As summer travel heats up, a terrifying story is coming out of Poland—flights had to be canceled Sunday because hackers attacked ground computer systems for the state run airline LOT, Reuters is reporting.
“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 said.
Ten flights were canceled and another dozen were delayed by the hacking incident.
Ground computers are used to issue flight plans. The airline has not indicated that passenger information was compromised.
LOT emphasized that planes already in the air when the hack occurred were able to land and safety was never compromised.
The airport in Warsaw is the only location impacted.
No other airlines at the airport were affected.
This hack follows last month’s incident in which cyber security researcher Chris Roberts claimed to have hacked into a United Airlines jet during a flight, briefly taking control of the airliner. Boeing, maker of the plane, said it was impossible. Roberts claimed he accessed the jet controls through the entertainment system, which Boeing said is isolated from other systems. In the wake of Roberts’ claim, United offered 1,000,000 airline miles to anyone who revealed a security threat to the airline.
