What did I do yesterday in the evening?
Well, I patched the [typosphere](http://www.typosphere.org) converter for movable type and migrated my blog :)
I just needed something to play with
IPTV Application Zattoo now offers the whole bunch of ARD + ZDF Channels (including ZDF Documentation Channel) :D
I remember the first jailbreak I did back in November 07. It involved lots of reading, downgrading to an old firmware, using the wellknown jailbreakme.com tif exploit, octoprep and a bunch of other stuff. Luckily I didn't have to unlock the phone to use it with another carrier, that would really have been a pain in the ass.
The iPhone-Hacker community has come a long way since then and I'm impressed on a weekly basis of the stuff they manage to push out on the web.
- The software is a self contained application (for MacOS 10.4.x and 10.5.x) that allows all current models of the iPhone device to be "Pwned";. This term (in relation to this software) refers to the patching of the stock bootloader so that it will allow the execution of unsigned code and circumvent code-signing checks. "Pwnage"; only needs to be performed once to allow the additional features on the iPhone.
- The application also processes and modifies existing Apple archives so that unique, custom rolled firmware bundles can be installed onto the "Pwned"; iPhone directly from iTunes.
- These ".ipsw"; files can be created and patched by the application to allow third-party modifications such as activation, application installation, baseband modification, custom phone graphics etc.
- The tool works automatically on box-fresh (OTB) 1.1.3 and 1.1.4 iPhones and requires minimal interaction from the user.
The tool also ships with an iPhone application that is automatically installed and run on first boot (if the user requests it) that is called "BootNeuter";, This will enable "Bootneutering"; of the iPhone baseband allowing custom firmware to be installed. Arbitrary secpacks and fls files will be accepted when the device is in this state, please refer to the application help file for specific information.
If the user has access to developer versions of the iPhone software (such as 1.2 or 2.0) provisions have been made to support this software and allow it to be used on any device. This will be useful for legitimate SDK trialists to install their software on more than one device, this should not be used unless you are an official member of the SDK programme.

I never really got all the big blog-announcements when truecrypt was released for OS X. Everybody went crazy because of the ability to encrypt partitions on OS X. The windows version has a nice preboot authentication feature and the "native"; encryption options (bitlocker and EFS) were both created by Microsoft which makes it quite understandable that people tend to like truecrypt on windows.
On OS X you imho don't really need truecrypt. OS X has built in support for encrypted dmg files.
They mount like regular diskimages (given that you know the password), they are encrypted with the AES algorithm in either 128 or 256 bit strength and on my slow laptop drive, on the fly encryption doesn't really slow thoughput down thaaat much. If you've got a faster drive (e.g. 3,5" external HDD): do you really permanently move data or do you simply put it on the drive and access it every other week?
To create such an image you have to take several things into consideration:
- Would you like to create a sparseimage?
The image will grow to a given size but only take as much space as the amount of data it currently hosts. The only problem is, that once you delete something inside the image, you'll manually have to do a "compact"; (using hdiutil) in order for "empty"; space to be readded to your partition —> sparseimages will grow automatically up to a given size, but shrinking is a process that has to be done manually.
If you plan on encrypting an external HDD, you shouldn't use a sparseimage because resizing will take some time and you'll use the whole HDD anyway most of the time.
- AES128 or AES256? (Both should be secure, AES256 is slower)
On my Macbook's internal harddisc, I simply want to have a secure store for some files that shouldn't be seen by everybody.
I created a sparseimage and set the maximum size to the size my harddisc has. That way, I can put as much files in there as I want to, only limited by the size of the HDD. I set the encryption to AES128 because I don't see the necessity to use AES256. AES128 is practically unbreakable and therefor secure enough for my files).
To create an encrypted dmg, simply fire up "Disk Utility";:
Select “new image”;:
You’ll be presented with a bunch of options:
For the volumesize I set a size of 80 GB (can be resized later afaik):
I set the encryption to 128 bit:
For the Image-Format, I chose a sparse Image:
You’ll have to specify your password now.
When mounting the image later on, it’ll look like this:
Here are the proposed dates for the days. 11.4.2008 – Test and Quality Day 25.4..2008 – Security day 30.5.2008 – Web Development day 13.6.2008 – Games Day
Here are some ideas for special days in the (short) summer term.
Games Day with a focus on game development, communities, collaboration etc.
Security Day with a focus on risk assessment, dealing with risk etc. How do we handle risk rationally? Another topic could be anonymity.
Test and Quality Day with talks on web application testing, methodology and tools.
Web Development Day: the latest in languages (Ruby on Rails etc.) and tools in web development.
Here are the proposed dates for the days.
11.4.2008 – Test and Quality Day
25.4..2008 – Security day
30.5.2008 – Web Development day
13.6.2008 – Games Day
