Organizations of all sizes are subject to cyberattacks. In a world with so many threats, preparation begins by knowing which cyberattacks are the most frequently used. Below are six of the most common cyberattacks or threats seen in 2024. 

  1. Ransomware/Extortion 
  2. Phishing/Social Engineering 
  3. Vulnerability Exploitation 
  4. Insider Threat 
  5. Denial of Service Attacks 
  6. Supply Chain Attacks 

While these cyberattacks are often considered separate incidents, they are frequently used together. A cyberattack typically consists of a series of behaviors, from initial access to achieving the threat actor’s end goal. This goal may vary based on the attacker’s motivation, which can be financial, personal, emotional, or political/ideological. The more emotional or ideological the motivation, the more determined an attacker is likely to be, often employing multi-stage tactics to reach their objectives. Multi-stage attacks can involve multiple strategies to carry out a larger operation. 

Common Attack Combinations 

Among the most common types of attacks, it is often understated that they are frequently combined to form a single, multi-stage attack. Phishing, for example, is often the root cause or initial access point. AI-driven phishing campaigns have become particularly dangerous, making these attacks more sophisticated and harder to distinguish from legitimate communications. The problem worsens when insider threats emerge. Insiders, such as employees, may sell or give away their access or even be paid to click on a phishing link, complicating matters as the threat originates from within the organization. 

Attackers may also exploit vulnerabilities to gain initial access or move through your network. This approach can serve various purposes, such as setting the stage for a ransomware attack. In 2024, denial of service (DoS) attacks have often been employed as part of a triple extortion scheme by ransomware groups to increase the likelihood of payment. DoS attacks are also used as distractions to divert attention from other nefarious activities occurring within the network. While the focus is on resolving the DoS attack, other malicious traffic may go unnoticed.  

Supply chain attacks, meanwhile, can either target your organization directly or use your business as a stepping stone to reach another intended target. Regardless of your position in the supply chain, the impact on your organization remains damaging. 

Early Detection is Key 

Early detection remains the best way to limit damages. The longer threat actors remain undetected, the more damage they can cause. Blocking initial access and restricting further access are critical measures for reducing the number of successful attacks. By identifying and closing the gaps where attackers may infiltrate, you can significantly reduce your risk. In areas that must remain open, ensure heightened detection measures are in place. 

Ultimately, cyberattacks are a series of behaviors strung together to meet a desired goal. The most common types of attacks can be combined into one major incident or broken down into smaller events. Regardless of the scale, organizations must keep their incident response plans up-to-date and regularly run tabletop exercises to practice mitigating these threats. This preparation can limit damages and shorten recovery time.
