A new report from the Identity Theft Resource Center says almost half a billion sensitive personal records were stolen by hackers last year.
Researchers found that close to 447 million records were compromised in 2018, which is a 126 percent increase from the previous year.
While the number of data breach incidents dropped from 2017 to 2018, experts say the fact that more information was exposed indicates a serious issue.
The group's CEO told NBC that it means the way we store our data is making it easier for hackers to collect it.
The report highlights massive data breaches like Marriott International's, which exposed millions of passport numbers, and Facebook's, which allowed hackers to access "tokens" for tens of millions of users.
It also found that 1.6 billion non-sensitive records were compromised last year. That includes information like email addresses, passwords and user names.
In 2018, the business sector had the most breaches, followed by the health care industry.
