You don't need a hack for that.
In your control panel on the left side find user groups.
Then find a link that says modify forums or forums premissions (It depends on the version you have.)
For every forum you don't want guests to be able to read find the Guest/Not logged in group and click edit. Simply tell vBulletin you want to assign custom premissions and set can view forum to no. Save and repeat until you have all the forums you don't want guests to view like that.
