Summary
Adds a new "Library/Module Loaded" subcategory under Process Activity in the macOS telemetry matrix. This tracks dylib/shared library load events, a key data source for detecting dylib hijacking, dylib proxying, and DYLD_INSERT_LIBRARIES injection.
The Windows matrix already includes "Image/Library Loaded" under Process Activity. This adds the macOS equivalent.
Current vendor support
event.category: libraryandevent.action: loadonlogs-endpoint.events.library*. Enabled by default when File event collection is active in the integration policy.Evidence
