Execution of Suspicious File Type Extension
Detects whether a process is created from an image path that does not have a standard executable file extension (e.g., .exe, .com, .bin). This behavior can indicate advanced evasion techniques like process ghosting or other unorthodox methods to launch processes, where an executable might be disguised or loaded without a typical extension. The rule includes various filters to reduce false positives from legitimate system processes, temporary files, installer components, and specific third-party applications.
