The Indian government has confirmed that seven major airports across the country, including Delhi, Mumbai, Kolkata, Hyderabad, and Bengaluru, were recently targeted in a cyber attack involving GPS spoofing, a sophisticated technique that manipulates navigational signals used by aircraft.
The Directorate General of Civil Aviation (DGCA) has confirmed that it is investigating the incidents. A high-level meeting was held recently between S.K. Sinha, Secretary, Ministry of Civil Aviation, and Faiz Kidwai, DGCA Director-General, to assess the situation. Union Civil Aviation Minister Ram Mohan Naidu Kinjarapu also informed Parliament that flights approaching these airports reported false GPS signals while using GPS-based landing procedures, notably at Runway 10 of Delhiโs Indira Gandhi International Airport (IGI). The incident prompted immediate cybersecurity vigilance across key aviation hubs.
Despite the serious nature of the attacks, aviation experts note that GPS spoofing does not inherently compromise aircraft safety. Modern aircraft are equipped with redundant systems, including Inertial Reference Systems, which can safely navigate even if primary GPS-based systems fail, for durations of up to five hours.
How the Attack Worked
The cyber intrusion reportedly involved GPS spoofing, where aircraft navigation systems receive manipulated GPS signals, creating the illusion that the aircraft is in a different position or altitude than its actual location. While technically serious, the Ministry clarified that no flight operations were disrupted or cancelled, thanks to robust contingency measures and the effectiveness of air traffic control protocols.
High Alert Across Critical Infrastructure
The revelation underscores the vulnerabilities in Indiaโs aviation sector and broader transport infrastructure. Airports affected are among the busiest domestic and international gateways in the country. Authorities have reinforced cybersecurity protocols to ensure continuous monitoring and protection against potential future attacks.
This development follows a previous technical disruption at IGI Delhi in November, which caused widespread delays. While initial reports had raised suspicions of a cyber attack, the issue was later attributed to a technical glitch in the Automatic Message Switching System (AMSS).
Implications for Aviation Security
While no aircraft were directly endangered and operations continued, the week-long incidents over Delhi highlight Indiaโs growing vulnerability to sophisticated cyberattacks on critical infrastructure. ATC officials confirmed that manual interventions were sometimes required, with controllers providing direct navigational guidance to cockpit crews to ensure safe flight operations.
Adding to the strain on aviation operations, the country experienced a temporary disruption in domestic flight schedules earlier this week due to software updates required for Airbus A320 aircraft, affecting around 388 flights. By Sunday, Indian airlines completed the software upgrades, restoring normal operations.
A Wake-Up Call for Aviation Security
Experts note that while the attacks did not result in flight disruptions, they represent a growing cybersecurity challenge for Indiaโs aviation sector, which increasingly relies on GPS-based navigation and automated systems. The government and related security agencies are continuing to enhance monitoring, threat detection, and response mechanisms to safeguard critical transport infrastructure.
As the aviation industry becomes more technologically dependent, incidents like these highlight the urgent need for comprehensive cyber resilience strategies and stronger coordination between airlines, airport authorities, and national cybersecurity agencies.
