The New York Times reports after years of cyberattacks on the networks of high-profile government targets like the Pentagon, Chinese hackers appear to have turned their attention to far more obscure federal agencies. Law enforcement and cybersecurity analysts in March detected intrusions on the computer networks of the Government Printing Office and the Government Accountability Office, senior American officials said this week. The printing office catalogs and publishes information for the White House, Congress and many federal departments and agencies. It also prints passports for the State Department. The accountability office, known as the congressional watchdog, investigates federal spending and the effectiveness of government programs.
