What you perceive used to be my homepage. But though the notion of a
homepage was novel a few years ago, today it seems more fitting to
refer to it as a contribution to the worldwide information

Some research that I do and projects that I work on:
-
dnsscan - a fast scanner for identifying open recursive dns resolvers
-
SpyBye - helps web masters determine if their web pages have been compromised and install malware.
-
Netlayout, a physics driven network topology
visualization tool.
-
Systrace, interactive policy generation
for system calls. Supports Linux, Mac OS X, NetBSD and OpenBSD.
-
Honeyd, a virtual honeynet daemon with
personality. [Honeyd Honeypot Development]
- OpenSSH - popular open source SSH implementation.
-
Privilege Separated OpenSSH, preventing
privilege escalation.
-
libio, a
simple library that abstracts data transport into data sources
and data sinks connected via multiple filters.
-
Stegdetect,
an automated tool for detecting steganographic content in
images. This steganography detector is capable of detecting: jsteg,
jphide, and outguess 0.13b. It includes stegbreak, a tool that
launches dictionary attacks against steganographic systems and xsteg,
a graphical frontend to stegdetect.
-
Vomit, Voice Over Misconfigured Internet Telephones.
-
Crawl, A Small and Efficient HTTP crawler.
-
libevent, a
simple library for callbacks on I/O events. It includes support
for kqueue.
-
ScanSSH, a fast open proxy and SSH Version scanner.
-
OutGuess, a universal steganography program, allowing for
deniability, best image fits and more. It's core is independant
of the cover data format.
-
NetBSD, a portable UNIX-like
operating system.
Privilege Separation and Systrace are part of my effort to improve Cyber Security.
For those of us who are favored with an understanding of the German
language, two rather old writings of mine:
-
A short article I was asked to write for a magazine about the
Internet. It is written in German.
-
A seminar talk for the Physics Deparment at the University of Hamburg:
Thermodynamik und Nachhaltigkeit.
Also in German.
To keep my creative chaos in reign I also maintain some
notes, on
things I have done, want to follow up on, or think are interesting
in general. Recently, I also started Age of Ignorance to document some of the developments that lead to stifled innovation and the restriction of knowledge.
