Key Takeaways

  • Cyberwarfare refers to internet-based attacks on a nation’s government or military with the goal of causing disruption and damage. It’s distinct from cyberterrorism and cybercrime, though all three are closely related.
  • Attacks take many forms, including ransomware, DDoS attacks, espionage, propaganda and assaults on power grids. Understanding the different types helps organizations anticipate and prepare for potential threats.
  • Motivations range from military and political goals to financial gain and ideological activism. Hacktivism, while sometimes framed as protest, is still illegal regardless of intent.
  • No country or organization is immune, as high-profile attacks on governments and critical infrastructure around the world have shown. The consequences can range from operational disruption to physical destruction.
  • Organizations can reduce exposure through regular risk assessments, current security technology and skilled cybersecurity professionals. Proactive measures like threat hunting and supply chain risk mitigation are increasingly essential.

Cyberwarfare is an evolving and increasingly popular way of attacking a nation or country via the Internet — and the effects can be detrimental. In this guide, we’ll discuss the different types of cyberwarfare, examples of recent incidents and tips for how companies and organizations can protect themselves against these types of harmful attacks.

What Is Cyberwarfare?

Cyberwarfare is an internet-based attack on a nation or country’s government with the intention of causing disruption and damage. As Britannica explains, “cyberwar is usually waged against government and military networks in order to disrupt, destroy, or deny their use. Cyberwar should not be confused with the terrorist use of cyberspace or with cyberespionage or cybercrime.”

Cyberwarfare vs. Cyber War vs. Cyberterrorism 

Though all three are related, there are some distinct differences: 

  • A cyber war refers to the conflict itself, whereas cyberwarfare refers to the techniques and strategies used. 
  • Cyberterrorism is “the politically motivated use of computers and information technology to cause severe disruption or widespread fear in society.”
  • According to ScienceDirect “cyberwarfare differs from cyberterrorism as it is an organized effort by a nation state to conduct operations in cyberspace against foreign nations.”

Types of Cyberwarfare and Cyberterrorism Attacks

Cyberwarfare and cyberterrorism come in many forms. Here are some of the most common types, courtesy of Check Point and Imperva:

  • Economic disruption — In this type of attack, hackers specifically target computers and networks related to banks, stock markets or payment systems. 
  • Propaganda — This method involves spreading lies or exaggerated information so that people will question their country’s government and/or side with the antagonists.  
  • Attacking the electrical power grid — By disabling a power grid, hackers can wreak havoc on communications and bring massive disruption to a country’s infrastructure and access to essential services. 
  • Sabotage  — This includes leaking compromised information, making insider threats and targeting disgruntled government employees who are willing to carry out work against their own country. 
  • Espionage — This type of attack typically involves stealing another country’s secrets or classified information.
  • Distributed Denial of Service (DDoS) attacks — Hackers will overwhelm a website with spam requests in order to disrupt operations. This may also deny legitimate users access to critical services and support. 
  • Ransomware — A popular type of cyber attack, ransomware involves encrypting files or blocking computer access until the victim(s) pay a ransom to the hackers. 
  • Phishing — These types of attacks involve sending fraudulent communications, typically emails and text messages, that appear to come from a trusted source. The communication includes a link, which if clicked, can lead to the installation of malicious software or the beginning of a ransomware attack. 

What Is the Purpose of Cyberwarfare?

There are many reasons why hackers would engage in cyberwarfare. In a lot of cases, the reasons are military- or government-related with the goal of disrupting a country’s critical operations and infrastructure and/or gaining access to research and intelligence. 

Cyberwarfare may also be financially motivated, which is where ransomware often comes in. Another popular reason may be “hacktivism” — a combination of hacking and activism — that’s defined as “misusing a computer or the internet, primarily by way of hacking into unauthorized networks, to explore a believed injustice.” Hacktivisim may be politically, socially or religiously motivated. 

While some hacktivism attacks are not necessarily malicious, they are all still illegal. 

History of Cyberwarfare

The first mention of cyberwarfare was documented in 1987; according to Wired, a magazine article “described future wars fought with giant robots, autonomous flying vehicles, and autonomous weapon systems.” 

The idea of cyberwarfare evolved to later focus on computers and the rise of the Internet. An article published in 1993 by two employees at the RAND Corporation talked about hackers using military computers as a means of disruption; years later analysts at RAND realized that attacking non-military computers would be just as easy — if not easier.

Wired explains that the term was more clearly defined in the 2010 book “Cyber War,” co-authored by Richard Clarke, who served as the national security advisor to several U.S. presidents; and Robert Knake, who was a cybersecurity advisor to President Obama. They defined cyberwarware as “actions by a nation-state to penetrate another nation’s computers or networks for the purpose of causing damage or disruption.”

Examples of Cyberwarfare

The Center for Strategic & International Studies (CSIS) has a list of significant cyber incidents dating back to 2006, some of which include incidents of cyberwarfare. In November 2022, the United Arab Emirates recruited three former U.S. government officials to assist with breaking into computers in the United States and other countries. In the same month, hackers targeted the network of the Danish State Railways, which disrupted train operations for hours. 

Additional examples include: 

  • In 2010, “cyber attack on the Iranian nuclear fuel processing facility resulted in the physical destruction of almost 1,000 uranium enrichment centrifuges by the Stuxnet computer worm. The evidence points to the worm having been created by the United States and Israel in a collaborative effort known as Operation Olympic Games.” 
  • Russia has executed (or attempted to execute) numerous cyberwarfare attacks against Ukraine’s government. This list from CSIS details the most recent instances in 2021 and 2022. 

How to Combat Cyberwarfare 

In order to stay one step ahead of cyberwarfare attacks, companies and organizations should continually conduct risk assessments and audits. Additional measures should include:

  • Ensuring your organization has access to the latest security updates and technology.
  • Using best practices when it comes to cybersecurity (such as strong passwords, file encryption, authorized access, etc.) and conducting regular employee/organizational training. 
  • Employing cybersecurity experts and/or cybersecurity consultants who have the knowledge and experience to work on the front lines against hackers and combat potential threats. 
  • Other options include “threat hunting,” upgrading patch management processes and working to mitigate supply chain risks. 

frequently asked questions

Is cyberwarfare considered an act of war under international law?

Whether a cyber operation constitutes a prohibited use of force or an armed attack under international law depends on the circumstances, including the operation’s scale and effects. International law does not treat every malicious cyber operation as an act of war. Cyber operations that cause death, injury or physical destruction could clearly reach the threshold for the use of force, while the legal status of operations causing severe disruption without physical damage remains more contested. Espionage and other cyber operations may also violate international law without necessarily constituting a use of force or armed attack. The Tallinn Manual provides expert analysis of how existing international law applies to cyber operations, but it is a scholarly work and is not legally binding. 

What is attribution and why is it difficult?

Attribution is the process of determining who conducted a cyber operation, and it can be difficult because attackers can deliberately obscure their identity and route activity through compromised infrastructure. They may also use publicly available tools, steal another group’s malware or infrastructure or attempt to imitate another threat actor’s techniques. Analysts build attribution assessments from technical indicators, infrastructure, operational patterns and, when available, intelligence from other sources. Because the available evidence may be incomplete or classified, attribution assessments often involve varying levels of confidence rather than absolute certainty. Attribution can also serve different purposes, including technical incident response, intelligence analysis and determining whether a state may bear legal responsibility for an operation.

What are state-sponsored hacking groups?

State-sponsored hacking groups are threat actors that carry out cyber operations backed by a government or other state-linked entity. Some groups are associated with military or intelligence organizations, while others may involve contractors or criminal actors operating with varying degrees of state direction or support. Cybersecurity researchers often assign their own names to these groups because their actual organizational identities can be difficult to establish publicly. Researchers distinguish groups using evidence such as targeting patterns, infrastructure, malware, tools and operational techniques. As a result, the same group may appear under different names in reports from different security vendors.

Can private companies be targets of cyberwarfare?

Yes, private companies can be targets of state-sponsored cyber operations, particularly when they operate critical infrastructure, support government or military activities or provide access to other organizations. Energy companies, telecommunications providers, financial institutions, defense contractors and technology vendors may be targeted for espionage, disruption or access to their customers and partners. Supply chain attacks can extend the impact of an operation by compromising a vendor or software provider that serves many organizations. This is one reason national cybersecurity efforts often involve collaboration and information sharing between governments and the private sector.

What careers involve defending against nation-state threats?

Careers defending against nation-state threats include roles in government, the military, defense contracting and private-sector cybersecurity. Common positions include threat intelligence analyst, incident responder, malware analyst, detection engineer and security researcher. Government and military positions may involve eligibility requirements such as U.S. citizenship or a security clearance, depending on the position. Defense contractors may also have roles that require or prefer security clearances. Private-sector security companies and large technology organizations offer additional paths into threat intelligence, incident response and security research, although their requirements vary by employer and role.
