OSINT tip of the day 🔍📱 Ever landed on a Facebook profile that looks completely empty… no posts, no photos, nothing? You think, “well, that's nothing to find,” right? 😅 Wrong. Sometimes the quietest profiles talk the loudest 👀. A lot of people forget that Facebook Marketplace reveals plenty, and all you need is their User ID. Just go to: If they’ve sold anything, listed items, or interacted on Marketplace, you’ll often find clues about their activity, habits, or even location 🧩🛒. It’s one of those hidden corners of Facebook that most people never check, but it can be surprisingly helpful during OSINT investigations. __________ P.S. ♻️ Repost if you found this helpful.

🛑 A powerful OSINT tool for exploring global sanctions data If you ever need to check sanctions across different authorities, this tool brings everything together in one place and it’s FREE to use. It’s called Sanctions Explorer, and it provides: ✅ Current + historical sanctions data 📚 ✅ Coverage from major bodies like the UN, EU, OFAC, and more ✅ Clean filtering to track individuals, companies, and entities ✅ A unified view instead of searching each authority separately 🌍 The project was initiated by Archer (a Berkeley-based nonprofit focused on human rights) and later fully developed by the C4ADS Data & Technology team known for their evidence-based research on global conflict and transnational security. If sanctions research is part of your OSINT workflow, this tool is worth bookmarking. And in the next post, I’ll share a quick OSINT tip for checking phone numbers on Telegram Check it out here: __________ P.S. ♻️ Repost if you found this helpful.

Deleting yourself from the internet is possible, and here’s how: When I began learning OSINT, the first thing I did was search for my online presence 🔍. I was shocked by the amount of information I found. To reduce my digital footprint, I started by deleting unused accounts, photos, and posts. Some websites make it challenging to delete your account or remove personal information ⚠️ One of the best resources I found was JustDeleteMe, a directory of direct links to delete your account from various web services. Here’s how to use JustDeleteMe: 1. Visit JustDeleteMe 2. Type the name of the website from which you want to delete your account 3. Click on “view info” 4. Follow the instructions to remove your account 🗑️ I highly recommend conducting an OSINT investigation on yourself first. This helps you understand how people use the internet and what information might be interesting to an OSINT investigator 👀 Additionally, I recommend using Google Alerts to monitor any search results that might contain your or your client’s information. In a future post, I’ll share how to use Google Alerts to gather information about individuals or companies. ____________________________ P.S. ♻️ Repost if you found this helpful.

Most investigators stop their research when they see a Cloudflare IP That’s a mistake! Cloudflare hides the origin server’s real IP address but it doesn’t always make it impossible to find. With the right techniques, you can often uncover the actual hosting infrastructure behind a protected website. Here are 3 methods I regularly use: 🧠 Criminal IP Search Engine: One of the fastest ways to investigate infrastructure behind a domain. 🔎 Reverse Favicon Search: Some websites reuse the same favicon across multiple services or subdomains. Searching by favicon hash can reveal infrastructure that isn’t behind Cloudflare. 📜 WHOIS History: Older WHOIS records sometimes expose previous hosting providers or IP addresses used before Cloudflare protection was enabled. Using Criminal IP, you can pivot from a domain and uncover: ✅Possible origin server IPs ✅Passive DNS history ✅ Abuse records ✅Malware associations ✅Scanner activity ✅Related infrastructure Example: I searched a Cloudflare-protected domain inside Criminal IP and it immediately revealed the underlying server IP where the website was actually hosted. Most people never go this far but this step often unlocks the biggest findings in a website investigation. Try out the search engine:

Here is how I investigate a Google account without tools 🔍 Not everybody has the resources to set up Linux as a virtual machine. That’s why it’s always a good idea to have a list of websites that can do this for you 🌐 You’ll find a list of OSINT (Open‑Source Intelligence) resources at the link provided at the end of this post. The first thing you need is the person’s email address 📧 There are many ways to find someone’s email, which I’ll cover in future posts. Once you have their email, you can use an online version of a tool called Ghunt 🛠️ Ghunt is used to investigate Google accounts. Normally, you need Python to run it, but you can also use it online without setting it up on your machine. It can reveal the following about a Google account: ● Account profile picture ● Google reviews associated with the account ● Last profile edit ● Account type Use the following URL to visit the website: There are more methods to find information about an email address that I’ll cover in future posts 👀 __________ P.S. ♻️ Repost if you found this helpful.

OSINT tool of the day 🌐🕵️‍♂️ My favourite business-verification tool this week is OpenLEIS, a public database that shows what’s really behind a company 📂. It lets you search for LEI codes (Legal Entity Identifiers) LEI are unique IDs used in global financial transactions to confirm a company actually exists and who stands behind it 🧩. This makes it super useful in OSINT investigations Especially when you want verified business details instead of unreliable guesses 🔍. With OpenLEIS you can quickly check: 🛑 company name and legal address 🛑 active / inactive status 🛑 registration and update dates 🛑 links to parent or subsidiary companies Some practical ways it helps during investigations: 🛑 verifying companies offering investments or financial deals 🛑 analysing businesses that might be using shell structures 🛑 finding connections between companies in corruption or sanctions cases If you enjoy tools that reveal what’s hiding behind a business, you’ll like this one 🚀.
