Introduction

Time flies. Almost 3 weeks have passed since we announced the ability to run mona.py under WinDBG.  A lot of work has been done on mona.py in the meantime.  We improved stability and performance, updated to pykd.pyd 0.2.0.14 Read more

Ho Ho Ho friends,

It has been a while since we posted something on the Corelan Team blog, I guess we all have been busy doing … stuff and things, here and there.  Nevertheless, as the year is close Read more

Good morning,

Since doing live-blogging seemed to work out pretty well yesterday, I’ll do the same thing again today.  Please join in for day 3 at BlackHat Europe 2012, in a cloudy and rainy Amsterdam.

The first talk Read more

Recently I played with an older CVE (CVE-2008-0532, http://www.securityfocus.com/archive/1/489463, by FX) and I was having trouble debugging the CGI executable where the vulnerable function was located. Read more

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. Read more

On June 14, 2011 HD Moore announced the Metasploit Bounty contest, offering a cash incentive for specific vulnerabilities to be submitted as modules in the Metasploit Framework. Titled "30 exploits, $5000 in 5 weeks", a post on the Rapid7 blog lists the 30 "bounties" selected by the MSF team, waiting for someone to claim and submit a working exploit module. Read more

Aloha, Again I stumbled upon a nice reverse-me, binary200 from the Codegate 2011 CTF. And again there are some really interesting anti-debugging tricks implemented, so I decided to produce another video. Read more

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.
