Nearly 17.5 million smartphones and tablets were activated Christmas Day, the highest number of activations in one day ever.
Unfortunately, it's also means more targets for hackers.
"On every single device where you can get a communication, there's someone who's willing to put a fraudulent message out to lure you in," warns McAfee's Michelle Dennedy.
Particularly vulnerable to "phishing scams" are youngsters on mobile devices.
Dennedy says kids have become the target of choice for hackers, but adults are still falling prey too.
Experts say all of it's insidious, but mobile phishing scams are on the increase because the scammers have become more mobile, too.
