China

Perspective

China's People's Liberation Army (PLA) has developed a strategy called "Integrated Network Electronic Warfare" which guides computer network operations and cyber warfare tools. This strategy helps link together network warfare tools and electronic warfare weapons against an opponent's information systems during the conflict. They believe the fundamentals for achieving success is about seizing control of an opponent's information flow and establishing information dominance.[5] The Science of Military and The Science of Campaigns both identify enemy logistics systems networks as the highest priority for cyberattacks and states that cyber warfare must mark the start of a campaign, used properly, can enable overall operational success.[5] Focusing on attacking the opponent's infrastructure to disrupt transmissions and processes of information that dictate decision-making operations, the PLA would secure cyber dominance over their adversary. The predominant techniques that would be utilized during a conflict to gain the upper hand are as follows, the PLA would strike with electronic jammers, electronic deception, and suppression techniques to interrupt the transfer processes of information. They would launch virus attacks or hacking techniques to sabotage information processes, all in the hopes of destroying enemy information platforms and facilities. The PLA's Science of Campaigns noted that one role for cyber warfare is to create windows of opportunity for other forces to operate without detection or with a lowered risk of counterattack by exploiting the enemy's periods of "blindness", "deafness" or "paralysis" created by cyberattacks.[5] That is one of the main focal points of cyber warfare, to be able to weaken your enemy to the full extent possible so that your physical offensive will have a higher percentage of success.

The PLA conducts regular training exercises in a variety of environments emphasizing the use of cyber warfare tactics and techniques in countering such tactics if it is employed against them. Faculty research has been focusing on designs for rootkit usage and detection for their Kylin Operating System which helps to further train these individuals' cyber warfare techniques. China perceives cyber warfare as a deterrent to nuclear weapons, possessing the ability for greater precision, leaving fewer casualties, and allowing for long-ranged attacks.

On March 2, 2021, Microsoft released an emergency security update to patch four security vulnerabilities that had been used by Hafnium, a Chinese nation-state-sponsored hacking group that had compromised at least 30,000 public and private Microsoft exchange servers.[6]

In September 2022, China's National Computer Virus Emergency Response Center (CVERC) accused the NSA of carrying out a series of cyberattacks against Northwestern Polytechnical University as part of tens of thousands of “malicious network attacks” that it said the agency conducted against Chinese targets.[7][8] The United States has said the university has conducted extensive military research and its department of Commerce has put the university on its entity list.[8]

In April 2025, CVERC said the information systems for the 2025 Asian Winter Games which it hosted were subjected to more than two hundred thousand foreign cyberattacks and accused the United States of being behind most of the attacks.[9] CVERC said that the attacks did not cause significant damage, and condemned cyberattacks targeting major international events.[10] The allegation were made in the midst of a trade war between the US and China and after the US accused Beijing of carrying out a cyberespionage campaign that targeted US-based critics of Beijing.[11]

Estonia

The 2007 cyberattacks on Estonia were a series of cyberattacks that began on 27 April 2007 and targeted websites of Estonian organizations, including Estonian parliament, banks, ministries, newspapers, and broadcasters, amid the country's disagreement with Russia about the relocation of the Bronze Soldier of Tallinn, an elaborate Soviet-era grave marker, as well as war graves in Tallinn.[12][13] The attacks triggered a number of military organizations around the world to reconsider the importance of network security to modern military doctrine. The direct result of the cyberattacks was the creation of the NATO Cooperative Cyber Defence Centre of Excellence in Tallinn.

Perspective

There were two such instances between India and Pakistan that involved cyberspace conflicts, starting in the 1990s. Earlier cyber attacks came to be known as early as 1999.[15] Since then, India and Pakistan were engaged in a long-term dispute over Kashmir which moved into cyberspace. Historical accounts indicated that each country's hackers have been repeatedly involved in attacking each other's computing database system. The number of attacks has grown yearly: 45 in 1999, 133 in 2000, 275 by the end of August 2001.[15] In 2010, Indian hackers laid a cyber attack at least 36 government database websites going by the name "Indian Cyber Army".[16] In 2013, Indian hackers hacked the official website of Election Commission of Pakistan in an attempt to retrieve sensitive database information.[17] In retaliation, Pakistani hackers, calling themselves "True Cyber Army" hacked and defaced ~1,059 websites of Indian election bodies.[17]

In 2013, India's Ministry of Electronics and Information Technology (MeitY) which was then known as Department of Electronics and Information Technology (DeitY), unveiled a cybersecurity policy framework called National Cyber Security Policy 2013 which officially came into effect on July 1, 2013.[18]

According to the media, Pakistan's has been working on effective cyber security systems, in a program called the "Cyber Secure Pakistan" (CSP).[19] The program was launched in April 2013 by the Pakistan Information Security Association and the program has expanded to country's universities.

In 2020, according to the Media reports, Pakistan Army confirms the series of Cyber Attacks that has been identified on Pakistani Government and private websites by the Indian Intelligence. ISPR also advised the government and private institutions to enhance cyber security measures.[20]
