Adobe (oct 4, 2013 – jan 1, 0)

Description:

In October 2013, 153 million Adobe accounts were breached with each containing an internal ID, username, email, <em>encrypted</em> password and a password hint in plain text. The password cryptography was poorly done and <a href="http://stricture-group.com/files/adobe-top100.txt" target="_blank" rel="noopener">many were quickly resolved back to plain text</a>. The unencrypted hints also <a href="http://www.troyhunt.com/2013/11/adobe-credentials-and-serious.html" target="_blank" rel="noopener">disclosed much about the passwords</a> adding further to the risk that hundreds of millions of Adobe customers already faced.
