ROOTS 2018: Library and Function Identification by Optimized Pattern Matching on Compressed Databases – Maximilian von Tschirschnitz

Sanna/ January 7, 2019/ ROOTS

[Editor’s note: This article belongs to the Reversing and Offensive-oriented Trends Symposium 2018 (ROOTS). It was misplaced, so we publish it today. Maximilian’s talk was recorded and can be watched on Vimeo.] The goal of library and function identification is to find the original library and function to a given machine-code snippet. These snippets commonly arise from penetration tests attacking a remote executable, static malware analysis or from an IP infringement investigation. While there are several tools designed to achieve this task, all of these seem to rely on varied methods of signature-based identification. In this work, the author argues that this approach is not sufficient for many cases and propose a design and implementation for a multitool called KISS. KISS uses lossless compression and highly optimized pattern matching algorithms to create a very

DeepSec 2018 Training: Malware Analysis Intro – Christian Wojner

Sanna/ September 28, 2018/ Conference, Security, Training

With malware (malicious software) featuring crypto-trojans (ransomware), banking-trojans, information- and credential-stealers, bot-nets of various specifications, and, last but not least, industry- or even state-driven cyber espionage, the analysis of this kind of software ıs becoming more and more important these days. With a naturally strong focus on Microsoft Windows based systems this entertaining first-contact workshop introduces you to one of the most demanding but nonetheless compelling fields in IT-Security. We asked Christian a few more questions about his talk. Please tell us the main facts about your training. This training is for every IT (Security) person who wants/needs to have their first encounter with the stunning field of malware analysis. On the basis of an especially designed, exciting scenario blended with various technical detours packed into a 6-stages workshop, students will… learn how easy
