Millions of solar power systems worldwide have critical security vulnerabilities which could be used by hackers

• Insecure solar systems allow cybercriminals to steal data and ransom access
• Millions of solar inverters remain vulnerable to severe cybersecurity threats
• Forescout – Vedere uncover flaws allowing attackers to take full control over solar systems

The increasing use of solar power has exposed critical cybersecurity vulnerabilities in inverters, cloud computing services, and monitoring platforms, creating an insecure ecosystem where hackers can manipulate energy production, disrupt power grids, and steal sensitive data, posing serious risks to global energy infrastructure, experts have warned.

A study by Forescout – Vedere Labs identified 46 new vulnerabilities across three major solar inverter manufacturers, including Sungrow, Growatt, and SMA. Previous findings showed that 80% of reported vulnerabilities were high or critical in severity, with some reaching the highest CVSS scores.
