A breakdown of Denmark’s train network last weekend was the result of a hacker attack on an IT subcontractor’s software testing environment, Danish train operator DSB said.
“We were contacted by our subcontractor who told us that their testing environment had been compromised by criminal hackers,” DSB’s chief of security, Carsten Dam Sonderbo-Jacobsen, told public broadcaster DR.
“It hasn’t targeted infrastructure or DSB, it was economic crime,” Sonderbo-Jacobsen said in a Reuters report, adding it was not clear who was behind the attack, but that investigations were ongoing.

One of the world’s biggest wind turbine makers, Aarhus, Denmark-based Vestas Wind Systems A/S, shut down computer systems across several locations Saturday to deal with a cyber security incident.
Vestas discovered a cyber security incident Friday and has since then, together with external partners, worked to contain the situation and re-establish the integrity of its IT systems.
The company’s preliminary findings indicate the incident had an impact on parts of Vestas’ internal IT infrastructure and data has suffered compromise.
