14:30 - 15:30 - (Practical) Escapism for the Modern Rogue.
This will be an on-hands workshop, detailing several methods of escaping from commonly used restraints. The workshop will mostly focus on bypassing flaws or features and exploiting weaknesses in the used restraint or material.
There will be a short introduction and demonstration, then the floor is open for practical application... on you! Practice while supplies last. This workshop is bound to keep you on the edge of your seat, figuratively or otherwise.
15:30 - 16:30 - Building the led-ball
Brainsmoke will tell us what he did do build his awesome led ball, capable of animations, high-framerates and intense brightness. What problems he found during development, and what tools (both at the hackerspace, and in china) he used to get the physical parts ready for "production".
16:30 - 17:30 - Making money with just one webpage
Juerd will explain how his one website makes him a decent part of his income (No recording of this talk, for privacy reasons)

14:00 - 15:00 - NetBSD Security Advisory 2013-008: tcpdrop networking security vulnerability explained
In August 2013, I held a talk at OHM2013 presenting and publicly disclosing a security vulnerability bug within the NetBSD operating system's kernel authorization framework ("kauth").
The bug was trivially easy to exploit, had been in NetBSD for over 3.5 years, and allowed local attackers to hijack a host's networking facilities. It got fixed by NetBSD at the start of the talk, committing a patch I provided as part of my earlier disclosure to NetBSD.
Exploit scenarios included completely owning a host by denying all remote service to all users (including root), locking out specific users of the host, and exercising more fine-grained filtering power, resembling a host based firewall. The talk included a video demonstrating some of these exploitations, as well as inner details about the bug and the kauth framework in general.
A famous blog covered the talk. Also, in the months following the talk, quite some people within the German hacker scene expressed their personal interest in the talk to me. Unfortunately, the recording of the talk turned out not to have succeeded.
The above, combined with the bug being as peculiar as it is, led to the idea of redoing the talk at another conference, preferably (but not necessarily) in Germany. A talk proposal or two got rejected though, and with that, redoing the talk more or less became a long term personal wish as well -- after a year and a half now getting fulfilled at eth0.
This talk will be in English.
A video recording will be made by eth0. The speaker kindly requests the audience not to make any additional recordings or pictures of the talk without asking consent beforehand.
