Around 1,400 passengers of the Polish airline LOT were grounded at Warsaw’s Frederic Chopin Airport Sunday after a cyber attack temporarily disabled the computer systems that the carrier uses to issue flight plans.
In a press release, the company emphasized that the attack only affected LOT’s ground-based computer systems, not those on its planes, saying that planes that were already in the air would fly to Warsaw as usual.
The hack affected 10 flights that had been bound for destinations including Munich, Brussels, Krakow and Copenhagen.
Although LOT reported that its systems were working again Sunday evening, the attack could have broader implications for airline cyber security.
“We’re using state-of-the-art computer systems, so this could potentially be a threat to others in the industry,” LOT spokesman Adrian Kubicki told Reuters.
The attack is being investigated by authorities, and Kubicki said a commission will investigate the attack, The Associated Press reported.
