Title
QMON: Uncomplicated monitoring for small environments
Conference
EuroTcl 2015
Date
21.6.2015
Abstract
QMON is a simple open source monitoring application suitable for a small number of hosts and services. It aims to be a quick and secure alternative to nagios with focus on simplicity. After a brief architectural overview the talk covers implementation details of CGI and CLI frontends, database backend and the actual monitoring check execution. Also, in order to provide a usable configuration interface, qmon introduces an enhanced version of ini-style configuration featuring template substitution.

Title
The state of PHP configuration and hardening
Conference
IPC2014
Date
27.10.2014
Abstract
Can there be anything wrong with empty PHP files? And what happens, if an attacker were to modify .htaccess? During development of the PHP Secure Configuration Checker (PCC) some rarely used INI directives came to mind. This session will explore the possibility of attacking web applications by PHP misconfiguration. The second part will show, that the PHP hardening extension Suhosin is very much alive. We will have the opportunity to discuss recent development and future plans.

BeF's Yate Cookbook
Read
https://bef.github.io/yate-cookbook/
Date
2014
Abstract
This document is a collection of practical solutions and ideas - recipes - related to the Yate telephony engine. Recipes give specific solutions to specific problems encountered in real life. Some recipes were derived from practical experience during the 29th and 30th Chaos Communication Congress in Hamburg, Germany. Other solutions were encountered while setting up and maintaining our public VoIP provider EPVPN (Eventphone Virtual Phone Network). The technical minded person may find a jump start into Yate or use it as a reference guide.

Abstract
Warum hat der Anwalt eines Onkels aus Süd-Afrika plötzlich Geld für mich aus der Erbschaft des Vaters seines Schwippschwagers? Warum singen betrunkene Python-Programmierer Lieder von Dosenfleisch? Diese und weitere Fragen werden mit Elan gestellt. Die in Teilen literarisch tiefgründige Auseinandersetzung mit ungewollten Botschaften zeigt sowohl die Historie, als auch mögliche Zukuftsszenarien.

Title
Stefan Esser / Ben Fuhrmannek - Security Problems in Web Applications except Injection Vulnerabilities
Date
26.1.2011
Location
Ruhr-Uni-Bochum
Abstract
Neue Sicherheitsprobleme in Web-Applikationen werden tagtäglich aufgedeckt. In der Regel handelt es sich dabei um Standardprobleme wie Injektionverwundbarkeiten oder aber die Anfälligkeit für CSRF. Zwischen all diesen Problemen schlummern jedoch meist noch viel gefährlichere Sicherheitslücken in Applikationen die auf logischen Fehlern, schlechten Zufallszahlen, schwacher Verschlüsselung oder unüberlegten Sicherheitsfixes beruhen. In diesem Vortrag werden einige solcher Lücken die im letzten Jahr in bekannten (und weniger bekannten) Applikationen aufgedeckt wurden, exemplarisch vorgestellt.

PAPER
Title
Virtual Meta-Scripting
Subtitle
Bytecode for PHP and JavaScript
Author
Ben Fuhrmannek
Date
31.5.2010
Abstract
Both PHP and JavaScript are frequently being targeted for exploiting web applications. This article elaborates on the idea of building a set of virtual machines on top of each programming language. As a result a single type of bytecode can be executed by both VMs. Particular emphasis is put on designing virtual machines to be most suitable for code obfuscation in a post exploitation scenario.
