ROP your way into B-Sides Las Vegas 2011

Ahh.. Vegas.. What happens in Vegas, stays in Vegas right ?

With a variety of cons ahead (BlackHat, Defcon, B-Sides, …) there is plenty of things that can and will happen at Vegas. Will you be there to witness & enjoy it ?

Getting to Vegas is just one part of the story. Getting access to one of the cons is the second part, but in case of B-Sides, there are no tickets left anymore.
So, in case you were not able to get one of the free tickets to B-Sides LV, there’s good news !

We have 2 tickets for B-Sides LV (august 3 & 4, 2011)… and we’re giving them away…but not without a little ‘battle’…

Universal DEP/ASLR bypass with msvcr71.dll and mona.py

Over the last few weeks, there has been some commotion about a universal DEP/ASLR bypass routine using ROP gadgets from msvcr71.dll (written by Immunity Inc) and the fact that it might have been copied into an exploit submitted to Metasploit as part of the Metasploit bounty.

I’m not going to make any statements about this, but the ROP routine itself looks pretty slick.

Mona 1.0 released !

FINALLY !
After spending almost 6 months of designing, developing and testing, and after ‘surviving’ 2 presentations (at AthCon and Hack In Paris), I am extremely excited and proud to present, on behalf of the entire Corelan Team, the general availability of mona.py.

With this announcement, we also declare pvefindaddr officially dead from this point forward. (This doesn’t mean pvefindaddr is now entirely worthless, because not all functions have been ported into mona yet, but we won’t be releasing any updates to pvefindaddr anymore and the entire project page/download page will eventually disappear)

Hack Notes : Ropping eggs for breakfast

Introduction I think we all agree that bypassing DEP (and ASLR) is no longer a luxury today. As operating systems (such as Windows 7) continue to gain popularity, exploit developers are forced to deal with increasingly more memory protection mechanisms, including DEP and ASLR. From a defense perspective, this is a good thing. But we […]

BlackHat Europe 2011 / Day 02

BlackHat Europe 2011 / Preview

Things change.
11 months have passed since a lot of people found themselves trapped all over Europe (including Barcelona) because of a little volcano ash cloud thingy.

This is 2011.

This time BlackHat anticipated and outsmarted nature by rescheduling the Europe briefings to march (instead of april).

Cheat sheet : Installing Snorby 2.2 with Apache2 and Suricata with Barnyard2 on Ubuntu 10.x

After spending a few hours fighting a battle against Snorby and Apache2 + Passenger, I finally managed to get it to run properly on my Ubunty 10.x box (32bit). Looking back, I figured I might not be the only one who is having issues with this.

So I decided to publish the notes I took while setting everything up, and as a little bonus, explain how to install and configure Suricata as well (configured in combination with barnyard2 which will pick up local logs and send them to the remote MySQL server).

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.
