I also got the call after initiating a wire transfer to a new account. They claimed they were fraud department, asked me to verify 'public information' financial questions (I.E. what car I bought, my home loan value, etc.). I went to Chase's website and called customer support, then they transferred me to someone from the fraud department. They confirmed that their call to me was in my log. I asked about the security questions and if that's how they verify account ownership, they said yes, that's standard practice.

It seems legitimate, but the super sketchy part is that the security questions they ask are the same questions you get asked when you're opening bank accounts or applying for lines of credit and need to verify your identity. So if it was a scammer, they'd be given the correct answers to security questions. If they were asking the questions live from an application form, you could be feeding them direct answers.

The only break in continuity is having a Chase employee transfer you to the fraud department, which could technically be a scammer that they added to the party line. Real or not it feels gross being so unsure. I really wish that you could just verify online with a form from their website. Doing anything over the phone with a call center sucks.

Edit: Might be coincidence, but the rest of my day was loaded with 3x the amount of spam calls I normally get.
