A Finnish court has ruled that merely operating an open WiFi access point does not make you liable for copyright infringements committed on your network. From the defense attorney's press release:
This alleged copyright infringement had taken place in a specific 12-minute period in July 14 2010, a date when a summer theater play with an audience of around hundred people was held at the premises of the former school owned and resided by the lady.
The applicants were unable to provide any evidence that the connection-owner herself had been involved in the file-sharing. The court thus examined whether the mere act of providing a WiFi connection not protected with a password can be deemed to constitute a copyright-infringing act.
Crucially, the applicants also sought an injunction to prevent the defendant for committing any similar acts in the future. Had the injunction been granted, the legal status of various open WiFi providers would have turned out extremely difficult, as rights-owners would have been provided with a powerful legal weapon to shut them down in cases of similar, arguably insignificant infringements by incidental visitors and customers...
Finally, the court concluded that the WiFi owner cannot be deemed liable for the infringements actually committed by third parties.
Christopher sez, "We just released a 90 second animated video that explains why communities build their own broadband networks, often in competition with big cable. For those who want all the details, we just released a massive 75 page white paper examining 3 community fiber networks in depth - Chattanooga, Tennessee; Lafayette, Louisiana; and Bristol, Virginia that is available here."
Mathias Nitzsche had a nifty idea: using Wi-Fi network names to create a connection between the network's owner and those who spot it in their wireless networks list. His aptly named wifis.org site lets you pick a handle and advertise it through your network name, as in wifis.org/glennocschmidt. This creates an account for you on the site, and makes a Web form available at that address that sends email to your Google or Facebook email, whichever you used to create the registration. The visitor never sees your email address. (Nitzsche avoids having his own registration database, which removes some overhead and security risk associated with retaining passwords.)
I contacted Mathias to ask about privacy and security issues, as one might be concerned about email addresses being stored and the association of a Wi-Fi network name with such. He said (and his FAQ notes) that he doesn't reveal information to third parties. While he's based in Germany, his data and application is hosted in the Google App Engine in the United States.
I'd love to see a variant on this idea, in which an existing network name could be paired with a unique few letter long code that someone would then append to their network. Look up the code, and you'd get the same result. I admit Nitzsche's idea is neater, encoding the URL and the identifier all at once.
The New America Foundation's Open Network Technology Initiative, a US State Department-funded project to build an "Internet in a suitcase" that can be dropped into repressive zones where protesters need network access and the state is trying to take it away. The project -- a very complex piece of technology -- has gotten to the point where it needs a live test, and lucky for the Open Technology engineers, Occupy DC is just down the street, and that's a great testbed.

The idea is that the system will automatically set itself up. Drop a unit near another unit and they’ll start talking to one another and trading data. Add another and all three will talk to one another. Add a thousand and you can cover a whole city. Then if one of those routers is hooked up to an internet connection, everyone on the network can connect. If that connection disappears, users can still try to update an application like Twitter or send e-mail to the larger internet and the outgoing notes will go into a holding pattern until the mesh network finds another connection to the greater net.
That’s harder to pull off in practice, even under ideal conditions — as anyone who’s tried to link even two Wi-Fi access points in their own home could attest. Now throw in the variables that the access points should work in urban and exposed environments, as well as protest zones like Tahir Square. You’ll want to protect dissidents with encryption and deniability.
In Airshark: Detecting Non-WiFi RF Devices using Commodity WiFi Hardware (PDF), researchers from U Wisconsin (Madison) document a firmware for WiFi access points that can detect and dynamically adjust to interference from vacuum cleaners, baby monitors, and other non-WiFi devices that operate in WiFi's radio spectrum. This kind of thing is the backbone of the theory of cognitive radio: devices that can use software defined radio, phased-array antennas, and cleverness to route around other devices in the band, which may, eventually, enable the a lot more data to occupy the radio spectrum. In Airshark's case, the cleverness is in using the wireless cards on the computers and other devices as a sensing array to triangulate on interference.

Airshark taps into the application programming interface of wireless cards used on access points to gather data about radio frequencies in the surrounding environment. The software has been trained to recognize signatures of various devices, and can pick them out from the ambient radio noise with more than 90% accuracy even if signals from multiple such devices are present.
False positives were .39% for environments with four or more interfering devices and using various signal strengths. The researchers found the rate was .068% for signals stronger than -80dBm. "We also found its performance to be comparable to a commercial signal analyzer," according to their research paper "Airshark: Detecting Non-WiFi RF Devices using Commodity WiFi Hardware."
Event-planners, beware -- your attendees will get gouged, reamed, and screwed if you come to TIC.

Caroline Spelman. PHOTO: Reuters/Ueslei Marcelino One would think from reports today that the UK's secretary of state for the environment and rural affairs, MP Caroline Spelman, had lost her bleeding mind. Spelman has been widely quoted about a new report from her agency, Defra, about the threat to infrastructure from global climate change. It covers the extremes of temperature and the routine occurrence of heat above a normal range for the UK, and more storms and severe weather that could ravage Great Britain. The report is an analysis on what changes need be made to keep bridges from buckling in heat or cracking in cold, and nuclear and fossil-fuel plants from suffering damage from previously unthinkable conditions, as well as quotidian issues like floods polluting water supplies and spreading sewage. It's a ripping read, and, please recall, originates from the Tories, the majority conservative part of a coalition government that completely acknowledges the reality of a range of risk potential from climate change. The Conservatives are no Republicans, no matter what else you may say about them. Nonetheless the report's broader issues were overlooked because of a focus on an exceedingly tiny statement buried in it that Spelman highlighted in a speech unveiling the work. Her prepared remarks have her saying:
Our economy is built on effective transport and communications networks and reliable energy and water supplies. But the economy cannot grow if there are repeated power failures, or goods cannot be transported because roads are flooded and railways have buckled, or if intense rainfall or high temperatures disrupt Wi-Fi signals.Read the rest
A Federal judge in Illinois has once again rebuffed a copyright troll's request for easy court orders to allow him to connect IP addresses with people. The judge said that open wireless networks and other factors make the connection between IP addresses and defendants difficult, and that making it easy to connect people and IPs would invite extortionate legal claims.
After the recent raids against people whose open wireless networks had been used by their neighbors to download child pornography, many people advised that this was evidence that leaving your wireless network open would make you potentially liable for the misdeeds of people who happened to use it.
But as this case shows, judges can be savvier than that (and they should be, too). Good law shouldn't punish people for being neighborly.
Baker then went on to cite a recent mistaken child porn raid, where an IP address was turned into a name--but the named person hadn't committed the crime. "The list of IP addresses attached to VPR's complaint suggests, in at least some instances, a similar disconnect between IP subscriber and copyright infringer... The infringer might be the subscriber, someone in the subscriber's household, a visitor with her laptop, a neighbor, or someone parked on the street at any given moment."
The problem that's really killing open WiFi is the idea that an unlocked network is a security and privacy risk.Read the rest
This idea is only partially true. Computer security experts will argue at great length about whether WEP, WPA and WPA2 actually provide security, or just a false sense of security. Both sides are partially correct: none of these protocols will make anyone safe from hacking or malware (WEP is of course trivial to break, and WPA2 is often easy to break in practice), but it's also true that even a broken cryptosystem increases the effort that someone nearby has to go to in order to eavesdrop, and may therefore sometimes prevent eavesdropping.
It doesn't really matter that WiFi encryption is a poor defense against eavesdropping: most computer users only understand the simple message that having encryption is good, so they encrypt their network. The real problem isn't that people are encrypting their WiFi: it's that the encryption prevents them from sharing their WiFi with their friends, neighbours, and strangers wandering past their houses who happen to be lost and in need of a digital map.
On January 27 , Anatel (Brazil's National Telecommunications Agency), the regulatory agency responsible for regulating, executing and supervising the telecommunications sector, seized equipment and fined an internet user R$ 3,000 (approximately $ 1,810 USD) for sharing his wifi connection with neighbors in the city of Teresina, Piauí state (Northeast of Brazil).

Firesheep sniffs unsecured connections with major Web sites over local networks and lets a user with the Firefox plug-in installed sidejack those sessions. A trope has spread that the way to solve this problem is to password protect open Wi-Fi networks, such as those run by AT&T at Starbucks and McDonald's. The technical argument is that on a WPA/WPA2 (Wi-Fi Protected Access) network in which a common shared password is used, the access point nonetheless generates a unique key for each client when it connects. You can't just know the network password and decode all the traffic, as with the broken WEP (Wired Equivalent Privacy) encryption that first shipped with 802.11b back in the late 1990s.
Steve Gibson, a veteran computer-security writer and developer, suggested this the moment Firesheep was announced. A blog post at security consultant Sophos makes the same suggestion. But it won't work for long.
Gibson notes the key problem to this approach in the comments to his post: every user with the shared key can sniff the transaction in which another client is assigned its unique key, and duplicate it. Further, if you join a network with many clients already connected, you can use the aircrack-ng suite to force a deauthentication. That doesn't drop a client off the network; rather, it forces its Wi-Fi drivers to perform a new handshake in which all the details are exposed to derive the key.
Thus, you could defeat Firesheep today by assigning a shared key to a Wi-Fi network until the point at which some clever person simply grafts aircrack-ng into Firesheep to create an automated way to deauth clients, snatch their keys, and then perform the normal sheepshearing operations to grab tokens.

You're safe if your password isn't in any dictionary, including the special dictionaries used for password cracking (these dictionaries will try random words in combination, as well as common letter-number substitutions such as "1" for "i" and so on). The crack works on WPA and WPA2-locked networks.
Your best bet is a long, random string for a password -- 64 bits of random noise will probably foil something like this for a good time to come. But good luck reading the password aloud to your visiting friend when she needs to get her laptop online.

The kits are also cheap. A merchant in a Beijing bazaar sold one for 165 yuan ($24), a price that included setup help from a man at the other end of the sprawling, multistory building.
The main piece of the kits, an adapter with a six-inch antenna that plugs into a USB port, comes with a CD-ROM to install its driver and a separate live CD-ROM that boots up an operating system called BackTrack. In BackTrack, the user can run applications that try to obtain keys for two protocols used to secure Wi-Fi networks, WEP (Wired Equivalent Privacy) and WPA (Wi-Fi Protected Access). After a successful attack by the applications, called Spoonwep and Spoonwpa, a user can restart Windows and use the revealed key to access its Wi-Fi network.
