What is OSINT

Open-source intelligence (OSINT) is a multi-factor (qualitative and quantitative) approach for gathering, evaluating, and making judgments on data available in publicly available sources for use in intelligence. OSINT does not require to hack into systems or use private credentials to access data. Viewing someone’s public profile on social media is OSINT, but using their login details is not.

This reconnaissance phase is vital for an engagement as it provides information that will be used to exploit targets or gain access to data.

“If you know the enemy and know yourself, you need not fear the result of a hundred battles. If you know yourself, but not the enemy, for every victory gained you will also suffer a defeat. If you know neither the enemy nor yourself, you will succumb in every battle.” (Art of war, Sun Tzu)
