Image OSINT: Finding Clues Hidden in Plain Sight (Part 4)

In the previous post, we discussed Social Media OSINT.

In this one, I’ll share what I’ve been learning about Image OSINT.


What is Image OSINT?

Image OSINT involves extracting intelligence from images to gather information about:

  • people

  • locations

  • activities

  • context

Image OSINT is less about tools and more about observational thinking.

You’ve probably seen this in detective movies — someone zooms into a photo to notice a building in the background, a shop name, a ring on a finger, or unfamiliar people standing nearby.
Those tiny details often tell a bigger story.

What to Look for in an Image

Before touching any tool, look at the image carefully:

  • Background landmarks (buildings, parks, shops)

  • Clothing, accessories, rings (social or cultural hints)

  • Other people in the frame (friends, family, patterns)

  • Time of day, lighting, shadows

Sometimes, just looking closely already gives useful clues.

Tools That Go Beyond Zooming

Some tools can reveal information that the human eye cannot.

Metadata & Forensics

  • ExifTool (Linux): Extract metadata like GPS location, camera model, timestamps

  • FotoForensics: Detect image manipulation and compression artifacts

Reverse Image Search

  • Google Images / Google Lens

  • Yandex Images – excellent for faces (my personal favourite)

  • TinEye – tracks where an image appears online

  • Reverse.photos – requires sign-in

Image OSINT via Social Media

Images behave differently across platforms:

  • Facebook: strips most metadata

  • Instagram: removes most EXIF but keeps some information

  • Twitter/X: heavily compresses images

  • WhatsApp: strips almost all metadata

Profile Picture Analysis

  • Reverse-search profile photos

  • Check if the same image appears on multiple platforms

  • Look for watermarks or cropped versions

Automated OSINT Frameworks

  • Sherlock: commonly used on Kali Linux (mainly username OSINT, but useful in investigations)

  • OSINT Framework: (osintframework.com) – contains image-specific tools and workflows

Browser Extensions (Use Carefully)

Browser extensions are convenient, but come with privacy risks.

  • Exif Viewer (Chrome/Firefox)

  • RevEye – reverse image search

  • Search by Image – multiple engines

  • Fake Image Detector – basic authenticity checks

Mobile Apps for Image OSINT

  • Photo Investigator – EXIF viewer

  • EXIF Metadata Viewer

  • Reverse Image Search apps

  • CamScanner – useful for document images

A Reality Check on Tools & Privacy

Nothing in this universe is truly free.

Free tools often trade privacy and data for functionality.
Paid tools can also collect data.

Always:

  • read permissions

  • avoid uploading sensitive images

  • use tools cautiously

Final Reminder

Image OSINT is powerful, but it must be used responsibly.

Always:

  • verify findings using multiple sources

  • consider context

  • respect privacy and legality

In the next post, we’ll move towards Video OSINT and GEOINT.

Obfuscation and Deobfuscation

I was on Hack The Box Academy, happily reading along when the first word of the module popped up: understanding . Good. Next word: code . Still good. Then the third word appeared: deobfuscation . And I just stared at it like, “How many alphabets did they use to make this word?” I tried pronouncing it five or six times. For a moment, I genuinely believed Shashi Tharoor writes simpler words 😂. Eventually, yes, I managed to say it without hurting my tongue. Anyway, let’s move to the topic. Obfuscation  As the name suggest , it is process of converting simple things ( notes , words , sentences ) into complex form 😂.  More precisely , it is the process of taking a simple , clear sentence and writing it in a complex cipher, using synonyms from a dead language, and adding alot of irrelevant words. The meaning remains preserved, but it is extremely hard to understand ( same as the name of topic obfuscation) .  Defuscation It is simply opposite of obfuscation. It is the proc...

Disclaimer: All the tools and methods discussed in this blog are part of what I am learning in a safe and legal environment . This content is strictly for educational purposes only and is not intended to harm any individual or organization. Even though we all know that theoretical knowledge alone is not enough, most of my learning so far has been on the theory side. From now on, I’ll try to balance both theory and practical understanding — slowly and responsibly. That brings us to today’s topic: OSINT . What is OSINT? OSINT stands for Open Source Intelligence . As the name suggests, it is about gathering information from publicly available sources such as: the internet social media news articles public records OSINT has nothing to do with hacking . It focuses on collecting and analyzing information that is already exposed — often unintentionally. Why OSINT matters in cybersecurity OSINT helps us understand the human attack surface , which is often the weakest link in sec...

Cybersecurity Devices and Technologies Part 1

There is no single device or technology that can solve all the security needs of an organization on its own. A secure network is built by choosing the right tools for the right purpose. This blog covers some of the basic devices and technologies used in the field of network security. Security Appliances Security appliances can be physical devices like routers, or software tools running on those devices. They generally fall into six categories: Routers : Routers primarily connect different network segments, but they also offer basic traffic-filtering features. This helps decide which devices can connect and which networks they’re allowed to communicate with. Firewalls : Firewalls are the guardians of a network. They inspect traffic more deeply and can detect suspicious or harmful behaviour. Firewalls enforce security policies on every packet that passes through them. Intrusion Prevention System (IPS) : An IPS uses traffic signatures to detect and block malicious activities i...
