“Nein! Ein von unbeugsamen Galliern bevölkertes Dorf hört nicht auf, dem Eindringling Widerstand zu leisten.”
This is a famous quote pretty much every German kid used to know. Not sure if this still applies though, my three haven’t touched Asterix comics so far. Anyhow, you might ask why I cite this.
Simple answer: see this recent article from the Guardian on a Utah-based ISP “resisting some pressure”. That’s the spirit…
Have a great Sunday everybody,

When teaching courses on topics like Reverse Engineering or Malware Analysis we always emphasize the need to minimize unneeded work. Because reversing an unknown binary is a time consuming and complex process, tools that simplify the RE process are invaluable when working under time pressure. In this blogpost series I will present multiple tools and techniques that can help to reverse an unknown binary. Please note that these articles do not contain cutting edge research but rather target at newcomers. However, I hope to also provide some useful and interesting information for moreexperienced practitioners.

EMET defines via “certificate trust“ a trust chain between the domain name of a website (and its associated website certificate) and a root CA certificate. This is done through so called “pinning rules”. Here is one of the default pinning rules of EMET 4.0 for the domain name login.live.com:

**we hope you’re doing fine! Today we have a couple of great things to share
with you:
TROOPERS14
Let’s start with a date. Get your calendar and mark March 17th – 21st 2014.
It’s your TROOPERS14 holidays. One week full of high-end education, workshops,
talks, reconnecting with friends, action, delicious food and one or the other
party. You know the drill – more details further down.
After his great presentations on IPv6 Extensions Headers and security problems related to fragmentation we had invited Antonios Atlasis to Heidelberg to give this workshop at ERNW. It was a great experience with many fruitful discussions between the participants (mostly security practitioners from very large organizations planning to have their Internet edge IPv6 enabled within the next 6-12 months) and him/us. Antonios thankfully decided to make his slides and scripts available for those interested in further research on the topics (it should be noted that the scripts have not been tested thoroughly and he’s happy to receive feedback of any kind at antoniosDOTatlasisDOTgmailDOTcom). Today Marc (Heuse) gives his workshop on pentesting in the IPv6 age. Hopefully such events help to move things into the right direction in the IPv6 security space…

MS just released a new guide on securing Active Directory. At the first glance seems a fairly comprehensive document to me.
At this occasion I may furthermore draw your attention to our (German language) newsletter no. 40 covering hardening MS Windows Server 2008 + AD.
have a good one,
Enno

From
15th – 17th of May, the sixth Google I/O conference took place in San Francisco,
California and I was one of the lucky guys attending. More then 5500 people,
primarily web, mobile, and enterprise developers, attended this annual event. A
lot of presentations included announcements of new and exciting technologies,
APIs as well as of two new devices.
During the first minutes of the keynote some of Google’s managers announced that by now over 900 million Android devices are activated and that 48 billion apps are installed, which demonstrates that this market is still heavily growing. As the major part of the audience were (app-) developers, these numbers were received quite greatfully and euphoric.

as we’ve received quite some requests re: the videos from Troopers 2013: the YouTube playlist can be found here.
Have fun (and learn something ;-)) watching, cu next year

Continue readingIn the course of a current virtualization research project, I was reviewing a lot of documentation on hypervisor security. While “hypervisor security” is a very wide field, hypervisor breakouts are usually one of the most (intensely) discussed topics. I don’t want to go down the road of rating the risk of hypervisor breakouts and giving appropriate recommendations (even though we do this on a regular base which, surprisingly often, leads to almost religious debates. I know I say this way too often:I’ll cover this topic in a future post ;)), but share a few observations of analyzing well-known examples of vulnerabilities that led to guest-to-host-escape scenarios. The following table provides an overview of the vulnerabilities in question:
