Most people know what the term “hacker” refers to. But, do you know what “Wardriving” or “Cantenna” mean? Further, most people have embraced some type anti-virus software for their desktop or laptop as a norm like getting the oil changed every 3000 miles on the car or truck but are leaving themselves vulnerable to malicious attacks, theft, and hacks on their Wi-Fi, laptops and smartphones.
Wardriving and Cantenna Defined
Wardriving is the act of searching for Wi-Fi wireless networks by a person in a moving vehicle, using a portable computer, smartphone or personal digital assistant (https://en.wikipedia.org/wiki/Wardriving).
A Cantenna (a portmanteau blending the words can and antenna) is a homemade directional waveguide antenna, made out of an open-ended metal can. The tiny design makes them ideal for mobile applications such as wardriving. (https://en.wikipedia.org/wiki/Cantenna). 
Whether you are using a Wi-Fi connection on your laptop or smartphone in your home, office or favorite public place, you are vulnerable to Wardriving and the reach of a Cantenna (some can reach your signal from miles away).

- Install a security app on your phone. The same people you would go to for anti-virus software for your desktop or laptop (Avast, AVG, Bitdefender, Kaspersky, Lookout, McAfee and Norton) all have apps, most for under $10. See this link; (Tom’s Guide, Tom’s Guide Staff, Best Antivirus Software and Apps 2016, August 5, 2016, https://www.tomsguide.com/us/best-antivirus,review-2588-7.html).

If you are rate shopper or options adventurer Google “wireless cloud options.”
