Willem Westerhof, a Dutch researcher, has found 17 vulnerabilities in the inverters manufactured for use in solar panels. In a test performed near Amsterdam, he found that the vulnerabilities could allow hackers to enter and the hack into the main power grid connected to the solar panels.
In an interview with the BBC, Mr. Westerhof stated that “If an attacker does that on a large scale, that has serious consequences for the power grid stability.”
The BBC also quoted Dave Palmer, director of technology at cyber-security company Darktrace as stating, “Solar producers should seek to isolate the products from the internet ASAP… And [they should] also review their physical access security to reduce the risk of a local attack from someone physically breaking into their facilities.”
