Warsaw: A cyber attack against Polish flagship carrier LOT grounded more than 1,400 passengers at Warsaw`s Frederic Chopin Airport on Sunday, a spokesman said.
The attack occurred at around 4:00 pm local time (1500 GMT), and targeted the airline`s ground operations system, it said in a statement.
The incident, which led to the cancellation of 10 flights departing from Warsaw, was resolved by 9:00 pm.
"This is the first attack of its kind," LOT spokesman Adrian Kubicki told TVN 24 television.
The airline said in a statement on its website that the "IT attack" meant it was unable to create flight plans and flights were not able to depart from Warsaw.
Poland`s security agencies were investigating the attack.
