Blockchain Decentralized Application Hacking Course - A Journey Into Smart Contract Hacking And DApp Penetration Testing (Web 3.0)


Smart Contract Exploitation and Hacking Course Announcement


What Is this: 

For those who have been hitting me up on twitter and YouTube for more blockchain smart contract exploitation content this blog is for you. I have posted a video below explaining what this is and included a course outline of the content we are providing free for everyone. I was actually told recently that I am crazy for giving out this level of detailed content and training for free.. However, I believe in the original hacker ethic code from long ago, that information should be freely available for everyone!! In this frame of mind, the only pay for content will be if you wish to go the extra mile. For the person who wants to prove to themselves or others that they learned something via a certification package with detailed exam prep targets and guides, followed by a final exam CTF and reporting write-up. 

So I hope you enjoy this content. The content and walk through labs will be all free. This content will be posted regularly over the next few months 90% of it is already written and ready to go.

We will start off with the differences between Solidity and other languages and do a quick coding overview before we start hacking. This way everyone is on the same page when we start looking at coding examples of vulnerable targets or reviewing case study code. Then we will cover a wide range of typical issues that effect decentralized applications(DApps) and smart contracts on the Ethereum blockchain. How to spot them and exploit them with full walk-through style learning. Subjects we have already released (Re-Entrancy, Integer Attacks, Authorization) have been updated with new code, new examples, and case studies etc. Some of the learning content will be the same but with a lot of newly added content.  And in the case of Authorization completely re-written and expanded on. 

Basically this course was created to get the information out there in a clear concise way. Because when I started researching blockchain hacking all I found was a paragraph here and there on something that was overly technical or completely theoretical. I couldn't find any clear concise learning or examples. This drove me nuts trying to figure everything out, until I gave up and just coded my own vulnerabilities and hacked them. So hopefully this fills the knowledge gap to offer a clear and concise, Zero Fluff resource to those on the same path. 


CTF Exam: 

If you do enjoy this series over the next few months and want to challenge your skills and certify that you learned something we will be also offering pay for certification bundle that includes Decentralized Application (DApp) targets and detailed lab guides as preparation for a final exam against a more comprehensive CTF certification challenge target. More info on this as the months progress. 


Bug Bounty of Sorts: 

These labs are completed but we are working on a way to deliver the content which requires me to code up a course delivery software. So feel free to hack the course delivery software once its up, if you break in or bypass authorizations I will give you the full course for free provided you help me fix it. :P 


Pre- Requisites: 

This is more of a intermediate / advanced course with a white box code approach to bug hunting and a dynamic approach to application hacking and exploiting targets, with that said you will need the following pre-requisites: 

  • Ability to code in some language and understanding of coding concepts. 
  • Application hacking or development background with firm understanding of vulnerabilities


Contact Info:

As this is free, I only ask that you provide constructive feedback as we are creating other more advanced hacking courses on random subjects we are interested in. Most of which will be free.  And feedback helps us not do things which are not useful and integrate new ideas where they make sense.

Cheers and I hope this finds you well.
