QUITO, Ecuador (AP) - Millions of Ecuadorians are at risk of identity theft because a security breach exposed a trove of data including names, phone numbers and birth dates, a cyber security firm said Monday.

Researchers at vpnMentor said the problem stemmed from an unsecured server located in Miami that contained information on over 20 million individuals, most of whom reside in Ecuador. The small South American nation is home to just over 17 million people, meaning nearly everyone could have been exposed.

Ecuadorian President Lenin Moreno said he would push through legislation to ensure stricter data security, while Interior Minister María Paula Romo vowed to hold those responsible accountable.

“The information we’ve received is very serious,” she said.

Experts said Ecuador does not have mechanisms in place requiring companies to protect personal data.

According to vpnMentor, the server in question is owned by Ecuadorian company Novaestrat, which did not respond to requests for comment from The Associated Press.

It wasn’t immediately clear if anyone had wrongfully accessed the data. And while vpnMentor said the breach was closed Wednesday, it also noted the impact can be long lasting.

The information could potentially be used to commit everything from phone scam to business fraud.

“A malicious party with access to the leaked data could possibly gather enough information to gain access to bank accounts and more,” the firm said in a statement.

The data includes national identity card numbers, tax identification numbers and even names of relatives.

The researchers said WikiLeaks founder Julian Assange is among those in the database. The Ecuadorian government granted Assange citizenship during his nearly seven-year stay at the nation’s London embassy. According to the firm, researchers found his name and what is believed to be a national identity number.

The breach is one of several large-scale security lapses exposing the personal data of millions this year.

In July, Capital One said a hacker had accessed the personal information of 106 million credit card holders or credit card applicants in the United States and Canada.
