Can I drop a pacemaker 0day?
Call up CNN and offer to demonstrate how BIOTRONIC is so evil that they refuse to fix their pacemakers.  Hook it up to an ECG and use your phone to make it flatline.  Then turn to the camera and tell the audience, "because BIOTRONIC doesn't want to pay to fix their product, I can now <i>kill your grandmother</i> just by walking past her on the street."<p>Watch how long it takes them to fix it then, and watch how reactive they become to responsible disclosure next time.<p>Also, short their stock before you go on TV.  A little something for your troubles.
