CBP Facility Codes Sure Seem to Have Leaked Via Online Flashcards

Summary of Article on Confidential CBP Information Exposure on Quizlet

In February, a user on Quizlet—an online learning platform—created a public flashcard set titled “USBP Review” that contained highly confidential information about the security procedures at US Customs and Border Protection (CBP) facilities near Kingsville, Texas. This set remained publicly accessible until March 20, when it was made private shortly after WIRED contacted a phone number linked to the Quizlet user. While the individual listed with the Quizlet user has an address near a CBP facility, WIRED has not confirmed whether the individual created the set while actively working for CBP. CBP’s Office of Professional Responsibility confirmed the incident is under review. The set detailed specific codes for facility access points, federal immigration charges, and an internal CBP investigation system. The exposure of such information could represent a serious breach within an agency tasked with safeguarding national security. Meanwhile, Quizlet assured that it takes reports of sensitive content seriously and encourages users to report any concerning material.
