CBP Facility Codes Sure Seem to Have Leaked Via Online Flashcards

A publicly accessible Quizlet flashcard set titled “USBP Review” apparently exposed highly confidential information — including specific four-digit checkpoint and gate access codes — for a U.S. Customs and Border Protection facility in Kingsville, Texas. The set was removed from public view shortly after WIRED contacted an individual potentially linked to the account; CBP has opened a review but WIRED could not confirm whether the author was an active CBP employee or contractor.
