@hakluke This happened to me twice, on the same program, both crits, one ATO and another RCE. I didn't ask for proof, but I have been paid out for other crits on the program without issue, so I just took them at their word. Looking back, maybe I should have asked for proof lol.

@nnwakelam I gave my life to Jesus in a run down parking lot almost 18 years ago. Best decision I ever made. DMs are always open if you ever wanna chat.

@infinitelogins RESOURCES

[Harley Kimball @infinitelogins]

I analyze thousands of bug bounty content items every month. Less than 5% makes it to the newsletter.

I distilled those curated selections down to the top 25 resources for 2026 and put them in this PDF. It includes the top platforms, tools, and people that consistently deliver high signal content.

Comment RESOURCES and I'll DM you the PDF for free. (Make sure your DMs are open)

I (and by I, I mean Claude lol) built a tool to easily output ffuf results, with regex, min/max, and include/exclude search features. I realize you can do this already with JQ, but it makes it easier IMO.
