What Is Cyber Warfare?

Cyberwarfare refers to strategic cyber attacks aimed at a nation-state, causing significant harm such as disrupting vital computer systems or potentially resulting in loss of life. It involves actions by a nation or organization targeting the computer networks of countries or institutions to disrupt, damage, or destroy infrastructure using methods like computer viruses or denial-of-service attacks. Effective cyber threat intelligence tools are essential for reducing the impact of these attacks.

What Is Cyber Warfare

What Does Cyberwarfare Look Like?

Cyberwarfare manifests in various forms, all aimed at destabilizing or destroying critical systems to weaken the target country. This encompasses:

  • Targeting financial infrastructure
  • Attacking public infrastructure such as dams or electrical systems
  • Compromising safety infrastructure like traffic signals or early warning systems
  • Direct assaults against military resources or organizations


Cyberwarfare vs. Cyber War

Cyberwarfare and cyber war differ in their scopes: cyberwarfare typically denotes the tactics employed within a cyber war. For instance, a state-backed hacker might target the Bank of England as a cyber warfare tactic in the context of a conflict involving England and its allies.

What Are the Types of Cyberwarfare?


involves clandestinely gathering information from another country to acquire secrets. In cyberwarfare, this might entail utilizing methods such as botnets or spear-phishing attacks to infiltrate a computer system and extract sensitive data.


Once sensitive information is identified, organizations must assess potential threats to this data. This includes considering third parties seeking to steal the data, competitors aiming to gain an advantage through information theft, and insider threats such as disgruntled or negligent employees.

Denial-of-Service Attack

A denial-of-service (DoS) attack floods a website with bogus requests, overwhelming the site’s capacity and rendering it inaccessible to legitimate users. Such attacks could be employed to incapacitate critical websites used by citizens, military personnel, emergency responders, scientists, or others, disrupting essential operations or systems.

Electrical Power Grid

Hacking the electrical power grid could grant an attacker the ability to incapacitate vital systems, paralyzing infrastructure and potentially causing fatalities. Additionally, an assault on the power grid might disrupt communication channels, rendering services like text messaging or telecommunications unusable.


Propaganda attacks seek to influence the thoughts or loyalties of the populace within the targeted country. Propaganda may involve exposing embarrassing truths or spreading falsehoods to undermine trust in the government or even garner sympathy for the adversary.

Economic Disruption

Modern economic systems heavily rely on computer networks. Targeting economic facilities such as stock markets, payment systems, or banks through cyberattacks could provide hackers with access to funds or prevent targets from accessing necessary financial resources, impacting their ability to sustain themselves or engage in warfare.

Surprise Cyberattack

These cyberattacks aim to deliver a blow akin to Pearl Harbor or 9/11—sudden and devastating strikes that catch the enemy off guard, weakening their defenses. They could be employed to debilitate the opponent in anticipation of a physical attack, constituting a form of hybrid warfare.

Reasons and Motivations for Cyberwarfare


The military seeks to gain control over crucial aspects of an adversary nation’s cyberspace. A successful cyberattack could cripple the enemy’s military capabilities, securing a victory that might otherwise be costly.


Directly targeting a nation’s civil infrastructure affects its citizens, potentially instilling fear or provoking dissent against the government, thereby weakening the adversary’s political position.


Hacktivism involves using cyberattacks to advance an ideological agenda. Hacktivists may spread propaganda or uncover and expose secrets to undermine an opponent’s international standing, hindering support from other nations.

Income Generation

Individuals engaged in cyber warfare may do so for personal financial gain. If employed by a government, they might receive payment for their services. Alternatively, they could breach financial institutions’ defenses to steal money for themselves.

Nonprofit Research

Nonprofit research often uncovers valuable information that countries may exploit to address critical challenges. For instance, cyber warfare might involve stealing data related to a vaccine from a country that has already developed one, aiding another country’s efforts.

Examples of Cyber Warfare Operations

Below are some notable instances of cyber warfare in recent times that have garnered significant public attention:

Stuxnet Virus

Stuxnet, a worm that targeted the Iranian nuclear program, stands out as one of the most sophisticated cyber attacks to date. This malware, transmitted through infected Universal Serial Bus devices, specifically aimed at data acquisition and supervisory control systems. Reports suggest that it dealt a severe blow to Iran’s nuclear weapons manufacturing capabilities.

Sony Pictures Hack

Following the release of the film “The Interview,” which depicted Kim Jong Un unfavorably, Sony Pictures fell victim to a cyber attack attributed to North Korean government hackers. The FBI noted similarities between this attack and previous ones carried out by North Koreans, including shared code, encryption algorithms, and data deletion methods.

Bronze Soldier

In 2007, Estonia’s decision to relocate the Bronze Soldier, a statue associated with the Soviet Union, sparked a series of significant cyber attacks. Estonian government websites, media outlets, and banks were inundated with traffic, leading to widespread disruptions. These attacks, characterized by massive denial-of-service (DoS) assaults, occurred in the months following the statue’s relocation.

Fancy Bear According to CrowdStrike, the Russian cybercrime group Fancy Bear targeted Ukrainian rocket forces and artillery units from 2014 to 2016. The malware, distributed through an infected Android application used by the D-30 Howitzer artillery unit for managing targeting data, contained the X-Agent spyware. This attack is credited with causing substantial damage, resulting in the destruction of over 80% of Ukraine’s D-30 Howitzers.

Enemies of Qatar

In 2018, American Republican fundraiser Elliott Broidy sued the government of Qatar, alleging that it orchestrated the theft and dissemination of his emails to discredit him. Broidy claimed that Qatar viewed him as an obstacle to improving its reputation in Washington. The lawsuit implicated the brother of the Qatari Emir and other Qatari leaders in a cyber warfare campaign that targeted approximately 1,200 individuals, including prominent figures from Egypt, Saudi Arabia, the United Arab Emirates, and Bahrain, who were perceived as adversaries of Qatar.

How to Combat Cyber Warfare

The legal standing of this emerging domain remains uncertain due to the absence of international regulations governing the utilization of cyber weapons. Nevertheless, this ambiguity does not imply that cyber warfare operates outside the realm of law.

The Cooperative Cyber Defense Center of Excellence (CCDCoE) has released the Tallinn Manual, a guidebook that examines infrequent yet significant cyber threats. This manual delineates instances where cyber attacks contravene international law and outlines potential responses that nations can undertake in reaction to such breaches.

Conducting Risk Assessments with Cyber Wargames

Conducting real-life exercises or simulations, commonly referred to as cyber wargames, stands as the optimal method to evaluate a nation’s preparedness for cyber warfare.

These wargames serve to assess governmental and private sector responses to cyber warfare scenarios, identify vulnerabilities in defenses, and enhance collaboration among stakeholders. Most significantly, they enable defenders to develop swift response strategies to safeguard critical infrastructure and preserve lives.

Cyber wargames aid cities, states, or countries in enhancing their readiness for cyber warfare by:

  • Testing various scenarios, including early detection of attacks or risk mitigation post-compromise of critical infrastructure.
  • Simulating unconventional attack methods as real-world attacks seldom adhere to conventional tactics. By deploying a red team to simulate attackers and devise innovative strategies to breach target systems, defenders can learn to effectively counter genuine threats.
  • Facilitating division of labor and fostering cooperation mechanisms. Given that cyber warfare necessitates collaboration among individuals from diverse organizations and government units, cyber wargames offer a platform to bring together these stakeholders, fostering teamwork and decision-making during crisis situations.
  • Enhancing policies by subjecting them to practical testing. While governments may establish cyber warfare policies, cyber wargames offer an avenue to assess their efficacy and identify areas for enhancement.
