| Dear Issuu customer, On April 7, the OpenSSL project issued a Security Advisory that detailed a serious vulnerability in the encryption software in use by a large percentage of the internet. This vulnerability (nicknamed "Heartbleed") would potentially allow attackers to retrieve information from encrypted SSL endpoints. For more information on this vulnerability visit http://heartbleed.com. While we do not believe any of our customer accounts have been compromised, we have taken steps to secure Issuu’s infrastructure against this vulnerability by patching our servers and updating our SSL certificates. As an extra precaution we recommend each of our customers take a moment to reset their passwords. We will continue to monitor this situation and secure our service against this vulnerability. If you have any questions, please feel free to contact us any time at support@issuu.com. Sincerely, Christian Sejersen VP, Engineering | | | |
