Seqrite’s analysis of 8 million endpoints reveals Tamil Nadu recording 7.51 million malware detections from October 2024 to September 2025, ranking seventh among Indian states, with Chennai alone hit by 4.27 million incidents—ninth nationally. Modular loaders disabling defences to deploy ransomware, Nsis.Bitmin cryptojackers hijacking compute and lateral infectors spreading across networked machinery underscore the sector’s exposure in automotive, engineering and fabrication hubs.
For manufacturing CXOs, these telemetry insights signal acute risks beyond data theft: production halts, blueprint compromises and IP extortion, amplified by legacy Windows, USB vectors and IoT expansion without commensurate security. Seqrite notes ransomware peaking at 185 incidents in January 2025, often post-initial footholds, exposing blueprints, schedules and supplier data to dark web markets amid DPDP Act mandates for breach reporting and ₹250 crore penalties.
Attack Surface Explosion in Digitising Factories
OT-IT convergence via IoT sensors, AI quality control and remote vendor tools balloons the attack plane, where single USB infections cascade network-wide and unpatched endpoints enable persistence. Cryptojacking siphons resources silently, while ransomware enforces downtime costing lakhs per hour in high-precision lines.
Strategically, Tamil Nadu’s industrial density demands zero-trust segmentation, endpoint behavioural analytics and OT-specific hardening to protect IP, comply with DPDP’s purpose limitation and lawful processing, and sustain export competitiveness. Seqrite’s DPDP-compliant suite—Threat Intelligence, RRaaS and AntiFraud.AI—offers predictive layers for cognitive threats projected in 2026.
Roadmap for Manufacturing Cyber Resilience
Seqrite advocates enterprise-grade solutions tailored for data-intensive ops: unified telemetry for anomaly hunting, ransomware recovery orchestration and AI fraud detection to preempt cognitive attacks. As factories evolve to edge-cloud hybrids, centralised OT monitoring with remote frameworks will be table stakes.
For risk officers, the report frames manufacturing’s 3.79 million national attacks as a call to action: integrate DPDP readiness, harden supply chains and quantify downtime exposures to justify cybersecurity ROI amid India’s 265.5 million annual threats.
