A German nuclear power plant in Bavaria has admitted that its systems are riddled with malware, and has been shut down as a precaution – a day after the 30th anniversary of the Chernobyl nuclear disaster on Tuesday.
It was reported that the Gundremmingen nuclear power plant is located (75 miles) northwest of Munich, is run by the German utility RWE.
The company admitted that malware had infected a number of its systems. It said it had immediately informed Germany’s Federal Office for Information Security (BSI).
Malware was also reportedly found on 18 removable data drives, mainly USB sticks, in office computers maintained separately from the plant’s operating systems.
The operator said that it has boosted its cyber-security measures, but insisted the malware was not a threat to the facility’s operations because it is “isolated from the Internet.”
This is not the first time that a nuclear power plant has had a security scare. Indeed, the potential risk to systems controlling critical infrastructure and industrial systems remains a worry for many governments and authorities around the world.
In 2015 a hacker managed to hack into the systems of a nuclear power plant in South Korea. A computer worm was later discovered in a device connected to the control system, but the plant operator insisted that the breach had not reached the reactor controls itself.
The hacker later posted files from the hack online, and included a demand for money.
The Stuxnet virus reportedly caused damage to nearly 3,000 centrifuges in the Natanz facility in Iran.
A German steelworks also suffered “massive damage” after a cyber attack on its computer network in late 2014.
