Smaller breaches go unnoticed, but go on nonetheless. And there have been several major data breaches including the COMB breach.

Just recently in June 2021, 700 million LinkedIn accounts were involved in yet another breach. Similarly, 1.1 billion Alibaba accounts were compromised in November 2019. In 2016, Yahoo admitted that 3 billion Yahoo accounts were involved in a breach that dated back to August 2013. Hackers steal and sell or use personal data for nefarious activities that can negatively impact their victims. If you reuse passwords across accounts, a data breach on one site can endanger all your other accounts that share the same password or login credentials. This is often the handiwork of hackers and cybercriminals.

Essentially, a data breach leaks sensitive user data such as email addresses and passwords.
