@Webdesinz - this only pertains to your account on ithemes.com - assuming you have one. If not then there's no need to worry, if so then you'll want to change your password there.

Also worth pointing out, if you do have an ithemes account and you use the same password for your wp login, (or anywhere else on the web, to be honest) you'll definitely want to change that as well.
