Evasion of Cisco ACLs by (Ab)Using IPv6 – Part 2

When we wrote our initial blogpost regarding the evasion of Cisco ACLs by (Ab)Using IPv6, where we described (known to Cisco) cases of Access Control Lists (ACL) circumvention, we also suggested some mitigation techniques including the blocking of some (if not all) IPv6 Extension Headers.
Almost a month later, we got a comment from Matej Gregr that, even if the ACLs of certain Cisco Switches are configured to block IPv6 Extension headers like Hop-by-Hop or Destination Options headers, this does not actually happen/work as expected. Of course this made us re-visit the lab in the interim ;-).

The patient’s last words: I am not a target!

Last week I gave a short interview for Süddeutsche Zeitung on the security of medical devices. You can find it here. Unfortunately it is in German so I decided to sum up some of my key points that made it into the article and some that didn’t in this blog post.

BT SnoopCon

I had the honour to be invited to BT‘s SnoopCon, which is their annual internal conference for people involved with security at BT. There were several external and internal speakers and I was stunned by the quality of the talks and the collaborative atmosphere. Since this event is somewhat internal (even though I’m obviously allowed to talk about it), I won’t go into details, however there were two particularly great talks about military war games (which I personally enjoyed very much given my history in CTF contests) and PoS security.

I was presenting on our progress in the area of Connected Car security and presented the lessons we learned from our lab and the Troopers Connected Car Roundtable (which we will have again for TR16) and how they will influence our traditional pentesting approach when it comes to cars (slides can be found here).

Best,

Matthias

NANOG64

I recently had the pleasure to join the 64th NANOG (North American Network Operators’ Group) meeting in San Francisco, which can be understood as one of the largest Internet engineering conferences at all. It takes place three times a year at different locations in North America.

What I personally like about NANOG is its strong collaborative and cooperative character. It is not about single persons and also not too much about spectacular projects but more about discussing technologies, ideas, challenges and numbers. Every talk has a comparatively large time slot reserved for discussion, which is often more than fully used. Discussion is typically actively focused and is more time-consuming (and even more relevant) than the talk itself. Which often is intended by the community. The climate of discussion is almost always impressively polite and constructive, even for controversially discussed topics.

Internet Information Service 7.5 Hardening Guide

Internet Information Services (IIS) contains several components that perform important functions for the application and Web server roles in Windows Server. As it is designed to be used in an enterprise environment, the security of this system must be kept at a high level.

By default IIS implements a lot of basic security measures, but are these the relevant ones to protect your business? Continue reading “Internet Information Service 7.5 Hardening Guide”

IPv6 Adress Planning / Some Notes

In the course of a customer project I recently documented some thoughts and general objectives of IPv6 address planning, expanding on stuff I wrote a while ago in the series on “Address Plan Considerations”. An excerpt of that (newer) document can be found here. Due to the context it originates from it’s in German, still I hope it’s useful for some readers.
If you’re interested in the topic it might be a good idea to listen to Tom Coffeen‘s talk at the upcoming IPv6 Business Conference, too.

Everybody have a great day

An unpacker for Alcatel TiMOS images

Hi,

I wrote a small python script that extracts the content from Alcatel .tim firmware files. It took some time staring at hex values, as well as a fair amount of guess work to figure out the file format.

ERNW @PHDays V in Moscow

Здравствуйте Insinuator Followers,

End of May eight ERNW members were travelling to Moscow (Russia) to visit the PHDays V conference. It was a very nice trip because we met a lot of gentle people, ate some great food and had quite some fun in this exciting and history-charged metropole, and we were able to get around using hands and feet (and Google translate ;-)).

The remainder of this post contains summaries of some of the most interesting talks at PHD V:
