Cyber warfare refers to the use of digital attacks to harm a nation, organization, or individual by damaging or disrupting their computer systems, networks, or information. It can range from espionage and data theft to sabotage and even physical damage through hacking critical infrastructure.

Cyber warfare typically involves a state perpetrating cyber attacks on another. However, in some cases, the attacks are carried out by terrorist organizations and non-state actors seeking to further the goal of a hostile nation. There are several examples of alleged cyber warfare in recent history, but there is no universal and formal definition for how a cyber attack may constitute an act of war.

Types of cyber warfare attacks

Below are given some of the main types of cyber attacks.

Espionage

Refers to monitoring other countries to steal secrets. In cyber warfare, this can involve using botnets or spear phishing attacks To compromise sensitive computer systems before exfiltrating sensitive information. Usually, governments and organizations engage in cyber espionage to steal confidential information like military secrets, trade secrets, intellectual property, etc.

Cyber sabotage

This can involve sabotaging or disrupting critical infrastructure such as power grids, transportation systems, or financial networks. This can cause widespread chaos and damage to a state's economy and security.

Distributed denial of service (DoS attacks)

The use of botnets to bombard websites with fake requests is known as a DoS and it is designed to overwhelm systems and take critical operations or services offline.

Supervision

The use of digital propaganda, fake news, and other forms of information to pollute the target country’s media ecosystem can be viewed as a component of cyber warfare, particularly when done in tandem with other efforts to erode public trust in authorities and institutions and provoke social discord.

Inside jobs

Some of the most damaging cyber attacks can come from within. Hactivists, whistleblowers, and other domestic leakers can divulge sensitive information anonymously on the dark web unwittingly or intentionally.

Cyber warfare operations

Cyber warfare operations are offensive or defensive cyber activities carried out to protect national interests or harm another state. They are usually undertaken by military task forces or government-affiliated hacking groups.

Here are some high-profile examples of cyber warfare operations:

  • Stuxnet (2010) was the 1st cyber warfare tool intended to cause physical harm to infrastructure. Stuxnet was a malware cyber weapon that targeted Iranian nuclear centrifuges and caused substantial disruption to the country’s nuclear program.

  • Cyber espionage by the US in 2013 against Such as Brazil and Germany was revealed in documents leaked by Edward Snowden.

  • The Sony Pictures hack in 2014 saw a state-affiliated hacking group from North Korea leak confidential documents belonging to Sony Pictures. The attack was in response to the release of the interview a Hollywood full film portraying North Korea in an unfavourable light.

  • Wannacry 2017 was a ransomware attack originating from North Korea. Wannacry exploited a Windows vulnerability to revoke data access across hundreds of thousands of PCs in 150 countries.

  • Blackouts in Mumbai, India 2020 are thought to have been part of a Chinese cyber-attack conducted as a warning against India.

  • The Russian invasion of Ukraine from 2022 to the present has seen an unprecedented escalation in digital warfare. As well as, the ongoing physical conflict, the use of wiper malware targeting Ukrainian organizations has been widespread.

How do countries defend themselves against cyber warfare?

To protect against cyber warfare, government and high-profile organisations invest in advanced cybersecurity tools, processes, policies, and highly specialized teams dedicated to securing devices and networks. These include antivirus software, endpoint protection, VPNs, and other data encryption technology. Another tool is intelligence research conducted by cybersecurity companies and intelligence agencies to identify potential attack vectors and new threat trends.

Governments also use proactive practices such as penetration testing and ethical hacking to stay ahead of adversaries. Ethical hacking involves authorized hacker types simulating what might happen in the event of a real attack to highlight vulnerabilities that can then be addressed and fixed. Penetration testing is similar but it is performed to a more specific brief and scope. In the US, a regular hack the Pentagon exercise sees the Department of Defense and hacker one work together to mobilize freelance and amateur ethical hackers as part of a crowdsourced national security initiative this type of program is designed to identify and fix bugs in the department's public websites has also been adopted by the UK's ministry of defence and Singapore's government technology agency.
