Check your SAP landscape for default Solution Manager users

This is a guest post from Joris van de Vis @jvis, on his upcoming Troopers talk. Additional credits go to: Robin Vleeschhouwer, and Fred van de Langenberg.

As presented at Troopers this year, ERP-SEC research has uncovered a set of potential default accounts related to the use of SAP Solution Manager. These default accounts might pose a big risk to your SAP supported business as some of them have wide authorisations. It is therefore important to check if they exist in your landscape and change the default passwords.

How to crack a white-box without much effort

By: Philippe Teuwen (@doegox)

White-box cryptography is a relatively new field that aims at enabling safely cryptographic operations in hostile situations.
A typical example is its use in digital-right management (DRM) schemes, but nowadays you also find white-box implementations in mobile applications such as Host Card Emulation (HCE) and the protection of credentials to the cloud.
In all these use-cases the software implementation uses the secret key of a third-party which should remain secret from the owner of the device which is running this executable.

Multicast Based IPv6 Neighbor Spoofing / Response Behavior on Cisco Devices

Dear readers,

today we want to examine the behavior of Cisco devices when they receive spoofed IPv6 Neighbor Advertisement packets from an untrusted system pretending to be the default router for the local segment. We start with a quick refresher how Cisco devices behave in the legacy (IPv4) world when they receive a spoofed broadcast ARP packet containing the IP address of the device but with a different MAC address, followed by a discussion of the corresponding behavior in the IPv6 world. Continue reading “Multicast Based IPv6 Neighbor Spoofing / Response Behavior on Cisco Devices”

Dual Stack vs. IPv6-only in Enterprise Networks

I had the pleasure to sit in Mark Townsley “Addressing Networking Challenges With Latest Innovations in IPv6” session at Cisco Live yesterday and – somewhat inevitably – there was a mention of Facebook having implemented an IPv6-only approach in their data centers (here’s a talk from Paul Saab/FB laying out details). So, with the “IPv6 Panel” looming, I started reflecting on “Why don’t we see this in our customer space?”. This post quickly summarizes some observations and thoughts.
