The Cyberattack on Ukraine's Powergrid
When more than 100,000 people in and around the Ukrainian city of Ivano-Frankivsk were left without power for six hours, the Ukrainian energy ministry accused Russia of launching a cyberattack on the country's national energy grid.
Now reports released by security researchers from the SANS Industrial Control Systems team and the Industrial Control Systems Cyber Emergency Response Team confirm their belief that a cyberattack was responsible for the power cut, making the incident one of the first significant, publicly reported cyberattacks on civil infrastructure.
This is a rare event, of which the most famous example is the Stuxnet malware used to destroy equipment in the Iranian nuclear programme. Many consider Stuxnet so sophisticated that national governments must have been involved. But as is frequently the case, attributing responsibility for Stuxnet has proved difficult, and it's likely that, despite circumstantial evidence, it will be the same in this case.
