Profiling Cyber Adversaries and Their Tactics

Cyber threats have become a critical component of our digital world. From state-sponsored hackers to rogue individuals, corporate spies, and organized crime units, these threat actors come in many forms and possess the skills and capacities to wreak havoc on our online infrastructure. Motivated by various objectives, such as financial gain or espionage, threat actors employ a complex array of Tactics, Techniques, and Procedures (TTPs) for their attacks. These tactics may include anything from phishing campaigns, malicious software, social engineering, and network intrusions to data manipulation or theft.

In this chapter, we will discuss the motivations and objectives of threat actors and explore some real-world examples of cyber-attacks. We will also look at the different types of TTPs used by threat actors and evaluate measures that can be taken to protect against them. Ultimately, the goal is for you to gain a better understanding of cyber threats and the actions necessary to secure your systems against malicious actors.

We will cover the following topics:

Types of threat actors

Motivations and objectives of threat actors

Tactics, Techniques, and Procedures (TTPs)

Real-world examples of cyberattacks and consequences

Types of threat actors

It is time for the next change in how security professionals approach not only building defenses but best practices for identifying, responding to, sustaining, and recovering from attacks. While, historically, it was all about building preventative defenses and even often assuming that the organization would never be targeted, at one point, it was understood that organizations must continuously assume breaches. By assuming breaches, organizations prepare for the worst-case scenario because it is acknowledged that it’s no longer if but when they will be targeted. However, now we must go to the next step, assume an attacker’s mindset, and anticipate their next move while becoming more resilient. As seen in the following figure, as an industry, it’s time to push into the stage of anticipation.

Figure 1.1 – Evolution of cybersecurity mindset

Putting oneself in the attacker’s mindset is crucial as it allows for building effective incident response procedures, which can help ensure that all necessary steps are taken immediately following an attack. Furthermore, proactive measures such as implementing robust security controls, conducting continuous threat and vulnerability assessments, training security and end users on cyber hygiene best practices, and regularly testing your incident response plans are essential to any organization’s modern cybersecurity strategy. However, all this can only be possible If we deeply understand the threat actors and the landscape. Remember that threat actors are also putting themselves into a defender’s mindset and consider how incident response procedures might be modeled, the tooling you might have and how it’s configured, and respective Service-Level Agreements (SLAs) with stakeholders. As defenders, we must understand who we are against; this will help us prioritize our defense strategy. Just as a chess player must study their opponent’s moves to plan a winning strategy, defenders must understand their adversaries to prioritize their defense tactics effectively.

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. ― Sun Tzu, The Art of War

Cybersecurity threats can be posed by a group or individual, including nation-state threat actors, hacktivists, cybercriminals, script kiddies, and Advanced Persistent Threat (APT) actors. Each type of threat actor has motivations and objectives in launching attacks against organizations or individuals. First, security professionals must understand the different kinds of threat actor categories so that, in the next step, it’s possible to understand the TTPs used to attack systems and the potential consequences should the threat actor be successful. When diving into the different kinds of threat actors, it is critical to understand their unique motives, their available resources, and the methodology they use for their cyber attacks. Not all attacks are equal, and not all security controls will be adequate for all attacks.

Summary of threat actor categories

Each type of threat actor presents unique challenges and requires tailored defense, identification, response, and recovery strategies to mitigate the risks they pose effectively. Therefore, let’s dive deeper into each of these threat actor types.

Cybercriminals

Cybercriminals continuously hunt for vulnerabilities that can be exploited to gain unauthorized access to sensitive data, often for financial benefits. Cybercriminals manifest in different types, from individual cybercriminals who typically aim to compromise individual accounts to crime syndicates with an extensive global reach. Cybercriminals commonly leverage phishing campaigns, identity theft, and ransomware attacks to steal valuable information or extort money from their victims. As cybercriminals evolve and adapt, cybercriminals employ increasingly sophisticated techniques and tools to compromise security controls and penetrate personal and organizational systems. Some cybercriminals target vulnerable small businesses, while others seek to infiltrate large corporations, government agencies, or critical infrastructure.

Nation-state actors

Nation-state threat actors are among the most feared threat actor categories. The reason is that nation-state actors, the majority of the time, have significant resources to plan and execute large-scale and highly sophisticated cyber attacks. The majority of the threat actor groups that are sponsored by governments or state-affiliated entities operate in the shadows in complete secrecy and aim to steal sensitive information, disrupt critical infrastructure, or conduct cyber espionage operations. It’s crucial to not take nation-state actors lightly due to their access to significant resources and vast networks, allowing them to launch massive global campaigns against any target quickly.

Hacktivists

Hacktivists, also called cyber activists, are not a new threat actor category but have existed since 1996. In 1996, Cult of the Dead Cow (CDC) members coined the term hacktivism. The CDC was an early hacktivist collective that exposed government secrets and fought for freedom of speech on the internet. Hacktivists use hacking techniques to promote social or political causes. Their victims are organizations and governments that hacktivists deem unjust, to bring attention to their cause.

A hacktivist group example is Anonymous, which has performed several cyberattacks over the years, including an operation against Scientology
