  1. What is Heartbleed? Heartbleed is a vulnerability in OpenSSL software. OpenSSL is encryption software that accesses websites through a “secure” connection, HTTPS://.

  2. How does it work? To communicate, a client computer and the server send back and forth a short block of data. The block contains a value for the length of the block. The malformed block says its length is 64KB, the maximum possible. The server copies that much data from memory into the response. It may send passwords, encryption keys, etc.

  3. When happened when? OpenSSL release d March 2012 Publicly reported as vulnerable 1 April 2014 Patch released 21 March 2014 (Some fixes had already been put in place then) First proven attempted exploit 8 April 2014 Intentional vulnerability test 12 April 2014
