So I got a letter from the NY State Comptroller that someone had fraudulently attempted to collect unclaimed funds in my name. I spoke to the Comptroller's Office who explained the amount was small, only about $100 from a couple of old, closed accounts in my name (I used to live in NYC a few years ago before coming to DC). What alarmed me is that the person who tried to collect the funds used my correct social security number! (although he/she had the wrong address for me hence why the Comptroller's Office suspected fraud and reached out to me). Someone out there having and using my social security number, of course, freaked me out! I checked my 3 credit reports and there is nothing wrong with them as of right now (no new accounts, etc.). Other than this interaction with the Comptroller's Office, I have no information to suspect that my social security number has been used for any other fraudulent purposes. I should add that I was a federal employee for a couple of years so I assume the OPM hack got my info (and I even received one of those letters from OPM saying that my info "may have been compromised" in the hack).
What, if anything, should I do to protect myself going forward! Please help!
