More mobile devices means more targets for hackers

Our love affair with mobile devices grew tremendously this past holiday, but with it come some old headaches, and potential danger.

Nearly 17.5 million smartphones and tablets were activated Christmas Day. It was the highest number of activations ever reported in one day, and that 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," says Michelle Dennedy, Chief Privacy Officer at McAfee Internet Security.

They lure you in through the old technique of phishing, and youngsters on mobile devices are particularly vulnerable.

"So, they'll get a link that's sent to them via text and it'll say 'This is a great new offer, click here" and then they'll be infected by malware," says Dennedy.

Dennedy says kids have become the target of choice for hackers, but adults are still falling prey too, like at work through what's called "spearphishing" where someone posing as your boss and emails you.

"It'll say something like 'Urgent, I need you in my office now ! Take a look at this spreadsheet' And as an employee who likes to continue to be employed, you're gonna want to click on that," says Dennedy.

When you do click, you give access to your company's it unit.

Experts say all of its insidious, but mobile phishing scams are on the increase because the scammers have become more mobile, too.
