Included in this section will be defining your goals for what kind of impact you wish to achieve, identifying areas of interest, and perseverance (also known as going down the rabbit hole).

From there, we’ll dive into a demo of the bug. This will include a working PoC for CVE-2020-13379, an exploitation kit that will assist in full exploitation, and a summary of some useful escalation techniques. We will also discuss what it looks like to use this bug against companies who host Grafana instances in the DMZ or in the internal network.

To bring it all around, we’ll talk about the experience of reporting this bug to different vendors and mass-exploitation across bug bounty programs. This will include some lessons learned from mass-exploitation, some awesome collaboration with very skilled hackers, and some great interactions with programs.
