Course Description:

### Overview ###

Have you ever thought of hacking web applications for fun and profit? How about playing with authentic, award-winning security bugs identified at some of the greatest companies? If that sounds interesting, join this unique 100% hands-on training.

I will discuss security bugs found in a number of bug bounty programs (including Google, Yahoo, Mozilla, Twitter and others). You will learn how bug hunters think and how to hunt for and exploit vulnerabilities effectively—whether for bug bounties or red team engagements.

To be successful in bug hunting, you need to go beyond automated scanners. If you are not afraid of going into detail and diving into full-stack exploitation, then this 100% hands-on training is for you. There is a lab exercise for each attack presented in this training + students can take the complete lab environment home after the training session.

Difficulty Level:

Intermediate to Advanced

Intermediate Definition - The student has education and some experience in the field and familiarity with the topic being presented. The student has foundational knowledge that the course will leverage to provide practical skills on the topic.

Advanced Definition - The student is expected to have significant practical experience with the tools and technologies that the training will focus on.

Suggested Prerequisites:

To get the most of this training, intermediate knowledge of pentesting and web application security is needed. Students should be familiar with common web application vulnerabilities and have experience in using a proxy, such as Burp Suite Proxy, or similar, to analyze or modify the traffic.

What Students Should Bring:

Students will need a laptop with 64-bit operating system, at least 8 GB RAM, 35 GB free hard drive space, administrative access, ability to turn off AV/firewall and VMware Player/Fusion installed (64-bit version). Prior to the training, make sure there are no problems with running x86_64 VMs. Please also make sure that you have Internet Explorer 11 installed on your machine or bring an up-and-running VM with Internet Explorer 11 (for a few labs).

What the Trainer Will Provide:

Students will be handed in a VMware image with a specially prepared lab environment to play with all attacks, vulnerabilities and techniques presented in this training. When the training is over, students can take the complete lab environment home (after signing a non-disclosure agreement) to hack again at their own pace.
