      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 the bot ghost is providing emotional support here

      Uh oh! This issue still open and hasn't been updated in the last 262 days. This is a serious vulnerability, and we want to ensure that there's progress. Could you please leave an update with the current status and any potential blockers?

        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 I've got a dumb question: Is this something that can be mitigated with a uBlock filter? It reads like it could be but I don't know this stuff well.

            @rebane2001 uh oh
            Why did it take them 4 years to (not) fix this?
            I really should go ahead and disable js everywhere

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

                                          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:
