Monthly Expert Segment: Cybersecurity & Space with Brandon Karpf [10:46–22:13]
Prediction: Imminent Rise in Satellite Infrastructure Attacks
- Escalating Threats and Preparation for Attacks:
- Brandon Karpf predicts clear evidence "within the next 12 months" of adversaries preparing large-scale attacks against satellite infrastructure, potentially on par with or exceeding the Viasat hack.
"We are going to see clear evidence of preparation for another Viasat-level hack, an attack against satellite infrastructure."
— Brandon Karpf, [11:04]
-
Geopolitical Context:
- Increased Russian aggression in Eastern Europe: incursions with drones, missiles, manned aircraft.
- Russia’s demonstrated ability to coordinate cyber and physical attacks, as shown in previous events (e.g., Viasat).
- Breakdown in dialogue between Western nations and Russia amid escalating rhetoric.
-
Alarming Numbers: Anti-Satellite Weapons in Orbit
- Canadian Space Forces’ Brigadier General Christopher Horner reports tracking “potentially more than 200 anti-satellite weapons currently in orbit.”
- Both the French and Canadian space military leaders warn of a rapidly worsening threat environment.
"Canada's space leader... revealed that they are tracking at least potentially more than 200 anti satellite weapons currently in orbit, which is a scary number."
— Brandon Karpf, [13:37]
"If you had asked me how many ASAT weapons do I think are in orbit, I would not have come up with 200. Not even close."
— Maria Varmazas, [14:12]
What Should the Community Do?
-
Key Threat Factors:
- Russia’s active jamming of GPS signals in Eastern Europe.
- Significant presence of Russian ASAT weapons.
- 120% increase in cyber intrusions against space infrastructure over the past year ([17:34–17:57]).
-
Call to Action:
- Urgent need for "shields up" mentality among governments and especially businesses.
- SMEs in defense and aerospace particularly vulnerable due to tech debt and unpatched systems.
-
Exploits and Vulnerabilities:
- Recent Cisco ASA exploit exposure is especially relevant for space-adjacent companies using edge devices for network security ([15:30–16:30]).
- Potential for adversaries to leverage these vulnerabilities for persistent access and offensive cyber operations against satellite ops.
Business & Technology Implications
- New Technologies for Defense:
- Importance of digital twins, secure comms, zero trust, low-latency optical networks, and self-healing satellite architectures.
"This is really a call to action, to the community, to get together now. It's also a business opportunity."
— Brandon Karpf, [18:49]
- Signs of Battlespace Preparation:
- Reconnaissance behaviors and attempts to access critical network segments/signs of staged malware should be treated as early warning ([19:27–21:03]).
Sector-Wide Coordination Needed
- Not Just a Military Story:
- Civilian and commercial space operators—especially those supporting constellations, data relay, and Earth observation—must heighten vigilance.
- Threat actors are already moving beyond intelligence-gathering to potentially preparing destructive malware.
"Businesses need to stand up and take notice. Although it is fascinating to think, if not in a good way, if Russia already potentially has a foothold somewhere, then you've got to try and figure out who's in your network right now. That is not an easy thing to do."
— Maria Varmazas, [16:52]
Notable Quotes & Memorable Moments
On the surge in ASATs:
"Canada's space leader... revealed that they are tracking at least potentially more than 200 anti satellite weapons currently in orbit, which is a scary number."
— Brandon Karpf, [13:37]
The new threat reality for businesses:
"Types of businesses that are in the defense and aerospace domain, especially industries and businesses with some tech debt... This is a critical vulnerability."
— Brandon Karpf, [15:51]
A clarion call across the community:
"This is really a call to action, to the community, to get together now... anyone who's working on things like digital twins, secure communications, zero trust architectures..."
— Brandon Karpf, [18:49]
On public-private vigilance:
"Not all of those [cyberattacks] are necessarily preparation of the battlespace... but the situation can tip very quickly from initial access into preparing the battlespace."
— Brandon Karpf, [18:03]

- The cyber and physical battlespace in orbit is heating up, with nation-states like Russia preparing for escalations beyond the Ukrainian theater.
- Defenders—especially in the commercial sector—must not assume attacks are solely a military concern but recognize that their systems are key targets for disruption or destruction.
- Proactive security measures, technology upgrades, and greater public-private collaboration are urgently needed.
- The next 12-18 months are poised to be especially fraught with heightened risks and require vigilance from everyone involved in the global space and cybersecurity communities.
