KNXmap: A KNXnet/IP Scanning and Auditing Tool

Users of the KNX, a standard for home automation bus systems, may already have come across KNXnet/IP (also known as EIBnet/IP): It is an extension for KNX that defines Ethernet as a communication medium for KNX which allows communication with KNX buses over IP driven networks. Additionally, it enables one to couple multiple bus installations over IP gateways, or so called KNXnet/IP gateways.

In the course of some KNX related research we’ve had access to various KNXnet/IP gateways from different vendors, most of them coupled in a lab setup for testing purposes. The typical tools used for such tasks are ETS, the professional software developed by the creators of KNX (proprietary, test licenses available) and eibd, an open source implementation of the KNX standard developed by the TU Vienna.

Pentesting Webservices with Net.TCP Binding

Hi all,

Most of you that are  pentesters  may have already tested plenty of webservices using SOAP (Simple Object Access Protocol) for communication. Typically, such SOAP messages are transferred over HTTP (Hypertext Transfer Protocol) and are encapsulated in XML (Extensible Markup Language). Microsoft has developed different representations of this protocols to reduce the network load. As these representations/protocols aren’t really covered by typical tools out there, this post will show you some of them, and a proxy which can be used to simplify the testing.

SAMLReQuest Burpsuite Extention

Security Assertion Markup Language (SAML) is an XML standard for exchanging authentication and authorization data between a Service Provider (SP) and an  Identification Provider (IdP). SAML is used in many Single Sign-On (SSO) implementations, when a user is authenticated once by IdP to access multiple related SPs. When a user requests to access a SP, it creates a SAML Authentication Request and redirects the user to IdP to be authenticated according to this authentication request. If the user is successfully authenticated, IdP creates a SAML authentication response and sends it back to SP through the user’s browser.

unrubby: reversing without reversing

The talk “unrubby: reversing without reversing” was part of the Troopers conference in Heidelberg, 16 March 2016. The talk was done by Richo Healey, who is currently working on the security engineering team at the Irish payment company Stripe. Richo Healey is an experienced conference speaker. Amongst other he has spoken at Kiwicon, DEF CON and 44con.
 
In his talk Richo Healey spoke about reverse engineering of Ruby software. First he talked about existing tools and techniques to regenerate source code from Ruby bytecode. Then he presented a new concept, which is implemented in his tool “unrubby”.

Check your SAP landscape for default Solution Manager users

This is a guest post from Joris van de Vis @jvis,  on his upcoming Troopers talk. Additional credits go to: Robin Vleeschhouwer, and Fred van de Langenberg.

 

Picture1

As presented at Troopers this year, ERP-SEC research has uncovered a set of potential default accounts related to the use of SAP Solution Manager. These default accounts might pose a big risk to your SAP supported business as some of them have wide authorisations. It is therefore important to check if they exist in your landscape and change the default passwords.

How to crack a white-box without much effort

By: Philippe Teuwen (@doegox)

White-box cryptography is a relatively new field that aims at enabling safely cryptographic operations in hostile situations.
A typical example is its use in digital-right management (DRM) schemes, but nowadays you also find white-box implementations in mobile applications such as Host Card Emulation (HCE) and the protection of credentials to the cloud.
In all these use-cases the software implementation uses the secret key of a third-party which should remain secret from the owner of the device which is running this executable.

Python For Hackers

Python has reached a defacto standard in exploit development lifecycles and most of the proof of concept tools you’ll find out there are written in Python (besides the metasploit framework, which is written in Ruby). Python allows to write scripts handling with remote services, fiddling with binary data and interacting with C libraries (or Java in case of Jython/.Net in IronPython) in a fast and easy way. The huge standard library with it’s “battery included” principle removes some of the dependency hell known from other frameworks/languages. I want to share some of my python coding experiences with you, and maybe this could give some helpful tips for your future work, to make the world a bit safer 🙂 (PS: most of the examples are written in Python 3.x or compatible to both Python branches).
