This "older woman, somewhere in her 60s" probably just consumes a lot of news, as is common for people in that age group.

"DNI" isn't exactly a secret acronym for Director of National intelligence; if you enter the acronym into a news search engine you'd see it's commonly used in news articles. Also the website is literally DNI.gov.

I'd agree the North Korea thing is weird, but maybe she was just making conversation and dug herself into a hole. Plenty of Uber drivers have also told me vague stories about times they visited Country X long ago (many of which I thought didn't check out, but smiled and nodded anyway) just to keep the conversation going.

Certainly it is a possibility that the Uber gig could be some sort of cover, but I think it's unlikely.
