Training Hacking ipv6 Network

Fernando Gont

 

The IPv6 protocol suite was designed to accommodate the present and future growth of the Internet by providing a much larger address space than that of its IPv4 counterpart, and is expected to be the successor of the original IPv4 protocol suite. The imminent exhaustion of the IPv4 address space has resulted in the deployment of IPv6 in a number of production environments, with many other organizations planning to deploy IPv6 in the short or near term. Additionally, a number of activities

such as the World IPv6 Day in 2011 and the upcoming World IPv6 Launch Day (scheduled for June 2012) have led to an improvement in the awareness about IPv6 and an increase in the number of IPv6 deployments.There are a number of factors that make the IPv6 protocol suite interesting from a security standpoint. Firstly, being a new technology, technical personnel has much less confidence with the IPv6 protocols than with their IPv4 counterpart, and thus it is more likely that the security

implications of the protocols be overlooked when the protocols are deployed. Secondly, IPv6 implementations are much less mature than their IPv4 counterparts, and thus it is very likely that a number of vulnerabilities will be discovered in them before their robustness matches that of the existing IPv4 implementations. Thirdly, security products such as firewalls and NIDS’s (Network Intrusion Detection Systems) usually have less support for the IPv6 protocols than for their IPv4 counterparts, either in terms of features or in terms of performance. Fourthly, the security implications of IPv6 transition/co-existence technologies on existing IPv4 networks are usually overlooked, potentially enabling attackers to leverage these technologies to circumvent IPv4 security measures in unexpected ways. The imminent global deployment of IPv6 has created a global need for security professionals with expertise in the field of IPv6 security, such that the aforementioned security issues can be mitigated. While there exist a number of courses and trainings about IPv6 security, they either limit themselves to a high-level overview of IPv6 security, and/or fail to cover a number of key IPv6 technologies (such as transition/co-existence mechanisms) that are vital in all real IPv6 deployment

scenarios. Fernando Gont, a well-known IPv6 security researcher will deliver a comprehensive IPv6 hacking training covering real-world IPv6 attacks along with real-world mitigations, thus preparing the attendees for deploying the IPv6 protocols in a secure manner.

Learning Objectives

This course will provide the attendee with in-depth, hands-on, training on IPv6 security, such that the attendee is able to evaluate and mitigate the security implications of IPv6 in production environments.The attendee will be given an in-depth explanation of each topic covered in this course, and will learn how each feature of the IPv6 protocols and related technologies can be exploited for malicious

purposes. Subsequently, the attendee will be presented with a number of alternatives to mitigate each of the identified vulnerabilities.This course will require the attendees to employ a variety of security assessment tools to perform real-world IPv6 security exercises, such that the concepts and techniques learned during this course are reinforced with hands-on expertise.

Who Should Attend

Network Engineers, Network Administrators, Security Administrators, Penetration Testers, and Security Professionals in general.

Participants Are Required To

Participants are required to have a good understanding of the IPv4 protocol suite (IPv4, ICMP, etc.) and of related components (routers, firewalls, etc.). Additionally, the attendee is expected to have knowledge about basic IPv4 troubleshooting tools, such as: ping, traceroute, and network protocol analyzers (e.g., tcpdump)

Training iOS Applications Attack Defense

Sebastien Andrivet

 

Learn the secrets of the iOS platform, how to attack iOS applications and how to correctly implement secure iPhone and iPad apps.
This training starts with a short introduction about security concepts and iOS. It is then highly practical: you will learn how to take the control of your iOS device, how to intercept communications, how to reverse engineer applications and find security defects. Then in the second part of the training, you will learn how to correctly implement secure iOS applications: what are the most common security mistakes and the corresponding solutions. The training concludes with some advanced hacking techniques.

Win an iPad!
All participants will have a chance to win an iPad by participating to a small contest at the end of this training


Requirements
 No requirement, except some understanding of computers. In particular, as the training is based on exercises and applications already prepared, no previous knowledge of iOS development is necessary. This training is both for novices and experimented people. Each person will have to bring her or his own laptop under Windows, Mac OS X or Linux. If the participant wants to install the tools on her or his own laptop, Mac OS X 10.7 (Lion) is required. But as most of the training will be done in a virtual environment, it is not mandatory. We will also provide a limited number of iOS devices for participants. You can also choose to bring your own.

Training Win32 Exploit Development

Peter Van Eeckhoutte (a.k.a @corelanc0d3r)

The Corelan Live Bootcamp is a truly unique opportunity to learn both basic & advanced techniques from an experienced exploit developer. During this 3 day course, students will be able to learn all ins and outs about writing reliable exploits for the Win32 platform.  The trainer will share his “notes from the field” and various tips & tricks to become more effective at writing exploits.
We believe it is important to explain the basics of buffer overflows and exploit writing, but this is not “your average” entry level course. In fact, this is one of the finest and most advanced courses you will find on Win32 stack based exploit development.
This hardcore hands-on course will provide students with solid understanding of current Win32 (stack based) exploitation techniques and memory protection bypass techniques.  We make sure the course material is kept updated with current techniques, includes previously undocumented tricks and techniques, and details about research we performed ourselves.  Combined with the way the course is built up, this will turn these 3 days into a truly unique experience.
During the course, we not only share techniques and mechanics, but we also want to make sure you understand why a given technique is used, why something works and why something doesn’t work.
Finally, we offer you post-training support as well.   If you have taken the course and you still have questions, we will help.

Why take this course

• Are you interested in the process of turning an advisory into a working exploit ?
• Do you want to figure out if a given security patch/hotfix should be applied immediately or not ?
• Do you want to learn how to read and understand existing exploits ?
• Have you ever found yourself in a position where you have to change an existing exploit but failed to make it work.
• Do you want to write reliable exploits and integrate them into Metasploit ?
• Do you want to know how shellcode works ?
• Do you have basic knowledge about win32 exploit development already, but want to learn more about some of the more advanced topics listed below (see course overview) ?
• Did you read the Corelan exploit development tutorials, but still want to take the classes to fully understand and master the concepts ?
• Do you have other reasons to learn how to write exploits for the Win32 platform ?
• Are you willing to suffer and bleed a bit, learn fast and not intimidated by debuggers and assembly instructions…
• …then this course is what you need !

Target audience

Pentesters, auditors, network/system administrators, developers, people part of a security department, security enthusiasts, or anyone interested in exploit development.
If you have a strong desire to learn and willing to suffer & bleed, then check out the schedules & register for one of the classes.  If you are interested in organizing the course at a conference or as a private course at your company, send me an e-mail (peter[dot]ve{at}corelan[dot]be)
