A Polish airline grounded planes this weekend after discovering a hack on its systems. The company suggested that the methods used could be applied to any airline.
The BBC reported that Polish airline LOT suffered a hack on the hardware that issues flight plans at Chopin Airport in Warsaw. The airline grounded several flights, affecting the travel plans of thousands of people.
It is not known who perpetrated the attack, or why, and LOT said in a statement released to the BBC that the problem could affect the rest of the industry.
"We're using state-of-the-art computer systems, so this could potentially be a threat to others in the industry," said LOT spokesman Adrian Kubicki.
Airline companies and planes are among the most recent victims of hacking incidents.
The US Government Accountability Office issued a warning in May after the FBI interviewed a passenger who had apparently been able to alter the course of a plane during a flight.

British Airways, meanwhile, admitted to unusual activity on its frequent flier accounts. This was put down to the re-use of passwords, suggesting that it was not a problem with the airline's systems, but with industry standards.
European airline Ryanair was stung in a hacking attack that saw €4.6m transferred to a bank account in China. The firm expected to get the money back, and added that it was shoring up its systems.
"Ryanair confirms that it has investigated a fraudulent electronic transfer via a Chinese bank last week," the company said.
"The airline has been working with its banks and the relevant authorities and understands that the funds, less than $5m, have now been frozen.
"The airline expects these funds to be repaid shortly, and has taken steps to ensure that this type of transfer cannot recur. As this matter is subject to legal proceedings, no further comment will be made."
