- marginalia_nu 3y agoInternet-scale web crawlers are hard to hide. You can just set up a bunch of domains, and flag any IPs that repeatedly visit them as likely crawlers; then serve malicious content to the rest.
- saalweachter 3y agoTry going to the URL directly, and try curling the URL with a referrer of Google. There's a thing that's been happening the last year or two where compromised web servers serve the intended content unless there's a referrer of Google (and maybe Bing?). The site looks normal to the owner, or to crawlers, but when a user clicks through from Google it redirects them to a spam site. I mostly see it with restaurants getting hijacked by herbal quackery.
