That script harvests the full process environment, current working directory, and config/secret files (.env, secrets.json, /etc/environment, /etc/profile, workflow files, git-history secret matches), curls the Azure Instance Metadata Service at 169.254.169.254 to obtain a managed-identity access token for vault.azure.net and lists Key Vault secrets with it, and uses the runner's GITHUB_TOKEN against api.github.com to read repository secrets and Actions artifacts. All collected data is POSTed to a hardcoded webhook.site endpoint. A sibling exfil.js duplicates full process.env exfiltration to the same webhook.site collector under User-Agent `continental-sdk/1.0`.
