Digital technologies have reshaped almost every corner of daily life, and this chapter examines both sides of that transformation — the enormous convenience they bring, and the risks and responsibilit…

Every action we perform online — searching for information, buying a ticket, replying to an email, checking a live score — leaves a trace.

Phishing is an unlawful activity in which fake websites or emails that look original or authentic are presented to a user in order to fraudulently collect sensitive and personal details — particularly…

Ransomware is a kind of cyber crime built around digital hostage-taking: the attacker gains access to a computer and then blocks the user from accessing it — usually by encrypting the user's data.
