What Is FOCA?

FOCA, which stands for Fingerprinting Organizations with Collected Archives, is a free, open-source tool developed by ElevenPaths (a part of Telefónica). It's primarily designed for Windows and focuses on extracting metadata from documents found on websites or public archives. Metadata is the "data about data"—information like who created a file, when it was made, what software was used, and even internal file paths that might reveal network structures.

Originally created to help security researchers fingerprint organizations, FOCA has evolved into a staple for OSINT investigators. It searches for documents like PDFs, Word files, Excel sheets, and PowerPoint presentations on a target domain, downloads them, and then pulls out the metadata. This can reveal surprising details, such as user names, printer information, or even GPS coordinates in images. In 2025, FOCA remains relevant thanks to its GitHub repository, where the community contributes updates and fixes. If you're new to OSINT, FOCA is a great starting point because it's straightforward and doesn't require advanced coding skills.

One of the tool's strengths is its ability to go beyond simple extraction. It can map networks based on metadata, identify vulnerabilities, and even detect open ports or servers. However, remember that FOCA is Windows-only, so if you're on another OS, you might need a virtual machine to run it.

Why Metadata Matters in OSINT

In OSINT, every piece of public information is a potential clue. Metadata is particularly valuable because it's often overlooked by the people who create and share files. For instance, a company might upload a PDF report to their website without realizing it contains the author's username or the company's internal server path.

Metadata can help in various ways:

• Identifying Individuals: Author names, email addresses, or usernames can lead to social media profiles or employee directories.
• Mapping Organizations: File paths might reveal folder structures, software versions, or even printer names, helping build a picture of the internal network.
• Detecting Vulnerabilities: Outdated software versions in metadata can indicate potential security weaknesses.
• Geolocation: Photos or documents with embedded GPS data can pinpoint locations.

Tools like FOCA automate this process, making it faster and more efficient than manual extraction. Without automation, you'd have to download files one by one and use separate tools to pull metadata, which is time-consuming. FOCA streamlines this, allowing investigators to focus on analysis rather than collection.

However, metadata isn't always present or accurate. Some files are "cleaned" before sharing, removing sensitive info. That's why combining FOCA with other OSINT tools is key for comprehensive investigations.

Key Features of FOCA

FOCA packs a punch with features tailored for OSINT enthusiasts. Here's what makes it stand out:

• Document Search and Download: FOCA uses search engines like Google and Bing to find documents on a target domain and downloads them automatically.
• Metadata Extraction: It pulls data from multiple file types, including Office documents (DOC, XLS, PPT), PDFs, and images, revealing authors, dates, software, and more.
• Network Mapping: Using extracted data, FOCA can visualize an organization's network structure, including servers and users.
• Vulnerability Detection: It checks for known issues based on software versions found in metadata.
• Reporting: Generates reports in various formats for easy sharing and analysis.
• Customization: Users can select specific file types or metadata fields to focus on during scans.

These features make FOCA more than just a metadata extractor—it's a full-fledged OSINT companion. For beginners, the graphical interface is intuitive, with options to add projects, search domains, and view results in organized tabs.

In recent updates, FOCA has improved its support for newer file formats and integrated better with other tools, keeping it relevant in 2025's OSINT landscape.

Setting Up FOCA

Getting started with FOCA is simple, especially since it's designed for Windows users. Here's a step-by-step guide to set it up:

• Download FOCA: Head to the official GitHub repository for ElevenPaths/FOCA or the Telefónica website to grab the latest version. It's free, but ensure you're downloading from a trusted source to avoid malware.
• Install the Tool: Run the installer. FOCA requires .NET Framework, which is usually pre-installed on modern Windows systems. If not, download it from Microsoft.
• Launch FOCA: Open the application. You'll see a welcome screen where you can create a new project or open an existing one.
• Configure Settings: Go to the options menu to set up search engines (like Google or Bing) and enable any plugins. You might need API keys for advanced searches, but basic functionality works without them.
• Test a Project: Create a new project, enter a domain (e.g., example.com), and start a search to verify everything is working.

If you're on macOS or Linux, you can run FOCA in a Windows virtual machine using tools like VirtualBox or Parallels. Once set up, FOCA's interface is user-friendly, with tabs for metadata, network maps, and reports.

Pro tip: Always update FOCA to the latest version to benefit from bug fixes and new features, as the tool continues to evolve through community contributions.

How to Use FOCA for Metadata Extraction

Using FOCA is straightforward, even for beginners. Let's break it down into simple steps for extracting metadata from a target domain:

• Create a Project: Open FOCA and select "New Project." Name it and add the target domain (e.g., microsoft.com).
• Search for Documents: In the "Search" tab, choose file types like PDF or DOC. FOCA will use search engines to find documents on the domain.
• Download Files: Select the files from the search results and download them. FOCA handles this automatically.
• Extract Metadata: Switch to the "Metadata" tab. FOCA will scan the downloaded files and display extracted data, such as authors, creation dates, and software versions.
• Analyze Results: Use the "Network" tab to see mapped structures based on metadata, like user names or servers.
• Generate Reports: Export your findings as a report for sharing or further analysis.

For example, if you're investigating a company, FOCA might reveal that a PDF was created usingan outdated version of Adobe Acrobat, indicating a potential vulnerability. Or, it could show internal file paths like "C:\Users\JohnDoe\Documents," giving clues about employee names.

Remember to download only public files and respect privacy laws. FOCA's automation speeds up the process, but always verify results manually for accuracy.

Use Cases in OSINT Investigations

FOCA's metadata extraction capabilities shine in real-world OSINT scenarios. Here are some practical use cases:
