A modest comparison between two ways of storing our unstructured data, from MongoDB to Elasticsearch.

IRMA (Incident Response & Malware Analysis) is a multi-scanner framework for identifying and analyzing suspicious files. In this article, we describe, step by step, how one can contribute to this open-source project by integrating his own analyzer.

A "hands-on" introduction to LLVM passes through obfuscation.

We recently looked at the Obfuscator-LLVM project in order to test its different protections. Here are our results, and explanations on how we deal with obfuscation.

UPDATE: A way to patch the vulnerability is provided at the end of the article. We explain a vulnerability found when the Samsung Galaxy S5 was released and patched recently by Samsung. It allows a remote attacker to install an arbitrary application by using an unsecure update mechanism implemented in the UniversalMDMClient application related to the Samsung KNOX security solution. The vulnerability has been patched on the Samsung Galaxy S5 but also Note 4 and Alpha. Yet the Samsung Galaxy S4, S4 mini, Note3 and Ace 4 (and possibly others) are still vulnerable.

Quarkslab propose plusieurs stages, certains sujets pouvant aussi être aussi traités sous forme d'alternance. Ca touche à des tonnes de domaines : recherche de vuln, analyse de code, crypto, compilation, reconnaissance réseau, malware et réponse à incidents. Bref, il y en a pour tous les goûts.

Two weeks ago we proposed a Python CTF with a few tickets to HITB KUL to win. Here come the results!

If you do not like reverse engineering but still like security challenges, we built one for you. And you can use your brain to get a free entry to HITB KUL: https://conference.hitb.org/hitbsecconf2014kul/

We recently began to work on source code analysis and the main objective was to easily collaborate on a same analysis. So, we started to develop a framework based on Clang that will be described in this blog post.
