SEMs are not that expensive. The cheap ones on eBay are $12-14K. The more expensive Chinese ones are closer to $200K.
A security company can easily afford either.
- matthewmacleod 9y agoI don't think the acquisition of a SEM is the barrier to performing this kind of attack. It's still extremely hard
