AI and Cyber Threats: How Artificial Intelligence Is Transforming Offensive Cyber Operations Against India

Artificial Intelligence is weaponising cyber operations against India—enabling automated reconnaissance, polymorphic malware, autonomous zero-day discovery, and large-scale deepfake phishing at machine speed, far outpacing traditional defensive frameworks. India ranked second-most cyber-attacked nation globally in 2024 and sixth in 2025, with state-sponsored groups targeting critical national infrastructure including the Kudankulam Nuclear Power Plant and defence establishments during Operation Sindoor.

Quick highlights

  • India ranked 2nd most cyber-attacked nation globally in 2024 and 6th in 2025 (CloudSEK data).
  • Ransomware groups claimed breaches of data linked to Kudankulam Nuclear Power Plant, India's largest nuclear facility.
  • During Operation Sindoor, Pakistan-backed APT36 targeted MoD, Army, Navy, DRDO, NIC, and BOSS Linux.
  • Generative AI reached 1 billion users in 3 years vs. 15 years for the internet—democratising offensive cyber tools.
  • AI enables polymorphic malware that self-mutates in real time, bypassing static antivirus signatures.
  • CERT-In has operationalised AI-driven threat detection, sandbox assessments, and the Certified Security Professional in AI (CSPAI) programme.

Context

A cybersecurity analysis highlighted how AI is transforming offensive cyber operations against India into automated, scalable, and autonomous campaigns. The convergence of Large Language Models (LLMs), machine learning algorithms, and autonomous AI agents across the cyber kill chain has fundamentally shifted offensive cyber warfare from human-speed operations to machine-speed execution, enabling attackers to conduct reconnaissance, generate malware, and exploit vulnerabilities with minimal human intervention.

Key Facts

India's threat ranking: 2nd most cyber-attacked nation (2024), 6th (2025) per CloudSEK. Kudankulam Nuclear Power Plant: Ransomware group World Leaks claimed breach of data and blueprints. Operation Sindoor: Pakistan-backed APT36 targeted Ministry of Defence, Army, Navy, DRDO, National Informatics Centre (NIC), and BOSS Linux. Generative AI: Crossed 1 billion users in 3 years (vs. 15 years for the internet). AI threats: Automated spear-phishing via LLMs, polymorphic malware, autonomous agentic espionage (e.g., Chinese GTG-1002), zero-day discovery (e.g., Claude Mythos model), OT/ICS targeting. India's response: CERT-In AI-driven threat detection; MeitY synthetic content regulation; CSPAI (Certified Security Professional in AI); Pax Silica multilateral partnership.

Significance

AI-driven cyber threats represent an existential risk to India's critical national infrastructure (CNI)—power grids, nuclear facilities, banking systems, and defence networks. The democratisation of offensive AI tools lowers the barrier for both state and non-state actors to launch sophisticated attacks. India's heavy reliance on foreign hardware, proprietary operating systems, and foreign-hosted cloud infrastructure creates structural vulnerabilities that cannot be patched with traditional cybersecurity tools. Developing sovereign AI capabilities is therefore a matter of national security, not merely technological aspiration.

Challenges / Way Forward

Challenges: (1) Underdeveloped sovereign AI stack—India lags in foundational models, advanced GPUs, chip design, and HPC clusters. (2) Foreign technology dependency—imported hardware and foreign-hosted cloud creates structural vulnerabilities. (3) Inadequacy of legacy perimeter defences against self-evolving polymorphic AI malware. (4) Expanding IoT/smart-city attack surfaces. (5) Acute shortage of AI-cybersecurity talent trained in ML threat hunting and automated incident response. Way Forward: Invest in sovereign foundational AI models and domestic semiconductor supply chains; deploy autonomous machine-speed defensive systems (anomaly detection, auto-patching); mandate zero-trust architectures and air-gapping for all CNI (nuclear, defence, banking); enact statutory AI liability frameworks requiring pre-deployment red-team testing; engage strategically through Pax Silica for joint cyber threat intelligence.

The SAVE America Act: US Legislation on Voter Identification and Citizenship Verification

The Safeguard American Voter Eligibility (SAVE America) Act is proposed US legislation that requires documentary proof of citizenship and photo identification for voter registration and voting in federal elections, including mail-in ballots, while enabling states to cross-check electoral rolls with the Department of Homeland Security. Critics argue that stringent documentation requirements risk disenfranchising eligible citizens, particularly those without ready access to passports or birth certificates.

Quick highlights

  • SAVE = Safeguard American Voter Eligibility; proposed US federal legislation on voter registration and identification.
  • Requires passport, birth certificate, or naturalisation documents + government-issued photo ID for new voter registrations.
  • Photo ID mandatory for in-person voting and mail-in ballot submission.
  • States can cross-check electoral rolls with the US Department of Homeland Security to identify potential non-citizens.
  • Election officials who register individuals without prescribed documentation could face up to 5 years' imprisonment.
  • Critics argue the requirements risk disenfranchising eligible citizens lacking ready access to identity documents.

Context

The US President renewed calls for Congress to pass the SAVE America Act, citing concerns over voter identification integrity and non-citizen voting in federal elections. The Act reflects broader political debates in the United States about electoral integrity, documentation requirements, and the balance between preventing voter fraud and protecting universal suffrage.

Key Facts

Full name: Safeguard American Voter Eligibility (SAVE America) Act. Nature: Proposed US legislation for federal elections. Key provisions: (1) Proof of citizenship—passport, birth certificate, or naturalisation documents + government-issued photo ID for new registrations or updates. (2) Photo ID for voting—mandatory at polls and for mail-in ballot submission. (3) Citizenship cross-verification—states authorised to check electoral rolls against US Department of Homeland Security databases. (4) Penalties—election officials registering individuals without prescribed documents face up to 5 years' imprisonment.

Significance

The SAVE America Act reflects a global trend of increasing voter identification requirements as governments seek to strengthen electoral integrity. For India, it offers a comparative lens: India's Election Commission uses the Electoral Photo Identity Card (EPIC) system and allows 12 alternative photo ID documents for voting, without requiring citizenship proof at registration given that citizenship is verified through enrollment in electoral rolls. The debate between electoral integrity and voter inclusion is directly relevant to UPSC themes on democratic governance, electoral reforms, and comparative constitutional frameworks.

Challenges / Way Forward

Proponents argue: Citizenship verification protects electoral legitimacy and prevents non-citizen influence on federal elections. Critics argue: Stringent documentation requirements can act as structural barriers—particularly for low-income, elderly, or minority voters who may not have ready access to passports or birth certificates, effectively disenfranchising eligible citizens. The tension between preventing fraud and protecting universal suffrage is a fundamental democratic governance challenge with no universally agreed solution across democracies.

  • Photo ID mandatory for both in-person voting and mail-in ballots.
  • States can cross-check rolls with US Department of Homeland Security (DHS) for non-citizen identification.
  • Penalty for non-compliant election officials: up to 5 years' imprisonment.
  • Criticism: Risk of disenfranchising eligible voters without ready access to identity documents.
  • India's equivalent: EPIC (Electoral Photo Identity Card); ECI allows 12 alternative photo IDs for voting.

Regenerative Agriculture: Restoring Soil Health and Climate Resilience in Indian Farming

Regenerative agriculture is gaining policy traction in India as declining soil health, water stress, and climate variability threaten long-term agricultural productivity; unlike conventional sustainability approaches, it actively restores and rebuilds ecological health of farmland over time. Key practices include deployment of on-farm bio-inputs (Beejamrut, Jeevamrut, Neemastra, Dashparni), soil cover through mulching and green manuring, multi-tier diversification integrating crops with livestock and agroforestry, and precision micro-irrigation.

Quick highlights

  • Regenerative agriculture actively restores soil fertility and biodiversity, going beyond conventional sustainability (which only maintains existing conditions).
  • Key bio-inputs: Beejamrut (seed treatment), Jeevamrut, GhanJeevamrut (soil microbial inoculants), Neemastra, Dashparni (botanical pest repellents).
  • Practices include mulching, green manuring, cover cropping, minimised tillage, and year-round soil cover.
  • Multi-tier integration: crops + livestock + agroforestry + horticulture + fisheries + apiculture for income diversification.
  • Precision micro-irrigation (drip and sprinkler) maximises water-use efficiency and prevents nutrient leaching.
  • Benefits: enhanced climate resilience, reduced input costs, improved water retention, biodiversity conservation.

Context

Regenerative agriculture is gaining policy attention in India as declining soil health, water stress, and climate variability increasingly threaten long-term agricultural productivity and farmer livelihoods. Unlike conventional sustainability models that aim to maintain existing conditions, regenerative agriculture actively restores ecological health—rebuilding soil fertility, improving water retention, and enhancing biodiversity over time. India's government has been promoting related approaches through schemes like Paramparagat Krishi Vikas Yojana (PKVY) and the Natural Farming initiative under the Bharatiya Prakritik Krishi Paddhati (BPKP).

Key Facts

Definition: Holistic farming approach that restores, rebuilds, and improves ecological health of land over time. Key bio-inputs: Beejamrut (seed treatment with cow dung/urine/lime); Jeevamrut (liquid microbial inoculant); GhanJeevamrut (solid microbial formulation); Neemastra (neem-based pest repellent); Dashparni (10-leaf botanical extract for pest management). Core practices: Mulching (topsoil protection, moisture retention); green manuring; cover cropping; minimised tillage (to protect soil architecture); crop-livestock integration (animal dung and urine as inputs); precision drip/sprinkler irrigation; year-round vegetative soil cover. Multi-tier diversification: Integrates crops with livestock, agroforestry, horticulture, fisheries, and apiculture.

Significance

Regenerative agriculture directly addresses three of India's most critical agricultural challenges: soil degradation, water scarcity, and climate vulnerability. By replacing synthetic fertilisers and chemical pesticides with farm-derived bio-inputs, it reduces input costs for farmers while restoring beneficial soil microbial activity—improving long-term productivity. Better water retention from mulching and cover cropping provides resilience against droughts and erratic rainfall. Multi-tier integration diversifies farm income, reducing dependence on single-crop cycles. It aligns with India's commitments under the Paris Agreement (carbon sequestration through soil organic matter) and Sustainable Development Goals (SDG 2: Zero Hunger; SDG 15: Life on Land).

Challenges / Way Forward

Challenges: Transition from chemical-intensive to regenerative farming requires significant knowledge transfer and short-term yield adjustment. Lack of market premium for regeneratively produced crops discourages adoption. Fragmented landholdings in India make multi-tier agroforestry and precision irrigation systems harder to implement at scale. Policy and certification frameworks for regenerative produce are nascent. Way Forward: Scale training through Krishi Vigyan Kendras (KVKs) and Agriculture Technology Management Agencies (ATMAs); develop market linkages and certification standards for regeneratively produced crops; integrate regenerative practices into mainstream agricultural schemes (PM-KISAN, PKVY, BPKP); encourage Farmer Producer Organisations (FPOs) to aggregate small landholdings for collective implementation.

Australia Confirms First H5N1 Bird Flu Detection in a Mammal

Australia has confirmed its first detection of the H5N1 avian influenza virus in a mammal, marking a significant epidemiological development for the country which had previously reported H5N1 only in birds. The detection raises concerns about potential viral adaptation, zoonotic spillover risks, and the implications for global pandemic preparedness.

Quick highlights

  • Australia confirmed its first detection of H5N1 avian influenza in a mammal—a significant epidemiological milestone.
  • H5N1 is a highly pathogenic avian influenza (HPAI) virus subtype of Influenza A, notorious for its high case fatality rate in humans.
  • Mammalian H5N1 infection raises concerns about viral adaptation—a step toward potential human-to-human transmission.
  • Global H5N1 context: virus has spread widely in wild birds and poultry globally; mammalian cases reported in seals, foxes, bears, and cattle (notably in US dairy herds since 2024).
  • Monitored by WHO, FAO, and WOAH (World Organisation for Animal Health) under a One Health framework.
  • India has reported H5N1 outbreaks in poultry in the past; ICAR and NCDC are the nodal bodies for animal and human surveillance respectively.

Context

Australia confirmed its first detection of H5N1 (Highly Pathogenic Avian Influenza) in a mammal, following prior detections only in birds. This is significant because mammalian infections indicate viral adaptation to non-avian hosts—a prerequisite step for potential human pandemic risk. Australia, geographically isolated and with strict biosecurity protocols, had been largely shielded from global HPAI spread until this development.

Key Facts

Virus: H5N1 — Influenza A, Highly Pathogenic Avian Influenza (HPAI) subtype. Detection: First confirmed H5N1 in a mammal in Australia. Global context: H5N1 detected in mammals globally including seals, foxes, bears, and US dairy cattle (since 2024). Human fatality rate: H5N1 has historically shown a case fatality rate of over 50% in confirmed human cases (WHO data, historical). Monitoring bodies: WHO, FAO, WOAH (World Organisation for Animal Health)—One Health framework. India: Past H5N1 poultry outbreaks; nodal agencies = ICAR (animal health), NCDC (National Centre for Disease Control, human surveillance), DAHD (Dept of Animal Husbandry and Dairying).

Significance

H5N1's detection in a mammal in Australia signals potential viral host adaptation—the process by which the virus evolves to more efficiently infect mammalian cells, a critical step toward elevated pandemic risk. Mammalian infections increase the probability of viral mutations enabling human-to-human transmission. For global health governance, this underscores the importance of the One Health approach—integrating animal, human, and environmental health surveillance—and the need for rapid genomic sequencing and early response capacity. For India, with dense human-poultry interfaces in rural areas, strengthened zoonotic surveillance is essential.

Challenges / Way Forward

Challenges: H5N1 is circulating in wild migratory bird populations globally, making containment extremely difficult. Mammalian adaptations are hard to detect without widespread genomic surveillance. Vaccine development and stockpiling for H5N1 human strains remains inadequate globally. Way Forward: Strengthen One Health surveillance frameworks integrating animal, human, and wildlife health data; accelerate H5N1 candidate vaccine virus (CVV) development and global stockpiling; enhance rapid genomic sequencing capacity at ports of entry; India must strengthen NCDC-ICAR coordination for zoonotic early warning.

  • Manufacturing: Siemens Process (Chemical Vapour Deposition) and Fluidized Bed Reactor (FBR) are the dominant production technologies.
  • Purity grades: Solar-Grade (SoG-Si) = 6N to 9N purity; Electronic/Semiconductor-Grade (EG-Si) = 9N to 11N purity.
  • Applications: Solar PV ingots/wafers (mono-PERC, TOPCon, HJT cells), semiconductor chips (DRAM, NAND, microprocessors), power electronics (EVs, MOSFETs), AMOLED/LCD displays.
  • China dominates global polysilicon production—India's domestic manufacturing deficit creates critical import dependence.

Context

India's Ministry of New and Renewable Energy (MNRE) announced it is formulating a dedicated subsidy scheme to establish 30 GW of domestic polysilicon manufacturing capacity by 2030. This is significant because polysilicon is the most critical upstream raw material in the solar PV value chain—India currently imports virtually all its polysilicon, primarily from China, creating supply chain vulnerability for its ambitious 500 GW renewable energy target.

Key Facts

Definition: Polycrystalline silicon (polysilicon/poly-Si)—a high-purity, hyper-refined crystalline form of silicon with multiple microscopic crystallites separated by grain boundaries. MNRE target: 30 GW domestic polysilicon manufacturing capacity by 2030. Manufacturing process: (1) Smelting quartz/silica sand to metallurgical-grade silicon (MG-Si) at ~1,900°C; (2) Synthesis of volatile Trichlorosilane (TCS) via hydrogen chloride reaction; (3) Fractional distillation to remove impurities; (4) Chemical Vapour Deposition (Siemens Process) or Fluidized Bed Reactor (FBR) to deposit ultra-pure polysilicon. Purity: Solar-Grade (SoG-Si): 6N–9N (99.9999% to 99.9999999%); Electronic/Semiconductor-Grade (EG-Si): 9N–11N (less than 1 ppb impurities). Key processes: Czochralski (Cz) process—melts polysilicon to pull monocrystalline ingots for semiconductor/solar wafers.

Significance

Polysilicon is the foundational upstream input for both solar PV manufacturing and semiconductor fabrication—two of the most strategically critical industries of the 21st century. India's dependence on imported polysilicon (primarily from China) creates a critical vulnerability in its solar energy supply chain and undermines the effectiveness of the PLI (Production Linked Incentive) Scheme for solar modules. Domestic polysilicon manufacturing would complete India's end-to-end solar value chain from quartz mining → polysilicon → ingot/wafer → cell → module, directly supporting the 500 GW renewable energy target and Atmanirbhar Bharat in clean energy.

Challenges / Way Forward

Challenges: Polysilicon production is extremely capital-intensive and energy-intensive, requiring massive continuous power supply and highly specialised closed-loop chemical recycling infrastructure. China controls over 80% of global polysilicon production and can price-compete aggressively. Establishing semiconductor-grade (EG-Si) production requires even more specialised technology, currently concentrated in a handful of global players (Wacker Chemie, Tokuyama, OCI). Way Forward: MNRE's dedicated subsidy scheme should be paired with energy subsidies for polysilicon plants (given high electricity consumption); technology transfer provisions through bilateral agreements; create a domestic demand pull by mandating polysilicon content requirements in India's PLI solar module scheme.
