MegaUpload Captcha Cracking In JavaScript

January 23, 2009 by Eliot 25 Comments

This was certainly the last thing we expected to see today. [ShaunF] has created a Greasemonkey script to bypass the captcha on filehosting site Megaupload. It uses a neural network in JavaScript to do all of the OCR work. It will auto submit and start downloading too. It’s quite a clever hack and is certainly helped by the simple 3 character captcha the site employs. Attempting to do the same thing with ReCAPTCHA has proven much more difficult.

UPDATE: [John Resig] explained of how it works.

WiFi Theremin

January 23, 2009 by Eliot 9 Comments

The fine folks at Midnight Research Labs have put together a new toy for you to play with. It’s a Python script that makes your WiFi hardware behave more like a theremin. Based on the pyaudio library it monitors the signal strength of the AP you’re connected to and changes the tone accordingly. There’s a sample embedded above (direct link). If you have a second interface, you can use it to modulate the volume. It’s an interesting trick, but they say that there’s enough latency that it would be hard to play actual music with it.

We’ve covered a couple of different ways of doing choreographed Christmas lights. The most basic being sound activated ones made from speakers, then the parallax controlled ones. This one uses the parallax microcontroller as well, but [prabbit22m] seems to have put some more effort into the construction and enclosure. The lights are all LED this time around and there are 18 outlets that can be individually controlled in a nice, safe enclosure. The choreography was done well too. The capabilities video is pretty impressive, it looks like he has managed to do some fading in and out. You can see it after the break.

Surprisingly, one of the most common complaints we hear from people trying out macs are the fact that there isn’t a right click. The latest version, the unibody, has an option that remedies this, but older versions are stuck without. While you could always plug a USB mouse in, that is hardly a hacker’s solution. [spiritplumber] sent us this mod he did, adding right click functionality to his Macbook Pro. It is worth noting that this is meant for the 2006 to 2008 version of the Macbook Pro. You’re on your own for different ones.

[spiritplumber] points out that there are test points on the back of the track pad that emulate certain events. One of wich, just happens to be a right click. He shows us how to wire this, to a home made contact button under the right corner of the track pad. This can be potentially hazardous to your macbook, so be careful and follow his tips for soldering. If you want, you can do the same to the opposite side for your left click, or just leave it the way it is. You can see a video of it in action after the break.
