Learning new things

Mass assignment and learning new things Hi everyone, For this second article on BugBountyHunter we’re going to talk about a vulnerability and how I did to learn more about it. Indeed, among the questions I am most often asked is “but how do you learn a new vulnerability, find resources, etc…” This is a difficult question to answer because there are many different learning methods and each one is suitable for a different type of person.

My methodology during Firstblood

My methodology during Firstblood Hello everyone From the 9th to the 16th of May the first live event of BugBountyHunter took place, namely Firstblood. Of course I participated. For this first event I was in collaboration with my bugbounty mate Serizao, but I greatly thank’s all hunters I exchanged with during the event. I strongly believe that collaboration is the key, and the proof is that this is a team that finished on the podium.

My bounty infrastructure

My bounty infrastructure with Docker [31/12/2020] : Updated the post for Rengine to v0.5 and a clearer / cleaner configuration of Traefik as well as the removal of Portainer. After some problems with Rengine for certificate management and a new service that I want to use, I switched to a full docker infrastructure on my server, apart from the use of a few containers it’s my first experience with Docker but after some difficulties I find it rather practical and modular.
