Cyber-espionage campaign strikes energy sectors in Europe and US

A massive cyber-espionage campaign targeting energy companies in the United States and Europe has successfully broken into the core systems that control the companies’ operations, according to security firm Symantec.

Malicious email campaigns have been used to gain entry into organisations in the United States, Turkey and Switzerland, and likely other countries as well, Symantec said in a report published on Wednesday.

The cyber attacks, which began in late 2015 but increased in frequency in April of this year, are probably the work of a foreign government and bear the hallmarks of a hacking group known as Dragonfly, Eric Chien, a cyber security researcher at Symantec, said in an interview.

The research adds to concerns that industrial firms, including power providers and other utilities, are susceptible to cyber attacks that could be leveraged for destructive purposes in the event of a major geopolitical conflict.

In June, the US government warned industrial firms about a hacking campaign targeting the nuclear and energy sectors, saying in an alert that hackers sent phishing emails to harvest credentials in order to gain access to targeted networks.

Chien said he believed that alert likely referenced the same campaign which Symantec has been tracking.

He said dozens of companies had been targeted and that a handful of them, including some in the US, had been compromised on the operational level. That level of access meant that motivation was “the only step left” preventing “sabotage of the power grid,” Chien said.

However, other researchers cast some doubt on the findings.

While concerning, the attacks were “far from the level of being able to turn off the lights, so there’s no alarmism needed,” said Robert M. Lee, founder of US critical infrastructure security firm Dragos Inc, who read the report.

Lee called the connection to Dragonfly “loose.”

Dragonfly was previously active from around to 2011 to 2014, when it appeared to go dormant after several cyber firms published research exposing its attacks. The group, also known as Energetic Bear or Koala, was widely believed by security experts to be tied to the Russian government.

Symantec did not name Russia in its report but noted that the attackers used code strings that were in Russian. Other code used French, Symantec said, suggesting the attackers may be attempting to make it more difficult to identify them.

In February, Ukraine made repeated accusations that Russian hackers were targeting its power grid, financial system and other infrastructure with a new type of virus that attacks industrial processes.
