The Polish state-run LOT Airlines has restored regular service after a cyber attack forced it to ground flights for several hours on Sunday afternoon.
The Warsaw-based LOT canceled at least 20 flights, including to Munich, Hamburg and Brussels, after a hacking breach into its on-the-ground information system, spokesman Adrian Kubicki said by phone on Monday. During the disruption, the company was unable to plan flights and planes couldn’t take off.
The systems on the planes were safe and those with planned routes were able to return to the Polish capital, according to LOT’s website.
“We are secure,” Kubicki said. “We know the mechanism and if it was to happen again we’re ready to react quickly.”
LOT informed the police about the attack and is awaiting results of the investigation. Maciej Karczynski, a spokesman for the Internal Security Agency, didn’t have an immediate comment when reached by phone by Bloomberg News. LOT will hold a news conference on its strategy at 1 p.m. in Warsaw on Monday.
