Kidnapping ransom scam
You get a call, and a female actress says "Dad, help me!" and the dad might say his daughters name ("Is that you, Mary?") and then they have the daughter's name.
Or they might get the name and some other info from social media.
They're probably not using this yet, because it's not tech that's so easily available, but be aware that DeepFake calls/videos can do this sort of thing, too. This is especially a risk if you or your loved one posts a lot of videos with them talking on social media. Henry from Techlore noted that this could even just become an automated thing one day after a data breach of phone numbers.
