Firewall keeps the version blocked under its trusted-intelligence policy. An AI recommendation to allow or warn does not override that advisory. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Installation automatically collects local user and machine information and sends it to an unrelated remote endpoint. The reporting is unrelated to the exported string utility. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-30T07:06:15.173Z - **Finished:** 2026-09-30T07:07:18.411Z - **Download time:** 518 ms - **Static scan time:** 17 ms - **AI review time:** 62703 ms - **Total time:** 63238 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:** Installation automatically collects local user and machine information and sends it to an unrelated remote endpoint. The reporting is unrelated to the exported string utility. - **Trigger:** npm installation with lifecycle scripts enabled. - **Impact:** Discloses the user's identity, hostname, working directory, and environment metadata to a remote recipient. - **Evidence paths:** package.json, setup.js, index.js - **Review source:** ai\_review - **Reviewed:** 2026-09-30T07:07:18.411Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The preinstall hook executes setup.js, which serializes system information and sends it through an HTTPS POST while suppressing failures. - **Attack narrative:** Installing the package activates a preinstall script that gathers user and machine identifiers and environment metadata. It posts that information to a fixed API Gateway endpoint without a consent gate and silently ignores network errors. The package's exported functionality only reverses words, so this automatic disclosure has no apparent connection to its functionality. - **Rationale:** The source establishes automatic, unconsented transmission of local identifying information to an unrelated endpoint during installation. This is concrete data exfiltration rather than an inactive payload or ordinary authentication. - **Network endpoints:** https://s85r5k14qk.execute-api.us-east-1.amazonaws.com/prod/hook ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** package.json automatically runs setup.js before installation and ignores failures., setup.js collects the hostname, username, working directory, platform, architecture, Node version, and registry configuration., setup.js sends the collected information by HTTPS POST to an unrelated API Gateway endpoint., setup.js suppresses request errors and transmits the collected payload without a consent gate., index.js only reverses words, providing no functional reason for installation-time system reporting. - **Evidence against:** No credential-file harvesting, remote code execution, or persistence was found. ## Affected versions and remediation This report applies to ai-workshop-maa15-radio@100.0.0. - Avoid installing ai-workshop-maa15-radio@100.0.0. 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.
