The Agency for Workforce Innovation (Florida, US) accidentally posted the sensitive information (including Names, social security numbers and employment information) for 250000 people looking for work. All those numbers were left online for at least 19 days. The Washington DC based Liberty Coalition spotted the error.
The Florida Agency for Workforce Innovation made the mistake in October when setting up a computer server. Somehow information that should've been kept private became public, available by an online search. It has since been taken down, but those getting help from the agency aren't happy. The security breach affects people who went to a career service center between 2002 and 2007, even the identities of some their children were posted online.
