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. Source: amazon-inspector (84a86d5a0d96567fc1ab65c8f61ab1610b8488859dd53ade8a7a05a86389d371) [email protected] ships a `preinstall` lifecycle script (`setup.js`) that runs automatically on `npm install`. The script collects installer-side identifiers — hostname (`os.hostname()`), username (`os.userInfo().username`), current working directory (`process.cwd()`), platform, architecture, Node version, and the configured npm registry URL (`npm_config_registry`) — and POSTs them along with a hardcoded token to a hardcoded AWS API Gateway endpoint at https://s85r5k14qk.execute-api.us-east-1.amazonaws.com/prod/hook. The package's declared main is a trivial `zeroPad` stub whose functionality (`Pad number with leading zeros`) is unrelated to the package name `okra-cloud-cdk`, and the implausibly high version number (100.0.0) is consistent with an attempt to win resolution against an internal package of the same name. The exfiltrated `npm_config_registry` value in particular discloses internal/private registry hostnames, which are the identifying signal used to select follow-up dependency-confusion targets.
