Fuzzing: An introduction to Sulley Framework
Fuzzing is the art of knowing how to put heavy pressure on software in order to find security vulnerabilities. Fuzzing frameworks have been among us since many years. Some of them have made the difference and been adopted by well-known computer security researchers. This paper is an introduction to the fascinating world of fuzzing by exploring the awesome Sulley Fuzzing Framework. We also intend to demonstrate how quick and easy it could be to find security breaches and weaknesses in nowadays software.

Manipulating Memory for Fun & Profit
Memory analysis and manipulation can provide security analysts with formidable weapons. During his talk at Information Security Day for ISACA Luxembourg Chapter, Frédéric BOURLA presented most memory manipulation tricks from both offensive and defensive angles. The talk first dealt with the attacker’s layer, from pivoting attacks to IEEE1394 issues through In-Memory Fuzzing, which permits auditors to bypass built-in features, network limitations and encryption to remain able to uncover security vulnerabilities in a running application. In a second stage, the talk focused on the benefits of memory manipulation in Computer Forensics and Malware Analysis fields, especially when facing sophisticated malcode, such as kernel rootkits or heavily encrypted reverse Trojans. Basically, this talk aimed to open the doors to a fascinating world which could easily allow security analysts to save lots of time during their recurrent duties.

The Growing Hacking Threat to Websites: An Ongoing Commitment to Web Application Security
The World Wide Web is the growth engine of our decade. Because the Web has the power to make everything available to anyone, anytime, where ever they are, through which ever device, even century-old businesses are adopting Web-centric business models. Government information systems are also becoming Web-centric because they, too, realise that technology allows them to meet and exceed the expectations of citizens with lower budgets. In essence, Web applications have become vital to almost any organisation, but these applications can be dangerously weak links in the network security perimeter.
