Trend Micro Report Highlights Threat of Large-Scale Open Telemetry AI Fusion

A research report from Trend Micro's TrendAI warns that commercial open-source data is increasingly subject to large-scale automated harvesting and fusion. The report highlights an incident in February 2026 where entities used legally acquired public flight, maritime, and radio signals to reconstruct operational buildups prior to a military strike. Investigators also identified automated networks systematically accessing exposed software-defined radios, weather stations, and surveillance cameras. Tom Kellermann, Vice President of Threat Research at TrendAI, stated that adversaries no longer require internal network breaches when AI can synthesize public telemetry into detailed real-world operational intelligence. The report urges organizations to catalog exposed open telemetry, audit external signals across suppliers, and monitor commercial OSINT-fusion vendors.

Key takeaways

• TrendAI warns that public telemetry like flight data, beacons, radio signals, and cameras faces large-scale AI fusion risks.
• The report cites cases where entities reconstructed sensitive real-world operational contexts using only legal public data.
• Investigators detected automated relay networks continuously connecting to exposed software-defined radios, weather stations, and AIS gear.
• Trend Micro advises organizations to maintain open telemetry exposure registers and track OSINT-fusion entities within threat intelligence.
