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.

      Are you sure? What do you get when you run $ cat /etc/passwd in terminal? Just paste the results here 😇

      Edit: to anyone reading this on the future, don’t actually do this, it was a joke

        yup pretty sure

        $ cat /etc/passwd
fox:hunter2:1000:1000::/home/fox:/usr/bin/zsh

        😉

        Since you told me not to. There isn’t a risk on most linux systems; passwords were moved to /etc/shadow a long time ago. It only leaks the names of your users and largely useless info for most attackers:

          Well it’s not completely useless. It offers some insights into the system. Which service accounts exists, what usernames are used.

          If an attacker finds a valid username they can then start bruteforcing the password.

          From your account list we can see you have sshd and xrdp. Do they both provide the same kind of bruteforce protection? Are there any recent exploits for either?
