Insurance companies don't pay attention to anything but money. So unless the hacker threatens to cancel his policy, he'll go unnoticed.
Also, I cannot name any names, but I might know 2 big names that don't even know how to contact their own IT security, because they don't know where they're located! It's just a bunch of "No", "I don't know" and "Sorry" with insurance companies, like cash sucking vacuums let off the wire.
True story, no shit. Back in the Y2K days you could walk around these places randomly. For instance, if there was an attractive woman working in a certain department, you could just plop down next to her and talk. If a manager would come up to you and ask where you're from and what you are doing, you could just say "I'm on the COBOL Y2K thing.". When they told you to get back to your department, you could say "I'm already there" and they would just look at you a little apologetic and say "Sorry." walking away. NOBODY KNEW!
