A security breach on Chilean government data at the end of last week ended up alarming people nationwide, after the hacker decided to post the personal data of about 6 million Chileans on the Internet.

The purpose of making the data public was supposedly to make a point, and draw attention on the fact that the country confronts with serious privacy protection issues.

The hacker, who calls himself the Anonymous Coward, first posted the data on a Chilean technology blog, Fayerwayer.com, on Saturday morning, and although the post had been removed by a site editor, they still ended up on other sites, including Google’s Blogger.

Leo Priesto, the administrator of Fayerwayer, reported the post to local authorities as soon as he discovered it. It appears that among the Chilean residents whose data has been exposed is one of President Michelle Bachelet’s two daughters.

Despite the prompt reaction to remove the post, the possibility that some people may have downloaded the data still remains, Prieto warned.

The Anonymous Coward’s posts were accompanied by warnings that personal data in Chile is poorly protected, and information on how to download and access the data.

“If you’re going to extract data from a server, it’s recommended to make a script that doesn’t connect directly to the server, but rather via [anonymous proxies],” the hacker’s post said, according to PC World.

The hacker also mentioned the Chilean President’s daughter: “Bachelet’s daughter has a school pass, although it’s not given to many people because their parents have earnings above a certain threshold.”

The Chilean newspaper El Mercurio was the first to report the breach, and the story has been all over the news for the past days.

However, despite the fact that some people may be concerned about their private data being exposed, the head of the Electoral Service, Juan Garcia, said the information is normally available upon request, and that the database is “intact, secure and protected,” the Associated Press reports.

The data released on the Internet includes names, phones numbers, addresses and identity card numbers of around 6 million Chilean residents. The investigation continues.
