Black Hat

Last week we had the opportunity and pleasure to present some of our research results at BlackHat US 2014 (besides of meeting a lot of old friends and having a great researchers’ dinner).

Enno and Antonios gave their presentation on IDPS evasion by IPv6 Extension Headers, described here.

The material can be found here: Slides, tools (the main tool used was Chiron, authored by Antonios) & whitepaper.

Ayhan and me presented our results of the security analysis of Cisco’s EnergyWise protocol. The protocol enables network-wide power monitoring and control (ie turning servers off or on, putting phones to standby — basically controlling the power state of all EnergyWise-enabled or PoE devices). The main problem (besides a DoS vulnerability we found in IOS, see official Cisco advisory) is its PSK-based authentication model, which enables an attacker to cause large-scale blackouts in data centers if the deployment is lacking certain controls (for example our good old favorite, segmentation…). There will be a longer blogpost/newsletter on this topic soon.

Hi,

if you’re following this blog regularly or if you’ve ever attended an ERNW-led workshop which included an “architecture section” you will certainly remember the “Seven Sisters of Infrastructure Security” stuff (used for example in this post). These are a number of (well, more precisely, it’s seven ;-)) fundamental security principles which can be applied to any complex infrastructure, be that a network, a building, an airport or the like.

As part of our upcoming Black Hat and Troopers talks we will apply those principles to some VoIP networks we (security-) assessed and, given we won’t cover them in detail there, it might be helpful to perform a quick refresher of them, together with an initial application to VoIP deployments. Here we go; these are the “Seven Sisters of Infrastructure Security”:
