The Rising Tide of Cyber Threats in Aviation

The aviation sector is witnessing an unprecedented rise in cyber-attacks, with the nature of attacks growing more sophisticated and frequent. Bridewell’s 2024 report states that 61% of aviation companies had a ransomware attack on them in the last 12 months, while 26% were victims of such attacks. Moreover, the organizations also saw an average of 21 phishing attacks and six nation-state attacks per respondent.

The cost is enormous. Cyber breaches can result in huge penalties from regulators and litigious action, with the cost estimated at billions per year. Additionally, the aviation sector experienced a 131% rise in cyber-attacks between 2022 and 2023, with the largest percentage being directed at airspace users.

These figures emphasize the paramount necessity of having good cybersecurity measures, especially cybersecurity testing, to protect airline systems against new threats.

Understanding the Cyber Threat Landscape in Aviation

GPS Spoofing and Navigation System Attacks

GPS spoofing has become a major threat, with a 400% increase in incidents targeting commercial airliners in the past few months. The attacks have the capability to deceive aircraft navigation systems and divert aircraft off course. In other instances, spoofing has even caused onboard clocks to be tampered with, causing encrypted communication systems to fail and grounding aircraft for hours.

Ransomware and Malware Attacks

Ransomware attacks are now more common, with 55% of U.S. aviation organizations suffering from such attacks over the last year. The attacks can disrupt airline operations, causing flight cancellations, data breaches, and huge financial losses.

Operational Disruptions from IT Outages

The use of sophisticated IT systems in the aviation sector exposes it to service disruptions. In July 2024, a malfunctioning software update by cybersecurity firm CrowdStrike resulted in a worldwide IT meltdown, impacting Windows computers globally. The episode caused more than 4,295 cancellations and delays of flights, showcasing the domino effect that IT breakdown has on airlines’ operations.

The Imperative of Cybersecurity Testing in Aviation

Cybersecurity testing is an active method of finding and remediating vulnerabilities in airline systems. It involves several methodologies, such as penetration testing, vulnerability assessment, and security audit, to make sure systems are resistant to cyber threats.

Penetration Testing

Penetration testing mimics cyber-attacks to detect vulnerabilities in systems prior to malicious exploitation. Through imitation of actual attack situations, airlines are able to determine their security stance and take appropriate measures.

Vulnerability Assessments

Periodic vulnerability assessments assist in the detection and closure of security loopholes in software and hardware elements. These tests are essential for ensuring compliance with industry standards and regulations.

Security Audits

Comprehensive security audits assess the efficacy of current security policies and measures. They identify areas where improvement is needed and assist in the integration of security strategies with organizational objectives.

Regulatory Landscape and Compliance Requirements

The aviation sector is under close regulatory controls seeking to improve cybersecurity. In 2023, the Federal Aviation Administration (FAA) developed new cybersecurity guidelines requiring airplane companies and operators to put in place strict measures for combating cyber risks. The International Air Transport Association (IATA) is further creating requirements for operators to develop a closer cybersecurity partnership and openness.

Adherence to these regulations requires strict cybersecurity testing to confirm that airline systems are resilient to emerging cyber threats.

Protecting Airline Systems from Emerging Cyber Threats

As aviation systems grow increasingly interconnected and reliant on advanced technologies, the sector faces a dramatic rise in both the volume and sophistication of cyber threats. Cyberattacks on airline systems are no longer theoretical—they are persistent and real, targeting critical infrastructure with the potential to compromise safety, operational continuity, and passenger trust.

Avionics and In-Flight Systems

Modern aircraft are equipped with intricate avionics systems responsible for navigation, communication, and control. These systems, if compromised, can pose life-threatening risks. Threat vectors such as GPS spoofing, unauthorized access to flight data protocols, or interference in in-flight Wi-Fi systems can allow attackers to tamper with flight data or inject malicious code. Penetration testing and hardware security assessments are essential to identify vulnerabilities in aircraft communication channels and ensure systems like ADS-B (Automatic Dependent Surveillance–Broadcast) are not exposed to manipulation.

Air Traffic Control (ATC) Systems

ATC systems remain among the most critical and vulnerable components of aviation infrastructure. Threats such as denial-of-service (DoS) attacks, radio frequency interference, or exploitation of legacy systems can disrupt real-time coordination between pilots and ground staff. Miscommunication or delays in relaying flight instructions due to cyber incidents could lead to catastrophic results, including near-miss events or mid-air collisions. Testing for ATC systems must focus on communication protocol integrity, authentication mechanisms, and system resilience.

Ground Operations and Operational Systems

Cyber risks are not limited to what happens in the air. Systems supporting ground operations—such as flight management, crew scheduling, maintenance tracking, and fleet logistics—are frequent targets. Attacks on these systems can result in flight delays, cancellations, or even sabotage. Malicious actors can exploit misconfigured APIs, outdated software patches, or insecure access privileges. Cybersecurity testing must encompass these operational systems to prevent service interruptions and cascading failures across an airline’s operations.

Passenger-Facing Digital Infrastructure

Airline booking systems, mobile applications, digital kiosks, and frequent flyer programs are treasure troves of sensitive personal and financial information. These systems are often targeted by phishing campaigns, ransomware attacks, and fraud operations. Security testing for these digital touchpoints should include vulnerability assessments for input validation flaws (e.g., XSS, SQL injection), authentication and session management weaknesses, and encryption gaps in data storage and transmission.

Supply Chain and Third-Party Risks

The aviation industry’s dependence on a wide array of third-party vendors—including baggage handling, fueling, catering, and IT providers—has introduced the possibility of new vulnerabilities. Each vendor represents a potential entry point for attackers. Without stringent vendor security assessments and integration testing, attackers can compromise airline systems through weak links in the supply chain. Penetration testing, third-party audits, and continuous monitoring are crucial to mitigating these risks.

Aircraft-to-Ground Communication

Secure and uninterrupted aircraft-to-ground communication is vital for situational awareness and emergency handling. Vulnerabilities in satellite links, data uplinks, or control messages can be exploited to hijack communications or intercept sensitive data. Security protocols must be continuously tested to ensure they are robust against eavesdropping, jamming, and unauthorized command injections.

Building a Proactive Defense: Threat Intelligence and Testing

Aviation organizations must move beyond reactive defense mechanisms. Threat intelligence platforms should be integrated to provide real-time alerts on evolving threats. Cybersecurity testing must be proactive, continuous, and holistic—spanning from code-level application testing to red team assessments simulating real-world adversaries. This is supported by ongoing vulnerability scanning, compliance audits, cloud infrastructure reviews, and penetration tests across all operational tiers.
