In the ever-expanding digital world, your password is more than just a string of characters—it’s the front door to your online life. Every email, social media post, financial transaction, and cloud-stored file is protected (or not) by the strength of your passwords. Yet despite their vital role, most people still treat passwords as a nuisance rather than the keystones of personal security.

This book is your guided tour through the digital underworld. In ten clear, accessible chapters, we explore the most common and dangerous forms of cybercrime. From phishing emails that trick the unwary into giving up passwords, to ransomware that can shut down entire hospitals or school systems, each chapter lifts the veil on a different threat. We explain how the attack works, who tends to be behind it, what kind of damage it causes, and how to protect yourself and your organization.
