Why are you considering your parents as some sort of special case? Your question is equally appropriate regarding anyone of any age.

In any case, I would advise everyone (including your parents) to have a safe word/phrase such that everyone knows that if that word or phrase is not used in a important communication, then it isn't really from them.

Beyond that, the usual safety rules apply: never click on links, never talk to businesses if they call you (look up their number and call them back if it seems important), etc.

So, my reasoning is little stupid but it goes like this. I am in my 30s. Let's say if I lose all my money in a scam also - I have time to earn it back and still make it back. Whereas our elders (parents are 60+) who have savings and rely on their savings and can't really earn now - and also have lot of medical bills to pay with their age ==== for them it's like one-shot ending right? That's why I considered them as special case.

That's not stupid reasoning, and I don't know you or your parents. But in the short snippet you wrote, I was interpreting your question as being based on the supposition that your parents are somehow too naive or inexperienced to understand and protect themselves. That's the part that I question.

Particularly since the answer to your question is no different than if you asked the question about anybody of any age.

I guess I need to tell them to not even send any personal detail / bank detail to anyone including me. I sort of felt like may be there is a better solution than just trusting them to follow this. Like we have insurance for death kind of scenarios and medical insurance.. some sort of systematic protection would have been better.
