A few people have been asking how Network Spoofer actually works; hopefully this explanation will allow people to understand its working and try out their own spoofs.

The Can you crack it? challenge, run by GCHQ, is ending soon, so here are a few hints to those trying to crack the code. I’ll try not to give too much away, but this should be a help to people who are stuck.

GCHQ recently opened a puzzle called ‘Can you crack it’, over at canyoucrackit.co.uk. The challenge is split into three stages, and here is my solution to Stage 2. The original task suggested the solution should be done with Javascript, however I decided to tackle this challenge with Haskell.

The challenge is to write a Virtual Machine to interpret a block of code given in the instructions – once the program is interpreted, the solution appears in the memory of the virtual computer. The code itself firstly decrypts a section of the memory; this decrypted block is itself a program which is then run by the Virtual Machine.

Solution: Download [tar.gz] [source code repo]

The program can be built using Haskell’s cabal command.

The latest release of Network Spoofer allows for multiple spoofs to be run at the same time – note however that this may considerably slow the whole process down on some phones. I’ve also added a new spoof which changes the text on webpages; this can be quite subtle and almost unnoticeable if similar words are changed.

For these new features to work the latest version of the extra files needs to be downloaded.

The latest version of Network Spoofer includes custom YouTube videos and custom images. Downloads available on the Android Market.

This version also includes Busybox; this should fix quite a few of the bugs reported. Any log output which includes the text ‘applet not found’ should be fixed.

See the Main Page for more info.

The new version of Patchworker adds support for images with multiple stretch areas – ‘n-patch’ graphics.

Downloads available on the main page.

Network Spoofer 0.7 has just been released onto the Android Market, and it fixes several crashes that have been reported.

I’ve included a new spoof as well, however if there is anything new you’d like to see in this program (new spoofs etc.) then leave a comment below.

The latest version can be downloaded from the Android Market.

Patchworker is a new application of mine which makes the process of creating images during Android development easier – it exports the correct sizes of images into the corresponding folders in an Android project and allows easy creation of 9-patch scaling graphics for Android. It also allows exporting of SVG images into multiple sizes, a process which can be quite tedious.

See the main project page for more info and downloads.

I had an old Toshiba Portege M100 laptop which I wasn’t using, and recently decided to put it to good use: as a digital photo frame, and extra computer screen. It displays photos from a file server, automatically turns on and off, and can be used as an extra PC screen.

I just released a new program for Android phones – Network Spoofer – it’s an application which lets you mess with the internet on other computers, and (currently) flip & blur pictures, change google searches, and redirect websites. Many more features will be added in the future.

A download is available from the Android Market – see the main page for more information. This is still a very early release – please say if you notice anything odd happening – it’s the only way I can improve and fix things!

Thanks to the developer of the Upside-down-ternet for the inspiration for this project.

Enjoy spoofing!
