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:
https://issues.chromium.org/issues/40062121@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.

@henry_null @rebane2001 Cue Microsoft issuing a press release accusing Rebane of "violating coordinated vulnerability best practices." They've barely had time to react, after all...
@EdCates @rebane2001 I mean its them who made it public first I guess

@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
