IRS Briefly Exposes ‘Tens of Thousands’ of Social Security Numbers on Website

The IRS has exposed “tens of thousands” of Social Security numbers on a government website, according to the public interest group, Public.Resource.org.

The data breach relates to transactions made by nonprofit political groups, according to Atlantic magazine. The organization said it learned of the breach while working on an unrelated audit of an “improperly vetted shipment” of IRS data on DVDs and informed the agency, Fox News reported. The IRS shut down the site the next day. The group said the Social Security numbers were mostly those of donors, though some were also from people who prepared tax returns to furnish to the IRS. Public.Resource.org. founder Carl Malamud told FoxNews.com that roughly 100,000 Social Security numbers were exposed.
