CBP Facility Codes Sure Seem to Have Leaked Via Online Flashcards

A public Quizlet set called “USBP Review” allegedly exposed CBP gate and checkpoint codes, area maps, and internal procedure notes near Kingsville, Texas.

The material could point to operational security details for U.S. Customs and Border Protection facilities and raise risks for border security.

After WIRED contacted a phone number possibly linked to the set, the flashcards were made private.

CBP said its Office of Professional Responsibility is reviewing the matter.
