Nation-state actors are typically known for having significant resources and funding, which allows them to conduct sophisticated and sustained cyber attacks. Such actors often engage in espionage or sabotage and have the capability to develop or purchase advanced tools and exploit zero-day vulnerabilities. Unskilled attackers usually lack the resources and capabilities to conduct complex attacks, while hacktivists and insiders might be able to execute sophisticated actions but generally do not have the level of resources comparable to nation-states. Organized crime groups can have considerable resources, but their activities often focus on financial gain rather than sustained complex attacks.
