Hackers can easily break into Dutch solar panels, which could put the European power supply at risk, according to cyber security investigator Willem Westerhof of ITsec in the Volkskrant.
According to Westerhof, the SMA transformers in many Dutch solar panels are poorly protected and have a "wide range of vulnerabilities". Users aren't prompted to change the default password. The transformers are vulnerable to force attacks. And the devices are secured by one super password of the supplier. If a hacker gets hold of that password, many problems can be caused.
