It’s an unfortunate reality, but attackers can wreak havoc with your cell phone or PDA by taking advantage of the very features that make your life more convenient.
For example, attackers can spam you with text messages that may result in extra charges or infect your devices with malicious code that allows them to use your service. Attackers who gain control of your service may use your device to attack others.
The U.S. Computer Emergency Readiness Team (www.us-cert.gov) recommends the following steps to protect your portable devices:
Just as you do with your computer, follow the guidelines to secure your cell phone and PDA.
Exercise caution in posting your cell phone number and e-mail addresses because attackers often use software that browses Web sites for this information to use in attacks. Limit your risk of becoming a victim by limiting the number of people who have access to this information.
Avoid using links sent in unsolicited e-mail or text messages because they may direct you to a malicious Web site.
Take advantage of the security features offered on your device.
If you decide to download software from a site that is supposedly secure, look for a Web site certification. Another option is to save the file on your computer and scan it for viruses before opening it.
