well as their internet accounts.
"It's like a network cable runs out to the street and invite everyone to plug in," said Jim Whitesell of HomeNetworkDefenders.com, a security adviser to Denton, Texas area.
The culprit is the new wireless network Wi-Fi technology, which allows users to all computers in the House everywhere without wiring connection. Wireless networks are cheap and easy to Setup, but are not secure unless additional steps are taken, according to Whitesell.
Wireless networks are large and have become very popular. "But people do not realize that the signal usually goes well beyond their own walls, and anyone with a portable computer and a wireless access card can probably connect to their network as simple as the owner." said Whitesell. "Anyone can borrow your internet connection to upload illegal websites, sending spam or viruses, and it's all traceable to the owner of the network. Hackers also be able to gain access to the data stored on your hard disk, including passwords, banking information, credit card numbers, etc. "
Whitesell demonstrated how often these wireless networks. Armed with a regular laptop computer and specialized software connected to a GPS receiver, he drove along various streets and random Denton found 130 wireless networks in about an hour. Of these 67% had no security at all. "Wireless networks are incredibly easy to set up. Simply take them out of the box, and then close them. Most people dont realize how vulnerable their computers as soon as their wireless networks work. " Whitesell added.
People really are trying to break through wireless networks absolutely. Late last year, two Michigan men repeatedly cracked the Lowe's home improvement chain's national computer system, get access to credit card and other information, says the Federal Government. How did they do that at the meeting in the parking lot with a notebook computer, they were able to access through Lowes Lowes computer system wireless network.
