Abstract

The digital landscape has increasingly become a battleground for geopolitical tensions. Among the most significant of these conflicts is the cyber warfare between China and India. This article delves into the data surrounding cyber-attacks between these two nations, analysing patterns, motivations, and impacts. The study leverages data from cybersecurity firms, government reports, and open-source intelligence (OSINT). 

Through a comprehensive examination of the last 30 years, we aim to provide insights into the evolving nature of cyber conflicts, their correlation with geopolitical events, and potential strategies for mitigation. The report also provides predictive insights into future trends and offers policy recommendations to strengthen national cyber defences.

Introduction

Cybersecurity threats have become an integral aspect of modern conflicts. India and China, as two of Asia’s largest economies and political powers, have witnessed numerous cyber confrontations over the past two decades. The nature of these attacks ranges from state-sponsored espionage to hacking groups targeting critical infrastructure. With the rapid digitisation of both nations, the scale and sophistication of these cyber incursions have dramatically increased. Cyber warfare has emerged not only as a tool for espionage but also as a means to exert economic pressure, disrupt social stability, and influence geopolitical narratives.

India’s digital transformation, marked by initiatives such as Digital India, has expanded the country’s technological footprint but also increased vulnerabilities. Similarly, China’s aggressive technological growth and cyber capabilities, led by its military and government agencies, have raised global concerns about cyber espionage and cyber warfare. The cyber domain has effectively become the new frontier of Indo-China rivalry, where borders are invisible, and the damage can be catastrophic.

Volume of Cyber Attacks (2005-2025)

Between 2005 and 2010, cyber incidents between China and India were sporadic, largely limited to small-scale website defacements and low-level phishing attempts. However, post-2010, with the rise of state-sponsored Advanced Persistent Threat (APT) groups, these attacks became systematic and highly targeted. The development of dedicated cyber divisions within military and intelligence agencies in both nations contributed to the intensification of cyber conflicts.

Key Findings:

• 2005-2010: Fewer than 50 incidents per year, primarily website defacements and phishing.
• 2011-2015: A sharp increase to an average of 200 incidents per year, with the introduction of espionage operations and the compromise of Indian defence networks.
• 2016-2020: A dramatic escalation to over 700 incidents per year, including critical infrastructure targeting such as power grids and telecommunications networks.
• 2021-2025: Stabilisation at around 600-650 incidents annually, indicating ongoing but more covert state-sponsored activities focusing on cyber espionage and sabotage.

This steady escalation demonstrates the evolution from amateur attacks to strategic cyber operations that align with geopolitical developments.

Attack Categories

Cyber-attacks between China and India were categorised into four primary sectors:

• Espionage (60%) – Cyber espionage remains the dominant form of attack, focusing on stealing sensitive data from government, military, healthcare, and corporate targets. Notable campaigns include theft of defence plans, missile technology blueprints, and vaccine research data.
• Critical Infrastructure Attacks (20%) – These include attempts to infiltrate and disable power grids, nuclear facilities, communication networks, and transportation systems. Cyberattacks on Indian power infrastructure in Mumbai in 2020 are a prime example.
• Financial Systems Targeting (10%) – These attacks aim at disrupting banking systems, stealing financial data, manipulating digital transactions, and interfering with fintech startups. India has reported numerous cases of payment gateway breaches traced back to Chinese IP addresses.
• Defacement & Hacktivism (10%) – Hacktivist groups deface websites and release sensitive data to make political statements. Government portals, media outlets, and educational institutions have been frequent targets.

Top Sectors Targeted in India:

• Defence & Aerospace: 35%
• Energy & Utilities: 25%
• Banking & Finance: 15%
• Healthcare: 10%
• Government Services: 15%

These sectors represent the backbone of national security and economic stability, making them prime targets for cyber adversaries.

Major Cyber Incidents Timeline

The following timeline highlights significant cyber incidents between China and India:

Year	Incident	Impact
2010	Operation Aurora	Theft of sensitive data from Indian defence contractors and government agencies
2015	Chennai Power Grid Attack	Power grid malfunction for 2 hours, causing regional blackouts, suspected Chinese origin
2020	Mumbai Power Outage	12-hour blackout affecting millions, attributed to malware planted in power control systems
2023	COVID-19 Research Espionage	Theft of Indian vaccine research data by suspected Chinese APT groups

These events illustrate the increasing boldness and sophistication of cyber threats emanating from China, often aligned with diplomatic standoffs or military tensions.

APT Groups Involved

Several Chinese APT groups have been identified as active in cyber operations against India:

• APT10 (Stone Panda) – Known for long-term espionage campaigns targeting defence, aerospace, and healthcare sectors.
• APT41 (Double Dragon) – Operates with dual motives: state-sponsored espionage and personal financial gain through cybercrime.
• RedEcho – Specialises in attacks on India’s critical infrastructure, notably power grids and utilities, during geopolitical crises.

India’s counter-cyber operations have intensified in recent years with:

• NTRO (National Technical Research Organisation) – Handles cyber intelligence gathering.
• CERT-IN – Provides incident response, monitoring, and threat mitigation services.
• Private Cybersecurity Firms – Companies like Quick Heal and K7 Labs assist in building national cyberdefence capacities.

Tactics, Techniques, and Procedures (TTPs)

Common TTPs used in these cyber conflicts include:

• Spear Phishing (70%) – Using fake but convincing emails to gain initial access into secure networks.
• Zero-Day Exploits (15%) – Exploiting software vulnerabilities unknown to the vendor.
• Malware Deployment (10%) – Utilising Remote Access Trojans (RATs), ransomware, and spyware to gain control over targeted systems.
• Supply Chain Attacks (5%) – Compromising third-party software providers to access the main targets, as seen in recent Indian telecom sector breaches.
