We're about halfway through season 2 of Mr. Robot, and we're starting to see some major story lines either resolve or get even more complicated. So let's dive right in to the latest episode and review security concepts that came up. This episode was much more plot-heavy than tech-heavy, so this episode review will be shorter than our previous ones. Rather early on in the episode, we see tech-savvy FBI agent Dom very quickly determine that ECorp has just been hacked, likely by Angela. It was a matter of seconds: she saw the ECorp employee panicking over archives suddenly showing as gone or corrupted, and she's ten steps ahead of it.
