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.

Droid gets a USB hack allowing it to control printers and cameras, humans put on alert
Time to resurrect that old Droid Does chant, folks. Already headed for Android 2.1 from official sources, the Droid is gettings some extra software capabilities courtesy of a few benevolent UK hackers as well. Chris Paget has revealed a mod for Motorola’s flagship that turns it from a USB peripheral into a USB host, thereby letting it communicate with and control USB devices that speak the Linux language. That includes printers, webcams, and the vast majority of other things you typically jack into your computer. Mind you, this is one hack that’ll require you to get your hands dirty, as you’ll need to splice a few cables together and reboot your phone to switch between modes, but that’s how real modders do it anyway, right?

VisualBoyAdvance turns your Palm Pre into a Game Boy emulator
A certain UK bank operates a delightfully dorky advertising campaign whose slogan is “we give you extra.” Well, in the case of mobile software communities, that’s exactly the case. From jailbroken iPhones to PS One-emulating HD2s to multitouch-enabled browsing on the Nexus One, the one group of people we know we can truly rely on are other geeks. So let’s salute those heroes once more, in recognition of the VisualBoyAdvance — a webOS-based emulator for Game Boy, Game Boy Color and Game Boy Advance games. The former two categories are said to play smooth as you like, whereas the Advance stuff suffers from slight slowdown at present. We’ve only seen it playing on a Pre, but there should be no reason why your Pixi wouldn’t be allowed in on this party. A quick video demo awaits after the break, and the source link has all the installation details you’ll need.

Nexus One gets a custom ROM
It’s been but a week since the gang at Modaco rooted the Nexus One — and what do we have here? A quick visit to the self-same forums today has revealed that the handset has a new custom ROM. Based on the 22607 release (in case you’re curious), this bad boy sports many new and exciting features, including the Nano 2.09 text editor, wireless tether, Titanium Backup, Busybox 1.15.3, and more. Feelin’ adventurous? Hit the source link to give it a go. And make sure you drop us a line and let us know how it goes. (You don’t think we’re going to be the first to try it, do you?)
[Thanks, Jules]

Milestone multitouch browser ported to the Droid by a user-made patch (video)
This little nugget of software is itself still in beta, but if you can’t wait for the full Milestone firmware port to climb out of alpha development, it’s a good alternate route to getting your Droid dancing in the “pinch to zoom” party. Once again produced by the good folks over at AllDroid, the patch substitutes the Droid’s default browser with the Milestone’s multitouch capable one — and from the feedback we’re seeing it does so very cleanly and painlessly, whether you’re running Android 2.0.1 or 2.1. You’ll still need to root your device first, and some background reading is advisable before jumping in, but then you should be clear for take-off into the world of multitouch browsing. Video evidence after the break.
[Thanks, Steve]

Hardware accelerated ‘Doom’ comes to the Pre
Pre homebrew has certainly come a long way in its short but happy life — and now it’s just gotten another little notch in its belt. Apparently, with the release of webOS 1.3.5, Palm has included a software library called SDL (or Simple Directmedia Layer) which allows developers low-level hardware access — like the kind needed to tap into accelerated 3D graphics. With a little bit of elbow grease, webOS hacker extraordinaire zsoc was able to put together a port of Doom which can be run within a card in the OS, and completely functions (including keyboard controls). You’ve got to get your hands a little dirty with the Terminal app to make things happen right now if you want to try it for yourself, though the experimenters promise an easier solution in the coming days. Exciting stuff for webOS users hungry for a little more horsepower… now let’s see if Palm puts this into play come CES.
Update: PreCentral has a video of the app in action — check it out after the break!

Nexus One rooted already?
No, you still can’t have one (not yet, at least), but we’ve received a number of tips directing us Modaco forums, where admin Paul claims to have rooted Google’s not-so-mysterious Nexus One. We can’t validate the “superboot” file works, but the adjacent picture has popped up from another forum member as apparent anecdotal confirmation. Instructions for Windows, Linux, and OS X users can be found along with the necessary materials. What do you say, hacker community, any chance we can get multitouch loaded into the device before it ever becomes official to the world at large?
