“Today, only days from the 1-year anniversary of that first confirmed cyber-enabled attack on an electric power system, we are experiencing a bit of deja vu. Recent reports from Ukrainian media have indicated and increasing trend in malicious cyber-activity including distributed denial of service (DDoS) attacks on government websites and payment systems, and new report today of a new possible cyber-attack to the Ukraine electric system. But this time is different – where the previous attacks had impacted only the electric distribution system, this latest attack is reported to have resulted in the de-energizing of a transmission-level substation.
