Detects the creation of image files (.bmp, .png, .jpg, .jpeg) by processes executing from non-standard directories such as AppData or ProgramData. This behavior is indicative of unauthorized screen capture activities often used by malware for pattern-of-life monitoring, where screenshots are staged in temporary locations before exfiltration. The rule filters out common legitimate applications known to perform screen captures.
