OSINT EP05: Images, Geolocation & Metadata
OSINT EP05: Images, Geolocation & Metadata
They say a picture is worth a thousand words. In OSINT, a picture is worth a thousand data points. This episode focuses on IMINT (Imagery Intelligence) and GEOINT (Geospatial Intelligence).
1. Reverse Image Search (RIS)
Don’t just look at the image; look for where else it exists.
Different search engines have different “brains.” You must use the right one for the job.
- Google Images: The jack-of-all-trades. Good for identifying general contexts, but often censors facial search.
- Yandex Images: The heavy hitter. Unbelievably good at face matching, background landmark detection, and OCR (reading text on billboards in the background).
- Bing Visual Search: Excellent for Object Detection. If you need to identify a specific brand of sunglasses or a car model, use Bing.
- TinEye: The “Exact Match” king. Perfect for seeing if an image is original or a stock photo/repost.
Browser Extensions:
- Search By Image: Adds a context menu to right-click any image and search across all these engines simultaneously.
2. Facial Recognition OSINT
Finding people, not just pictures.
- Search4Faces: Specialized for VK/Russian databases, but surprisingly effective globally.
- PimEyes: The most powerful commercial face search. Paid, but highly effective.
- FaceCheck.id: A strong alternative.
Pro Tip: Bypassing Paywalls/Blur Sometimes services like FaceCheck show a match but blur the source.
- Inspect Element (
F12) on the blurred image.- Look for the image source URL. It might be a Base64 string (
data:image/webp:base64...).- Copy the string and use a Base64 decoder. Sometimes the source URL is hidden within the metadata of that string.
3. Metadata (EXIF Data)
Every digital photo has a “fingerprint” unless it has been scrubbed.
- What to look for: GPS Coordinates, Device Model (iPhone 14 Pro), Date/Time original.
- Note: Social media (FB, Insta, Twitter) strips this data. You need original files (uploaded to blogs, forums, or sent via document mode).
- Tools:
- ExifTool: Command line powerhouse.
- Exif Viewer (Firefox Add-on)
4. Geolocation Tools
Where in the world is this?
AI Assistance:
- GeoSpy.ai: An AI model trained to guess locations based on vegetation, architecture, and lighting.
Mapping Powerhouses:
- Google Maps: Street view is essential. Don’t forget the “Time Machine” feature in Street View to see how a building changed over years.
- Yandex Maps: Excellent for Eastern Europe/Russia. Has unique “Pedestrian” and “heatmap” views.
- Mappls: The best detailed maps for India.
- DualMaps: Splits your screen into Street View, Aerial View, and Map View simultaneously.
Street Level Alternatives: If Google didn’t drive there, someone else might have.
5. Manual Geolocation Tips
- Look for text: Store signs, billboards, license plates. Translate them immediately.
- The Sun: Check shadows to determine cardinal direction (North/South).
- Cross-Reference: If the target’s friend tagged them in a coffee shop, but the target didn’t check in… verify the coffee shop’s interior photos on Google Maps Reviews.
- Gamify Learning: Play GeoGuessr to train your brain to recognize soil, bollards, and electric poles.
