ERNW @BlackHat US 2014

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.
