Imagine a cybersecurity attack in an organization. What is the first step in such a situation?
It is to gather intelligence on the target. This intelligence gathering is the primary step for red team activity or penetration testing. Information scraping from different sources comes under OSINT.
This article explores the power of open-source intelligence in detail. We’ll provide a quick overview of its history, differences from other information sources, uses, framework, tools, best practices, and others.
It refers to the legal process of gathering information about an organization or a person from public and accessible sources. This information aims to answer a specific intelligence question. It covers the information present on the internet, books or reports in public libraries, press release statements, or newspaper articles.
The different types of information gathered from these sources in OSINT cover conferences, public speeches, webinars, videos, information in images, or general text-based content.
The essential two parts of this information intelligence are passive and active. Passive open-source collection refers to collecting information about a specific target using publicly available information. Hence, there is no communication or engagement with online individuals, such as following, friending, messaging, or commenting. It has a reduced risk of attribution.
Active open-source intelligence refers to constant engagement and is often considered an undercover operation for businesses. Here, the target is added as a friend on social media, and the actions include messaging, commenting, and liking the target’s posts. It may require special permission and have a high attribution risk.
The roots of OSINT lie in the intelligence activities conducted by the military and intelligence community. Earlier, information gathering was conducted through human sources (HUMINT) or electronic signals (SIGINT).
In the 1980s, open-source intelligence was added to gather intelligence. Slowly, security agencies started focusing on information collection to stay ahead of hackers.
The present use of this powerful intelligence focuses on intelligence gathering along with regular penetration testing. This helps reduce potential organizational risk before an attacker exploits the threat.
Open-source intelligence is different from other information sources in the following ways:
The use of machine learning, natural language processing, and other analytical techniques are characteristic of OSINT. The other information sources focus on human analysis and interpretation.
It involves information gathering from different sources like government reports, public records, news articles, and social media. The other information sources focus on specific sources only.
It collects information that is publicly and legally available only. The other information sources obtain data from classified or confidential sources.
When looking to understand the uses of open-source intelligence, it is essential to focus on its use by defenders and hackers. Here are the essential uses for both:
Defenders, security teams, and penetration testers use OSINT to reveal public information about internal assets and other information outside the organization. Some helpful sources include leaked company information, IP addresses, configurations, unpatched software, and open ports.
Defenders get a chance to manage the information outside the organization. It covers social media content and vast amounts of relevant information. Company acquisition may result in the public availability of company information publicly. Further, the vendors and partners may share specific company IT details.
When it comes to hackers, it is easy for them to retrieve professional and personal information about employees on social networking sites. Employees with privileged access to company sources are the centre of the target for phishing attacks. LinkedIn is the right source if asked for the best network for gaining information from hackers, as it contains job titles and company structure details.
Hackers can use open-source intelligence for retrieving credentials, leaked information, unpatched assets, misconfigured cloud data stores, or open ports. Attackers get a chance to identify the embedded passwords and encryption keys in the developers’ codes who are not conscious of the security concerns in coding.
