    back in 2022 i found a bug that would let me, with no user interaction, turn any chromium-based browser into a permanent js botnet member

    in edge, you wouldn't even notice anything out-of-place, and would stay connected to the c2 even after closing the browser

    today, almost 4 years later, the bug is finally public:

    @rebane2001 Clearly, @mozilla's choices around not implementing certain APIs is paying off.

      even worse, edge no longer even makes the download menu pop up, so it's completely silent js rce that keeps running even after you close the browser !!

      all from just visiting a single website once !!

                        @rebane2001 really cool work. Didn't realize this sort of bug class even existed. Hope they up the bounty; this seems worth more than $1000
