#CyberSecurity#Russia#Sandworm#PowerGrids#Ukraine#StateHacking: "Cybersecurity firm Mandiant today revealed that Sandworm, a cybersecurity industry name for Unit 74455 of Russia's GRU spy agency, carried out a third successful power grid attack targeting a Ukrainian electric utility in October of last year, causing a blackout for an unknown number of Ukrainian civilians. In this case, unlike any previous hacker-induced blackouts, Mandiant says the cyberattack coincided with the start of a series of missile strikes targeting Ukrainian critical infrastructure across the country, which included victims in the same city as the utility where Sandworm triggered its power outage. Two days after the blackout, the hackers also used a piece of data-destroying "wiper" malware to erase the contents of computers across the utility's network, perhaps in an attempt to destroy evidence that could be used to analyze their intrusion."
