Use strong unique passwords. Do not share OTP. Think before posting photos. Do not click unknown links or .exe attachments. Tell a teacher about bullying or threats. Lock the screen in the lab. Prefer HTTPS and official sites for school work.
Phishing is a fake message or site that steals passwords, OTP or money. Spot urgent language, poor spelling, odd sender IDs and look-alike URLs. Do not click; open the official site by typing it. Report to a teacher or parent.
Do not reply with more abuse. Take screenshots, block the user, and tell a parent or teacher the same day. Schools can act; cyber cells exist for serious threats. You are not at fault for reporting.
It is the record of posts, comments, photos and site data you leave. Colleges and others may see old posts. Mean jokes and personal addresses are hard to erase. Post as if a teacher could read it.
Risks: snooping of passwords, fake login pages. Precautions: avoid net banking, use HTTPS, prefer school/home network, forget the network after use. Do not turn off the firewall to ‘go faster’.
