The cyberattack took advantage of a known weakness in Cisco firewalls to trigger a series of five-minute communications outages over a span of about 12 hours, according to an emergency report sPower filed with the Department of Energy at the time of the disruption that was not publicly released. Denial-of-service attacks flood target devices or websites with bogus traffic to crash them. The cybersecurity incident is the first confirmed to have caused 'interruptions of electrical system operations,' based on DOE records. Experts say the hackers behind the attack may not have known they were affecting the power grid, based on the fact that Cisco firewalls are used in a range of industries and are a popular target of opportunity when left exposed to the internet. In September, the North American Electric Reliability Corp. posted a document revealing that the attack created blind spots at a grid control center, but it was not known until now which specific company was affected."
