More Troopers Talks Selected

Today we have to pleasure to announce another round of Troopers talks.
Here we go:

 
Noam Liram: Vulnerability Classification in the SaaS Era      FIRST TIME MATERIAL

Abstract: In this talk we will thoroughly analyze two major SaaS vulnerabilities that were found by Adallom (one of which is still in responsible disclosure stages at the time of writing). By demonstrating this new class of exploits which we have nick-named “Ice Dagger” attacks, we aim to change the current industry-wide criteria for vulnerability classifications, which were developed in the Desktop/Server world, are inadequate when classifying SaaS vulnerabilities. We will specifically discuss the details of MS13-104.

IPv6 Address Plan Considerations, Part 1: General Guidelines

In an upcoming series of blog posts I will discuss some principles & considerations on developing an IPv6 address plan. In (hopefully) rather quick succession there will be three posts:

  • the first  on some general rules as for IPv6 address planning which we regard instrumental in the process.
  • the second covering the “PI space from a single RIR or PI space from each (relevant, as for $ORG) RIR?” debate.
  • the third on actual approaches to structuring/grouping each region’s /32 (or /36) into subdivisions like sites, VRFs, facilities, use types, buildings, whatever. I understand that this part is probably the one quite some readers are most interested in; still for a reasonable line of thought the others have to be covered in advance.

As you might have already spotted from the prefix lengths mentioned above, the presumed setting (read: the main audience) of this piece is a sufficiently large enterprise organization with sites/subsidiaries/plants all over the globe, potentially mainly in the EMEA, APAC and Americas regions. So if you’re [with] a service provider organization, a university or small[er] organization, some of the recommendations I lay out might not apply to you. This focus (or restriction thereof) is for the simple reason of ignorance. Given I haven’t been involved in many address planning efforts in such organizations I don’t feel qualified to advance opinions on their settings.

Troopers 2014 – Third Round of Talks Selected

At first a very happy new year to all our readers!

Today we announce the third round of Troopers 2014 talks (first round here, second here).

Here we go:

Daniel Mende: Implementing an USB Host Driver Fuzzer         FIRST TIME MATERIAL

Abstract: The Universal Serial Bus (USB) can be found everywhere these days, may it be to connect a mouse or keyboard to the computer, transfer data on a flash drive connected via USB or to attach some additional hardware like a Digital Video Broadcast receiver. Some of these devices use a standardized device class which are served by an operating system default driver while other, special purpose devices, do not fit into any of those classes, so vendors ship their own drivers. As every vendor specific USB driver installed on a system adds additional attack surface, there needs to be some method to evaluate the stability and the security of those vendor proprietary drivers. The simplest way to perform a stability analysis of closed source products is the fuzzing approach. As there have been no publicly available tools for performing USB host driver fuzzing, I decided to develop one ;-), building on Sergey’s and Travis’ legendary Troopers13 talk. Be prepared to learn a lot about USB specifics, and to see quite a number of blue screens and stack traces on major server operating systems…

Troopers 2014 – Second Round of Talks Selected

We’re very happy to announce the second round of Troopers 2014 talks today (first round here).
Some (well, actually most 😉 ) of these talks haven’t been presented before, at any other occasion, so this is exciting fresh material which was/is prepared especially for Troopers.

 

Andreas Wiegenstein & Xu Jia: Risks in Hosted SAP Environments. FIRST TIME MATERIAL

**Synopsis: **Many SAP customers have outsourced the operation of their SAP systems in order to save cost. In doing so, they entrust their most critical data to a hosting provider, potentially sharing the same SAP server with a number of companies and organizations unknown to them. These companies and organizations virtually sit in the same boat, without knowing each other and without trusting each other. They all trust in the ability of their hosting provider to run their operating environment in a secure way, though.

ERNW Newsletter 42: Dangers of Disabled Pre-Boot Authentication in Corporate Environments

It’s been a long time… we just published an ERNW Newsletter. Here’s the abstract:

In order to protect sensitive data on corporate laptops, most companies are using full disk encryption solutions. While native encryption products like Microsoft Bitlocker, Apple FileVault and open source solutions like TrueCrypt were already heavily scrutinized by security researchers, many popular commercial third party products are to some point still black boxes.

In this paper, we discuss Check Point Full Disk Encryption (FDE) with active “Windows Integrated Logon”. Checkpoint FDE is a software package that is part of Check Point Endpoint Security and offers full disk encryption on Microsoft  Windows and Mac OS X systems. The “Windows Integrated Logon” feature reduces total cost of ownership by disabling pre-boot authentication. Check Point themselves warn about security risk associated with using this feature.

ACSAC 2013

Matthias and I currently have to pleasure to be at ACSAC, in New Orleans.
From my perspective, at ACSAC the usual conference visit side-effect of personal interaction with peers plays an even larger role than at many other events. In fact we met a number of people we hadn’t seen for quite some time and I could even clear a long unresolved debt (Hi Pastor! and thanks for those International Journal of PoC issues).

Troopers 2014 – First Round of Talks Selected

We’re delighted to provide the first announcement of talks of next year’s Troopers edition. Looks like it’s going to be a great event again 😉
Here we go:

==================

Toby Kohlenberg: Granular Trust – Making it Work

Over the last 5 years the concept of using dynamic or granular trust models to control access to systems, networks and applications has become well known and is now seeing partial adoption in many places. The challenge is how granular and dynamic can you get and the question is whether it is worth it. As the architect of Intel’s trust model Toby can speak to the entire journey from initial idea through current implementation and the likely road ahead. This talk will include the good, bad and ugly parts of designing a trust model and then implementing it in a Fortune 50 company’s production environment. You will learn from his mistakes so you can make different ones.

IPv6 Scanner

This is a guest post from Antonios Atlasis.

===

Having just finished the second “Advanced Attack Techniques against IPv6 Networks” workshop (some of the course material can be found here), organised and hosted by ERNW and their partner HM Training Solutions, I would like to take this opportunity to release publicly one of my scripting tools, an IPv6 scanner. This tool is based on Scapy (so you have to install Scapy and its prerequisites before using it). It should not be considered as a replacement or a competitor of nmap against IPv6 or of the scanners incorporated into the great IPv6 toolkits already released by Marc Heuse and Fernando Gont, but, instead, as a tool released mainly for educational purposes. Specifically, this scanner, apart from supporting some of the most well known port scanning techniques, from ping scanning to SYN, RESET, ACK, XMAS, etc., etc., TCP or UDP scanning, it also combines, by using the suitable switches, some IDS/IPS evasion techniques. As I have found out up to now, at least two of them, if used “properly”, can be effective against a very popular IDS/IPS software used by many “Fortune 100” companies out there. This means that you can launch actually any type of the supported network-scanning techniques while flying under the radar of this specific IDS software (and perhaps some other too, who knows…). But first of all, as always please check the corresponding README file.

IPAM Requirements in IPv6 Networks

I recently had a discussion with some practitioners about requirements to IP Address Management (IPAM) solutions which are specific for IPv6 networks. We came up with the following:

Mandatory: Track all dynamic IPv6 assignments (SLAAC + PrivExtensions, DHCP etc.), by polling neighbor caches from network devices. Support SNMPv3 for this task.
Optional (read: nice-to-have): support other methods than SNMP to gather this info (e.g. SSH-ing into devices and execution of appropriate “show” commands).
