Millions of Mexican voter records leaked to Amazon’s cloud, says infosec expert


April 25, 2016

A leaked database containing the voting records of millions of Mexican voters has been discovered by a security researcher.

Chris Vickery, who works for MacKeeper, said he first spotted the Mexican voters’ roll—containing the records of 87 million voters in Mexico—on April 14. Vickery told Ars that he found the database with Shodan, a search engine that can find pretty much anything connected to the Internet.

“The search term that returned this database was just ‘port:27017’ (the default MongoDB port),” Vickery said. “There really was nothing special about the search terms. It was just a stroke of luck that I saw it and followed up.”

He added that the database was not accessible over HTTP: “You had to use a MongoDB client, but all you needed was the IP address. There was nothing protecting it at all.”
