What Leaked About You

useosint

Checks an email, username, phone, or name against curated data-breach services - Have I Been Pwned, DeHashed, IntelX and the like - to enumerate which breaches an identity appears in and read what those records reveal, chiefly the list of services the person actually used. It is breach-exposure reconnaissance about a person, not a codebase tool: it does not scan your repository for hardcoded secrets, and it never uses a leaked password to access anything - reading the exposure is the whole job.

A situation it fits

While cleaning out a dusty server closet, you spot a sticky note with your 2014 gaming alias. You dive into dump trawlers to see which tiny subscription box sites and forgotten hobby forums once held that string, purely to build a hit list, never to touch a password field.
What Leaked About You. This skill performs targeted reconnaissance on a single individual’s historical data exposure, querying compiled leak indexes to discover which external services originally stored a given identifier, without attempting to exploit or access anything. It wins here because your scenario explicitly describes trawling dumps to catalogue which small third-party businesses once held your old tag, which maps exactly to that exposure-readout mission, whereas the other options focus on writing code scanners, patching dependencies, or sanitizing server error output.
