Quantum-Drain Malware: CERT-In’s Warning and the Shift to Post-Quantum Cryptography

In response, CERT-In has directed banks and financial institutions to accelerate the adoption of Post-Quantum Cryptography (PQC). PQC refers to cryptographic algorithms that are thought to be secure against an attack by a quantum computer. This shift requires a complete overhaul of existing digital signatures and key exchange mechanisms. From a policy perspective, this highlights the importance of the National Quantum Mission (NQM) and the need for "Quantum-Safe" standards. It also underscores the role of CERT-In as a proactive regulator in the face of evolving technological warfare. For India to maintain its digital sovereignty, the transition to PQC must be treated as a critical infrastructure priority rather than a mere IT upgrade. UPSC Relevance: This development is a prime example of the intersection between emerging technology and internal security, relevant for GS Paper III. It can be used to illustrate the evolving nature of cyber threats and the importance of statutory bodies like CERT-In in safeguarding national critical infrastructure. Furthermore, it provides a practical context for discussing the National Quantum Mission and the challenges of digital governance in the 21st century.
