All my grandparents save one have passed on, and I have no actual relationship with the one that still lives. So I’m not terribly concerned about her, beyond how much I care for any other random senior citizen.

To answer the spirit of the question, though we can talk about my parents, who are grandparents now.

Both are educated and about as tech proficient as I am. However, my mom nearly got caught in a gift card scam a few years ago, where someone was posing as one of her friends. She had even bought the cards, but insisted on going to give them in-person, which exposed the scam.

Because of that, I think my parents are actually pretty safe, as they are now extra vigilant about the messages they receive, and know to follow up anything suspicious using an alternate communication method.

I know, “once bitten twice shy,” isn’t the best defence, but alternate communication methods are. Stress to your loved ones that if they ever recieve a message from someone asking for money, to follow up using a different medium.
