Hoover Dam transformer explodes; no one hurt
BOULDER CITY, Nev. (AP) — A transformer exploded Tuesday at Hoover Dam, one of the nation’s largest hydroelectric facilities, producing a thick cloud of black smoke and flames that were quickly extinguished. No one was hurt in the explosion near the base of the dam, an engineering marvel on the Colorado River that straddles the border of Arizona and Nevada. Electricity produced at Hoover Dam continued flowing to the 8 million people in Arizona, Nevada and Southern California who rely on it, the Western Area Power Administration said. The cause of the fire was under investigation and officials were working to determine the extent of damage to the transformer, one of 15 at the complex that control the voltages for power sent to customers.

Predatory Sparrow: Did hackers start this steel factory fire in Iran?
It's extremely rare for hackers, who operate in the digital world, to cause damage in the physical world. But a cyber-attack on a steel maker in Iran two weeks ago is being seen as one of those significant and troubling moments. A hacking group called Predatory Sparrow said it was behind the attack, which it said caused a serious fire, and released a video to back up its story. The video appears to be CCTV footage of the incident, showing factory workers leaving part of the plant before a machine starts spewing molten steel. It ends with people pouring water on the fire with hoses. Source
