Security researcher Dan Kaminsky and former hacker Kevin Mitnick were targeted because of their high profiles, and because the intruders consider the two notables to be posers who hype themselves and do little to increase security. Mitnick and Kaminsky were targeted for using insecure blogging and hosting services to publish their sites, that allowed the hackers to gain easy access to their data. The files taken from Kaminskys server included private e-mails between security researchers, highly personal chat logs, and a list of files he has purportedly downloaded that pertain to dating and other topics.”]
