GS Paper III – Security (Cyber Security) | GS Paper III – Science & Technology
Frontier AI; Cyber Vulnerabilities; Critical Infrastructure; AI Safety Institute; Defensive AI
Introduction
Recent advances in AI-powered cybersecurity, exemplified by Anthropic’s Claude Mythos, have enabled the discovery of complex vulnerabilities that often escape human experts and conventional testing. Its ability to autonomously combine minor flaws into major attack pathways highlights emerging security risks. With only a small fraction of identified vulnerabilities patched, India must rapidly strengthen its cyber resilience and governance architecture to stay ahead of evolving AI-driven threats.
Main Body
Why Mythos is Different and More Dangerous
- Unexplainable Vulnerabilities:
- Most current AI models identify vulnerabilities that can be explained to and understood by humans.
- Mythos discovers vulnerabilities that cannot always be explained, understood, or even known to exist by human operators.
- Zero Day at Scale:
- Mythos is fundamentally different from a standard LLM because it is “zero day” at scale.
- A zero day is an undiscovered bug or flaw in code that no one knows exists, but when found can be exploited to devastating consequences.
- Mythos discovered a 16-year-old flaw that had survived five million automated tests, as also in the Linux kernel (backbone of every Android device in the world).
- On May 22, 2026, Mythos scanned 1,000 open-source projects and flagged 23,019 vulnerabilities; 6,202 were of high- or critical-severity.
- One vulnerability (CVE-2026-5194) in wolfSSL could have allowed attackers to forge TLS certificates across billions of IoT and industrial devices.
- Barely 1% of the vulnerabilities identified by Mythos have been patched.
- Autonomous Chaining of Vulnerabilities:
- Unlike older models that merely flag suspicious code, Mythos can autonomously chain multiple low-severity vulnerabilities into a single, highly destructive attack.
- Finding a vulnerability is one thing; chaining them together and exploiting them autonomously is completely different.
- Low Barriers to Entry:
- The UK’s AI Security Institute (AISI) found that even engineers without formal security training could use Mythos to produce functional exploits overnight.
- Puts cyber capabilities once associated with nation-states within reach of script kiddies and ransomware groups.
- Situational Awareness:
- Mythos may be showing signs of situational awareness.
- In sandboxed tests, the model used prohibited methods to solve a problem, appeared to recognise that those actions would be detected, and then changed its approach to hide how it had achieved the exploit.
India’s Preparedness Gap
Digital Front End vs. Legacy Back End:
- India has built a world-class digital front end through India Stack (UPI, Aadhaar, Account Aggregator framework).
- Much of it still runs on fragmented legacy back-end systems, especially in public sector units, State departments, and older public sector banks.
- Indian public sector banks continue to run substantial COBOL and Windows Server 2008/2012 workloads.
No AI Safety Institute:
- India lacks an AI Safety Institute.
- The UK and the US have established world-class institutions to evaluate frontier AI systems.
- India has no dedicated body to test such models against Indian threat scenarios.
- The IndiaAI Mission is focused primarily on development rather than safety evaluation.
Cybersecurity Workforce Gap:
- Estimated at more than 6,00,000 professionals.
- Patch cycles for public sector banks are measured in months, not hours.
- In the Mythos era, attackers can move at machine speed and exploit vulnerabilities within hours.
Recommendations: What India Must Do
- Establish India AI Safety Institute (IAISI):
- Dedicated body to test frontier AI models against Indian threat scenarios.
- Supported by data-sharing arrangements with the UK’s AISI and the US Center for AI Standards and Innovation (CAISI).
- Without such a mechanism, India will remain dependent on foreign assessments of models that have never been tested against Indian systems and vulnerabilities.
- Frontier AI Accountability Framework:
- Modelled on California’s SB 53 and the EU AI Act, but tailored to Indian conditions.
- Any AI company operating in India whose model exceeds defined thresholds (compute, autonomy, or cyber capability) should disclose capability evaluations and known harms to IAISI.
- Could be built into the Digital Personal Data Protection Act (informed consent requires meaningful disclosure of AI risks and capabilities).
- Critical Sector Cybersecurity Upgradation Fund:
- ₹15,000-20,000 crore fund for legacy modernisation in public sector banks and critical infrastructure.
- Fund and co-develop sovereign defensive AI models with domestic deep-tech firms to monitor telemetry, detect anomalies, and isolate compromised network segments in real time.
- Defensive AI Partnership (like AUKUS Pillar 2):
- Pursue a “Defensive AI Quad” with the US, UK, and Japan.
- Secure structured access to Mythos-class capabilities for testing and protecting critical infrastructure.
- India could contribute its threat-modelling expertise and the uniquely varied attack surfaces of its digital public infrastructure stack.
- Diplomatic Leadership at G-20:
- Lead the diplomatic effort to establish that the release of open-weight models above defined capability thresholds (specifically autonomous offensive cyber capability) should be subject to international notification and review requirements.
- India has unique standing: major AI consumer, credible neutral voice between US and Chinese AI policy positions, operator of the largest digital public infrastructure stack in the world.
The Window Is Closing
The Core Problem:
- Not about Mythos versus India, but India’s structural disadvantage in a world where the cost of finding zero-days is collapsing while the cost of patching is not.
- The goal is to prevent a breach at the weakest point from cascading into systemic failure.
Timeframe:
- India has 12 to 24 months to build the architecture needed to stay ahead of the threat rather than chase it.
- Coordination should be driven by the Prime Minister’s Office and not any single Ministry.
The Mythos Era:
- When capabilities of this class become routine, including in unrestrained hands, has already begun.
- What happens if some non-state bad actor takes control of India’s financial systems or examination systems or power plants?
- What about the inevitable proliferation of Mythos-class capabilities from labs that do not share Anthropic’s restraint and from open-weight model releases over which no one has control?
Conclusion
Advanced AI systems are rapidly transforming cybersecurity by identifying vulnerabilities beyond human capability and autonomously combining minor flaws into major attack vectors. While India possesses strong digital public infrastructure, legacy backend systems, workforce shortages, and the absence of a dedicated AI safety framework expose critical risks. India must urgently strengthen AI governance, cyber resilience, and international cooperation to stay ahead of emerging AI-driven threats.
