Which of the following threat actors is the most likely to seek financial gain through the use of ransomware attacks?

Organized crime groups are primarily motivated by financial gain, making them the most likely threat actors to employ ransomware attacks. Ransomware directly extorts money from victims, aligning perfectly with their objectives. Insider threats are individuals within an organization who might cause harm, but their motivations vary and are not typically large-scale financial extortion via ransomware. Nation-state actors focus on espionage, sabotage, or political disruption, not usually direct financial gain through ransomware. Hacktivists are driven by ideological or political causes and use cyberattacks to promote their agenda, not typically for monetary profit.
