the FBI just warned that search engines -- which is to say, Google -- are selling ads that impersonate crypto and finance sites in order to steal logins and install ransomware. https://www.ic3.gov/Media/Y2022/PSA221221
Google also sells ads that impersonate government agencies like the IRS, including with URLs like irs.gov-whatever.com, I reported last year.
These ads all violate Google's rules, they said, but, of course, Google still sells 'em.
