24th USENIX Security Symposium & WOOT Workshop

Recently I had the pleasure to attend the 24th USENIX Security Symposium and its co-located Workshop on Offensive Technologies (WOOT) in Washington, D.C. The workshop has received quite some attention this year, 57 submissions of which 19 have been accepted, so that the organizers decided to double its length from one to two days.

Cisco and the Maintenance Operation Protocol (MOP)

Howdy,

this is a short write up about the Maintenance Operation Protocol (MOP), an ancient remote management protocol from the DECnet protocol suite. It’s old, rarely used and in most cases not needed at all. But as we stumbled across this protocol in some network assessments, it seems like a lot of network admins and other users don’t know about it. Even various hardening guides we’ve seen don’t mention MOP at all.

KNX Support for Nmap

Hi folks,

our home automation research, especially with KNX, is still in progress. As part of this research we’ve implemented various tools to easy the process of identifying and enumerating KNX devices, in both IP driven networks and on the bus.

Lately we’ve written two Nmap NSE scripts to discover KNXnet/IP gateways. These allow everyone to discover such gateways in local and remote networks and print some useful information about them. One of them follows the specification to discover gateways by sending multicast packets, where all devices on the network must respond to. Due to the specification of KNXnet/IP this process is rather non-invasive because only a single UDP packet is needed to discover multiple gateways. The other script allows to identify gateways via unicast connections by a slightly different message type, which allows discovery over e.g. the Internet.

The scripts are now publicly available and will (hopefully) be included in Nmap soon.

Currently we are working on a tool which allows to enumerate KNX devices on the bus either from an IP driven network over a KNXnet/IP gateway or directly on the bus. Additionally information about the discovered devices included in the bus system will be extracted, e.g. what kind of device it is a sensor or an actuator.

It is planned to be released soon, so stay tuned 😉

Black Hat Talks & Papers related to Windows/Active Directory Security

This year’s Black Hat US saw a number of quite interesting talks in the context of Windows or Active Directory Security. For those of you too lazy to search for themselves 😉 and for our own Windows/AD Sec team (who couldn’t send anyone to Vegas due to heavy project load) I’ve compiled a little list of those.
