> That would be nice if it worked.

It looks like you didn't even try it. In order to do what the GP described, when your bank calls you, you say nothing and answer nothing. You hang up and call back on a number you know.

> Calling back was also impossible since apparently there was no way to get connecter back to the person with whom I was speaking.

You don't have to. You just ask the bank when you call them back: did someone just call me a little bit ago? What about?

If the bank can't answer that question, it's time to find another bank. Any reputable bank will be able to look at your file and see that a call was made to you and what the issue was.

> The next time they called, they didn't ask for the security questions anymore and just got to the point immediately. They have never asked for it since.

This does not look like success to me. It looks like failure. What your bank should be doing is sending you a message via some known channel--like the message center on their website, where you can see messages for you when you log in--telling you that there is an issue that you need to call them about. If you're giving information to someone who calls you out of the blue and says they're from your bank, you're setting yourself up to be scammed.

I did do exactly that. I asked them for a reference that I could give when I call back. They couldn't give me that. I then did try to call them back, and said "someone called me about something just now, what was it?" and they were not able to tell me.

> If the bank can't answer that question, it's time to find another bank.

Thankfully, that's not my normal bank. This was the bank that has by car loan. That's my only interaction with them. It's unlikely I'll have more business with them.

> This does not look like success to me. It looks like failure.

Absolutely. This along with the other issues suggests that they value convenience over security. Also, this is not a small bank we're talking about.

I have never seen issues this bad with other banks, but the problem is that when there are banks that get away with this, that suggests people in general do not make a fuss about it and simply accepts whatever people tell them on the phone. If nothing else, it proves why phone scams work.

If the bank didn't even have an answer when I asked them to authenticate themselves, that suggests very few people even ask.

> I asked them for a reference

Asked who? The people who called you out of the blue and you weren't sure it was legit? I wasn't recommending that at all. I said, explicitly, that you say nothing and answer nothing when you are the recipient of the call. You only say or ask anything when you are the one who initiated the call, to a number that you already know via some other information channel belongs to the bank.

> I then did try to call them back, and said "someone called me about something just now, what was it?" and they were not able to tell me.

Did they say there was any issue with your account? If there wasn't, then that would indicate that the previous call you got out of the blue was not legit. If they weren't even able to tell you that, then yes, this sounds like a really incompetent bank.

That won't help: all the phisher has to do is make a call at around the same time that the legit employee called you. The person you called back would probably not be able to tell you what the call should be about anyway.

The idea is to call the institution back, often customer service, or log in to your account and check for alerts or messages. If customer support knows nothing about the contact attempt, I presume it's not legitimate.

And I'm saying that even if the customer support knows about the call, that doesn't mean that the next call you get in 2m from the bank is legitimate.

In all cases, anyone reaching out to you from your bank should be treated as not legitimate. The only way to do this is to call the bank yourself, and get put through to the person who wants to talk to you.

Any other way including the way you said you'd do it is vulnerable to phishing.

You don't call the bank, check whether it's legitimate, then wait for them to call you again. You call, confirm that they were attempting to contact you, then complete the issue on that same call.

> Calling back was also impossible since apparently there was no way to get connecter back to the person with whom I was speaking.

I already responded to this in my original post in this subthread.

You're not wrong about the incoming calls, but I can't figure out who you're replying to. Nobody above you in the thread seems to be suggesting that the bank ever call you. And certainly not call again in a short time.

The post I replied suggested that checking with the bank will indicate whether a call was legitimate or not.

I'm saying that checking with the bank doesn't indicate that a call was legitimate, so there's no point in checking with the bank.

> I'm saying that checking with the bank doesn't indicate that a call was legitimate

If you call the bank, using a customer service number that's already known to you, either they will say there's an issue with your account or they won't. So calling them does tell you, indirectly, whether the previous call (that you hung up on and gave no information to) was legitimate or not. But more importantly, it tells you, regardless of the status of the previous call, whether or not there is an issue with your account, and that's what you care about.

Note that you never have the bank call you back in this scenario. You call them, and that's it. You don't call them and ask them to call you back.

> all the phisher has to do is make a call at around the same time that the legit employee called you

How does the phisher have information about what time the bank is calling?

Also, doesn't this mean you're getting two calls? If you get two calls and the bank says they only called you once, that's kind of a red flag too.
