After some time without releasing any new version here is peepdf v0.3. It is not that I was not working in the project, but since the option to update the tool from the command line was released creating new versions became a secondary task. Read more »
As part of this year’s Summer of Code, I programmed an extension for the shellcode detection and analysis library libemu. The main goal of the project was to increase the performance when executing shellcode, with the help of a virtualizer. Prior to this extension, libemu made use of a custom emulator, which supported only instructions mostly used in shellcode. With this extension, libemu utilizes a full-blown, completely functioning virtualizer, which executes code presumably the same way a real CPU does. Read more »
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. Read more »

|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.

As libemu had it's second release (0.2.0) lately, I'll try to introduce it to the audience who did not hear about it yet.
libemu is a small library written in c offering basic x86 emulation and shellcode detection using GetPC heuristics.
Intended use is within network intrusion/prevention detections and honeypots.
