- top vulnerable web server is nginx 1.8.0 followed by IIS 7.5
- vulnerabilities (mostly phishing) not limited to porn or other sites with questionable content; use of foreign content (ads, cdns) main vector for phishing attacks (who would've thought?)
- recommends to always use ad blockers; also recommends to use HTML subresource integrity feature to web developers
While most points aren't surprising, I'd expected nginx to have a better security record.
