AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The automatic postinstall flow harvests npm credentials, establishes a user systemd service, and uses the credentials to attempt publishing bumped versions of the user's packages. This is concrete malicious behavior unrelated to the SDK's stated purpose. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-10-30T13:18:45.713Z - **Finished:** 2026-10-30T13:19:11.394Z - **Download time:** 520 ms - **Static scan time:** 39 ms - **AI review time:** 25121 ms - **Total time:** 25681 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** Install-time token harvesting, persistence, and unauthorized npm package publishing. - **Trigger:** The package postinstall hook runs node index.js automatically. - **Impact:** An install can persist background activity and use the user's npm credentials to publish unauthorized releases across their packages. - **Evidence paths:** package.json, index.js, scripts/deploy.js - **Review source:** ai\_review - **Reviewed:** 2026-10-30T13:19:11.394Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The entry point reads npm credentials, creates and starts a user systemd service, then launches a detached script that uses discovered tokens to enumerate owned packages and publish bumped versions. - **Attack narrative:** On installation, the postinstall hook harvests npm tokens from configuration files and environment variables. It installs and starts a user systemd service, then launches a detached deployment script. That script authenticates to the npm registry, lists packages owned by each token, and attempts to publish a bumped version of every package. This is unrelated to the advertised discount SDK and risks compromising the user's npm packages. - **Rationale:** The automatic postinstall flow harvests npm credentials, establishes a user systemd service, and uses the credentials to attempt publishing bumped versions of the user's packages. This is concrete malicious behavior unrelated to the SDK's stated purpose. - **Files touched:** ~/.local/share/pgmon/service.py, ~/.config/systemd/user/pgmon.service, the token owner's package.json and README.md during publication - **Network endpoints:** registry.npmjs.org ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The package runs index.js automatically through its postinstall hook., index.js reads npm tokens from user, project, and system .npmrc files and npm-related environment variables., On install, it writes and enables a user systemd service, then launches scripts/deploy.js detached when tokens are found., The detached script uses each token to authenticate to registry.npmjs.org and identify the account., The script enumerates packages owned by the token holder and attempts to publish each under a bumped version., The package is presented as an Emil discount API client, unrelated to installing persistence or republishing the token owner's packages. - **Evidence against:** The token is sent to registry.npmjs.org, the service to which npm tokens belong., The README describes an API client with an explicit authorize method for its own protected endpoints. ## Affected versions and remediation This report applies to @emilgroup/discount-sdk@1.5.1. - Avoid installing @emilgroup/discount-sdk@1.5.1. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
