CBP facility codes sure seem to have leaked via online flashcards
A Quizlet flashcard set titled “USBP Review” was publicly available from February until March 20, when it was made private after WIRED flagged a phone number that could belong to a user near a Kingsville, Texas CBP facility. The set disclosed specific four‑digit codes for various facility entrances, potentially revealing sensitive CBP security procedures. Although WIRED could not confirm the creator was an active CBP agent or contractor, the incident is under review by CBP’s Office of Professional Responsibility; the DHS and ICE have not commented. If the set was produced by a CBP affiliate, it would constitute a serious breach of an agency tasked with safeguarding U.S. borders.
