A public Quizlet flashcard set created in February appears to have revealed sensitive security codes for U.S. Customs and Border Protection facilities near Kingsville, Texas. The set, titled 'USBP Review,' was made private on March 20 shortly after WIRED contacted a potentially linked phone number. CBP has launched a review into the matter.
The flashcards detailed four-digit codes for checkpoint doors and specific gates at CBP facilities in the Kingsville area, according to details uncovered by WIRED. Other cards outlined procedures for immigration offenses such as misuse of passports or visas, expedited removals, and warrants, including references to forms and an 'agents Resources Page' checklist. The set also described the local workforce's 1,932-square-mile responsibility covering six counties, an internal grid and zone system— noting one grid does not exist due to highway structures— and listed 11 CBP towers with shared responsibilities.
