(CNET) – The U.S. Customs and Border Protection says photos of travelers into and out of the country were stolen in a "malicious cyberattack" that hit one of its subcontractors in May. None of the images have been identified on the internet or on the dark web, CBP said in a statement Monday.
"In violation of CBP policies and without CBP's authorization or knowledge, [a subcontractor] transferred copies of license plate images and traveler images collected by CBP to the subcontractor's company network," the CBP said. "The subcontractor's network was subsequently compromised by a malicious cyberattack."
The CBP said it's removed from service all of the subcontractor's equipment and is monitoring its work. None of CBP's systems were compromised in the attack.
