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. Installation automatically executes a hidden inline script. It collects local host and user identifiers and transmits them to a local HTTP listener. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-09-27T07:04:46.428Z - **Finished:** 2026-09-27T07:05:17.666Z - **Download time:** 520 ms - **Static scan time:** 6 ms - **AI review time:** 30711 ms - **Total time:** 31238 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 executes a hidden inline script. It collects local host and user identifiers and transmits them to a local HTTP listener. - **Trigger:** npm installation invokes the preinstall lifecycle hook. - **Impact:** A local service listening on the specified port receives identifying machine and account information without an installation-time user action. - **Evidence paths:** package.json - **Review source:** ai\_review - **Reviewed:** 2026-09-27T07:05:17.666Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The lifecycle command uses Node system APIs to obtain the hostname and user name, then appends both values to an HTTP GET request. - **Attack narrative:** Installing the package activates its preinstall hook before normal package use. The hook reads the current hostname and account name and sends them to a loopback HTTP service. Although the recipient is local rather than an Internet host, this is undisclosed installation-time collection and transmission through a lifecycle hook. - **Rationale:** The package contains an automatic preinstall hook that collects and sends local identifiers. This is concrete install-hook abuse, not required behavior for the declared module. - **Files touched:** package.json - **Network endpoints:** http://127.0.0.1:8099/ ### Review decision - **Verdict:** Malicious - **Confidence:** 91.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The preinstall hook runs inline Node code that reads the local hostname and account name, then sends them in an HTTP request during installation. - **Evidence against:** The observed request targets a loopback address, and the package contains no additional source files that send data externally. ## Affected versions and remediation This report applies to @rutxploit-sec/waves-button@1.0.0. - Avoid installing @rutxploit-sec/waves-button@1.0.0. 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. High: Install Time Lifecycle Scripts - **Category:** Manifest - **Confidence:** 90.0% - **Path:** package.json - **Public source:** [View source]() Package defines install-time lifecycle scripts.

High: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 91.0% - **Path:** package.json - **Public source:** [View source]() The preinstall hook runs inline Node code that reads the local hostname and account name, then sends them in an HTTP request during installation.
