Almost certainly the US Treasury's Specially Designated Nationals list:

Sure enough, searching the list for "Hasan Ali" gives seven hits.

There is no process for getting off the list. Names just ..... appear there. No evidence or other legal case is required. Just a bureaucrat deciding they don't like you.
The US Constitution explicitly forbids blacklisting of individuals via law for this sort of reason (laws of attainder). Unfortunately such laws are rarely struck down because blacklisted individuals are usually foreign, and thus don't have much access to the US legal system or interest in taking things to the Supreme Court. Also the term "law of attainder" or "bill of attainder" usually means a law that explicitly enumerates the people it's meant to effect, such as the Magnitsky Bill. Laws that create blacklists maintained by the executive branch isn't something the framers appear to have anticipated, though their intention is quite obvious.
