Hackers knock out two German energy suppliers

Both affected companies, Entega and Mainzer Stadtwerke have the same IT solutions provider.

Darmstadt-based Entega and Meinz-based Mainzer Stadtwerke were attacked over the weekend. Both companies' websites were still down at the time of publishing this article.

According to a tweet by Entega, the company was hit by an attack that mainly affected the firm's website and staff email accounts. Entega claims that critical infrastructure was not affected, and no customer data was leaked.

Local media reported that Mainzer Stadtwerke also said that critical infrastructure suffered no damage, and no supply failures are expected. Both of the energy providers use the same IT solutions provider, Count+Care. The company's website was also inaccessible at the time of publishing.

Several German wind farms were hit by cyberattacks in recent months. An attack forced Deutsche Windtechnik, a German wind turbine maintenance and repair company, to turn off its IT systems.

Another German wind turbine operator, Nordex, was hit by a cyberattack on the last day of March. As a result, the company was forced to shut down 'various IT systems.' Nordex likely suffered from a ransomware attack.

British, American, European, and other allies claim that the Kremlin was behind cyberattacks against wind farms in Europe.
