Civil Aviation Resources Network, March 28, 2025: According to foreign media reports, Malaysia Airports Holdings Berhad (MAHB) and the National Cyber Security Agency of Malaysia (Nacsa) recently issued a joint statement stating that the operation of Kuala Lumpur International Airport has not been affected by the recent cybersecurity incident. However, several anonymous sources questioned this, saying that preliminary investigations showed that the incident had caused serious interference to the airport's key systems.
According to the New Straits Times, citing industry sources, the cyber attack occurred in the early morning, paralyzing the flight information display system, check-in counters and baggage handling systems, forcing airlines and airport staff to switch to manual operations, directly affecting flight scheduling and passenger travel.
"After the attack, the airport's flight information display screen was intermittently paralyzed for two consecutive days, affecting passengers' access to flight information." An aviation industry insider said, "Thousands of passengers witnessed the display screen not functioning properly, and it cannot be said that operations were not affected."
In addition, sources revealed that due to the lack of a strong backup system, the recovery work was slow, resulting in serious confusion in the flight schedule and causing flight delays on many occasions that day.
Malaysia Airports Holdings Berhad confirmed on the 25th that on March 23, Prime Minister Datuk Seri Anwar Ibrahim disclosed that some computer systems at Kuala Lumpur International Airport had detected cybersecurity threats. MAHB said in a joint statement with Nacsa that after the incident, relevant departments immediately launched an investigation and notified the Malaysian Civil Aviation Authority.
At present, the official has not yet confirmed the specific nature and responsible party of the cyber attack, and the investigation is still ongoing. MAHB emphasized that it will continue to strengthen airport network security protection to ensure the safety and stability of airport operations.
