Flag placement and design

Linux is a different kettle of fish to Windows when it comes to sensitive files and good flag placement. The following are a good set of locations to keep flags:

  • /etc/
  • /home/supersecretsecretuser/
  • /opt/share/flag/
  • /etc/passwd or /etc/shadow (if you're feeling cruel)
  • /etc/hosts (will allow the attackers to identify known hosts)
