Research flags plaintext traffic on GEO satellite links
Research published on June 18, 2026, reports that a significant share of GEO satellite traffic may be intercepted because it is sent in plaintext, using relatively accessible equipment.
Research published on June 18, 2026, reports that a significant share of traffic on geostationary (GEO) satellite links is transmitted in plaintext and may be intercepted with relatively accessible equipment. The available summary does not quantify that share or detail the equipment or methods used.
The text recommends that engineers responsible for satellite links check whether sensitive traffic is encrypted in transit. To verify the scope, methods, and findings, consult the original article and compare its evidence with the organization’s link configuration; do not assume that all GEO links have the same characteristics.
