Cybercrime refers to criminal activities where computers, smartphones, networks or the internet are used as tools, targets, or both. Common examples include phishing emails and messages that trick users into sharing passwords or OTPs, banking and UPI frauds, identity theft, hacking of accounts, spreading malware, and online harassment or stalking. As daily life and financial transactions have moved online, cybercrime has become more frequent and more sophisticated.

Many cybercrimes exploit human psychology rather than high‑level technical weaknesses: scams often create urgency (“your account will be blocked”) or pretend to be official messages from banks or government agencies. Basic precautions can reduce risk dramatically: never sharing OTPs or PINs, checking website addresses carefully, avoiding unverified apps, using strong and unique passwords with two‑factor authentication, and keeping software updated. When a cybercrime occurs, it is important to act quickly—inform your bank or service provider, save evidence like screenshots and messages, and file a complaint with the appropriate authorities. Awareness and digital hygiene are as important as technical security measures.
