Just How Risky Are Public Wi-Fi Hotspots?

Ever wonder how safe all your personal information is when it's beamed through the air over Wi-Fi ? If you haven't, then chances are, you haven't taken the right precautions to keep that information safe, either. In clear, easy-to-understand language, the 'Today Show' recently examined the security of Wi-Fi networks. While the video above is a little on the fear-mongering side, it does make some good points about the vulnerability of wireless traffic, in particular, those public hot-spots at your local coffee shop, park, or airport.

Here's what you need to know: Public hot-spots -- most of which are open and don't require a password -- are, by nature, insecure. Sure, they may be easy and convenient to hop on from your computer, but that very openness is also what allows anyone, including hackers, to just walk in and sign on. In other words, when you're signed on to a public Wi-Fi hotspot (or at an unsecured network at your or someone's private home), it's entirely possible for someone to come along and snatch your data, literally out of the air.

Luckily, there are some essential precautions you can take to protect yourself when you're in a public hotspot. First and foremost, get a good firewall program -- not the one built into Windows or Macs, though. Most security suites from Norton, McAfee, and others come with one, and you can download free ones from the likes of Zone Alarm and Comodo. These apps are designed to prevent hackers from gaining access to the data on your PC, and will block and alert you to any attempts to wirelessly access your computer.

Gift Guide: Withings Wi-Fi Body Scale


Withings Wi-Fi Body Scale (Sports Fan, Under $250)

Self-improvement, body-opmtimization technology is coming at us fast and furious, and the Withings Wi-Fi Body Scale is one of the best implementations yet. It's a simple concept: Set up your online profile, and every time you weigh yourself on the scale, your weight and body mass is sent via your Wi-Fi connection to your online account. This means that weight and body fat levels can be tracked over time, which is rather fascinating to see, particularly when you start taking notes on what you're eating on particular days, what you're stressed out about, etc (all of which you can do online). The best part is that it all just works: Setup is super simple, thanks to smart hardware and a user-friendly Web interface. Multiple people can track themselves simultaneously, too; the thing is smart enough to actually know who is standing on the scale each time. So, the Withings Wi-Fi scale may be an ideal gift for the fitness obsessed and/or diet-prone in your life, but at least you'll be able to use it, too (assuming you live in the same place).

How to Fill Up on Starbucks Wi-Fi (Even If You Don't Have an iPhone)


As iPhone users know, you're never too far away from a Starbucks and its sweet, free (to iPhone users) Wi-Fi when you need to get your data on. The rest of us can jump online for virtually free as well. Sign up for a free Starbucks Rewards card, put at least $5 on it, and you'll get 2 hours of free Wi-Fi every day, so long as you use your card for a transaction (from loading up more money to buying a small coffee) at least once every 30 days. If you miss the 30-day window or fall below a $5 balance, you can load up again at the counter and be back online by the time you get back to your seat.

Google Offering Free In-Flight Wi-Fi on Holiday Virgin Flights

Google and Virgin Offer Free In-Flight Wi-Fi for the Holidays
Virgin has been offering in-flight Wi-Fi on all of its flights since May, but prices for the convenience of checking Twitter at 30,000 feet have probably stopped some passengers in their tracks. That is, of course, if they've been able to decipher the convoluted pricing scheme: $12.95 for flights longer than 3 hours; $9.95 for flights under 3 hours; $5.95 for red-eyes; and $7.95 if you want to use a cell phone, media player, or portable gaming device.

Google is giving all passengers on Virgin Airlines a bit of a holiday treat this year by providing free Wi-Fi service from November 10, 2009 through January 15, 2010. You can find out all the details at freeholidaywifi.com.

Google, of course, hopes that you will use this gratis service to check your Gmail, or do some last minute holiday shopping with Google product search. But we know you're just going to use it to tweet about how bad the airline food is. [From: Official Google Blog, Via: Lifehacker]

Tech Tips

Share Your Internet Connection Wirelessly, Without a Router


If you have more than one computer or a Wi-Fi phone at home, but no Wi-Fi router, you can still share your Internet connection wirelessly from the PC that's hooked to your modem. The gist is that the main PC broadcasts its Internet connection over its Wi-Fi card and thus acts like a router itself, allowing other devices to connect. For step-by-step instructions, click here for Windows Vista PCs, here for Windows XP, and here for Macs.

Tech Tips

Unshackle Your Wi-Fi


If your home Wi-Fi network sometimes seems to drag at a snails pace, check if all the PCs on your network have the same speed wireless cards (Wi-Fi or 802.11 comes in three main speeds: in order of slower to faster, b, g and n). It turns out that Wi-Fi routers run only as fast as the slowest device on the network. So even if you have a new "n" router, a new desktop PC with a speedy 802.11n wireless card, and an old laptop with an 802.11b card, the router will only transfer data at the "b" speeds when both are connected at the same time. So if any of your machines are stuck with old 802.11b cards, the only option is to upgrade them with new internal or USB wireless cards, or to make sure to turn off your slower devices when you feel the need for speed.

Southwest Details In-flight Wi-Fi Plans, Yahoo! Partnership


Southwest got official with its Wi-Fi plans late last month, but avid travelers who favor the only airline worth flying anymore (okay, Virgin America and JetBlue aren't bad either) were left wondering about most of the details. Today, the company has fired up a single Row 44-equipped flight, and it has announced plans to equip three more airplanes with in-flight WiFi by early next month. Furthermore, it has nailed down a partnership with Yahoo! in order to offer an in-flight homepage with "destination-relevant content." The service, which has yet to receive final FCC approval, will be tested over the next few months, and if all goes well, we're left to hope, pray and beg that the airline rolls it out fleet-wide. There's no mention of an actual price here, but it would totally rule if it bucked the trend and provided it to everyone for free. Right, everyone? [Via Gadling]

Wi-Fi Hotspots Could Spread Viruses, Experts Say

Digital Wi-Fi Virus Outbreak Modeled
Scientists use computer simulations to model all sorts of things, from the spread of weather patterns to the spread of disease. But a quartet of researchers at the Indiana University School of Informatics are actually using a computer simulation to simulate other computers, attempting to determine how quickly a widespread attack on public Wi-Fi access points would spread across its user base.

Hau Hu, Steven Myers, Vittoria Colizza and Alessandro Vespignani created a model of known public access points in seven metropolitan areas, including downtown Manhattan. They then used known statistics (like, for instance, 40-percent of all Wi-Fi points have no protection at all), and simulated a sequence of events that, in a mere two weeks, would result in 18,000 infected access points in New York City. In this case, "infected" means hackers' gaining access to the Wi-Fi router and modifying it to automatically distribute viruses and steal information in a way similar to that of the Zlob malware we covered last year.

If there's some good news here, it's that the simplest of protection mechanisms on your wireless router can prevent it from being compromised. Don't know where to begin? You can start by clicking here. [From: BBC News]

New Feature Lets You Check Your Gmail Offline


Users of Google's Gmail service can now check their e-mail without an Internet connection, Gmail engineer Andy Palay announced yesterday afternoon via the Offical Gmail Blog.

The feature, which doesn't seem to be showing up in our Gmail Labs yet for some reason, depends upon a program called Gears that downloads and regularly updates a cache of your Gmail messages. So, while your computer is connected to the Internet, it's constantly downloading your Gmail information without your explicit direction. As a result, you will be able to peruse your up-to-date e-mail page in the event you lose a connection.

With the feature, users will be fully able to read, delete, save and send mail -- Google Gears waits for a connection to be established before pushing the offline Gmail commands through. With as much time as we spend on the road, in the air, and generally scrounging for neighbors' Wi-Fi scraps, we can't think of any reason not to give this feature a shot. Aside from it not being available, that is. [From: Official Gmail Blog]

Wi-Fi-Enabled Touchscreen Vending Machines Wash Down the Future




Next up on the list of "things going futuristic"? The soda machine.

Samsung's touchscreen uVending machines are network and Wi-Fi enabled, meaning owners can monitor their stock before the machine runs dry, or even remotely update the information being displayed on its screen. Apparently, it even has an onboard sensor that will send out a warning if it detects physical shock, and a built-in camera to capture potential vandals. Gives new meaning to the expression, "a Coke and a smile!" [From: Techeblog]

Eye-Fi Adds Wi-Fi Uploads to YouTube


If you thought Eye-Fi was a great invention already, then boy, do we have a treat for you. Here at CES, the outfit made famous for pumping out delightfully simple Wi-Fi SD cards for wireless image uploading is taking the next logical step by embracing video. It's currently developing a system that will enable its Wi-Fi SD cards to upload videos directly to YouTube, and if you reckoned the first iteration would be stuck at standard-def, you reckoned wrong. In fact, it's being designed from the ground-up to handle HD uploads from cameras like Nikon's D90, but there's no word yet on how soon the technology will be ready. The big question from us? Will this require an all new card, or can the video functionality be added to existing models? Check the full release after the break.

McDonald's to Offer Free Wi-Fi?

free wi-fi at mcdonald's

As we've often lamented, there simply isn't enough free or open Wi-Fi access in public spaces anymore. It's rare that you'll find a hot-spot that either doesn't require a password or some kind of fee to access it, making the prevalent use of Wi-Fi-enabled laptops, MP3 players, smart phones, and other wireless devices somewhat difficult (we wouldn't care, except that certain gadgets, such as the MacBook Air, actually require the availability of a much-hyped Wi-Fi hotspot to connect, at least without an adapter).

So we were happy when we heard that AT&T just bought public-Wi-Fi provider Wayport, which operates about 20,000 wireless hotspots in airports, hotels (Marriott, Wyndham, Four Seasons) and restaurants (McDonald's). Why? Because, as Mashable points out, many avid laptop users are hoping that AT&T will offer the same deal to McDonald's customers that it offers to Starbucks customers, which is two hours of free Wi-Fi per day to anyone with an AT&T iPhone or BlackBerry, a Starbucks Card, a T-Mobile Wi-Fi-enabled phone or T-Mobile Hotspot account, or AT&T broadband service at home. (McDonald's already offers free wireless access to the Zune Marketplace for Microsoft Zune owners.)

Presumably that means that McDonald's might soon be offering a prepaid buyer's card along the lines of the Starbucks Card (which only needs to be used once a month to keep the free stuff going). Many of the blogs out there seem to think free Wi-Fi at McDonald's is a good thing, but we don't know the last time we wanted to mix our greasy Big-Mac-and-French-Fry-smeared hands and our pristine laptops (not to mention fingerprint-prone iPhone touchscreens).

And honestly, with the price of Quarter Pounders (not to mention Venti Lattes) lately, we're just as keen to pony up the $7.95- $21.95 a month fee for Boingo Wireless, which gives us unlimited access to not only Wayport and Boingo-affiliated wireless hotspots around the world, but also those of T-Mobile and AT&T.

After all, who actually plans to go to McDonald's? Isn't it usually a spontaneous, reckless binge that you fully regret later? And while we're on the subject, would you rather work or surf the Web in McDonald's or Starbucks? Do tell! [From: Mashable and AOL Money & Finance]

Popular 'WPA' Wi-Fi Security System Cracked by Expert

WPA cracked in 15 minutes or less, or your next router's free
They always knew it could be done; that a hacker with enough time and processing power could watch your WPA-protected wireless network and, eventually, decrypt your precious datas. In under 15 minutes, though? "Inconceivable!" those hypothetical security experts would say -- but they're about to get a lesson from Wi-Fi wizard Erik Tews. He'll be giving a presentation next week at the PacSec Conference in Tokyo, describing the "mathematical breakthrough" that, he says, enables him to crack WPA-TKIP -- which, until now, has been considered one of the most secure ways to keep your Wi-Fi network private -- in 12 to 15 minutes.

There are some limitations, as the data sent from a connected device to the compromised Wi-Fi router is apparently still safe, but anything headed the other way is wide open, and could even be supplanted by bogus bits sent from a Cheetos-munching hacker slouching in a rusty Ford Taurus in the parking lot.

Don't believe us? Tews was the guy able to crack WEP in under a minute last year, ironically advising people to switch to WPA ASAP at the time. We can only assume WPA2 is next.

Which Airlines Allow Online Porn?

Not All Airlines to Filter Online Content
We've been eagerly awaiting the arrival of in-flight Wi-Fi here in the U.S., and just when it was starting to get to the point where we could finally expect to get our surfing on at 30,000 feet, a whole new controversy springs up that has everyone wanting to shut the tech off again. The issue is people surfing questionable (a.k.a. porn) content while flying the friendly skies, and different airlines are reacting in different ways.

Right now it breaks down like this: Southwest, American, and Delta will all be relying on content filters to restrict what travelers can access. Meanwhile, Virgin, Air Canada, Alaska Airlines, and US Air will all let surfers go wherever they like -- though some will be asking stewards and stewardesses to keep their eyes open. Who is in the right? We're inclined to say people are making a bigger deal out of this than it really is. There are far more important things to worry about, like prohibitive fees for checked baggage! [From: MSNBC]

Many College Students Prefer Wi-Fi to Beer, Study Claims



The vast majority of college students have been found -- in a recent survey -- to highly value Wi-Fi, according to an article we found on Propeller.com and TechnologyExpert.

Conducted by Wakefield Research, the study found that 90-percent of college students characterize Wi-Fi access as indispensable to their education. Close to 60-percent of them claimed that the availability of free wireless would determine whether or not they would attend a certain school.

While these numbers are slightly surprising, one statistic is truly mind-boggling. According to this survey, a staggering 48-percent of students would sooner give up beer than give up Wi-Fi. Upon reading this figure, we were given no choice but to seriously doubt the integrity of this report; it was, after all, commissioned by an organization called the Wi-Fi Alliance.

But, what if the study is right? Could it possibly be that college students today are more intent on studying than partying? What are the youth of our country coming to?

Our fears were somewhat allayed, though, when we saw that over half of these kids check MySpace and Facebook in class. That, at least, will truly prepare them for the workforce. [From: TechnologyExpert via Propeller.com]
