The hackers behind a cyberattack that targeted Poland's grid infrastructure met little resistance when they hit systems at a heat-and-power plant and wind and solar farms last month. The Polish report reveals that a private company in the manufacturing sector was also targeted at the same time as these others. But because the attackers in this case didn't manage to take down systems that generate power, their attack on the OT systems had little impact. According to the new report, these were Windows 10 systems used for monitoring and controlling grid systems at the heat-and-power plant.
