The Tamil Nadu Cyber Crime Wing, operating under the Tamil Nadu Police Department, issues regular advisories to alert citizens and organizations about prevalent cyber threats, phishing campaigns, digital payment fraud, and ransomware attacks. These advisories provide specific guidance on prevention measures, incident reporting procedures through the national cybercrime.gov.in portal, and enforcement actions taken against cyber criminals. The Wing also coordinates with CERT-In and collaborates with private sector entities to disseminate timely threat intelligence. These advisories complement the Information Technology Act, 2000 and Indian Penal Code provisions applicable to cyber crimes, while addressing state-specific threat patterns observed in Tamil Nadu.

• Provides localized threat intelligence specific to Tamil Nadu's digital ecosystem, including Tamil-language phishing attempts and region-specific scam patterns targeting local businesses and citizens
• Establishes direct reporting channels through dedicated helpline (1930) and district-level cyber crime cells, enabling faster response for victims of online fraud, data breaches, and digital harassment
• Conducts regular awareness programs in collaboration with educational institutions, banks, and IT companies across Chennai, Coimbatore, and Madurai to build cyber hygiene capabilities
• Facilitates coordination between state police, banks, telecom providers, and payment gateways for freezing fraudulent transactions and recovering stolen funds in digital fraud cases
• Issues preemptive warnings during festive seasons and major events about surge in cyber crimes, helping organizations strengthen preventive controls proactively

• Limited technical capacity in tier-2 and tier-3 cities of Tamil Nadu to investigate sophisticated cyber crimes involving cryptocurrency, dark web transactions, or advanced persistent threats
• Delayed coordination between advisory issuance and actual enforcement action, with many advisories remaining informational without follow-up compliance verification for corporate entities
• Insufficient integration with sector-specific regulators like RBI, SEBI, and IRDAI for financial sector cyber crime advisories, leading to fragmented guidance for banks and NBFCs operating in Tamil Nadu
• Lack of mandatory reporting obligations for private organizations experiencing data breaches or cyber incidents, resulting in underreporting and incomplete threat landscape visibility
• Advisories often generic in nature without sector-specific technical indicators of compromise (IOCs) or actionable intelligence that IT security teams can operationalize

• In October 2023, Tamil Nadu Cyber Crime Wing issued urgent advisory after detecting coordinated phishing campaign targeting Chennai-based IT employees using fake job offers from reputed companies, resulting in theft of ₹12 crore through credential compromise and unauthorized fund transfers.
• Following 2022 advisory on digital arrest scams, Coimbatore cyber crime police arrested gang impersonating CBI and customs officials through video calls, recovering ₹2.3 crore extorted from 47 victims including senior citizens and professionals across Tamil Nadu within three months.
• In response to 2023 advisory on fake investment apps, Tamil Nadu police coordinated with Google and Apple to remove 23 fraudulent trading applications that had collectively defrauded over 1,200 Tamil Nadu residents of ₹45 crore through Ponzi schemes disguised as stock market investments.

• Establish mandatory cyber incident reporting framework for organizations operating in Tamil Nadu with prescribed timelines and formats, similar to CERT-In directions, with penalties for non-compliance
• Create sector-specific advisory mechanism for banking, healthcare, education, and manufacturing sectors with technical threat intelligence feeds, IOCs, and recommended mitigation measures aligned to industry standards
• Develop public dashboard tracking cyber crime statistics, advisory compliance rates, fund recovery metrics, and case resolution timelines to enhance transparency and accountability of the Wing's operations
• Strengthen technical forensics capabilities by partnering with IIT Madras, Anna University, and private cybersecurity firms for advanced threat analysis, malware reverse engineering, and blockchain investigation support
