Boolean, proximity, and wildcard operators
  • Filtering by filetype, usage rights, and other parameters
  • Leveraging site-specific syntax for internal tools like intitle: and inurl: on Google
  • Using advanced date filters to surface historical information

 

Link Analysis

Analyzing the connections between data points plays a crucial role in revealing networks and schemes. Tactics like :

  • Tracing an email address or username across platforms to associate accounts with individuals
  • Reviewing who an account follows or friends to identify associates
  • Evaluating metadata from posts and photos to extract geographic locations and devices used

 

Data Analysis and Organization

As the investigation progresses, the amount of information accumulated can quickly become overwhelming. You’ll need to:

  • Record findings in organized notes or case files
  • Create visual diagrams to map connections between people, assets, online activity, etc.
  • Export social media data, domain lookups, and other records for further analysis

 

Verifying Information Authenticity

False positives and misleading data is a constant threat when piecing together information from myriad sources. Get in the habit of:

  • Corroborating facts using multiple trustworthy sources
  • Looking out for fake social media accounts or imposters
  • Inspecting metadata to confirm timestamps and locations

 

With practice, verifying authenticity becomes second nature. Never take anything at initial face value.

 

Staying Anonymous and Secure

You don’t want your target catching wind of an investigation prematurely or, worse, figuring out your identity. Steps like using a VPN, anonymous browsing modes, and disposable devices will ensure anonymity and security.

For investigations related to cybercrime, additional precautions are necessary when engaging with hacking forums, malware samples, and other sketchy sources. Having an isolated virtual machine and burner devices is crucial for protection.
