Home WiFi Network Security Failings Exposed

An anonymous reader writes "The shocking state of home wireless (Wi-Fi) network security in the UK has been revealed by a life assistance company study. CPP used an 'ethical hacker,' Jason Hart, to test thousands of Wi-Fi networks across six UK cities, including London. He found that many didn't even have a password and roughly half of home UK Wi-Fi networks could be hacked in less than 5 seconds."

    My Wi-Fi has no password, and that's a purposeful choice. While evaluating the passwords on WiFi that does have a password is a reasonable analysis, it's not reasonable to call any WiFi without a password as unsecured.

      Frankly, spoofing wireless MAC addresses are easier than cracking WEP. Hell, one of the first steps in using backtrack, etc, is to spoof your mac before associating with the AP.

      On the other hand, simple MAC based filtering is a perfectly effective way of making it clear that the Wifi is not intended for public use. It's not a half bad option if you don't really care much but want to let normal polite people know your intentions.

      It will also keep MOST people looking for free Wifi out.

    Honest question here. Say I wanted to setup and open a WiFi AP for neighbors to check email, etc, when their connection is down.

      Leaving your wireless AP open doesn't make you a common carrier. From Title II of the Communications Act of 1934:

      (h) "Common carrier" or "carrier" means any person engaged as a common carrier for hire, in interstate or foreign communication by wire or radio or in interstate or foreign radio transmission of energy, except where reference is made to common carriers not subject to this Act; but a person engaged in radio broadcasting shall not, insofar as such person is so engaged, be deemed a common carrier.

      Running an AP basically makes you a person engaged in radio broadcasting, and as we see, that is explicitly not covered. Likewise, if you're not carrying traffic for hire and aren't under an FCC license, then you are also not covered.

      But then again, this is Slashdot, where people keep repeating things they heard whether they actually know what they're talking about or not.

      Not in the sense of a W or a K station, but its still broadcasting radio traffic. It still doesn't make you a common carrier due to other restrictions. Most things people think are common carriers aren't and never were. Likewise, "safe harbor" means that if the carrier meets the requirements for compliance with CALEA, that they can't be held liable for not being able to do anymore.

      Either way, the end case is the same. Neither of these constructs have anything AT ALL to do with whether or not you're going to get boned if someone jumps on your AP and starts committing crimes.
