U.S. Customs and Border Protection has confirmed to The Washington Post a data breach has exposed photos of travelers and vehicle information of those entering or exiting the country. The information was accessed through a subcontractor in what was called a "malicious cyber attack."

"CBP has alerted Members of Congress and is working closely with other law enforcement agencies and cybersecurity entities, and its own Office of Professional Responsibility, to actively investigate the incident," the agency said in a statement to The Hill.

Another blemish on the record of the software came last September when a report — released by the Department of Homeland Security's Office of the Inspector General — announced the program had numerous challenges that needed to be handled before a wide rollout.
