Named in this incident?

You can’t unleak data. You can take away what it’s worth.

A leaked record is where it starts, not where it ends. What turns it into your front door is the look-up sites publishing your address beside your name — and those are what an AI reads when somebody asks about you. The free scan shows you both. We write to 580 companies.

Home-security customers — including streamers, gamers, and creators with public personas — are now associated with confirmed home addresses in a leaked dataset. Address data plus alarm-status metadata is exactly the kind of context that fuels stalking and physical-intimidation threats. Public reporting suggests this category of data is increasingly cross-referenced with public-records aggregators in targeted operations.
