Cyberattack threatened agency's 'command and control'
On Nov. 1, 2011, investigators began looking into an unwanted visitor to U.S. EPA's interconnected system of computers, servers and other devices at its Washington headquarters. The trespasser had gained access with a personal computer to the network at least six times. "The impact of this incident represents a compromise of the command and control of EPA systems and the EPA network," the agency's inspector general said. Such incidents and their dead-end investigations are prevalent in many of the 14 IG reports on EPA cybersecurity incidents obtained by Greenwire. Records touch on hackers' attempts to access EPA computers, leading to potential shenanigans with property and personnel, including the exposure of employees' personal information.
