Detects instances where the Windows Search Indexer service process (SearchIndexer.exe) performs suspicious process-related API calls such as memory writes, remote thread creation, or opening processes against common web browser executables (chrome.exe, msedge.exe). This behavior is characteristic of malicious process injection where a legitimate, high-privileged system process is abused to inject code into a browser process.
