  • http-uploader-dev

A critical malware incident was identified in the npm package http-uploader-dev. According to the GitHub Advisory (GHSA-4cmw-88qw-qcpr), any computer with this package installed or running should be considered fully compromised.

The advisory recommends that all secrets and keys stored on affected computers be rotated immediately from a different, uncompromised system. While the package should be removed, the advisory notes that full control of the computer may have been given to an outside entity, meaning removal of the package alone may not eliminate all malicious software resulting from the installation.

This represents a critical supply chain attack through a malicious npm package with potential for complete system compromise.

Indicators of compromise

Packages

Remediation

  • Immediately isolate any computer with http-uploader-dev installed from the network
  • Rotate all secrets, API keys, credentials, and signing keys from a different, uncompromised computer
  • Remove the http-uploader-dev package from all systems
  • Perform a full security audit and malware scan of affected systems
  • Review system logs and network traffic for signs of unauthorized access or data exfiltration
  • Consider full system reimaging if the package was installed on production or sensitive systems
