<prompt> Human: Mom got a fake call from a caller ID Wells Fargo. When she called the fake back, there was an automated response. So I called the actual WF and they said that the was not associated with them. How did the fake know that my mom banked with WF?  <response>: Social engineering. Sometimes its a total guess on the scammers part. Theyll try to get the victim to reveal account numbers, Social Security numbers, etc. by using tricks saying this is urgent, or your account may have been compromised.Never, ever give that type of information over the phone.
