given the information now available, it probably got packaged with chrome, ie, firefox, opera (english), safari, et aliae after delivery of notice from your not so secret anymore government courts and goon squads. they could have built it into windows, os?, and ubuntu system files using the same wetware vulnerability. those notices that aren’t allowed public discussion are very much a security threat to the global economy.
they couldn’t keep up, so they had to “cheat”.
