Internet hackers have stolen tens of thousands of pictures of travelers and vehicles collected at the United States border. U.S. Customs and Border Protection, or CBP, officials confirmed the attack on Monday. The agency said the photographs were stolen from the computer network of a contractor that captures the images for the government. Officials did not name the contractor. A CBP spokesman told the Associated Press that the agency believes that the incident involved the photographs of fewer than 100,000 people. Images were taken of travelers in vehicles entering and leaving the United States at a single land border crossing over one-and-a-half months, the spokesman said. The images also included license plates of vehicles crossing the border. The CBP said in a statement that it learned of the cyberattack on May 31.
