Hackers were able to get in and mess up Polish airline LOT’s outgoing flight scheduling Sunday.
The attack occurred at Warsaw’s Frederic Chopin Airport, at 4 p.m. and lasted for five hours, during which time ten national and international flights ended up canceled, affecting around 1,400 passengers.
“This afternoon LOT encountered an IT attack that affected our ground operation systems. As a result we’re not able to create flight plans and outbound flights from Warsaw are not able to depart,” said a statement from LOT.
The airline went on to say, “We’d like to underline, that it [the attack] has no influence on plane systems. Aircraft that are already airborne will continue their flights. Planes with flight plans already filed will return to Warsaw normally.”
LOT got the issue under control, and all affected passengers ended up reaching their destinations through other flights or booked into a hotel if they needed to stay the night.
Polish officials immediately started and investigation into the incident. There is currently no information on who carried out the attack, and no online hacker group has claimed it yet.
