[...] if I am authorized to use a wireless network, and after authenticating myself I use something like wireshark or airopeek to sniff packets, how is this any different than just wardriving open wireless networks w/o authentication? Wardriving generically refers to the activity of identifying accessible access points. The term 'wardriving' is a play on ...

I am not a lawyer, so the following is just from experience: We have found in most countries (exclude the really restrictive ones such as Germany) you should have no ethical or legal issues with wardriving and collecting info on where weak wireless networks are. The problem is more around what you want to do with it - if you haven't been specifically ...

Using this as a source, it appears we can conclude that- (in relation to consumer devices)- Any device purchased in the USA cannot be configured (through normal means) to be operate on channels 12-14, even when changing the locale to EU or JP because it's illegal to provide a device that you can simply configure to break regulations. A device imported ...

Usually within the U.S., special-ordered equipment is required to scan channels not permitted for operation by the FCC. This could be WiFi devices imported from overseas, or specially-licensed equipment manufactured specifically for spectrum analysis. Since consumer electronic devices (including Wi-Fi) sold within the U.S. must conform to FCC Part 15 ...

Analysing kismet XML is the best way to go on this one. There's a script that I've knocked up which should do most of what you're looking for, but feel free to look through it and modify for your purposes. I'm planning to put it in a github repo at some point, but it needs cleaned up a bit before that. That said it should work ok for you at the moment, so ...

FON routers are purchased world wide, and can be set to operate in pretty much any International wifi band. And if you've got a locked firmware on many "standard" devices, you need only load a firmware from a different region. (Especially for USB devices) the hardware is the same, but the firmware itself is soft loaded and can be manipulated with a little ...

Be mindful of how people will interpret '[a] low-cost consultation visit, to help the owner secure their network appropriately.' I offer free pen testing work to open source projects and had one particularly unhinged developer claim (libelously) I was trying to blackmail them. I had even given them the patches and everything they needed to fix the issues, ...

When using open wifi there is no protection of the data at that layer, however if they are using encryption on a higher layer then it's still encrypted. So yes if you listen on open networks you can see any raw traffic over the network. Keep in mind that if the network has a generally known password then it provides no more protection then an open network.

To answer Jeff's updated question. If your network is controlled enough where you are worried about rouge access points, then you would also be using wired security. (802.1x or otherwise.) Besides using a rouge wifi access point, you could be using an undetectable wireless connection on the 700mhz band. It's easier to make sure that everything connected ...

(Sorry for posting on this "more-than-a-year-old" question, came across the topic while searching for somethings similar, hopefully it can help someone) Giskimet stores the imported access points in a SQLite3 database, a suitable format for data mining. While Giskismet ouputs KML graphs, if you have access to the SQLite shell ...

In australia Google is looking like getting into trouble for a breach of privacy. This revolves around the fact that they collected user's wireless router MAC addresses, and stored that information alongside the users residential home address. Whilst this might sound fairly harmless, it appears to be an intrusion of privacy. i.e. the same way that it would ...
