AT MIDNIGHT, A week before last Christmas, hackers struck an electric transmission station north of the city of Kiev, blacking out a portion of the Ukrainian capital equivalent to a fifth of its total power capacity. The outage lasted about an hour—hardly a catastrophe. But now cybersecurity researchers have found disturbing evidence that the blackout may have only been a dry run. The hackers appear to have been testing the most evolved specimen of grid-sabotaging malware ever observed in the wild.
Cybersecurity firms ESET and Dragos Inc. plan today to release detailed analyses of a piece of malware used to attack the Ukrainian electric utility Ukrenergo seven months ago, what they say represents a dangerous advancement in critical infrastructure hacking.
