Russian hackers infiltrated US electric utilities last year and had the ability to cause widespread blackouts, the Department of Homeland Security (DHS) said in a briefing on Monday.

美国国土安全部(DHS)上周一在一份简报中表示，俄罗斯黑客曾于2017年侵入美国电力公司的系统并有能力造成大规模停电。

Symantec first reported on a hacking campaign by the state-sponsored group Dragonfly targeting dozens of victims in the US energy sector in 2017.

赛门铁克Symantec首次向外通报了由国家支持的蜻蜓Dragonfly组织在2017年针对美国能源部门的数十起黑客攻击活动。

美国国土安全部第一次在没有保密等级的公开文件中披露攻击事件的细节，并表示黑客攻击了数百名受害者”。

Attacks began in 2016 and continued through 2017, and DHS officials said it's likely the campaign is still ongoing.

非法侵入始于2016年，并持续到2017年，国土安全部官员表示，可能今天仍在继续。

By first penetrating the networks of power companies' trusted vendors, hackers for Dragonfly, also known as Energetic Bear, were able to access utility networks, The Wall Street Journal reported Monday, citing officials at the DHS.

华尔街日报　援引了国土安全部官员的观点，认为蜻蜓组织(也称为Energetic Bear)的黑客先渗透了电力公司所信赖的供应商的网络系统，进而获得了能够访问公共事业网络的权限。

Russians used email phishing scams and fake websites to gain access to corporate networks.

"They got to the point where they could have thrown switches" and caused power outages, said Jonathan Homer, chief of industrial-control-system analysis for DHS.

Experts told The Journal it was unclear whether the attack was done in isolation or in preparation for a larger operation.

The DHS confirmation comes amid increasingly tense relations between Moscow and Washington.
