Hackers had the power to cause blackouts, Symantec says. And yes, most signs point to Russia.
Andy Greenberg writes: In an era of hacker attacks on critical infrastructure, even a run-of-the-mill malware infection on an electric utility’s network is enough to raise alarm bells. But the latest collection of power grid penetrations went far deeper: Security firm Symantec is warning that a series of recent hacker attacks not only compromised energy companies in the US and Europe but also resulted in the intruders gaining hands-on access to power grid operations—enough control that they could have induced blackouts on American soil at will.
Symantec on Wednesday revealed a new campaign of attacks by a group it is calling Dragonfly 2.0, which it says targeted dozens of energy companies in the spring and summer of this year. In more than 20 cases, Symantec says the hackers successfully gained access to the target companies’ networks. And at a handful of US power firms and at least one company in Turkey—none of which Symantec will name—their forensic analysis found that the hackers obtained what they call operational access: control of the interfaces power company engineers use to send actual commands to equipment like circuit breakers, giving them the ability to stop the flow of electricity into US homes and businesses.
“There’s a difference between being a step away from conducting sabotage and actually being in a position to conduct sabotage … being able to flip the switch on power generation,” says Eric Chien, a Symantec security analyst. “We’re now talking about on-the-ground technical evidence this could happen in the US, and there’s nothing left standing in the way except the motivation of some actor out in the world.”
Never before have hackers been shown to have that level of control of American power company systems, Chien notes. The only comparable situations, he says, have been the repeated hacker attacks on the Ukrainian grid that twice caused power outages in the country in late 2015 and 2016, the first known hacker-induced blackouts.
The Usual Suspects
Security firms like FireEye and Dragos have pinned those Ukrainian attacks on a hacker group known as Sandworm, believed to be based in Russia. But Symantec stopped short of blaming the more recent attacks on any country or even trying to explain the hackers’ motives. Chien says the company has found no connections between Sandworm and the intrusions it has tracked. Nor has it directly connected the Dragonfly 2.0 campaign to the string of hacker intrusions at US power companies—including a Kansas nuclear facility—known as Palmetto Fusion, which unnamed officials revealed in July and later tied to Russia.
Chien does note, however, that the timing and public descriptions of the Palmetto Fusion hacking campaigns match up with its Dragonfly findings. “It’s highly unlikely this is just coincidental,” Chien says. But he adds that while the Palmetto Fusion intrusions included a breach of a nuclear power plant, the most serious DragonFly intrusions Symantec tracked penetrated only non-nuclear energy companies, which have less strict separations of their internet-connected IT networks and operational controls.

(Reuters) – Jim Finkle writes: Researchers have discovered a group of highly sophisticated hackers operating for hire out of China, a U.S. computer security company said on Tuesday, and it linked them to some of the best-known espionage attacks in recent years.
Symantec Corp said the group, which it dubbed “Hidden Lynx,” was among the most technically advanced of several dozen believed to be running cyber espionage operations out of China. Unlike a previous report by another company, Symantec did not accuse the Chinese government of involvement in the cyber attacks.
Symantec’s 28-page report described Hidden Lynx as a “professional organization” staffed by between 50 and 100 people with a variety of skills needed to breach networks and steal information, including valuable corporate secrets. Read the rest of this entry »
