　　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. 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 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.
　　The agency said the government contractor violated CBP policies by copying the pictures to the company's computer network. Officials said only the contracting company's network was hit in the cyberattack. The CBP's computer systems remained safe. Civil liberties groups have expressed concern at the general lack of rules covering license plate-reading cameras and image collection by government agencies and law enforcement. Critics say the technology carries the risk of abuses when the private information of citizens is widely shared among agencies or stolen in cyberattacks.
