Step by step
It doesn't break into your computer. It asks you to do it, and you agree, because it looks like an ordinary security check. Here is exactly how it goes.
Why antivirus misses it
Antivirus watches for software breaking in: a bad download, a dodgy attachment, code exploiting a hole in your browser. None of that happened here. You opened a normal system window and ran a command, on purpose, because a page you trusted told you to. To your computer that is just you using your computer, so nothing objected. The theft and the install come after, from a command your machine believes you chose to run.
Where you'll meet it
These pages turn up on hacked ordinary sites, in search results, on fake download and streaming pages, and in ads. The trick works because it looks routine. Everyone has clicked "verify you are human" a hundred times without a second thought, and that is precisely the habit it borrows.
What you just watched is one version of it. The same kind of page, dressed up differently each time, is behind all of this.
Sometimes it's a fake security check. Sometimes a fake update, or a video that suddenly won't play. Sometimes the page drops the command onto your clipboard by itself, sometimes it talks you into copying it. We watch for all of it, and push new detection out to everyone, free plans included.
