Photograph by Philipp Katzenberger U.S. federal agencies, including the Treasury and Commerce departments, were spied on by hackers suspected to work for the Russian government, officials acknowledged Sunday after Reuters first revealed the incident. The hackers had access to internal email traffic and the breach was serious enough to prompt a meeting of the National Security Council at the White House on Saturday, Reuters said. According to U.S. officials quoted by The Wall Street Journal, the breach may be related to the hacking earlier this year of cybersecurity firm FireEye, a company with major business and government contracts.
