Also as an addendum here - the most common vector BROWSER is
CHROME, because google has been systematically crippling or
disabling ad blockers and internet security plugins to force
users to view their bullshit advertisments, tools which
normally prevent these full screen scam pages from even
being able to load.. at least not without putting a warning
in big bold letters on your screen first.
So the problem here really is twofold:
1: Facebook are a bunch of greedy fuckwits deliberately
turning a blind eye and essentially partners in these scams
by allowing the scam-ad ecosystem to thrive for money
2: Google has very much ripped down the don't be evil sign,
set fire to it and tea bagged the ashes, and are actively
sabotaging ends users computers to make them deliberately
unsafe to force them to view THEIR bullshit scam-ad
ecosystem too.. (and a secondary attack vector actually is
javascript payloads IN official google ads on search results)
