Auto-marketplace CarGurus disclosed a breach affecting more than 12 million users in February 2026. The exposed dataset includes names, email addresses, vehicle-search history, and some financing-related metadata. Vehicle-search history is more useful for doxxing than it sounds — combined with home address and timing, it can correlate with delivery patterns and routine.

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.
