What type of threat actors are MOST LIKELY to have a profit motive for their malicious activities?

Criminal syndicates may produce, sell, and support malware tools, or may deploy them themselves. Crypto malware and other packages are examples of tools often created and used by criminal syndicates. State actors are more likely to be associated with advanced persistent threats (APTs) aimed at accomplishing the goals of the nation-state that supports them. Hacktivists typically have political motivations, whereas script kiddies may simply be in it for recognition or fun.
