Sun Tzu wrote in his famous book, The Art of War, “If you know the enemy and know yourself, you need not fear the result of a hundred battles. If you know yourself but not the enemy, for every victory gained you will also suffer a defeat. If you know neither the enemy nor yourself, you will succumb in every battle.”


In the world of IT security, there are variety of players that are threat actors.  They cover a wide range of players that vary in sophistication and capabilities.  A threat actor or malicious actor is a person or entity that is responsible for an event or incident that impacts, or has the potential to impact, the safety or security of another entity.  Most often, the term is used to describe the individuals and groups that perform malicious acts against organizations of various types and sizes. From a threat intelligence perspective, threat actors are often categorized as unintentional or intentional and external or internal.


Hollywood has glamorized hacking and these threat actors, which often distorts the perception of them and the havoc they cause.  They are given hero like status when in fact they are creating destruction and chaos.  They should never be viewed in a positive light.

Preparing to defend your organization against a known antagonist is significantly easier and more effective than trying to defend yourself against the unknown. Here are a few profiles of current threat actors:


Script Kiddies – A script kiddie, or “skiddie,” is someone who lacks programming knowledge and uses existing software to launch an attack. Often a script kiddie will use these programs without even knowing how they work or what they do. For example, imagine a child gets their first computer. The child watches a movie about hacking and then downloads a copy of Kali Linux. They begin playing with the various programs while searching for online tutorials. At first, they may be perceived as nothing more than an internet troll or noob, due to their lack of experience and quickness to brag and boast. Sometimes they will even resort to cyberstalking or bullying. However , this may simply be a cover for other more nefarious activity.

Enthusiasts / Hobbyists – Not all hackers want to cause damage.  Some hackers are motivated by no more than curiosity.  They have a recreational interest in security and enjoy the intellectual challenge of breaking into networks.  This category has diminished in recent years as authorities have stepped up prosecution and legal action.

Top 5 threats actors

Insider Threat – Attackers operating inside your organization are typically disgruntled employees or ex-employees either looking for revenge or some type of financial gain. They sometimes collaborate with other threat actors, such as organized crime or government sponsored hackers, out of a sense of loyalty, or in exchange for money or prestige.

Opportunistic – These attackers are usually amateur criminals who are driven by the desire for notoriety. Sometimes, however, they can be legitimate security researchers trying to help organizations find and close security vulnerabilities, or even professional hackers (sometimes known as gray hat hackers) looking to profit from finding and exposing flaws and exploits in network systems and devices.


Internal User Error – Users making mistakes with configurations are actually the largest threat organizations face. These threat actors exist largely due to failing to design flaws out of the network, or by providing privileges to individuals who should not have them. Internal user errors have been known to bring down critical resources such as firewalls, routers, and servers, causing widespread or departmental company outages.


Hacktivists – These attackers have a political agenda. Their goal is to either create high-profile attacks that help them distribute propaganda, or to cause damage to organizations they are opposed to. The ultimate goal is to find a way to benefit their cause or gain awareness for their issue.

Organized Crime

Organized Crime – Most often, these cybercriminals engage in targeted attacks driven by profits. They are typically either looking for the personally identifiable information (PII) of your customers or employees, such as social security numbers, health records, credit cards, and banking information, or to hijack and ransom critical digital resources.

Nation-States – These groups are well funded and often build sophisticated, targeted attacks. They are typically motivated by political, economic, technical, or military agendas. They are often looking for competitive information, resources or users that can be exploited for espionage purposes.


Knowing your enemy can be vital when it comes to securing a corporation’s critical data, and applying threat intelligence with the different types of threat actors in mind is a crucial step to avoiding security breaches and minimizing the damage a breach can cause.

Additionally, with so many types of threat actors and potential motives and attacks, protecting against security threats requires a multi-pronged, continually evolving approach that involves diligent application and adherence to security best practices and policies — across the entire organization.
