Man Stole $122M from Facebook and Google by Impersonating Quanta
This is very similar to these domain renewal or the trademark renewal invoices spam letters that you get in your mail.They look very legitimate but are actual from other companies just sending you a bill for something that you don't owe.I assume many smaller companies with untrained staff pay these items without double checking and that is why these things still come int he mail.I find the "trademark renewal" ones especially devious as they come from a company called something like "US Trademark Renewal services" and the invoices look like they come from a federal agency.
