What it detects
This rule flags process creation events where the executed binary matches UltraViewer Desktop components, identified by product, company, and original filename. Attackers can use legitimate remote access software to establish interactive control over systems, blending into expected administrative or support tooling. The detection relies on Windows process creation telemetry and specific executable metadata (Product, Company, and OriginalFileName).
