Found the error Not allowed to load local resource: file:///etc/passwd while looking at infosec.pub’s communities page. There’s a community called “ignore me” that adds a few image tags trying to steal your passwd file.
You have to be extremely poorly configured for this to work, but the red flags you see should keep you on your toes for the red flags you don’t.
Yeah this is a TIL for me. I didn’t realize they were separated out. It makes sense, though I grant I’ve never taken a close look at these files.
