Airport Director Robert Kennedy said this week that the airport has experienced an unspecified number of unsuccessful system intrusions since the April cyberattack.
Cleveland.com reports it took the airport a week to get its systems back online after malware was discovered. The attack shut down flight and baggage information boards, as well as the airport's internal email system.
Cleveland officials said then that they planned to integrate the airport with the rest of the city's computer systems and bolster general cybersecurity.
Kennedy says some of those improvements include adding staff to the computer security teams and upgrading equipment.
