<prompt> Human: Like the title says, my grandma gave out information to a scammer. I looked in the Wiki, but couldnt find anything about scamspost-scam mitigation, or what to do if someone is attacking your identityfinancial security.The only thing my mom has done so far is put a password on the joint account she has with her.What should we do.Also, She says they offered to send her a free phone in the mail. Just typing this makes me wonder how she could be so naive.  <response>: Since the last four digits of SSN is often used to authenticate a customer when calling a bankbrokeragephone company and just about any companies that have your SSN, she should tell them that hers has been compromised, and to set up verbal passwords in addition or in place of the last-four-of-SSN.
