Welcome to the first mid-month OSINT review. I’ll be publishing these every month in the middle of the month showcasing all of the interesting research and content I’ve looked into so far as part of my research into open source intelligence.

This issue is broken up into an OSINT Reads section that contains longer form content followed by OSINT Twitter which highlights the top research I’ve seen so far this month.

If there’s anything I left out that you think is worth mentioning, please let me know!

Thanks again for reading and if you haven’t already subscribed, here’s an easy way to do it.

I write about using ChatGPT for writing and reading regex for OSINT use cases.

Jake Creps @jakecreps

☕️ Good morning. You can use ChatGPT to write regex for you. Here are some examples for OSINT. Emails: ^[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}$ Phone numbers: ^(\+?\d{1,3}[- ]?)?\(?\d{3}\)?[- ]?\d{3}[- ]?\d{4}$ Bitcoin wallets: ^[13][a-km-zA-HJ-NP-Z1-9]{25,34}$

I also used ChatGPT to write a bookmarklet that extracts all email addresses on your active web page and saves them to a CSV including the source domain they were found on.

Jake Creps @jakecreps

☕️ Good morning. I created a bookmarklet that extracts emails from a page, including the domain of the page extracted from, and saves the results as a CSV named the URL of the page it was extracted from. It's been a useful tool for #OSINT automation:

Ivano Somaini writes about using password recovery methods to disclose partial mobile phone number and credit card information from a PayPal account.

Ivano Somaini @IvanoSomaini

#OSINT🧵Tipp PayPal : How to diclose someone’s 5 digits of mobile and country prefix by email: - click on password forgot - insert target e-mail -...and the mobile phone digits are diclosed... -...in some cases even information about the credit card

On the note of password recovery methodology, remember that this is a grey area and should be used carefully and ethically.

I write about using the Bitmoji API to verify if a Snapchat, or any other Bitmoji-enabled account, is associated with an email address.

Jake Creps @jakecreps

#OSINT Snapchat reverse email / verification 1⃣Request URL: bitmoji.api.snapchat.com/api/user/find 2⃣Request Body: {"email":"<email address>"} ✅ Response Body: If response, email match
