Parent process is a technique used by malware to evade detection by security analysts. The parent process of a given process is the process that spawned it.
For example, most user processes on a Windows system have explorer.exe as their parent process. By checking the parent process of a given process, malware can determine whether it is being monitored …

Adversaries may spoof the parent process identifier (PPID) of a new process to evade process-monitoring defenses or to elevate privileges. New processes are typically spawned directly from their parent, or calling, process unless explicitly specified.
One way of explicitly assigning the PPID of a new process is via the CreateProcess API call, which supports a parameter that defines the …
Masquerading: Double File Extension
Adversaries may abuse a double extension in the filename as a means of masquerading the true file type. A file name may include a secondary file type extension that may cause only the first extension to be displayed (ex: File.txt.exe may render in some views as just File.txt).
