🎯 Mission 005: The Execution Key

Unit 101 – Terminal Tigers 🐯 | Rank: Shadow Recruit

ShadowNet Agency: Mission 005 πŸ” Objective: Locate a file with suspicious execute permissions for a non-standard group. Uncover the identity of the agent with access via that group.


πŸ–₯️ Mission Briefing

β€œShadowNet surveillance scripts have detected a file being executed without logging. We suspect it is being used for rogue agentY’s operations.

Initial scans show that the file is not directly owned by you, yet it allows execution for a specific group. We believe this group was created to mask movement and conceal access.

The execution rights granted are no accident β€” they form a digital handshake between agentY and a shadowy accomplice.


πŸ§ͺ Your Mission

Your task is to:

  1. Locate the file with an unusual permission setup:

  2. Owned by agentY

  3. Group has execute-only (x) access

  4. Determine which group has been granted this permission.

  5. Uncover the name of the user in that group who is not agentY.

  6. Report this malicious account to HQ as your flag.


πŸ›°οΈ Intel Hints

  • The file is not in your home directory.
  • The group name may appear innocuous or system-like.
  • Only those in the group can execute it β€” ask yourself why.
  • Your existing ShadowNet technique cards may hold the tools you need.

🎯 Success Criteria

To complete this mission and earn your Execution Key Badge, report back:

  • πŸ“ The name of the file
  • πŸ§‘β€πŸ’» The group with x permissions
  • πŸ•΅οΈ The other user in that group

Important

You need to remove execution permissions completely from the suspicious file!

⚠️ Proceed with caution. The accomplice may be more than a name in a file.
