What is cyber crime?
Cyber crime is a crime in which a computer, phone or the internet is the tool or the target. The criminal may be far away and may hide behind fake names. Examples: hacking, phishing, cyber bullying, identity theft, ransomware and online fraud.
Hacking
Hacking means getting into a computer, network or account without permission, usually by finding a weak spot.
- Black-hat (unethical) hacker: breaks in to steal data, damage systems or demand money. This is a crime.
- White-hat (ethical) hacker: is hired by the owner to test the system and report weak spots so they can be fixed. This is legal because there is permission.
Protect yourself: update software, use strong passwords, do not use the same password everywhere.
Phishing
Phishing is a trick to steal passwords, OTPs or card details using a fake email, SMS, call or website that looks real. When it comes by phone call it is called vishing; by SMS, smishing.
Clues of a phishing message
- Creates fear or hurry: "account blocked", "pay in 1 hour".
- Offers a prize or cashback you never entered for.
- Link has odd spelling (sbi-l0gin.xyz) or is shortened.
- Asks for OTP, PIN or password. Real banks never do.
What to do: do not click; open the official app or call the official number; report it.
Cyber bullying
Cyber bullying is using the internet to insult, threaten, embarrass or leave out someone again and again. Examples: mean comments, fake profiles, posting private photos, spreading rumours in groups. Trolling (posting to upset people) is a close cousin.
If it happens: do not reply angrily, take screenshots as proof, block and report the account, tell a parent or teacher, and report to the cyber cell if it is serious. Never forward the hurtful post.
Other cyber crimes: identity theft and ransomware
- Identity theft: a criminal uses your name, Aadhaar, photos or bank details to take loans, open accounts or cheat others.
- Ransomware: a malware that locks or encrypts your files and asks for money (ransom) to unlock them. Regular backups are the best cure.
- Cyber stalking and online fraud: following someone online to scare them; fake shopping or job offers.
The Indian IT Act, 2000
The Information Technology Act, 2000 is India's main cyber law. It was amended in 2008 to add more cyber crimes. It also gives legal value to electronic records and digital signatures, which makes e-commerce and e-governance possible.
Important sections
- Section 43: penalty for damaging a computer or taking data without permission.
- Section 66: computer-related offences such as hacking.
- Section 66C: identity theft (misusing passwords or digital signatures).
- Section 66D: cheating by pretending to be someone else online (personation).
- Section 66E: violation of privacy (capturing or sharing private images).
- Section 67: publishing obscene material online.
Cyber appeals go to the appellate tribunal. To complain, use the National Cyber Crime Reporting Portal cybercrime.gov.in or call helpline 1930 (for money fraud, call fast).

Worked examples
1. A student gets an email: 'Your scholarship is approved. Enter your bank password here within 2 hours.' Name the crime and list two clues.
Phishing. Clues: it creates hurry (2 hours) and asks for a bank password, which no real scholarship office asks for.
2. A company hires Meera to break into its website and report the weak points. Is this a crime?
No. It is ethical (white-hat) hacking because the owner gave permission. The same act without permission would be a crime under Section 66 of the IT Act.
3. Someone makes a fake Instagram account in Arjun's name and asks his friends for money. Which crimes and which IT Act sections apply?
Identity theft and cheating by personation. Sections 66C (identity theft) and 66D (cheating by personation).
4. A school computer shows: 'Your files are encrypted. Pay 0.1 Bitcoin to unlock.' What is this and what saves the school?
Ransomware. A recent backup kept offline lets the school restore files without paying. The attack should be reported.
Common mistakes
- Thinking all hacking is illegal. Ethical hacking with the owner's permission is legal and useful.
- Sharing an OTP with a caller who says they are from the bank. Banks never ask for OTP or PIN.
- Replying angrily to a bully or forwarding the hurtful post. Save proof, block, report and tell an adult.
- Writing IT Act 2008 as a new act. The Act is of 2000; it was amended in 2008.
