I am still not 100% certain about what's going on, but this is the second pay period in a row where my Routing# and Account# have been updated on ADP's website without my consent. Luckily I caught it the first time, and basically just made it out to be a temporary glitch. Now I know something fishy is going on now that it's been the second pay period in a row where my direct deposit info has been updated to the SAME ACCOUNT as last time.
This is the (alleged) hacker's account info where my most recent paycheck was deposited today:
Bank of America
Routing#: 121000358
Account#: 325026596833
