How to Prevent Phone Hacking

There are two types of phone hacking: hacking into a live conversation or into someone's voicemail, and hacking into data stored on one's smart-phone.

And in today's mobile world, phone hacking is growing as a security issue. As people increasingly store sensitive data on their mobile devices, the opportunity to exploit privacy weaknesses becomes more tempting to unscrupulous frenemies, exes or the occasional stranger.

There is a cottage industry of phone hacking software ostensibly developed for legal uses but is easily abused (password crackers aptly named John the Ripper and Cain and Abel are two examples). Opportunistic hackers can wreak havoc with data deletion or install malicious software that gathers bank account logins and confidential business emails.

So what's a smartphone owner to do?

If you want to be proactive, there are several measures you can take to protect yourself against phone hacking, most of which involve common sense. For example:

Don't leave your phone unattended in a public place.

Be sure to change the default password that comes with a new phone to something more complex (resist the usual "1234," "0000" and 2580)

Avoid using unprotected Bluetooth networks and turn off your Bluetooth service when you aren't using it.

Use a protected app to store pin numbers and credit cards, or better yet, don't store them on the phone at all.

If you're still worried about hacking, there are further steps you can take to protect yourself. However, taking things too far will defeat the purpose of having a smartphone at all.

Avoid accessing important locations such as bank accounts via public Wi-Fi that may not be secure.

Turn off your auto complete feature so critical personal data isn't stored on the phone and must be re-entered every time you need it.

Regularly delete your browsing history, cookies and cache so your virtual footprint is not available for prying eyes.

If you have an iPhone, you can enable Find My iPhone in your settings, and it will locate your phone if you misplace it before the hackers can lay their paws on it.

Use a security app that increases protection. For Android owners, Webroot offers the all-in-one Mobile Security for Android app that provides antivirus protection and allows you to remotely locate, lock up and wipe your phone in the event you lose track of it.
