Witness to a cyber takedown

South Korea has been on heightened alert after a suspected cyber attack on major media outlets and banks.

But what is it like to experience a computer outage that may in fact be a cyber attack?

I talked to Seoul resident and KBS employee Luke Cleary about the massive computer outage in South Korea.

Cleary was among the first to tweet a screengrab of what the outage looked like.

"First I thought it was just my computer, and slowly we started to realize other people in the office were being affected as well," says Cleary.
