Search yourself the way a stranger would, to see what they'd see.
OSINT (open-source intelligence) is the art of reconstructing a person from what's lying around online: a handle, a photo, an email address, an old ad. This theme teaches you those techniques by turning them on yourself. You investigate yourself to measure, concretely, what a stranger can piece together in a few searches.
You move by pivots: from a handle to the accounts sharing it, from an email to the breaches exposing it, from a photo to the place it gives away. Then you correlate, conclude and close the doors. One rule frames the whole theme: these methods are for auditing yourself. Using them on a third party without a legal basis is forbidden, and the final level states it plainly.
Learn the four starting points of any investigation on a person.
List your pivots (name, handle, email, number): that's the starting map of your self-investigation.
10 exercises per level, mixing decision, spotting and quiz. The first 2 levels are free; the next ones open with the Pro or Elite subscription.
Each level ends with a mission: what remains to be done once the lesson is understood. Some rely on your report, others on a setting we cannot see: it says so each time.
Write down your pivots: full name, handles, email addresses, phone number. Search each one in quotes on two different search engines, in a private window, and keep a list of what comes up. That's your starting point.
One email address or one handle is enough to unroll the map of your accounts. Your scan walks that path in an investigator's place: see which accounts are tied to it. For the ones you want kept apart, switch to another address or handle.
Enter the address of an old blog or an old profile into a public web archive. What you deleted may live on there. If an archived page exposes you, look up the archive's removal procedure.
Go back over your last five public photos and look at the background like an investigator: house number, number plate, shop sign, the view from the window. Delete or crop the ones that place your home.
Go back to your scan and rank what it shows by severity: whatever leads to your door, address and phone number, comes before the rest. Deal with the first item today; the cosmetic stuff can wait.
