A cautionary slide from #defcon on attribution of hacks.
Lessons that seem lost on media outlets that repeat attributions in headlines but leave equivocation on attributions buried in text.

But a “liar as source” alert at the beginning of an article, would give readers a shot at forming a considered option of a parroted tale from agency sources.
