I published a blogpost on the OSDFIR Blog that is written mostly from fellow team members.
In the post I explain how to set up a Timesketch development leveraging Docker.
Have fun reading it and stay tuned for future posts around Timesketch or other related topics.

For whatever reason I today decided to change my github username from
deralexxx
to
To match some other profiles I use that username. It seems easy to do, but be careful, it also breaks stuff.
If you also want to do that, have a look at: https://help.github.com/en/github/setting-up-and-managing-your-github-user-account/changing-your-github-username
Plus I would recommend afterwards to register your old username with a different mail address to protect from people trying to claim repository links you previously owned.
Timesketch, the open-source timeline collaboration tool recently upgraded the UI and that is why I am writing a new blog post to show the new UI by processing a E01 image via plaso.
First, install plaso and timesketch (in my case I used both via docker images as it is the easiest way to get it running.
As a scenario, I am using the image file provided by NIST. Which has been covered in many many blog posts already.
First, run the plaso docker container where the image file is stored.
docker run -v /evidence/:/data log2timeline/plaso log2timeline /data/evidences.plaso /data/4DellLatitudeCPi.E01
That will run for a while.
plaso - log2timeline version 20191203

Use pinfo to inspect warnings in more detail.MD5 (evidences.plaso) = 82ed76c50a6152a8c96cd959ad494b53
For this sample, I used the dev version of docker according to https://github.com/google/timesketch/tree/master/docker/development
docker-compose up -d
export CONTAINER_ID="$(sudo docker container list -f name=development_timesketch -q)"
Create a case via Web UI
I decided to upload the plaso file via Web-UI.
Also in the Web UI, process feedback is visible
Now data is being indexed
This will trigger an entry in the debug output

After indexing, the data is ready to be explored via Timesketch
One of the new cool features is Analyzers. These analyzers run predefined queries on the data of a timeline do some actions like
To showcase the power of Timesketch, let’s try to solve some of the questions of NIST that came along with the image
This is rather easy as plaso already has a parser for that, so searching for „Windows NT*CurrentVersion“ will do the job
Again, plaso is already parsing that, searching for „timezone“ will show „ActiveTimeBias: 300 Bias: 360 DaylightBias: -60 DaylightName: Central Daylight Time StandardBias: 0 StandardName: Central Standard Time„
Seit ich vor ca. 1,5 Jahren mein Surly Orge gekauft habe, störte mich im Grunde nur eine Sache: der fehlende Fahrradständer. An vielen Orten ist es ohne Probleme machbar, das Rad anzulehnen, aber eben nicht überall.
Irgendwann bin ich dann auf dieses Video von Craig Meyer auf Youtube gestoßen:
Dort listet er folgende Dinge auf, die man benötigt:
Die Montage an sich dauert dann keine 30 Minuten, ich habe nicht mal das Hinterrad ausgebaut und trotz Scheibenbremse mit etwas Fingerspitzengefühl machbar.
Und so sieht das Ergebnis aus:
Einzige Herausforderung ist noch die Gelenkschale für einen Thule Chariot, die jetzt so angebracht ist, dass sie wohl nicht nutzbar ist. To be continued…
So day 1, I arrived around 11 AM and got myself in a queue which was surprisingly well organised and fast-moving. There is even a page to show waiting times for the last few years.
Once passing the entry area I was a little overwhelmed, lights, people, noise everywhere and the space seems simply large…
At some assembly, I met a good friend and long-time CCC / C-Base hang around who introduced me to some people and within a blink, 3 hours of conversation were gone.
Along the way, I learnt stuff about Freifunk, open firmware, and many more, but the most important thing – very good conversations and friendly people.
An aspect that is not covered much in blog posts or wikis is food. I was not sure how to prepare for the long days in regards to food and drinks. Turns out there are a lot of bars serving Mate (of course), beer, cola and other stuff and there are a lot of food places, so no a problem there (not vouching for the quality…)
Hacker Jeopardy was something I was curious but watched back in the hotel.
Pretty early, for congress standards I guess, hit the CCL around 11 AM and most floors and assemblies were empty, which had its own vibe.
Some people I wanted to meet during the congress I tried to meet today and was quite successful with.
By accident, I ran into a pitch of „| age“ a tool „a simple file encryption tool & format“, which looked quite cool and will try to play with it at a later point.

For many years I wanted to go to a CCC and this year because of different reasons I was finally able to go, this blog post is going to cover my planning and following posts will hopefully follow.
There is a log of coverage already how to prepare for a congress. Obviously, you need a ticket. I got my ticket thanks to a co-worker who is a pretty active member of a local chaos group, so was fairly easy (thx stean)
So after getting a ticket, a place to stay needs to be found. In most cases, I run with AirBnB, this time I was unable to find a cosy place nearby so I ended up doing a hotel reservation and I hope this was a good choice.
And last but not least, transportation. The way to go here for me is using german railway services, Deutsche Bahn. There is even a special page from Deutsche Bahn to get a special ticket for a lower price.
Of course, going to a conference you need your basic stuff as for every conference/travel, so I will not go into that too much. Especially for the congress, I tagged most of my gear that I plan to bring to the venue with my twitter handle and my domain so that it is easy to find the owner.
In addition to my normal list I packed the following items:
A water bottle, because @c3himmel asked for it:
A reusable water bottle.
— 36C3 Heaven (@c3himmel) December 17, 2019
There will be water dispensers on #36C3 again, so please bring a bottle to minimize use of one-way plastic bottles. Of course you can also reuse a normal plastic bottle.
Please also note that tap water is drinkable in Germany (and usually tastes good).
The tech also needs some extra time, in particular, updating every service/application running is critical. As I do not trust the wifi (as with any other wifi) VPN and a backup VPN was tested/updated.
To be able to work on stuff I also freed up some space on the devices, just in case.
Power up batteries, external power supplies and co. I do not want to run out of power.
Auch wenn ich leider nicht am Triathlon in Maxdorf teilnehmen konnte (irgendwann schaffe ich es mal an die Startlinie) haben wir das perfekte Wetter genutzt für einen kleinen Ausflug an die Radstrecke dieses top organisierten Wettkampfes, ich habe die Kamera ausgepackt und wir haben gute zwei Stunden die Radler angefeuert.
Aus eigener Erfahrung weiß ich, wie positiv selbst einzelne Anfeuerungen am Rand helfen. Und auch richtig cool wieviele Athleten sich für den Zuspruch bedankt und mit uns gelacht haben.
Da ich mir nicht sicher bin, ob es einen Foto Service gab, bzw, ich mit den Fotos nichts verdienen will, habe ich einfach alle ohne Aussortieren hochgeladen.
Die Bilder dürfen zur eigenen Verwendung unter CC-BY-SA genutzt werden unter der Nennung von Alexander Jäger als Fotograf und über einen Link hier her freue ich mich immer.
Viel Spaß mit den Fotos:

A friend of mine pitched the idea to start a blog series titled „API of the month“ based on my GitHub repository https://github.com/deralexxx/security-apis.
The idea of that series is to cover an API each month, provide some samples, talk about potential target audience and use cases for the API.
The first API to be covered is apility. The service is marketed as „Minimal and Simple Anti-Abuse API for Everyone.“ and the web page starts with a Google-like search mask.
The API documentation is pretty comprehensive and available via web page: https://apility.io/apidocs/. The documentation also gives nice curl examples for every API endpoint that can be copy-pasted.
The API itself is free but is limited in regards to API calls that can be done. pricing options are available on https://apility.io/pricing/
As an example I tried to get ratings for IPs / domains for a recent APT OSINT report.
To get started you need to sign up and verify your account via an email that you receive shortly after signing up.
I took the tweet from the malwrhunterteam: https://twitter.com/malwrhunterteam/status/1126894905668849664 to test my scripts and also the famous trafficconverter(.)biz
Especially the trafficconverter domain was listed by the tool:
{„response“: {„domain“: {„blacklist“: [„ISC-DOMAINS-LOW“, „ISC-DOMAINS-MEDIUM“], „blacklist_mx“: [], „blacklist_ns“: [], „mx“: [], „ns“: [], „score“: -1}, „ip“: {„address“: „38.102.150.28“, „blacklist“: [], „is_quarantined“: false, „score“: 0}, „source_ip“: {„address“: „“, „blacklist“: [], „is_quarantined“: false, „score“: 0}, „score“: -1}, „type“: „baddomain“}
The scripts I used are available on github:
import requests
from configparser import ConfigParser
config = ConfigParser()
config.read("config.cfg")
APIKEy = config.get('API', 'APIKEY')
print(APIKEy)
url = "https://api.apility.net/baddomain/"
headers = {
'accept': "application/json",
'x-auth-token': APIKEy
}
f = open('./input.txt', 'r')
for line in f.readlines():
print("Will investigate "+line)
response = requests.request("GET", url+line, headers=headers, verify=False)
print(response.text)
print("finished")
It should be noted that there is also a python package available at https://github.com/Apilityio/python-cli and can be installed (but I have not tested it) via:
pip install apilityio-clior
easy_install apilityio-cliThe target audience for the API as well as the service is:
Cyber security is a global issue but most people interested in the topic are not able to visit the big conferences because they are expensive or because they are not allowed to travel to the destinations.
But thanks to the evolving technology of video hosting sites and the fact that capturing talks on video is more and more getting the new norm, a lot of good security talks can be watched online.
Looking for good videos, I ended up in either a total mess of crappy videos or pretty good videos where not pushed up on the result pages by video hosting platforms because low number of views (most security talks at the moment to not attract that much audience). This is when I started a new repository called: „awesome security videos„
The idea is simple, collect and curate a list of online videos that is good from a content and a presentation point of view.
Because it is on github, I hope for others to contribute ideas, I will also have a close look on twitter, so feel free to send me a DM to https://twitter.com/alexanderjaeger
Also all videos will be added to a public youtube list: https://www.youtube.com/playlist?list=PLbE0nb-0VwXRB7kjFLlc-RBc4ihCkcP-A
