Backfischfest Blog 2018

Backfischfest Blog

In den letzten Jahren hat sich der Backfischfest Blog oder auch Backfischfest Vlog um die Band Die Döftels zu einer Institution in Worms entwickelt.

Die witzige Art die Tradition auf die Schippe zu nehmen und hinter die Kulisse zu schauen macht Freude und ist jeden Tag auf dem Festplatz oder der Fischerwääd Gesprächsthema.

Aus dem Backfischfestblog sind auch solche Geschichten wie die „Terrence-Hill-Brücke“ entstanden.

Unterstützt wird der Backfischfest Blog von einigen Wormser Unternehmen. Schnitt und Kamera übernehmen rawk und Steven Amendt

fatal error: ‚fuzzy.h‘ file not found

Trying to install pydeep on OSX and getting the error below:

pydeep.c:2:10: fatal error: 'fuzzy.h' file not found
1 error generated.
error: command '/usr/bin/clang' failed with exit status 1

So far I have not found a solution for it.

Some people recommended to use:

xcode-select --install

Which did not help my issues.

Also the following:

$ export LDFLAGS="-L/usr/local/lib"
$ export C_INCLUDE_PATH=/usr/local/include

Did not help

Still searching for a solution and will update that blogpost once I found anything

9TageTicket 10 Jahre

Dieses Jahr zum Backfichfest Worms feiert das 9TageTicket, an dem ich mit einigen Freunden beteiligt bin das 10-jährige Jubiläum.
Was anfangs noch ein Scherz unter Freunden war um zu zeigen, wie oft man auf dem Backfischfest war, hat sich mittlerweile zu einer Institution entwickelt, die von Wormsern wie auch den Schaustellern gerne angenommen wird.

Die Arbeit an dem Ticket macht jedes Jahr wieder Spaß, es ist zu einer Tradition geworden, am Tag vor der Eröffnung gemeinsam die Tickets zu drucken und zu schneiden und dann den ersten Abend auf dem Fischfest gemeinsam an der Ausgabe zu sitzen, bekannte Gesichter sehen und einfach die Zeit genießen, die auch manchmal etwas stressig ist.

Ich freue mich auf jeden Fall wieder drauf.


Virtualbox OSX freeze

From time to time, esp. after starting a few virtual systems at the same time, the whole OSX system can freeze and there is basically nothing to rescue the system but cold reboot.

This is due to some limits set to low, which can be fixed by:

sudo sysctl -w kern.aiomax=512 kern.aioprocmax=128 kern.aiothreads=16

That will be effective till reboot, it can be made persistent by adding the following line to /etc/sysctl.conf


Found at

gpg: signing failed ioctl

While signing PGP keys the following error occured:

gpg: signing failed: Unpassender IOCTL (I/O-Control) für das Gerät

Which is german so googling for the following words:

gpg: signing failed ioctl

Revealed a possible solution that actually worked:

export GPG_TTY

Timed out while waiting for the machine to boot. This means that
Vagrant was unable to communicate with the guest machine within
the configured ("config.vm.boot_timeout" value) time period.

If you look above, you should be able to see the error(s) that
Vagrant had when attempting to connect to the machine. These errors
are usually good hints as to what may be wrong.

If you're using a custom box, make sure that networking is properly
working and you're able to connect to the machine. It is a common
problem that networking isn't setup properly in these boxes.
Verify that authentication configurations are also setup properly,
as well.

If the box appears to be booting properly, you may want to increase
the timeout ("config.vm.boot_timeout") value.

vagrant destroy

Upgrade Virtualbox and do the vagrant up again

Security API collection

While working on different stuff I was searching for a collection of APIs that are related of useful for security researchers, incident response people or threat intel.

Unable to find a good list of REST APIs decided to start it. The collection is hosted on a Security API list, and pull requests or issues mentioning missing APIs are highly welcome.

Why did I produce such a list? More and more people want to automate their workflows, Security Orchestration is the new Buzzword after last years Threat Intelligence, but basically containing the same, they both have in common to facilitate already available data, with Orchestration not storing that much data but enriching dots collected.

However the challenge is, what to integrate, everyone has their „go to“ tools they use on a daily base risking to miss some golden nuggets that are handy.

The list is divided (at the moment) in tools that are mostly on prem., online tools, SIEMs and various. With an increasing number of APIs that ordering might change of course.

So I really hope the list is useful and people can use it and that it can grow.

9Tageticket again a success

One day to go till the Backfischfest in Worms is starting and we can say, the 9TageTicket this year is again a big success. With more then 650 tickets pre ordered, we are on almost the same level as last year, showing that there is a constant interest in the free tickets that show other visitors the commitment to the Backfischfest.

For the first time we will have flyer for the showman explaining the idea behind 9TageTicket.
