6 Ways You Invite Hackers to Steal Your Personal Information

Chances are you're not doing enough to protect your personal information from being stolen. "Everyone puts themselves at risk of hackers on a daily basis," says Jerry Irvine, chief information officer of Prescient Solutions and a member of the National Cyber Security Partnership Task Force.

Hackers use viruses and spyware to infiltrate computers and mobile devices to steal data, such as passwords, Social Security numbers and account information. They then can use that information to access your accounts and drain them, run up debt under your name or steal your entire identity.

If you think you aren't at risk of becoming a victim, consider these statistics: Identity theft is so widespread that someone becomes a victim every three seconds, according to a study by Javelin Strategy and Research. Thieves stole more than $21 billion from 12.6 million victims in 2012 by using their personal information. And it can take years for identity theft victims to repair their finances, according to the Privacy Rights Clearinghouse.

Irvine says that few mobile devices have any type of anti-virus solution. And anti-virus solutions for computers only protect against 30% of known viruses. Now you don't even have to click on an image or link on a Web site to inadvertently download a virus. By simply hovering over some links and images with your mouse, you can start a script that will gather info from your hard drive.

Although hackers are quite sophisticated when it comes to gaining access to personal data, Irvine says there are several ways you might be making it easier for them to access your information.

Using weak passwords. If you're using simple passwords for your accounts so you can remember them, you're making it easy for hackers to figure them out, too. Irvine recommends creating passwords with a minimum of ten characters that include numbers, symbols and upper- and lowercase letters. You can test the security of your passwords at Microsoft.com/security. Don't store these passwords in a file on your computer or mobile device that hackers could access by using spyware you might inadvertently install by clicking on links in spam e-mails, texts or Web sites.

Using the same password for more than one account. Plenty of people use a single password for multiple accounts. If a hacker figures it out, suddenly he has access to all of your accounts. Irvine says that, ideally, you should use different passwords for every account. But at least you should use different passwords for your financial accounts than you use for social network accounts.

Using public Wi-Fi. It's tempting to use free public Wi-Fi to get Internet access while you're away from home or work. But these shared networks make it easy for hackers to see everything you're doing. Irvine says. Use your phone's 3G or 4G service to access the Web for a more secure connection, or tether your computer to your phone to use its data plan rather than public Wi-Fi.

Creating user IDs on Web sites. Many retail sites offer customers the opportunity to create password-protected accounts with their billing information to make it easier for them to make purchases online. But Irvine says that you should never create user IDs on Web sites because if thieves hack that site, they'll have access to your credit card and other personal information. Log in as a guest, instead, he says.

Using multiple credit cards to make purchases online. The more credits cards you use, the more chances you give hackers to access your account information and use your entire credit limit, Irvine says. He recommends using a payment service, such as PayPal, to make all of your online purchases. And link only one credit card with a low limit to your PayPal account.

Revealing too much on social networks. When you announce your birthday, your address and even your pet's name on Facebook or other social network, you're giving identity thieves personal information they can use to tap your accounts. So resist the urge to reveal too much online. And when choosing answers to security questions for your accounts, Irvine says you shouldn't use your own information, such as the high school you went to that an ID thief can surmise from your Facebook profile. Use the name of a friend's high school, make up a name for a childhood pet or simply lie about your favorite cereal.
