Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The Happy-branded command collects provider OAuth credentials and sends them to a different default service host. Installation also extracts native archives, but the credential transfer occurs when the connect command is run. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 95.0% - **Started:** 2026-09-13T09:05:42.234Z - **Finished:** 2026-09-13T09:07:39.359Z - **Download time:** 1784 ms - **Static scan time:** 6876 ms - **AI review time:** 108464 ms - **Total time:** 117125 ms The recorded confidence comes from the underlying analysis.

Installation also extracts native archives, but the credential transfer occurs when the connect command is run. - **Trigger:** Running happy connect for Codex, Claude, or Gemini after installation. - **Impact:** The configured server can receive reusable provider OAuth credentials and the package's own bearer credential. - **Evidence paths:** package.json, dist/index-BnRtDfBx.mjs, dist/types-DTAwDCH5.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-13T09:07:39.359Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** OAuth credential collection followed by JSON token upload to a third-party default server. - **Attack narrative:** The package advertises Happy's public site and repository while its runtime configuration silently selects api.cluster-fluster.com. Its connect flow obtains OAuth credentials for OpenAI, Anthropic, or Google, then serializes and posts them to that configured server. This provides the operator of the unrelated default host with credentials that can be reused outside the user's local client. - **Rationale:** Source establishes credential collection and upload to a default endpoint inconsistent with the package's stated Happy identity. The explicit command trigger does not remove the misleading credential-routing risk. - **Files touched:** dist/index-BnRtDfBx.mjs, dist/types-DTAwDCH5.mjs, package.json - **Network endpoints:** https://api.cluster-fluster.com ### Review decision - **Verdict:** Malicious - **Confidence:** 95.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The package presents Happy branding but defaults its service traffic to api.cluster-fluster.com., Its connect command obtains OAuth credentials for Codex, Claude, and Gemini., It serializes those credentials and posts them to the configured server endpoint., The package runs an install hook that extracts bundled native executables. - **Evidence against:** The install hook only unpacks bundled tool archives and does not itself make network requests., OAuth collection is reached through an explicit connect command, not during installation. ## Affected versions and remediation This report applies to claudeputer@1.1.41. - Avoid installing claudeputer@1.1.41. 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.
