they can't produce an alternate longer chain that's accepted by consensus rules.
all they can do is reorganize recent blocks, the further back they want to go, the more hash power they need to have.
because honest miners are still adding to the honest chain they need enough hash to not only hash the next block but all the blocks theyre trying to reort.
if an Adversary want to do a 10 block reorg I think they need like 80% of the hash to have reasonable chance of success.
the numbers are online somewhere.
