How to respond if you find a VMware ESXi 9 license key on GitHub
- Remove the key from the repo — but do not rely on a normal commit to fully erase it.
- Purge history: use git filter-repo or BFG Repo-Cleaner to remove the secret from history, then force-push and inform collaborators.
- Rotate the license: contact VMware or your license administrator to revoke/replace the key.
- Inspect related commits and metadata for other exposed secrets or personal data.
- Notify affected parties and follow your incident response playbook.
