Operation Bunyanun Marsoos | Pakistan’s Military and Cyber Attack on India Explained (May 2025)

Key takeaways

• Separate confirmed events from unverified claims, especially when cyber attacks are reported in a war context.
• Hacktivist defacements and DDoS attacks are common during conflicts but often have limited real impact.
• Check CERT-In advisories for official guidance during incidents.

Introduction to Operation Bunyanun Marsoos

Operation Bunyanun Marsoos was a large-scale military and cyber attack launched by Pakistan on May 10, 2025, following India’s Operation Sindoor, a retaliatory mission after the Pahalgam terror attack in Kashmir. The operation revealed a new-age warfare approach involving missiles, drones, and cyber strikes aimed at weakening Indian defense infrastructure and public systems.

What Triggered Operation Bunyanun Marsoos?

The catalyst for this operation was India's midnight air and drone strikes on four major Pakistani Air Force bases, carried out after the Pahalgam terror attack that killed 26 Indian civilians. Pakistan responded aggressively with Operation Bunyanun Marsoos, positioning it as a counter-offensive to India’s actions.

Pakistan’s Military Strikes on India

Pakistan launched a coordinated attack using fighter jets, drones, and surface-to-surface missiles, targeting Indian military and logistical installations.

Which Key Indian Military Targets Were Hit?

These military attacks were aimed at damaging India's defensive capabilities and reducing its ability to retaliate.

Massive Cyber Attacks on India

Alongside its physical attack, Pakistan executed a major cyber warfare operation targeting Indian government, military, and civilian infrastructure.

Cyberattack Impact Summary

The use of malware, phishing, and ransomware crippled systems and triggered mass panic.

Malware Campaign: Cyber Weapons in Use

Indian intelligence agencies detected fake files and Trojan programs disguised as useful software. Two of the most dangerous malware files were:

• tasksche.exe

• "Dance of the Hillary"

These files were designed to trick users into clicking, leading to system compromise, data leaks, or ransomware infection. Users were urged to stay alert and avoid unknown links.

What Was India’s Response to Operation Bunyanun Marsoos?

India responded by putting all three armed forces on high alert and strengthening border surveillance. Cyber defense teams were activated, and emergency protocols were launched to recover affected systems.

International Reactions

What Is the World Saying?

• The USA, G7 nations, and Saudi Arabia have urged both countries to resolve their issues peacefully.

• The UN Security Council expressed concern over the scale and technology used.

• Fear of escalation into a nuclear conflict is growing if dialogue fails.

Why Operation Bunyanun Marsoos Matters

This operation highlighted how cyber warfare is now as dangerous as traditional war. The blending of physical attacks and cyber sabotage marks a turning point in how future conflicts may unfold.

Lessons for Cybersecurity in India

What We Must Learn

• Cyber awareness is critical at both government and individual levels.

• Strengthening public infrastructure and internet hygiene is now a national priority.

• Public must avoid clicking on unknown attachments or software like tasksche.exe or suspicious email links.

Conclusion

Operation Bunyanun Marsoos is a strong reminder of modern threats. From missiles to malware, the battlefield is everywhere. India, and every citizen, must now focus on being cyber aware, technologically prepared, and vigilant in the digital world.
