We’ll email you only about ADT’s future breach filings and how to watch a whole vendor list — not general marketing. Unsubscribe any time.

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.
