Exploit writing tutorial part 11 : Heap Spraying Demystified
A lot has been said and written already about heap spraying, but most of the existing documentation and whitepapers focus on IE7 or older versions.
Although there are a number of public exploits available that target IE8, the exact technique to do so has not been really documented in detail.
Of course, you can probably derive how it works by looking at those public exploits.
With this tutorial, I’m going to provide you with a full and detailed overview on what heap spraying is, and how to use it on old and newer platforms.
I’ll start with some “ancient” techniques (or classic techniques if you will) that can be used on IE6 and IE7.
We’ll also look at heap spraying for non-browser applications.
Next, we’ll talk about precision heap spraying, which is a requirement to make DEP bypass exploits work on IE8.
I’ll finish this tutorial with sharing some of my own research on getting reliable heap spraying to work on IE9.

Honeynet Workshop 2011
March 21th I was in Paris for the annual Honeynet Workshop. For the first time this year there was a conference day accessible to the general public. Moreover, I didn’t have to pay the registration fee since I successfully completed one of the Honeynet Forensics challenges. The day was split in 4 sessions and had talks covering the Honeynet projects, malware, and ethical and legal considerations of tracking botnets and eventual take-downs.

The Honeypot Incident – How strong is your UF (Reversing FU)
Interested in capturing, documenting and analyzing scans and malicious activity, Corelan Team decided to set up a honeypot and put it online. In the first week of december 2010, Obzy built a machine (default Windows XP SP3 installation, no patches, firewall turned off), named it “EGYPTS-AIRWAYS”, set up a honeypot + some other monitoring tools, and connected it to the internet.
