QR Code OSINT (Open Source Intelligence) involves gathering information using QR codes to extract hidden or useful data. Here’s how you can dive into QR code OSINT in a fun and informative way
1. Capturing the QR Code
First, you'll need a QR code image or physical QR code to analyze:
Use your smartphone’s camera or a screenshot tool to capture the QR code image.
If the QR code is on a website, right-click and save the image, or take a screenshot.
2. Decoding the QR Code
Now, decode the content hidden in the QR code using a decoding tool:
Online Tools: Websites like ZXing Decoder or QR Stuff let you upload the QR code image to reveal the hidden content.
Command Line Tool: Use zbarimg (a command-line tool) to decode QR codes.
bash
Copy code
zbarimg my_qrcode.png
Mobile Apps: Apps like QR Droid or QR Code Reader are great for quick analysis on mobile devices.
3. Analyzing the Decoded Information
The decoded content might be a URL, plain text, contact details, or other embedded data:
If it’s a URL:
Copy the URL and check it with VirusTotal to see if it’s safe.
Use a URL expander like CheckShortURL if it’s a shortened link to see the final destination.
Run the URL through Whois Lookup (e.g., who.is) to get details about the domain owner, registration date, and more.
If it’s plain text or a message:
Look for any hidden patterns, codes, or contact information.
Google any suspicious content to check if it’s associated with known scams or phishing attempts.
4. Investigating Metadata and Tracking Information
If the QR code directs to a URL:
Browser Inspection: Use your browser’s developer tools (F12) to inspect the network traffic when you visit the URL. Look for additional data being loaded, redirects, or third-party requests.
Intercept Traffic: Tools like Burp Suite or Fiddler can be set up to intercept and inspect the HTTP requests, allowing you to see the data exchanges with the server.
Look for Tracking Parameters: Analyze the URL for parameters that might indicate tracking or targeting (like UTM codes).
5. Checking for Social Engineering or Phishing Campaigns
Reverse Image Search: If you suspect a QR code is being used in a campaign, perform a reverse image search using Google Images or Tineye to see if similar QR codes are used elsewhere.
Compare Content: Check if the QR code content matches known phishing attempts or suspicious domains listed in databases like OpenPhish or Phishtank.
6. Extracting Information from QR Code Images
If the QR code is an image file:
Use EXIF Tool (exiftool) to check for metadata in the image. Sometimes, QR code images might include extra data about the source or creation date.
bash
Copy code
exiftool my_qrcode.png
7. Investigating for Geolocation Data
If the QR code contains GPS coordinates or a location URL (e.g., Google Maps):
Copy the coordinates into Google Maps or OpenStreetMap to visualize the location.
Check if the coordinates lead to any significant or suspicious places.
8. Aggregating and Correlating Data
If you have multiple QR codes to analyze:
Use Maltego or Spiderfoot to create a visual map of how the data might be connected. These tools allow you to see relationships between different QR codes, domains, and data points.
9. Documenting Findings
Finally, document everything you find:
Take notes on the decoded content, URLs, domains, metadata, and any unusual patterns.
Use tools like CaseFile for visual documentation, making it easier to track connections and findings.
