Warsaw's airport experienced hacker attack

Poland's Warsaw airport came under a hacker attack that grounded 1,400 passengers on Sunday afternoon. The attack crashed LOT airline’s passenger registering system and led to the cancellation of 10 domestic and international flights. Adrian Kubicki, a spokesperson for the national carrier, said that the airline was unable to create flight plans and planes couldn't depart from the airport. Passengers that were aboard when the attack occurred continued their journey as their safety was not compromised. “This is the first attack of its kind,” Kubicki told broadcaster TVN24. The problem was resolved after 5 hours, at around 9 pm. Poland's security agencies are investigating the incident.
