A new improvement in PHoneyC DOM emulation code was committed in SVN r1624. The idea is to better emulate the DOM behaviour depending on the selected browser personality. Let's take a look at the code starting from the personalities definition in config.py.
A few weeks ago I started reviewing the PHoneyC DOM emulation code and realized it was turning to be hard to maintain and debug due to a huge amount of undocumented (and sometimes awful) hacks. For this reason I decided it was time to patch (and sometimes rewrite from scratch) such code. These posts will describe how the new DOM emulation code will work. The patch is not available right now since I'm testing the code but plans exists to commit it in the PHoneyC SVN in the next days.
I have finished almost all the coding stuff of Project #1, now you can try out the new PHoneyC with shellcode/heapspray detection here:
Please feel free to report any bug or suggestion on shellcode/heapspray detection to me.

|Description:||Mid-term Report on PHoneyC GSoC project 1. This report
describes what I have done on the PHoneyC's libemu integration
for shellcode and heapspray detection during the first half of
the GSoC. Till now, the main ideas on this feature has been
fast-implemented (actually I mean poor coding style) and the
whole flow works well, with some code rewriting and performance
optimization needed in the future.
