NoSuchCon a démarré violemment avec la présentation par j00ru de ses recherches sur le kernel windows. Il s’est d’abord penché sur les fonctions de gestion de la mémoire (nt!memcpy, nt!memmove…) mettant l’accent sur le fait que les copies s’effectuent dans l’ordre inverse des données.

Hack in The Box Amsterdam 2013

Keynote jour 1 : Embracing the uncertainty of advanced attacks with Big Data analytics

La keynote de lancement de la conférence avait pour thème la détection d’incidents à l’aide du Big Data. Ce terme est présent dans de nombreux milieux depuis des années mais commence à peine à être utilisé dans le monde de la sécurité.

Insomni’hack 2013 – Armory level3

This challenge was the last level on the ARM platform. It was a crackme with a stripped binary including a basic anti-debugging trick. Sadly, only one team managed to complete this challenge before the end of Insomni’hack and another wasn’t far from what we discussed later.

Insomni’hack 2013 Armory level1 & level2

Level1 should be pretty straightforward. Looking at the assenbly, you can see that it prints the current working directory by using system(“pwd”) and then strcpy user controlled data to a fixed size buffer.

Insomni’hack 2013 : Armory wargame

As arm CPU are getting more and more used, we decided to create an arm-based wargame consisting of 4 challenges.

The first one, described here, is a reverse engineering challenge that will give you the credentials to access the actual raspberry pi box.

Insomni’hack 2013 : Money money money

Money Money Money

Even after "The Event", money is still the key to beat your opponents. Our scouts found an old banking server which should contain information about the accounts and the money they contain, but this old computer used to use perforated cards. Our engineers were able to create an interface to use it on modern technology, but they are not able to break the security system to get the data.

A popular game amongst survivors is the Rock-Paper-Scissors-Lizard-Spock game. To gain their respect, we strongly encourage you to be the best at this game. This will strengthen your reputation and will attract new citizens.
