In 2026, data breaches are unfortunately common. When a company's database is hacked, user emails, passwords, and personal details often end up for sale on the dark web or leaked publicly.
What happens during a breach?
Cybercriminals use automated tools to test leaked email/password combinations across thousands of other sites in what's known as "credential stuffing" attacks.
How to protect yourself
The most important step is to never reuse passwords across different services. If one site is breached, your other accounts will remain safe.
