Earlier quoted context omitted.
"I mean, look at this: it was a STATE-sponsored-entity that did that to us! We were overwhelmed... Did not stand a chance... I need a hug..." - At least this is how I interpreted it. They put in all the right words: "threats, Industry, government, crosshairs, strategic". Edit: "...by what it believes is a state..."??? Who is IT?
If they claim it was a state-sponsored attack and then a non-state-sponsored hacking group makes a credible claim to have been the perpetrators, Yahoo will look even worse than they do now. I doubt Yahoo is saying 'state-sponsored' just for PR.
Besides, "they" don't claim anything. "They" cleverly claim that "_it_ believes" it was a state-actor. Who is this _it_ they conveniently hide?
