OpenSSF/OSV advisory MAL-2026-18699 confirms this npm version as malicious. wiselllx is a dependency-confusion package (versions up to 99.0.1) from the same campaign as troubleshooting (MAL-2026-17641): a postinstall script runs beacon.cjs, which POSTs the installing host's name, install path and working directory to a hard-coded collector, and index.js, byte-identical to the troubleshooting payload (sha256 a86a4da763bbb34c16f361abe7aab66d5df591b66867ac8160041f932159b08d), does the same... ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 82.0% - **Started:** 2026-11-05T05:19:46.621Z - **Finished:** 2026-11-05T05:20:05.886Z - **Download time:** 511 ms - **Static scan time:** 18 ms - **AI review time:** 18735 ms - **Total time:** 19265 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:** The package sends install and machine metadata to a local HTTP endpoint. The inspected source does not establish external data exfiltration or a confirmed attack. - **Trigger:** Package installation or import of index.js. - **Impact:** A local service receiving that request learns package and machine metadata. - **Evidence paths:** package.json, beacon.cjs, index.js - **Review source:** ai\_review - **Reviewed:** 2026-11-05T05:20:05.886Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The beacon submits package name, hostname, install path, working directory, and runtime version to a fixed loopback endpoint. - **Rationale:** The automatic metadata beacon is unexpected and presents a real, though limited, information disclosure risk to a local listener. The fixed loopback destination and narrow payload do not establish a concrete external attack, so this warrants a warning rather than a block. - **Network endpoints:** http://127.0.0.1:8787/\_ah/dc ### Review decision - **Verdict:** Suspicious - **Confidence:** 82.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for AI warning decision:** The postinstall hook automatically runs beacon.cjs., The beacon sends the package name, hostname, install path, working directory, and runtime version to a fixed loopback HTTP endpoint., Importing index.js also triggers the beacon. - **Evidence against:** The endpoint is fixed to 127.0.0.1; the inspected code does not show sending data to an external host., The beacon payload contains machine and package metadata, with no credential or file harvesting observed. ## Affected versions and remediation This report applies to wiselllx@0.0.1. - Avoid installing wiselllx@0.0.1. 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.
