Revision summary
Cybercrime targets persons, money, computers, and critical infrastructure, often in mixed form. Phishing, UPI fraud, ransomware, CSAM, and CII attacks are the live Indian set. IT Act plus ordinary criminal law, CERT-In, NCIIPC, I4C, and RBI rules are the state toolkit. Backups, MFA, platform duty, and forensic capacity are the practical layer. Most retail cases are social engineering, so literacy is a security control.
Model answer
Introduction
Cybercrime is offence in which a computer or a network is the target, the tool, or the scene of evidence. In India it rides cheap smartphones, UPI, and social media. Types differ; the fight has to mix criminal law, CERT-In, banks, and public habit — not only a new section in the IT Act.
Body
Types
- Against persons: phishing, SIM-swap, OTP fraud, sextortion, cyberstalking, morphing, and child sexual-abuse material online.
- Against property and finance: ransomware, business-email compromise, credit-card and UPI fraud, crypto-enabled laundering, and theft of intellectual property.
- Against the State and infrastructure: website defacement, DDoS, espionage, attacks on CII (power, finance, telecom), and information operations.
- Against computers themselves: malware, botnets, supply-chain compromise.
- Intermediary-enabled harms: fake news for riot, terror recruitment, and drug or arms markets on encrypted apps — crime that is social but cyber-delivered.
Legal and institutional measures
- IT Act, 2000 (with 2008 amendments): unauthorised access, data theft, impersonation, child pornography provisions; IPC/BNS for cheating, defamation, sexual offences that merely use a phone.
- Indian Computer Emergency Response Team (CERT-In) for incident response and directions; NCIIPC for designated critical information infrastructure.
- Police cyber cells, the I4C (Indian Cyber Crime Coordination Centre), and the national cybercrime reporting portal.
- RBI and NPCI rules for payment fraud, two-factor authentication, and bank liability frameworks.
- International: MLATs, Interpol, and cooperation even where India is cautious about the Budapest Convention’s politics.
Technical and social measures
- Hygiene: updates, MFA, segmented networks, backups against ransomware, and no internet-facing SCADA.
- Platform duty: faster takedown of CSAM and fraud pages; KYC on wallets; audit of large intermediaries.
- Literacy: most retail crime is social engineering. School and bank campaigns matter more than a new firewall logo.
- Capacity: trained magistrates and forensic labs so Section 65B evidence actually convicts.
- Supply chain: trusted telecom gear and software bills of materials for government and CII.

Conclusion
Cybercrime ranges from OTP theft to ransomware on a grid. Fighting it needs the IT Act and IPC together, CERT-In and I4C, payment-system rules, and a public that does not type an OTP to a stranger. Technology without investigation and literacy will not close the menace.

-
Is every WhatsApp cheat only an IT Act case?
Often it is IPC cheating plus IT Act sections. Charge-sheets should use both, not a ritual IT Act citation.

Can India arrest a foreign ransomware gang easily?
Attribution and extradition are slow. Resilience and payment-trail disruption matter as much as a wanted poster.

Explain intra-generational and inter-generational issues of equity from the perspective of inclusive growth and sustainable development.
Inclusive Growth
Intra-generational equity is fairness among people alive now; it is the core of inclusive growth. Inter-generational equity is fairness toward the unborn; it is the core of sustainable development. Jobless or unequal booms fail the first test even when GDP rises. Aquifer mining, carbon lock-in, and weak environmental clearance fail the second. Policy must raise present capability without running down the ecological and fiscal stock.
Q2 · UPSC Mains 2020 · GS III · 10 marks
Define potential GDP and explain its determinants. What are the factors that have been inhibiting India from realizing its potential GDP?
Indian Economy
Potential GDP is sustainable full-capacity output, not the latest quarterly print. Determinants are labour, capital stock, TFP, infrastructure, and macro stability. India wastes potential through low female participation, logistics gaps, and factor-market frictions. Bank and corporate stress, weak learning, and informality hold productivity down. Demand shocks open an output gap; scarring can also lower the ceiling itself.
Q3 · UPSC Mains 2020 · GS III · 10 marks
What are the main constraints in transport and marketing of agricultural produce in India?
Indian Economy
Village roads and a thin cold-chain waste perishable produce before it is sold. Small loads and truck dependence keep agri freight costly. APMC concentration, weak assaying, and poor price information squeeze the seller. Distress harvest sales and thin warehouse-receipt credit force low prices. MSP procurement is not a marketing system for most crops and States.
