OSINT: What does the Internet or the Darknet know about your company?
In today’s networked world, it is astonishing how much information about companies and private individuals is accessible on the Internet. This publicly available data can be found both on the clear web and on the darknet. This is where OSINT, short for Open Source Intelligence, comes into play. OSINT is used by cyber criminals to systematically collect information and scout out potential targets for their attacks.
What is Open Source Intelligence, OSINT?
Open Source Intelligence (OSINT) refers to the collection and analysis of information from freely accessible sources on the internet. This includes websites, social networks, forums and the darknet. Cybercriminals use OSINT to collect contact details, IP addresses, technological information and other sensitive data about companies or individuals. This data is then structured and analysed to obtain a comprehensive picture of the target.
How do cybercriminals use OSINT?
Cyber criminals use OSINT to plan and carry out their attacks. They search specifically for information that can help them in their endeavours. With the help of special OSINT tools, they can carry out extensive research work automatically. These tools search the internet for relevant data and compile it in a clearly organised manner.
Dangers due to OSINT
The information obtained through OSINT can form the basis for further cyber attacks. A common scenario is a social engineering attack, in which attackers attempt to obtain confidential information through targeted manipulation and deception. For example, they could pretend to be an employee of a company and find out more details by asking specific questions.
Protective measures against OSINT attacks
Companies should be aware of the danger posed by OSINT and take appropriate protective measures. This includes regularly checking their own online presence for sensitive information. Another important step is to sensitise employees to the dangers of social engineering and train them in the secure handling of company data. Here are 6 tips to protect yourself from OSINT attacks.
6 tips for companies to protect themselves against Osint attacks:
1. sensitisation and training of employees
A fundamental step in protecting against data misuse is the sensitisation and continuous training of employees. This training should aim to raise awareness of the dangers of data misuse and teach best practices for handling sensitive information. Employees should be able to recognise potential security threats and react accordingly. A security culture that embeds OSINT and data security as core values is essential.
2. implementation of robust security policies
Organisations should develop and implement robust security policies. These policies must clearly define what information may be made public and what information must be kept confidential. This includes implementing access controls and regularly reviewing security protocols. By implementing data classification and handling policies, organisations can ensure that sensitive data is adequately protected.
3. use of encryption technologies
Encryption technologies are essential for the protection of sensitive data. By using strong encryption methods, organisations can ensure that data remains unreadable even in the event of a security incident. It is important to use encryption for both data at rest and data in motion to ensure the highest level of security.
4. continuous monitoring and threat analysis
Continuously monitoring and analysing threats is crucial to identify potential security risks at an early stage. Companies should use specialised security solutions and OSINT tools that are able to identify and report suspicious activity. By proactively analysing threat intelligence, companies can identify and close security gaps before they can be exploited.
5. use of OSINT for vulnerability analysis
Organisations can also use OSINT tools to identify and mitigate their own vulnerabilities. Regular self-audits and OSINT analyses make it possible to collect publicly available information about the company and assess potential risks. On this basis, targeted measures can be taken to protect or remove critical information.

Glossary of OSINT (Open Source Intelligence)
- OSINT (Open Source Intelligence)OSINT refers to the collection and analysis of information available from public sources on the internet. This includes websites, social media platforms, forums, blogs and the darknet. This information is used to gain valuable insights into a target, whether for business or security purposes.
- Dark web: The dark web is a hidden area of the internet that is not accessible through conventional search engines. It is often used for anonymous communication and activities. OSINT analyses may also include the dark web to find out if confidential information about a company or person is being distributed there.
- Social engineering: Social engineering refers to a manipulative technique in which cybercriminals attempt to deceive people in order to obtain sensitive information. OSINT helps identify potential targets for social engineering attacks by collecting publicly available data about people or companies.
- Encryption: Encryption technologies are methods of securing data by transforming the information in such a way that it can only be read again using a specific key. They are an important protective mechanism against the misuse of data that could be obtained through OSINT.
- Threat intelligence (threat analysis): Threat analysis involves identifying and assessing potential risks to protect vulnerabilities. OSINT can be used to collect threat data from publicly available sources and proactively identify security vulnerabilities.
- Access controls: Access controls are security mechanisms that regulate access to data and systems. They help to ensure that only authorised persons have access to sensitive information. They are an important part of security policies to protect data that could be obtained through OSINT analysis.
- Social media: Social media refers to platforms such as Facebook, LinkedIn, Twitter or Instagram where individuals and companies share information. These platforms are an important source for OSINT because they make it possible to collect personal data, business activities or even security-related information.
- OSINT tools: OSINT tools are specialised software solutions used to search and analyse publicly available data. These tools facilitate the collection and evaluation of information from various sources and often offer automated functions to efficiently carry out large-scale research.
- Data classification: Data classification refers to the process of categorising information according to its sensitivity. In companies, data is often categorised into levels such as ‘public’, ‘internal’ or ‘confidential’. This helps to ensure that sensitive data is protected from unauthorised access and to prevent potential OSINT attacks.
- IP address: An IP address is a unique identifier for a device on a network, such as a computer or smartphone. Cybercriminals can use OSINT to determine the IP address of a company or individual in order to launch targeted attacks.
- Compromised data: Compromised data is information that has fallen into unauthorised hands due to security breaches or attacks. OSINT can be used to find out whether sensitive company or personal data has already been published or offered for sale on the internet, especially on the darknet.
- OSINT analysis: OSINT analysis involves the process of collecting, organising and evaluating information from open sources to identify potential threats or gain business insights. It can be carried out in a variety of ways, from manual research to the use of specialised automation tools.
- Cyber security: Cyber security refers to the protection of systems, networks and data from digital attacks, theft or destruction. By applying OSINT, companies can identify potential security vulnerabilities and better protect themselves against attacks.
- PhishingPhishing is a method in which cybercriminals attempt to steal sensitive information such as passwords or credit card details by using fake messages (e.g. emails). OSINT can be used to find out if and how such attacks have been or are being carried out against a company.
- Security awareness refers to the awareness of security risks that companies and employees must develop in order to protect themselves from threats such as social engineering or OSINT-based attacks. This is achieved through regular training and awareness-raising on cyber threats.
Conclusion:
OSINT offers both opportunities and risks for companies. It is therefore important to be aware of the dangers that can arise from publicly available information. Through a well-founded OSINT analysis, companies can identify their own vulnerabilities and proactively protect themselves from potential attacks.
