Maybe this will be helpful to you or to someone else. All the slides and other videos in the bug_crowd_university series (and the level-up videos) are located in this Github repo. github.com/bugcrowd/bugcrowd_university/ I find it a lot easier to navigate to each video or pdf than to chase down the videos through youtube. As to Hackvertor, this add-on is located inside your Burpsuite program. Go to the Extender tab, then Bapp store tab - All of the add-ons are located there. Some of the add-ons are limited to the Pro version, but Hackvertor works with the community addition.

@Course_test thats why i asked videos to learn using burpsuite and other tools i know what is sql injection, xss .... What's wrong with this guys which part of my question you didn't understand

@Course_test 1)i said I never tryed it i didn't say i want to directly do it (get bounty) 2) of course i searched on internet and i found some videos and tutorials i just asked for more (good one )so if you have something to share then do it otherwise move on ,i don't know why you feel like you have to respond to my comment
