Trains Stop for Danish Train Operator DSB

November 4, 2022


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.
