During a recent customer project we identified several vulnerabilities in the VMware vRealize Automation Center such as a DOM-based cross-site scripting and a missing renewal of session tokens during the login. The vulnerabilities have been disclosed to VMware on November 20th, 2017. A security advisory for the vulnerabilities has been made available here on April 12th, 2018.

In various scenarios it might be helpful or even required to have a statically compiled version of Nmap available. This applies to e.g. scenarios where only limited user privileges are available and installing anything to the system might not be desirable.Continue reading
In this article, we describe the impact of the increased use of Docker in corporate environments on forensic investigations and incident analysis. Even though Docker is being used more and more (Portworx, Inc., 2017), the implications of the changed runtime environment for forensic processes and tools have barely been considered. We describe the technological basics of Docker and, based on them, outline the differences that occur with respect to digital evidence and previously used methods for evidence acquisition. Specifically, we look at digital evidence within a Docker container which are lost or need to be acquired in different ways compared to a classical virtual machine, and what new traces and opportunities arise from Docker itself.Continue reading
A new ERNW whitepaper was just published. I wrote this whitepaper in the course of my bachelor thesis and it examines multi-factor authentication in Microsoft Windows environments: Continue reading “White Paper on Multi-Factor Authentication in Microsoft Windows Environments”Continue reading
the last post was about a fuse filesystem which provides a read-only access to the proprietary bluecoat filesystem. After some further investigations based on the possibilities this offered us, I started to implement a tool which allows to modify parts of the filesystem.Continue reading
A while ago I wrote a short paper laying out options for an enterprise organization to get global IPv6 address space from the RIPE NCC, discussing the advantages and disadvantages of different approaches. As I think the topic may be of interest for others, too, I’ve distilled an anonymized version. It can be found here. I hope some of you find it useful.

As you may remember, back in 2014 we published a whitepaper (compiled by Antonis Atlasis) on the support of IPv6 in different pentesting tools. This is almost three years ago and we thought it is time for an update. In short not much has changed. Most of the tools which didn’t support IPv6 are still not supporting it or haven’t got any update since then.
This post will cover the tools where we could identify some progress on supporting IPv6.
Just recently we discussed IPv6 filter rules for NIC-level firewalls (in a virtualized data center) with a customer. I’d like to take this as an opportunity to lay out potential approaches for local packet filtering of IPv6, which in turn might somewhat depend on the address configuration strategy chosen for the respective systems (for the latter you may refer to this post or to this talk from the Troopers NGI event).Continue reading
Following Enno’s research on “Testing RFC 6980 Implementations with Chiron“, we decided to redo the experiment with FreeBSD targets.Continue reading
27 April 2016 marked a turning point for a lot of countries as well as a lot businesses worldwide: EU regulation 2016/679 (going by it’s more widely known name General Data Protection Regulation and abbreviated GDPR) was adopted by the European Parliament, the Council as well as the Commission . Especially readers from countries outside of the EU might ask “Why should this be of interest for me?”. Continue reading “GDPR and Pseudonymisation – Easing the Pain of Regulation”Continue reading
