    Detects the creation and immediate deletion of a .dylib file within the 'Library/Application Support/updated/instances/' directory on macOS. This pattern is often associated with the ProRAM technique where a shared library is written to disk, loaded via dlopen, and quickly removed to evade static file-based detection.
