Tools, tactics, and fresh investigations expanding the open-source intelligence toolkit.
Some of the best OSINT pivots start with the things people forget about. A phone number that has quietly followed someone across a decade of accounts. A methodology buried in a blog post that could be running in the background of every future investigation.
This episode covers Issues 107 and 108 of The OSINT Newsletter and explores two sides of how modern investigators get more out of what they already have: squeezing real intelligence out of the most overlooked data point in the toolkit, and turning the methodology in your head (and other people’s heads) into something an AI agent can run on your behalf.
In Episode 19 of The OSINT Podcast, host Jake Creps starts with Issue 107 and one of the most underrated data points in the toolkit: the phone number. He walks through what intelligence actually comes from a number, where to check first without overcomplicating it, and a clean five-step workflow from standardising the format through to pivoting outward into the wider account network. He covers the platforms worth checking (WhatsApp, Telegram, Signal, Truecaller, Sync.ME), the carrier and HLR lookups that ground a number geographically, and the high-value pivots, usernames, social accounts, and breach data, that turn a single number into a network. He closes with how to handle disposable numbers and burner tactics, where the absence of data is itself a signal.
Highlights include:
📞 What a Phone Number Actually Tells You – geographic origin, platform presence, and identity fragments hiding in plain sight.
🧠The Five-Step Workflow – from standardising the format to pivoting outward, a clean methodology for running phone number OSINT without skipping steps.
🔥 Burner Logic – why disposable numbers are not a dead end, and how patterns of behaviour and gaps in data become signals in their own right.
🤖 Codifying Methodology – discovering methods worth codifying with a Google Dork, turning them into local markdown, and chaining skills together into a continuous discovery engine.
🔗 A Worked Investigation – running /username through Sherlock, pivoting into /person-search on nxthacker99, and producing a full subject profile assessment with named intelligence gaps.
Whether the investigation starts with a single phone number or a methodology lifted from someone else’s blog post, Episode 19 is about getting more out of the OSINT you already have in front of you.
