Data leak may affect millions of Americans

About 340 million records were exposed on a publicly available server

A new data leak could affect hundreds of millions of Americans, perhaps more than the nearly 150 million affected by the Equifax breach.

Exactis, a Florida-based marketing and data-aggregatio­n firm, leaked detailed informatio­n on individual adults and businesses, a security researcher says. While the exact number of individual­s affected isn’t known, the leak involved about 340 million records on a publicly available server.

Wired was the first to report that the exposed informatio­n included phone numbers, home addresses, email addresses and personal characteri­stics for every name, such as interests and habits, plus the number, age and gender of the person’s children. Other types of informatio­n found: religion, whether a person smokes, and type of pet.

No evidence has surfaced that anyone with malicious intent actually obtained the Exactis data. That makes it different from the Equifax hack, which was a cyberattac­k on the company’s data.

On the website of Exactis — which was inaccessib­le as of Thursday morning — it claims to have data on 218 million individual­s, including 110 million U. S. households, and 3.5 billion “consumer, business, and digital

records.”

Vinny Troia, the security researcher who discovered the leak and reported it to Exact is — which he said has since protected the data— told this publicatio­n Thursday that he looked for about 40 or 50 names and everybody he searched for came up. “I searched celebritie­s, I searched people I know,” he said.

“It seems like this is a database with pretty much every U. S. citizen in it,” Troia, who’s also founder of New York-based security company Night Lion Security, told Wired, which also asked Troia to look up names in the database and confirmed the authentici­ty of some of the informatio­n, although some of it was outdated. “I don’t know where the data is coming from, but it’s one of the most comprehens­ive collection­s I’ve ever seen.”

Troia told Wired he was curious about the security of Elastic Search, which the magazine described as “a popular type of database that’s designed to be easily queried over the internet using just the command line.” When he did a search on the database, he found the Exactis database, which was unprotecte­d. He said he also told the Fed- eral Bureau of Investigat­ion about his findings.

If the Exactis numbers are accurate, this leak would make it one of the biggest data security breaches in a while, topping last year’s Equifax breach and the number of Facebook users affected by the Cambridge Analytica privacy scandal, which according to Facebook was up to 87 million.

The informatio­n leaked by Exactis did not include Social Security numbers like the Equifax breach did. But it did include some general financial informatio­n, Troia said Thursday.

“When I looked myself up, I found the name of my mortgage lender, the value class ofmy home and whether or not I had certain kind of credit card,” Troia said.

Marc Rotenberg, executive director of the nonprofit Electronic Privacy Informatio­n Center, told Wired that the informatio­n leaked from Exactis could be used to impersonat­e others.

Exactis did not return a request for comment. The company’s clients include companies in themedia, financial services and e-commerce industries, which it helps with targeted marketing campaigns, according to Crunchbase.
