Threat actor

Threat actor (or malicious actor) is an entity or individual that utilizes cyber attacks for malicious purposes. Threat actors can range from individual thrill-seeking hackers to state-backed espionage groups. Cyberattacks can encompass various malicious activities such as phishing, malware, denial of service (DoS), and ransomware.

A threat actor typically follows the intelligence cycle, a six-step process that allows them to assess a target and decide the most effective type of attack to use. This process consists of reconnaissance, the process of collecting information about the target; weaponization, the creation of malware or other tools to exploit the target; delivery, the process of using malicious files such as phishing emails or malicious websites to reach the targeted computer systems; exploitation, the process of executing arbitrary code to take control of a vulnerable system; installation, the process of installing backdoors or unauthorized processes; and command and control, the process of controlling the unauthorized access established by a threat actor.

Threat actors are notorious for using a variety of techniques such as social engineering to deceive their victims, making them targets for exploitation. They may also use exploit kits, coding frameworks that come with the necessary tools and instructions that allow malicious users to launch a full attack.

Threat actors evolved from opportunistic cyber criminals to organized criminal syndicates due to the availability of cheap, easy-to-use hacking tools. Cyberattacks are becoming more sophisticated and complex, with threats often targeting high-value corporate assets or government organizations.

Organizations can protect themselves against threat actors by implementing proper security measures, such as patching, user education, antivirus and anti-malware software, firewalls, and intrusion detection systems. Additionally, organizations should remain vigilant and continuously monitor their systems for threats. It is important to have a comprehensive security plan in place in order to identify and respond to threats quickly and effectively.
