Hackers could target electricity grids through security flaws in solar panel equipment, a Dutch researcher has said.<\/p>\n
Willem Westerhof found 17 vulnerabilities in inverters, which convert electricity produced by the panels so it can be used on the grid.<\/p>\n
He said internet-connected inverters could be targeted by hackers.<\/p>\n
One manufacturer said that only “a small fraction” of its devices were affected.<\/p>\n
After discovering vulnerabilities in devices produced by a range of manufacturers, Mr Westerhof carried out a field test near Amsterdam on two inverters made by SMA.<\/p>\n
He told the BBC the test showed it would be possible for an attacker to remotely control the devices and alter the flow of power.<\/p>\n
Because energy equipment on the grid needs to balance supply with demand, overloading the system could result in a power cut.<\/p>\n
‘Serious consequences’<\/strong> Energy researcher Iain Staffell, at Imperial College London, told the BBC, “It’s certainly a risk to electricity supply and could stress grid operations.”<\/p>\n However, he did not believe it could cause blackouts and he pointed out that a large number of inverters would have to be attacked at once for any significant effect to occur.<\/p>\n “The security of our devices has highest priority for SMA in all respects,” the company said in a statement.<\/p>\n “We already assessed the mentioned issues on a technical basis and [are working] intensively on the correction.”<\/p>\n It added that it would publish further responses to Mr Westerhof’s research in the coming days and that it was working on a report about the security of its products with the Dutch National Cyber Security Centre.<\/p>\n Asking users to change passwords was a way of pushing liability away from the manufacturer, said cyber-security researcher Tom van de Wiele, at F-Secure.<\/p>\n “The vulnerabilities are real,” he said, though he agreed with SMA that not all inverters would be open to attack. He added that he had seen similar security issues in other industrial products.<\/p>\n Mr Westerhof discovered the security flaws while working on his undergraduate thesis and detailed the research in a talk at the SHA2017 security conference in the Netherlands on Monday.<\/p>\n He said he had decided not to release full details of potential attacks on the inverters, to avoid encouraging malicious hackers.<\/p>\n “Solar producers should seek to isolate the products from the internet ASAP,” said Dave Palmer, director of technology at cyber-security company Darktrace.<\/p>\n “And [they should] also review their physical access security to reduce the risk of a local attack from someone physically breaking into their facilities.”<\/p>\n –<\/p>\n Source: BBC<\/p>\n","protected":false},"excerpt":{"rendered":" Hackers could target electricity grids through security flaws in solar panel equipment, a Dutch researcher has said.

\n“If an attacker does that on a large scale, that has serious consequences for the power grid stability,” said Mr Westerhof.<\/p>\n
\n“Just because you bought one of their products and a solar array, [it does not mean] that you are vulnerable.”<\/p>\n
