- 29. Heartbleed In 2011, one of the RFC's authors, Robin Seggelmann, then a Ph.D. student at the University of Duisburg-Essen, implemented the Heartbeat Extension for OpenSSL. Following Seggelmann's request to put the result of his work into OpenSSL,[19][20][21] his change was reviewed by Stephen N. Henson, one of OpenSSL's four core developers. Henson apparently failed to notice a bug in Seggelmann's implementation,[22] and introduced the flawed code into OpenSSL's source code repository on December 31, 2011. The vulnerable code was adopted into widespread use with the release of OpenSSL version 1.0.1 on March 14, 2012. Heartbeat support was enabled by default, causing affected versions to be vulnerable by default.[23][24][25]
