T-Minus Space Daily: Lessons from the Viasat Cybersecurity Attack

Episode Overview: In the November 30, 2024 episode of T-Minus Space Daily, hosted by Maria Varmazas from N2K Networks, the discussion centers on the significant cybersecurity breach against Viasat’s Kasat satellite network. The episode features Clemence Poirier, a senior cyber defense researcher at the Center for Security Studies at ETH Zurich, who delves into the ramifications of the attack and its broader impact on the space sector.

1. Introduction to the Viasat Cybersecurity Attack

The episode begins with Maria Varmazas outlining the context of the Viasat attack. On February 24, 2022, just hours before Russia's invasion of Ukraine, Russia's military intelligence launched a cyberattack targeting Viasat’s Kasat satellite network. This breach disrupted satellite communications for the Ukrainian armed forces, severely hindering their ability to respond to the invasion.

2. Clemence Poirier’s Background and Study

Clemence Poirier introduces herself, highlighting her role as a senior cyber defense researcher at ETH Zurich and her focus on cybersecurity in outer space. Her prior experience includes a research fellowship with the French space agency, CNES, at the European Space Policy Institute in Vienna. Poirier has authored a comprehensive report titled "Hacking the Cyber Operations against the Space Sector," examining the Viasat attack and its aftermath.

3. Evolution of Cybersecurity Awareness in the Space Sector

Poirier explains that before the Viasat attack, cybersecurity was largely neglected within the space sector. This oversight extended across engineers, industry stakeholders, and public policy frameworks. The Viasat incident served as a "wake-up call," prompting increased scrutiny and awareness regarding cybersecurity vulnerabilities in space systems.

Clemence Poirier [03:43]: "Prior to the Viasat attack, there was very little interest from the space sector for cybersecurity issues. It was somewhat overlooked by engineers, the industry, and public policies."

4. Mapping Cyber Operations Against the Space Sector

Timestamp [07:07]

Poirier conducted an extensive analysis of cyber operations targeting the space sector during the Ukraine conflict. By monitoring various online platforms, including Telegram channels, Twitter accounts, and hacker forums, she identified 124 cyber operations aimed at the space sector. These operations were primarily conducted by groups aligned with the conflict, often labeled as hacktivist groups.

Key Findings:

• Diverse Attacks: The majority of attacks were distributed denial-of-service (DDoS) attacks targeting websites, space agencies, and authentication portals of space services like Starlink.
• Lack of Specialization: No single group specialized exclusively in targeting the space sector. Instead, attacks were part of broader campaigns against specific countries.
• Technical Challenges: Many attackers acknowledged the complexity of hacking satellite networks, indicating a significant knowledge gap in cyber operations targeting space systems.

Clemence Poirier [10:24]: "There are no groups that are specialized or entirely dedicated to targeting the space sector. All the cyber operations I could find were random, almost among bigger campaigns against specific countries."

5. Nature of the Attacks: Sophistication and Impact

Poirier contrasts the initial sophisticated Viasat attack with subsequent less complex operations. While the Viasat breach involved multiple stages, including DDoS and malware deployment, later attacks were mostly unsophisticated DDoS assaults. Despite their simplicity, these attacks had tangible impacts, such as disrupting Starlink’s authentication portals, thereby denying users access to crucial connectivity services.

Additional Insights:

• Intrusions and Data Breaches: A smaller fraction of attacks involved direct intrusions into satellite networks and data breaches, though evidence of wiper malware was scarce.
• Attack Focus: Most cyberattacks targeted the ground systems and user interfaces rather than satellites in orbit, underscoring the vulnerability of terrestrial components in space systems.

Clemence Poirier [16:26]: "I could not find any example of a cyber attack targeting the satellite in orbit directly. All the cyber attacks were targeting the user segment, the ground segment, or what I call the user interface."

6. Implications for the Space Sector

Timestamp [17:01]

Poirier discusses the critical lessons for the space industry:

• Broadened Threat Models: The space sector must expand its threat models to account for the evolving landscape of cyber threats, recognizing that both civilian and commercial entities are prime targets.
• Focus on Ground Systems: Enhanced security measures should prioritize protecting ground-based infrastructure and user interfaces, which are more susceptible to attacks.
• Adapted Cybersecurity Solutions: Traditional cybersecurity measures may be inadequate for space environments. There is a burgeoning need for space-specific cybersecurity solutions that consider unique challenges such as radiation, extreme temperatures, and long-distance operations.
• Regulatory Developments: Current regulations do not mandate cybersecurity implementations for space operators. However, new directives like the EU’s NISTU are beginning to recognize space as critical infrastructure, necessitating stricter cybersecurity protocols.

Clemence Poirier [17:01]: "The space sector has to broaden its threat model and that the threat model changes rather quickly. Whenever you have a new customer or one of your old customers gets involved in an armed conflict, you are going to be attacked."

7. Future Outlook and Industry Recommendations

Poirier emphasizes the importance of proactive measures:

• Industry Collaboration: There needs to be a concerted effort between state entities and industry players to develop and implement effective cybersecurity strategies tailored for space systems.
• Emerging Market Opportunities: The rise of startups specializing in space cybersecurity presents opportunities for innovation and strengthening the sector’s defenses.
• Regulatory Compliance: As new laws and directives are adopted, space operators must ensure compliance and integrate robust cybersecurity practices to safeguard their assets and services.

Clemence Poirier [17:01]: "There is an arrear of knowledge that still needs to be developed with new solutions that are truly adapted to the systems. This is something that we see emerging."

8. Conclusion

The episode concludes with Maria Varmazas highlighting the significance of Poirier’s findings, underscoring the urgent need for the space sector to enhance its cybersecurity framework. By addressing vulnerabilities in ground systems and embracing specialized cybersecurity solutions, the industry can better protect itself against evolving cyber threats.

Maria Varmazas [23:30]: "It's fascinating that you've identified that there's that knowledge gap, both in terms of the defenders that the market can benefit from with the growing space cyber market... But it is fascinating to see people are going to go after the easiest targets first and ground systems and ground-based infrastructure is still the easiest. So that's what they're going to go for."
