Problem overview.
The challenge this resource is designed to solve.
When a Linux device is lost, stolen, or decommissioned, IT professionals need a reliable method to securely erase all data and configurations. Manually wiping a Linux machine can be complex and time-consuming, requiring multiple steps. This script automates complete system destruction, preventing unauthorized access and ensuring compliance with security policies.
About this resource.
What it does and how it fits into your workflow.
This script is designed to completely and irreversibly erase a Linux device by:
- User & System Data Removal – Recursively deletes /home, /root, and other critical directories.
- Configuration & Credentials Erasure – Removes system settings, SSH keys, VPN credentials, and saved passwords.
- Complete Filesystem Wipe – Deletes /etc (which contains essential configurations) and /server if applicable.
- Total System Destruction – The final deletion of / will render the device completely unusable.
This script is extremely destructive and should only be used when full data removal is required.

Use cases.
Common ways to put this resource to work.
- Lost or Stolen Linux Device Protection – Prevent unauthorized access by remotely erasing a compromised machine.
- Decommissioning or Repurposing Hardware – Securely wipe a Linux system before disposal or reassignment.
- Security Incident Response – Quickly remove sensitive data from a system during a security breach.

- Automated IT Asset Management – Integrate with Level’s automation to trigger secure wipes under specific conditions.
Recommendations.
Practical guidance for a reliable rollout.
- Pair with Lost/Stolen Endpoint Automation – Automate execution when a device is flagged as missing.
- Test in a Safe Environment – Never run this script on a live production system unless data destruction is intended.
- Use with Extreme Caution – This script is irreversible and will make the device inoperable.
- Modify for Less Destructive Wipes – If only user data needs to be removed, avoid deleting /etc and /.
