the oil filter is hidden, and it is hard to find, here is a link to a picture i've found online of a 09 malibu engine and a ratchet ontop of the location where the oil filter is take a look, i believe that your malibu might have a plastic cover ontop which you must take off to get to this part of the engine because that plastic cover covers everything good luck, heres the link
