USA Power Grid compromised?

[JoeSox <joesox () gmail com>]

Am I the only Network Admin wondering how this can happen and why its still
an issue if it was discovered in 2011?
Now I never worked in the Energy field so I am in the dark (pun intended I
guess) on how serious the Public utilities address these issues.
They should have redundant systems so they can clean (reimage, etc)
whatever is there and be done with it??
