LPM AI assessed this version as suspicious; the assessments disagree. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Trusted malware advisory block - **Public report status:** Published - **Threat category:** Malware - **Selected version:** 2.0.1 - **Selected version is latest:** Yes - **Analysis source:** OpenSSF/OSV Malicious Advisory (OpenSSF/OSV) OpenSSF/OSV malware advisory MAL-2026-18177 identifies this version as malicious and supplies the Firewall block. LPM AI assessed this version as suspicious; the assessments disagree. Independent AI assessment: suspicious. LPM AI assessed this version as suspicious; the assessments disagree. OpenSSF/OSV advisory MAL-2026-18177 confirms this npm version as malicious. data-pipeline-testmetest 2.0.1 is a self-spreading credential stealer that runs on \`npm install\` without an install script: its \`binding.gyp\` source \`\/dev/null 2\>&1; echo stub.c)\` makes node-gyp run \`index.js\`, an obfuscated loader that decrypts a 939 KB payload and pipes it into Bun (downloaded from GitHub if missing)... ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-22T04:57:49.563Z - **Finished:** 2026-10-22T05:00:11.015Z - **Download time:** 1266 ms - **Static scan time:** 3269 ms - **AI review time:** 136917 ms - **Total time:** 141452 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:** A native build can execute the obfuscated entrypoint, which decrypts and executes bundled code. The payload’s effects remain unresolved, so no specific theft, damage, or network attack is confirmed. - **Trigger:** A package installation or build path that processes binding.gyp with node-gyp. - **Impact:** Package-controlled hidden code executes during the build, but its actions and data access are not established by the inspected source. - **Evidence paths:** binding.gyp, index.js - **Review source:** ai\_review - **Reviewed:** 2026-10-22T05:00:11.015Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The build configuration runs node index.js; the entrypoint decodes its wrapper, decrypts embedded AES-GCM payloads, evaluates one, and runs another through Bun. - **Rationale:** The implicit build-time execution of heavily obfuscated, encrypted code presents a concrete unresolved risk. The visible Bun installer behavior is consistent with installing Bun, and the flagged locations do not establish account actions; the encrypted payload prevents a clean assessment. - **Files touched:** binding.gyp, index.js, .lpm-dependency-evidence-dc1483a2-9c81-4172-a34e-a157ccf46ddb/0/npm-linux/package.json, .lpm-dependency-evidence-dc1483a2-9c81-4172-a34e-a157ccf46ddb/0/npm-linux/install.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for AI warning decision:** package.json names index.js as the entry point, declares bun as a dependency, and has no lifecycle script., binding.gyp runs node index.js while generating a source file, creating a native build path that executes the entrypoint., index.js wraps a numeric ROT13 decoder around eval; static decoding reveals embedded AES-GCM decryption, evaluation of one decrypted result, and execution of another through Bun., The scanner-flagged Bun installer code handles temporary files and installs or downloads and links the platform Bun binary; these excerpts show file setup rather than account actions. - **Evidence against:** The package has no declared lifecycle hook. The dependency installer’s visible download is for the Bun platform binary from registry.npmjs.org, consistent with its installer behavior. ## Affected versions and remediation This report applies to data-pipeline-testmetest@2.0.1. - Avoid installing data-pipeline-testmetest@2.0.1. 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.
