Planning and carrying out an open-source investigation

Part 3 of our special series of articles on using OSINT in journalism. This time, follow our four steps to completing an open-source investigation


Journalists can follow four steps to start their open source investigations: 


Step one: Planning 

Before diving into a story you should first determine if an investigation is possible or needed. To keep an investigative mindset it is important to always start with a series of questions. With your questions in mind, you can then formulate a clear strategy and choose the right tools to search for key information. When it comes to information gathering, journalists can decide either to make contact with the target during the investigation or to remain distant from the target and thus have a lower risk of being detected. 

Get started by answering the following questions: 

1: What has prompted the need for the investigation? 

2: What are the key questions that need to be answered? 

3: Which tools and platforms can help gather the required information?

Search techniques

● Incorporate social media data to cross-reference your findings. Pay particular attention to who was the original source of this information, when this information was posted and where this information was posted from. 

● Do a reverse image search using TinEye or Google Images. A reverse image search allows you to upload an image and immediately see when and where this image was first used across the web. 

● Use other platforms like WeVerify, to fact-check videos and images online.



Step two: Structure and secure information 

Once you have a plan in place, you can now begin identifying the sources you will be using to collect and archive your data so that it remains secure. It is important not to lose sight of ethical, safety and legal considerations especially when dealing with personal data. Various data privacy laws including the General Data Protection Regulation (GDPR), the California Consumer Privacy Act (CCPA) and many others, exist to govern the collection, use and storage of personal data. 

Always evaluate any potential data storage risks and keep evidence and documentation safe by using encrypted storage. Also, don’t forget to take precautions to ensure your identity remains secure. 


Various groups including the investigative journalism group, Bellingcat; the Global Legal Action Network; and the Syrian Archive among others have created a standard process for archiving and investigating open-source evidence. Collecting, preserving and building a body of evidence can serve as proof of power abuses and human rights violations.



Step three: Verifying your information 

Raw information gathered must be analysed and processed before any useful or actionable conclusions can be drawn. This includes contacting people and verifying findings across multiple sources. Verification is an iterative process that involves three main phases:

Verifying the source - Where did you get the information from? 

Verifying the content - Is the information actually what it claims to be? 

Verifying its relevance - Does this information fit into your investigation?




Geolocation is the process of determining the geographic position of a particular event. This can be done by using tools such as Google Maps or Google Earth to match geographical features seen in the footage you are investigating. You can cross-reference stills from the footage to satellite imagery to confirm whether or not a video was indeed taken from a particular location. In some cases, it is possible to identify the approximate time the footage was captured by analysing the sunlight and shadows. Using SunCalc for example, it is possible to analyse the position of shadows and the sun at any given time and date, at any given location.


Step four: Publishing your findings 

Finally, journalists should publish their findings as well as show the process behind their investigations with the aim of ensuring transparency as well as building trust with the audience. Ensure that your findings are presented across various digital platforms to ensure your story can have the widest available reach.

Why Journalists are Speaking out Against Western Media Bias in Reporting on Israel-Palestine

Over 1500 journalists from various US news organizations have signed an open letter criticizing the Western media's coverage of Israel's actions against Palestinians. They accuse newsrooms of dehumanizing rhetoric, bias, and the use of inflammatory language that reinforces stereotypes, lack of context, misinformation, biased language, and the focus on certain perspectives while diminishing others. They call for more accurate and critical coverage, the use of well-defined terms like "apartheid" and "ethnic cleansing," and the inclusion of Palestinian voices in reporting.
