Summary
Malicious code in google-cloud-secret-manager-config-poc (npm)
Details

Malicious npm package published by the microsop threat actor as part of a dependency-confusion campaign that impersonates internal tooling at Microsoft, Google Cloud, and PayPal using inflated semver values (e.g. 99.9.x, 100.1.x) to win npm resolution against private internal packages. All packages in the campaign falsely advertise themselves as "Security Research PoC" and execute on preinstall via node index.js, exfiltrating to disposable webhook.site endpoints.

This package targets Google-Cloud-flavored internal naming and performs SSH key validation/fingerprinting on the build host. On install it checks for /root/.ssh/id_rsa, runs ssh-keygen -l -f to extract the key fingerprint and ssh-keygen -y -f to derive the public key, then POSTs {hostname, fingerprint, public_key, key_exists} to https://webhook.site/813b99f6-c86c-4a1f-9318-518a3c153992 tagged status: KEY_VALIDATION_RESULT. The captured fingerprint and public key let the operator correlate the install host against authorized-keys lists for downstream lateral movement.
