on in security tools. There are some tools that have some visualization, but it is limited and lacks features.

He then takes us through the hall of fail of visualizations and gives us some tips on visualization.

Thinks as a designer, be aware of who you are visualizing for. Each group has different demands for visualization and want to take different things out of it.

He then proceeds to give us some tips and tricks. He recommends to follow the work of Edward Tufte and Stephen Few who have both done excellent work on data visualization.

If you do data visualization you may want to get data from external reports like osvdb.org datalossdb.org and other industry vendors.

Common problems of data visualization are redundant elements like 3D and color. This is expressed in the ink-to-info ratio. You may want to reduce the bell and whistles you use.

Dashboards are often messy, they should really be aware of their screen real estate. Most important places on the screen are top left and the center of the screen. In order to squeze as much info as possible into a dashboard dashboard often get messy.

Black Hat EU: Web Application Payloads – Andres Riancho

talk focuses on the w3af project, which has been Andres project for a long time, but is an open source project. It can be found at http://w3af.sourceforge.net/

Andres starts by giving an overview of w3af.

He then goes into a scenario which is common for a pentest. It starts with a pentester discovering a arbitrary file read vulnerability in a PHP application, but how to proceed to getting root? There appears to a shocking lack of post exploitation tools that can be applied to web application vulnerabilities.

Why is there such a lack of post exploitation tools for web applications?

  • Buffer overflows used to be more common then web application flaws
  • Web applications only allow you to interact with the system in a specific (restircted) manner

Post exploitation of web applications requires a new mindset, because you are often restricted to one or a few functions, e.g. read files with restricted privileges or write files to specific areas.

BlackhatEU : Virtual Forensics
By Christiaan Beek

What are the challenges when you have to do forensics on a virtual environment?
•    What are the tools available?
•    Are the tools forensically sound?
•    Where is the data?
•    Who owns the data?
•    What forensic techniques do we use?
•    How to acquire data from the cloud?

Citrix is a nightmare for forensics investigators. There is no personal hard disk to investigate, only a personal profile which does not have very much data in it.

BlackHatEU : Universal XSS via IE8s XSS Filters

April 15th, 2010 No comments

By David Lindsay & Eduardo Vela NavaInternet Explorer

The talk is about abusing the anti-XSS filters built into IE8 to always be able to perform XSS.

Microsoft decided to implement anti-XSS measures in IE because XSS is so common. On the other hand the wanted to be careful not to break the web and to keep things performant and the solution itself had to be secure.

So how do these filters work?
•    Examine all outbound requests for XSS patterns using heuristics filters.
•    If something matches the filter a dynamic signature is generated
•    If the signature matches then the response is neutered.

BlackHatEU : Abusing JBoss

By Christian PapathanasiouJBoss logo

Christian demoed two tools called JBoss-autopwn and Tomcat-autopwn.

For both tools he demonstrated that exploitation is possible both on Windows and Linux systems. It is also very likely that his tool also works on Solaris.

BlackHatEU : Misusing Wireless ISPs for Anonymous Communication

The talk starts with explaining the properties of Satellite ISPs. Due to the nature of satellite communication, high latency, high downstream bandwidth, the ISPs often use performance enhancing proxies. Often the satellite ISPs use asymmetric links, using a local uplink in combination with the satellite downlink, but symmetric communication, where the uplink also is sent via the satellite is possible too.

The performance enhancing proxy on the local machine has to breaks some of the basic TCP/IP properties to enhance performance, in this also breaking some of the basic security measures.

BlackHatEU : Hacking Cisco Enterprise WLANs

When implementing Cisco Wireless network infrastructure Enno and Daniel got the impression that, security wise, these systems smell.

First part of the presentation focuses on what a typical implementation looks like.

There are three generations:
1.    Structured Wireless-Aware Networks (SWAN)
2.    Based on managed APs and LWAPP (After acquiring Airport)
3.    Cisco Unified Wireless Network

The talk focuses on generation one and three.

BlackHatEU : SCADA and ICS for Security Experts: How to avoid being a Cyber Idiot

April 14th, 2010 3 comments

By James Arlen (@myrcurial, james.arlen@pushthestack.com)Scada

James talk is not about SCADA, it about talking about SCADA.

The security industry has discovered that SCADA systems are in fact information system and all of a sudden security professionals are talking about how they can fix the SCADA security issues.

One of the biggest pieces of FUD that is out there is: if you own the computer you own the system? This is not the case, most of the time when SCADA systems fail, the processes they control stop.

Yes, SCADA systems use control processes by using standard protocols, like modbus tcp, but that doesn’t mean that you understand what energizing coil 13 does to the actual process. If you can break the computer system, it doesn’t men you can break the process.

There are more controls in place in a manufacturing process, e.g. the safety systems that are their to prevent catastrophic from happening or the quality control systems that prevent that dodgy products get out. The most important control in place is that manufacturing is still mostly run by humans who will notice that stuff is about to go wrong.

One of the facts about big infrastructures (electrical nets and manufacturing processes) is that the people who run them count on stuff breaking down. Most of the time you don’t even notice that a major failure in these systems has occurred.

It’s not all negative…
We can understand SCADA systems and we can indeed help. In industrial systems Availability is the key element of the triad, not Integrity or Availability.

If you are going to get involved, be a student, before you become the teacher. Buy some people a cup of coffee and be prepared to put you ego behind you. Understand that these people have being doing this work for a long time and are indeed you parents age, that makes you the kid.

James shared, not for disclosure, a number of examples of IT Security bad practices that where found in the real world and make most IT Security wince and giggle at the same time. Words like rsh, solitaire and non-upgradable NT 4.0 where mentioned.

What will save us, Super Ninja’s, l337 super heros or just “Not Sucking”.

As IT Security people we need to open up, understand this stuff and make small progress that will have a big effect.

BlackHatEU : Fireshark – A tool to Link the Malicious Web

April 14th, 2010 No comments

By Stephan Chenette (schenette@websense.com)fireshark

This talk is accompanied with the release of Fireshark, a Firefox plugin. It can be downloaded here: fireshark.org

Compromised legitimate websites have increased 225% in the last 12 months.

Stephan wrote the Fireshark too to address the problem of analyzing malware serving legitimate site. He found that to date there was no tools that are available today gave him the information that he needed.

Most malware landing pages use exploit kits that will try to use about 25 exploits. These kids are highly obfuscated. Most analysis tools are well known by the bad guys and are thus protected against de-obfuscation.

What is Fireshark?

BlackhatEU : Unveiling Maltego 3.0

April 14th, 2010 No comments

By Roelof TemminghMaltego logo

Maltego 3.0 will be a major upgrade. The first upgrade that shows is in terms of the visual representation. The Windows based GUI no longer looks like a port from a Unix application to Windows, but has a far more Windows look and feel to it and supports dynamic graphing. The user interface is now fully interactive in all views.

Enhancements include:
•    Dynamic graphs
•    Manual object linking
•    Infinite transfors (e.g. to follow tweets as they occur)

But is not just user interface changes, Maltego v3 will also handle so called “Dead End Entities” entities that currently don’t have transforms.
