Yeah, I do @musllibc, FOSS & infosec stuff. But now is not the time for a mostly-/only-tech Twitter feed.

      Equifax ran code for *years* that executed s/w from abandoned domains, including a malware server since last Fall. https://www.wsj.com/articles/equifaxs-latest-security-foil-a-defunct-web-service-1507937742 …pic.twitter.com/nYZXozTjZR

      Browsers: deprecate non-same-origin scripts and make a plan for transitioning to removal of support for them.

      Important to note that in this case, the calling code was *on* Equifax's server. Literally, a web service expired in 2014.

      But it was loading some resource (likely script) from the abandoned domain. This is what I'm saying should be disallowed.

      ah, I see. Yep. That would be the nuclear option, but also kill most web fonts

      There's utterly no reason to be using scripts, much less non-same-origin, for fonts. It's cargo cult nonsense.

      But if you did need them just host copies locally under your own control.

          preaching to the choir. Always chuckle when a dev can't render a local web page on laptop in flight b/c jquery, google fonts etc

          I am but a humble sysadmin, new to a dev team, and I kind of wondered about that... you just gave me the courage to speak up about it

          often an issue of devs w/ just enough knowledge to be dangerous; if scale-up needed, use CDN for *all* static assets.

          Thanks - depending on the answer I get for why we're pulling that stuff, I'll suggest we look into that instead

          if you really wanna have some fun, load the site from inside something like malwr & watch the realtime network calls.
