Vulnerability of Satellite Communication Links

Satellite links rely on radio frequency signals transmitted over long distances and are susceptible to eavesdropping, jamming, and spoofing attacks. Unlike terrestrial fiber, radio waves are inherently open and can be intercepted by adversaries with sophisticated equipment.

Physical Security Risks to Satellites

Satellites in orbit face threats from kinetic attacks (anti-satellite weapons), cyber intrusions on control systems, and space debris. Disabling or hijacking satellites can cause widespread network outages and compromise data security.

Potential Cyberattack Vectors

Signal Jamming and Spoofing

Jamming disrupts communication by flooding satellite signals with noise, while spoofing involves sending fake signals to deceive receivers. Both can degrade internet quality or allow attackers to redirect data.

Ground Station Compromise

Ground stations serve as critical hubs connecting satellites to terrestrial networks. Cyberattacks targeting ground station infrastructure can manipulate satellite control commands or intercept sensitive data.

User Terminal Exploitation

User terminals—small satellite dishes installed by consumers—are entry points vulnerable to malware, unauthorized access, and man-in-the-middle attacks.

Supply Chain Vulnerabilities

Space-based internet depends on complex global supply chains for hardware and software. Compromised components or firmware backdoors introduced during manufacturing pose severe security risks.
