Compromises in 2013

Total compromises in 2013 were just under 457 million, much larger the 2012 total. 457 million is more than twice the previous high count of 251 million in 2009. At 590 the incidents of compromise are lower than 2012’s 670. The compromises are getting larger.

The single largest financial compromise was 200 million accounts in 10/21/2013 at Court Ventures, now owned by Experian. The single largest non-financial compromise was 110 million accounts on 7/17/2013 by Tumblr. Target exposed 40 million financial and 70 million non-financial accounts in December 2013.

Non-financial compromises expose social security numbers, names, email addresses, telephone numbers, medical information or other personal data, Financial compromises expose charge card or bank account information.

Perhaps even worse than the above were the Femtocell compromises (7/15/2013) and the BlackPOS skimmer that surfaced in March 2013. We may never know the extent of their damage. See for more information on BlackPOS.
