Personal details of nearly 200 million US citizens exposed

Sensitive personal details relating to almost 200 million US citizens have been accidentally exposed by a marketing firm contracted by the Republican National Committee.

The 1.1 terabytes of data includes birthdates, home addresses, telephone numbers and political views of nearly 62% of the entire US population.

The data was available on a publicly accessible Amazon cloud server.

Anyone could access the data as long as they had a link to it.

Political biases exposed

The huge cache of data was discovered last week by Chris Vickery, a cyber-risk analyst with security firm UpGuard. The information seems to have been collected from a wide range of sources - from posts on controversial banned threads on the social network Reddit, to committees that raised funds for the Republican Party.
