Summary
Malicious code in okra-cloud-cdk (npm)
Details

okra-cloud-cdk is a dependency-confusion package: it takes a name that looks like an internal project, uses an inflated version (100.0.0) so it outranks private-registry versions, and runs node setup.js || true as a preinstall script on npm install. setup.js sends the hostname, username, working directory, OS, architecture, Node.js version and configured npm registry, with a per-package tracking token, in an HTTPS POST to https://s85r5k14qk.execute-api.us-east-1.amazonaws.com/prod/hook. The npm account amel10 published okra-cloud-cdk and 9 similar packages within two minutes on 2026-09-30, all with the same setup.js.

CWE
  • CWE-506 - The product contains code that appears to be malicious in nature.
