Scottrade is quick to stress that neither passwords nor trading platforms were at risk, and it's offering a free year's worth of identity protection services if you're still worried about fraud two years after the incident took place. Still, the revelation isn't exactly confidence-inspiring. It suggests that the company's security measures weren't thorough enough to even detect the hacking attempt, let alone stop it, and that millions of customers were unaware of the danger until the feds stepped in.
