I'll need to find the talk I lifted it from. Not easy... but looks like downthread a sibling comment gives a relatively decent update about the current speed of compromise.

Answering myself: I think it was a BSides London talk. (Quite likely from 2017.) After doing a search, I don't think it was recorded.

Hence, I can't provide a primary source. Sorry.
