This color-changing polymer warns of tiny damage you can't see
Tiny cracks can actually be a big deal when they're forming inside parts of your car or, say, a metal shell that's flying into space. University of Illinois research, led by Professors Nancy Sottos and Scott White, has lead to a polymer coating that could be an important early warning system, making it easier to find trouble spots before something really bad happens. When cracks form in the polymer, micro-beads also crack open, causing a chemical reaction that visibly highlights the damage with color. The capsules are pH sensitive, meaning any damage will cause a strong color change, from yellow to red, with no additional chemicals needed. Deeper, more serious, scratches and damage will create stronger hues of red as more capsules break open.
Blizzard bans 320,000 WarCraft III and Diablo II players
Blizzard appears to be cleaning house in preparation for its StarCraft II release as well as its Battle.net revamp. In a recent announcement on the service's forums, Blizzard rep Bashiok revealed that over 300,000 accounts were punished for violations of the terms of service for Warcraft III and Diablo II for using hacks and illegal third-party tools (which are essentially hacks). For those of you who have had past experience with Battle.net, these numbers probably don't surprise you. The network has had a long reputation of being fairly easy on people using hacks as Blizzard tends to save up over a long period of time in order to do a massive batch of bans at once. This means that those who are using hacks have a long period of time to abuse the system before anything is done about it. The hacks for some games were rampant enough that other players began using hacks that detect other hacks. Regardless of the reason behind using a hack, it is still against the terms of service and means if you get caught, you're out.
1024-bit RSA encryption cracked by carefully starving CPU of electricity
Since 1977, RSA public-key encryption has protected privacy and verified authenticity when using computers, gadgets and web browsers around the globe, with only the most brutish of brute force efforts (and 1,500 years of processing time) felling its 768-bit variety earlier this year. Now, three eggheads (or Wolverines, as it were) at the University of Michigan claim they can break it simply by tweaking a device's power supply. By fluctuating the voltage to the CPU such that it generated a single hardware error per clock cycle, they found that they could cause the server to flip single bits of the private key at a time, allowing them to slowly piece together the password. With a small cluster of 81 Pentium 4 chips and 104 hours of processing time, they were able to successfully hack 1024-bit encryption in OpenSSL on a SPARC-based system, without damaging the computer, leaving a single trace or ending human life as we know it. That's why they're presenting a paper at the Design, Automation and Test conference this week in Europe, and that's why -- until RSA hopefully fixes the flaw -- you should keep a close eye on your server room's power supply.
WPA networks cracked in just under a minute, researchers claim
To think it was just a few months ago that we thought taking 15 minutes to crack WPA encryption was a feat. Researchers from Kobe University in Japan are claiming they can best that by a wide margin by cracking any WPA-protected connection using the TKIP algorithm within just one minute flat. The details will be revealed at a tech conference on September 25th. Feeling paranoid? Bump up your encryption to the still-secure AES algorithm or WPA2... and if you're just wanting to live life on the edge, consider downgrading to WEP -- it's as good as open at this point anyway.
Palm quietly improving Pre build quality, tweaking hardware
It's not the most comprehensive survey, nor is there any official confirmation, but the crew at PreThinking has checked in with a number of new Pre owners and discovered that Palm's apparently building its webOS handset better lately -- and what's more, it's even made some minor improvements. The biggest change appears to be a fix for that nasty bug that caused the Pre to reset or turn off when the keyboard was closed -- that bit of grey foam pictured was added to the battery compartment to tighten up the battery connection. There's a also word that the screen cracking and unintended rotation issues have been addressed, although time will tell on those, and the button color has changed from pearl to silver. As for improvements, well, there's a new battery model, and the Palm logo is now embossed on the carrying case. Yep, just little stuff, but it's good to see Palm addressing the build issues on the Pre, which are by far the most common complaint about the device. Let us know if you've spotted anything else, would you?
Sony Ericsson's XPERIA X1 developing cracks?
Sheesh, what's up with top tier handsets cracking this year? First the iPhone 3G, now SE's XPERIA X1? A curiously high amount of cracking complaints are starting to build around the web, possibly indicating that a quality issue could be somewhat widespread. We're hesitant to believe that this here quirk is even close to happening everywhere, but it is somewhat suspicious that HTC and SE have recently been rumored to be going their separate ways after this phone has faded from the limelight. At any rate, we've no choice but to poll our own audience here, so have you seen unwanted cracks appear in your X1? If so, hit the read link -- you definitely aren't alone in all of this.[Via WMPowerUser]
Cracks 'appearing' in new iPhone 3Gs
Let's be honest here for a second. Cracks don't appear. Cracks don't form. They don't develop. Your iPhone 3G cracked because you dropped it. 'Fess up! It's not a manufacturing defect if your phone takes a tumble down a flight of stairs. This is why we can't have nice things. Just kidding. Apple could have has another iPod nano or G4 Cube problem on its hands: careful users are seeing cracks and fissures on their new iPhone 3Gs. MacRumors has a thread about new, white iPhone 3Gs (which haven't been "dropped or pressed") that are beginning to show hairline cracks around the edges and near the buttons and headphone jack. Reasonably, though, if you treat it like a phone, and use it every day, it's going to get worn. That's when cracks, scuffs, and abrasions happen. When you have a white finish on your iPhone, dirt will inevitably get in there, and even the most minute scratch will show up. Every phone I've ever owned I've dropped at some point, and it gets a scuff, or a scratch or a crack. There are plenty of options to protect your sweetness, though: For example, there are all kinds of hard-shell cases you can buy. ZAGG's excellent invisibleSHIELD product is certainly durable, and could prevent dirt from getting into any fissures that appear on your iPhone's back cover. You can also wait a little while for the Golden Shellback, a vacuum-applied polymer that waterproofs any device, inside and out. Nifty. Update: Commenters are literally pouring in to tell us that as careful as they've been with their iPhone 3Gs, even the most babyed devices are showing cracks. Joel Renda says, "The problem is not the plastic, but that the metal frame is too small for the plastic to lock on without causing the stress fractures." It's pretty clear Apple has a manufacturing defect on its hands. For those with cracks, taking it back to the Apple Store (or possibly the mobile phone retailer where you made your original purchase) is your only recourse. Several people have noted here and elsewhere that they've successfully had their handset replaced after a careful inspection.
SplashTop instant-on OS hacked to run other programs, boot off flash drives
DeviceVM's SplashTop "instant-on" OS is based on Linux, even though it's locked down to only run IM, Skype, media software, and Firefox, and you know what that means -- it's already been hacked wide open. Yep, the clever kids at the Phoronix forums have managed to open up the BIOS-based OS and make it do all kinds of tricks, including run other programs and boot other machines off a flash drive. The hacks are still a little complex, but with ASUS shipping tons of ExpressGate-enabled mobos and laptops and HP's support in the Voodoo Envy 133, we'd there's a one-click unlocker in the wild fairly soon. Anyone brave enough to install it on their machines?[Thanks, george85]
iPhoneInterface starts to crack open iPhone
It looks like hacking the iPhone took a huge step forward last night. iPhone enthusiasts over at the #iphone-talk and #iphone-mac channels on irc.osx86.hu have developed iPhoneInterface, a new Windows and Mac tool that allows you to manipulate the iPhone's state, launch services, and interact with the iPhone filesystem. With it, you'll be able to scan the iPhone file structure, create and remove folders, start iPhone services, and more. It's still in its early days so don't expect too much from this first release. A public subversion server should be up overnight. Pop over to the irc channel for more information. Thanks to everyone on #iphone-talk, especially lixivial.
MIT's handheld FAR-NDT device sees cracks in structures
We've already seen radars come in handy when dodging impending attacks and avoiding accidents, but researchers at MIT are utilizing the technology to make sure our roadways and structures aren't pushed beyond their limits. A newfangled handheld device uses FAR-NDT (far-field airborne radar nondestructive testing) in order to "see through the fiberglass-polymer wrapping often used to strengthen aging concrete columns to detect damage behind the wrapping not visible to the naked eye." Furthermore, the technique can be executed from about 30 feet away and "requires no dismantling or obstruction of the infrastructure" in order to provide instant feedback. Unsurprisingly, creators are suggesting that it will be best used on bridges and piers which are typically difficult to carefully inspect, and while there's no word on when this stuff will hit DOT offices nationwide, current prototypes are panning out quite well.[Via Physorg]
ATM PINs vulnerable to cracking, Israeli researchers say
Everyone relies on their ATM cards pretty frequently -- after all, there's no better (or, often, more necessary) way to start your evening than with a $40 quickdraw from your favorite local money machine. Well, you may want to think twice (that is, if you're among the paranoid security-minded types) next time you whip out that thin piece of plastic. A group of researchers at Algorithmic Research (ARX), an Israeli security firm, published a paper two weeks ago describing a very serious flaw inherent in most ATMs. Apparently, between the time that you input your PIN and the time that the machine spits out your cash, a dataset containing your PIN and account number is encrypted and decrypted a few times while being routed along the banking network -- and somewhere along that point, it's conceivable that those numbers could be intercepted. MSNBC reports that while no attacks using this method have been detected, the US Secret Service is already on the case, and that while Visa and the American Bankers Association are acknowledging the problem, both are dismissing the hacking scenario as being unlikely. Still, we might consider busting out that money belt sometime soon, getting the USSS on the job means it could be big. [Warning: PDF link][Via MSNBC]
