We upgraded our systems some time ago to a system that is not currently vulnerable to this intrusion. To help explain, the Heartbleed bug was introduced in December 2011 in OpenSSL version 1.0.1 and we have not been running the affected versions, thus this has not made us vulnerable to the exploit. We do not have evidence that any Digital-Tutors accounts have been compromised. As a security precaution, we encourage you to change your password on a regular basis.
