What is the advantage of malware using APC $($asynchronous procedure call$)$ as a covert launching method?

a$)$ APC has a queue of events for implementation so any malicious process in the queue is mixed with the benign one.

b$)$ APC schedules the launch from the targeted thread rather than using CreateRemoteThread

c$)$ APC consumes less resources than process injection or replacement

d$)$ APC$$will automatically$$prioritize the execution of the malicious process if they are in the queue and flagged into an$$alertable state
