This Little USB Necklace Hacks Your Computer In No Time Flat

usb
Quick! The bad guy/super villain has left the room! Plug in a mysterious device that’ll hack up their computer while an on-screen progress bar ticks forward to convey to the audience that things are working!

It’s a classic scene from basically every spy movie in history. In this case, however, that mystery device is real.

Samy Kamkar — developer of projects like that massive worm that conquered MySpace back in 2006, or SkyJack, the drone that hijacks other drones — has released a video demonstrating the abilities of a particularly ridiculous “necklace” he sometimes wears around.


Called USBdriveby, it’s a USB-powered microcontroller-on-a-chain, rigged to exploit the inherently awful security flaws lurking in your computer’s USB ports. In about 60 seconds, it can pull off a laundry list of nasty tricks:

It starts by pretending to be a keyboard/mouse.
If you have a network monitor app like Little Snitch running, it uses a series of keystrokes to tell LittleSnitch that everything is okay and to silence all warnings.
It disables OS X’s built-in firewall.
It pops into your DNS settings and tweaks them to something under the hacker’s control, allowing them to replace pretty much any website you try to visit with one of their own creation.
It opens up a backdoor, then establishes an outbound connection to a remote server which can send remote commands. Since the connection is outbound, it eliminates the need to tinker with the user’s router port forwarding settings.
It closes any windows and settings screens it opened up, sweeping up its footprints as it heads for the door.
So in 30-60 seconds, this device hijacks your machine, disables many layers of security, cleans up the mess it makes, and opens a connection for remote manipulation even after the device has been removed. That’s… kind of terrifying.

While the video above focuses on OS X, the methods tapped here aren’t exclusive to Apple’s platform. Kamkar says everything shown so far is “easily extendable to Windows or *nix.”

So what can you do to protect yourself from things like this? Not a whole lot, really — that’s why attacks like this and BadUSB are so freaky. A lot of these flaws are inherent to the way the USB protocol was designed and implemented across so many hundreds of millions of computers; short of filling your USB ports with cement or never, ever leaving your computer’s ports unattended while out and about, there’s no magic fix.

How To Hide Text In Microsoft Word 2007, Reveal It & Protect It

Sometimes what we hide is more important than what we reveal. Especially, documents with sensitive information, some things are supposed to be ‘for some eyes only’. Such scenarios are quite common, even for the more un-secretive among us. You want to show someone a letter composed in MS Word, but want to keep some of the content private; or it’s an official letter with some part of it having critical data. As important as these two are, the most common use could involve a normal printing job. Many a time we have to print different versions of a document, one copy for one set of eyes and others for other sets. Rather than creating multiple copies and therefore multiple printing jobs, what if we could just do it from the same document?  That too, without the hassle of repeated cut and paste. We can, with a simple feature in MS Word – it’s just called Hidden and let me show you how to use it to hide text in Microsoft Word 2007. It’s a simple single click process. Open the docum...

Boom, the startup that wants to build supersonic planes, just signed a massive deal with Virgin

Have you heard about Boom? Boom is a relatively new startup that’s aiming to build something pretty crazy. They’re not building an app… or a social network… or even some new gadget for the Kickstarter crowd. Boom wants to build planes. Really, really, really fast planes. Specifically, they’re trying to design and build a supersonic passenger plane that goes 2.2x the speed of sound. If all goes to plan, they’ll be able to shuttle people from New York to London in 3.5 hours, and SF to Tokyo in 4.5. Sound crazy? I wouldn’t disagree. It’s worth noting that the company is in the very early days for something as intensive, massive, and hugely expensive as designing and producing a passenger aircraft. They’re still working on their first prototype, and hope to fly it by late next year. But it’s also worth noting that the team behind the plane has some serious talent in its blood: the company’s 11 employees have collectively contributed to over 30 aircrafts — having worked on thin...

Fun Tools to Translate Your Name into Japanese Calligraphy

Japanese calligraphy is an artistic writing style of the Japanese language. Its Chinese origins can be traced back to the twenty-eighth century BCE. Calligraphy found its way into Japanese culture in 600 CE and is known as the karayo tradition. For Westerners, calligraphy is forever fascinating. However, it takes years to learn how to properly draw the signs. Two basic principles must be known to understand Japanese writing: there are different writing styles and different alphabets. Kaisho for example, is a writing style most commonly used in print media. Tensho on the other hand is used in signatures. Other writing styles are Reisho, Gyosho and Sousho. The alphabets include Kanji, Hiragana, and Katakana. Katakana is used for writing foreign words. It can also serve to highlight words, in analogy to capital letters as we know them from the Roman / Latin alphabet (Romaji in Japanese). Each Kanji character has a meaning of its own, while Hiragana or Katakana characters merely repres...
