New Delhi, April 25, 2026 — India’s financial sector has been placed on heightened cyber alert after Finance Minister Nirmala Sitharaman described the emerging threat from Claude Mythos as “unprecedented,” calling for a very high degree of vigilance across all banks.
The warning follows a high-level security meeting held on April 23, attended by senior officials including IT Minister Ashwini Vaishnaw, along with representatives from the Reserve Bank of India and CERT-In. The discussions focused on preparing India’s banking ecosystem for next-generation AI-driven cyber threats.
A New Category of Cyber Risk
At the center of concern is Claude Mythos, reportedly developed by Anthropic, which is believed to possess advanced autonomous capabilities in identifying and exploiting software vulnerabilities.
Security assessments suggest that the model can:
- Detect and exploit both known and legacy vulnerabilities at scale
- Chain multiple attack vectors with minimal human intervention
- Accelerate malware evolution and phishing sophistication
- Outperform traditional human-led vulnerability research
The model is reportedly unreleased due to safety concerns, yet recent unauthorized access incidents have raised alarms globally, with regulators evaluating systemic risks to financial stability.

Government Directives to Banks
In response, the government has issued a series of urgent directives to strengthen cyber resilience across the banking sector:
- Real-Time Intelligence Sharing: Banks must establish coordinated threat intelligence mechanisms to detect and share emerging risks instantly.
- Institutional Coordination: The Indian Banks’ Association will lead the creation of a unified response framework for AI-driven threats.
- Cyber Talent Upgrade: Banks are advised to onboard specialized cybersecurity professionals and partner with advanced security firms.
- Mandatory Incident Reporting: Immediate reporting of cyber incidents to CERT-In has been made non-negotiable.
Despite the warning, the Finance Ministry and RBI have maintained that Indian banking systems are currently secure, with ongoing due diligence to further strengthen defences.
CISO Perspective: From Concern to Countermeasure
From a Chief Information Security Officer (CISO) standpoint, the Mythos threat marks a fundamental shift — from human-speed attacks to machine-speed cyber warfare.
The key concern is not just the sophistication of AI, but its scale, speed, and autonomy. Traditional security operations centers (SOCs), designed around human analysis, risk becoming ineffective against AI-driven offensive capabilities.
Defensive Shift: AI vs AI Security Model
CISOs are now advocating a layered, AI-powered defence architecture:
- AI-driven detection and response
Intelligent SOC copilot - Continuous attack surface monitoring
- Risk-based vulnerability prioritisation
- Deception-led security controls
- Deepfake and phishing defence layers
- Supply chain and code security
- AI model and data protection
Expert View
According to Prof. Triveni Singh, the emerging threat landscape demands a decisive shift in mindset and preparedness:
“Following CISOs, the message is unequivocal:
The winners in this new cyber era will not be those with the most tools, but those with the fastest detection, sharpest prioritisation, strongest controls and most disciplined response systems.”
He further emphasized that organizations must move beyond fragmented security approaches and adopt a disciplined, intelligence-driven cyber defence posture aligned with machine-speed threats.
The Real Defence: Operating Discipline
Beyond tools, experts stress a strict cybersecurity operating model:
- 24×7 continuous monitoring
- Zero Trust architecture
- Multi-factor authentication across systems
- Privileged access control
- Exploit-focused patching strategy
- AI-driven red teaming exercises
- Deepfake and phishing simulations
- Tested incident response frameworks
- Regulatory-ready reporting mechanisms
- Board-level cyber risk ownership
Strategic Outlook
India’s proactive stance signals a clear recognition: AI is no longer just a business enabler — it is a national security variable.
The rise of Mythos-like systems indicates that future cyber conflicts will be defined by AI-accelerated offence versus AI-enabled defence.
As global financial systems brace for this new reality, India’s early warning and coordinated response may prove critical in shaping a resilient digital economy.
