A data breach occurs when a hacker gains unauthorized access to a company's servers and steals the user database. This can include emails, passwords (sometimes in plain text), names, addresses, and even financial information. That stolen data is then sold on the dark web, where other cybercriminals use it to break into your accounts.
If your email appears in a breach and you were using the same password across multiple services, an attacker can access all of those accounts. This attack method is called credential stuffing and is responsible for over 80% of personal account hacks. That's why it's critical to use a unique password for every service and store them in a password manager.
