CBP facility codes sure seem to have leaked via online flashcards
A public flashcard set exposed confidential gate codes and operational details for a Texas border facility.
A significant potential security breach occurred when a user on the Quizlet platform created a public flashcard set in February containing what appears to be highly sensitive operational information for US Customs and Border Protection (CBP) facilities in Kingsville, Texas. The set, titled 'USBP Review,' was publicly accessible until March 20 and included specific four-digit codes for facility entrances and gates, detailed the agency's internal grid and zone system covering a 1,932-square-mile area, and named 11 CBP surveillance towers in the region. It also described an internal system called 'E3 BEST,' used by officers to query subjects through multiple law enforcement databases.
CBP's Office of Professional Responsibility has launched a review of the incident, which represents a serious lapse for an agency tasked with homeland security. While the Quizlet user's identity and connection to CBP remain unverified, the flashcard set was made private less than half an hour after WIRED contacted a phone number potentially linked to the creator. The exposure comes amid a major hiring surge at CBP and ICE, with agencies offering up to $60,000 in recruitment incentives, raising questions about security protocols during rapid expansion.
