Not all of research & reversing tasks and solutions can be disclosed here due to our agreements with the clients. But more general info on our activity within research direction can be found in the Our Articles section.

In 2006 the team faced the following new and non-trivial tasks:

1. Research of communication protocols for Symbian-based Nokia smartphones. It was mRouter, in particular.
2. Research of FFS file system in Samsung phones of Agere generation
3. Research of the ways of getting a file system dump on WinCE devices
4. Research of communication protocols for the Motorola mobile phones which have M-Core processors.

The team can be proud of such facts:

1. The processor module for analysis of M-Core code was developed;
2. The loader of a code of Symbian OS insertions was developed;
3. Recreation of the stack of Symbian mRouter protocols was conducted.

The most useful new skills and developments of the year 2006 are:

• A new approach for reversing of complex systems.
  Within the limits of this approach the linker assembles a code by modules. To simplify a reversing task for yourself, it is necessary to select the module borders in the executable file. Then you need to take out this piece of code in a separate file and reverse it there as absolutely new file. The aspect is mostly psychological, because if you have a file of 30 Mb size, it frightens - there is a chance to not notice something, miss, and you can be bogged down in all this periodically. When you have 50Kb of code, it is easy to handle with.
• OS Symbian architecture was researched. Methods of working with hardware of Motorola M-core phones were found.
