After some googling, it seems like someone else may be trying to link my savings account to their own PayPal account. If this is the case, I find it odd that PayPal apparently only made one deposit of zero dollars, don't they usually deposit two small amounts to have you verify your info?
I also have no clue how they would have gotten my bank account information. I have never given this account info to anyone besides employers for direct deposit purposes. It couldn't have been through a phishing scam either because as far as I know I have not clicked any sketchy links or put my bank info in anywhere.
I have contacted PayPal and this is their response:
Hi ! Thank you for patiently waiting. My name is [removed]. Thanks for reaching out to PayPal Messaging Team! We appreciate your time bringing this issue to our attention and I'll be more than happy to assist you with that.
PayPal is recommended by the banks that we use to process our transactions to identify inactive bank accounts that may be linked to PayPal accounts. To do this, we send a prenotification (prenote) in the form of a zero-dollar deposit to all bank accounts on file linked to PayPal accounts.
This prenote does not affect the balance of your bank account and may not show up on your monthly statement, depending on your bank. There is no action needed from you if your bank account is verified as an active account.
If your bank account is inactive, the prenote will be returned to PayPal and we will send you an email to notify you of the inactive bank account being unlinked from your PayPal account. PayPal plans to send these prenotes every 6-12 months to ensure all linked bank accounts are still active.
