The attack hit airports in Germany, France, Spain, and several other countries, officials confirmed.
While no flight safety systems were compromised, the disruption caused long lines and confusion at departure halls.
Investigators across Europe are working together to trace its origin. Officials said it was too early to determine whether the attack was state-sponsored or carried out by criminal groups.
Meanwhile, airlines scrambled to revert to manual procedures, with staff checking passports and boarding passes by hand.
Cybersecurity experts noted that airports are increasingly attractive targets for hackers because of their reliance on interconnected IT systems. The attack, they said, highlights vulnerabilities in Europe's critical infrastructure.
Authorities have urged passengers to allow extra time for check-in and said contingency measures remain in place until systems are fully restored.
