Able Lincoln and his green friends
you don't need a big name to make this better, you just need a big budget. Hire a fair to middling CIO who wants to make a name for him/herself and give them a massive budget to hire competent techies and buy best of market security products. Nothing in this hack was clever, it was a failure of these basic systems. In addition if you hire good security people* and pay them well you will increase the mean salary and so attract more good people to the market.
*I mean people who install and manage security, not the box ticking fucktards in security compliance. Need good ones of those too but they are best recruited from technical teams rather than the snake oil stands that seem to be the source of all candidates at the moment.
