Half of Scanned GEO Satellite Links Were Unencrypted, Study Finds

ESA's CyberCUBE Satellite Opens an In-Orbit Testbed for Space Cyber Defenses

One Bug, Many Satellites: The Risk of Shared Flight Software
Small satellites increasingly run the same open-source flight and ground software, which means a single vulnerability can reach an entire fleet, from university cubesats to flagship missions.

Argo Brings Mathematical Proof to Satellite Cybersecurity

Distributing Ground Stations Adds Resilience and Cyber Attack Surface

Satellite Cybersecurity Act Clears Three Committees in Three Months

The Answer to GPS Spoofing: Authentication and Alt-PNT

One Bug, Many Satellites: The Risk of Shared Flight Software
Small satellites increasingly run the same open-source flight and ground software, which means a single vulnerability can reach an entire fleet, from university cubesats to flagship missions.

Spoofing the Strait: Electronic Warfare Broke Ship Tracking at Hormuz
Since February 2026, GPS and AIS spoofing across the Strait of Hormuz has become the longest sustained case of maritime electronic warfare on record.

Argo Brings Mathematical Proof to Satellite Cybersecurity
Atalanta has released Argo, the formal-methods tool used to harden Viasat after the 2022 AcidRain attack. It aims to prove a system is secure rather than hope it is.

Direct-to-Cell Satellites Inherit the Phone Network's Weaknesses
Starlink and AST SpaceMobile are putting LTE base stations in orbit so ordinary phones can connect. Research shows direct-to-cell carries the mobile network's known signaling weaknesses with it.

Distributing Ground Stations Adds Resilience and Cyber Attack Surface
US Space Command's call to distribute satellite ground stations answers a kinetic threat, but every new node, cloud interface, and commercial partner is another way in for attackers.

Satellite Cybersecurity Act Clears Three Committees in Three Months
The Satellite Cybersecurity Act of 2025 has now cleared three congressional committees in three months, putting a long-stalled satellite security bill closer to a Senate floor vote than it has ever been.
