Security giant McAfee warns of the "twelve scams of Christmas" -- a list of the most dangerous scams this holiday season.

Topping the list is the iPad offer scam. Apple products are always a top seller around the holidays and scammers are busy distributing bogus offers for free iPads, according to McAfee.

Hotel and airport wi-fi are also common scams. During the holidays, travelers use free wi-fi in places like hotels and airports, a ripe time for thieves to hack into networks hoping to find opportunities for theft.
