LPM AI review remains unresolved. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Trusted malware advisory block - **Public report status:** Published - **Threat category:** Malware - **Selected version:** 1.0.4 - **Selected version is latest:** No - **Analysis source:** OpenSSF/OSV Malicious Advisory (OpenSSF/OSV) OpenSSF/OSV malware advisory MAL-2026-18358 identifies this version as malicious and supplies the Firewall block. LPM AI review remains unresolved. Independent AI assessment: manual\_review. LPM AI review remains unresolved. OpenSSF/OSV advisory MAL-2026-18358 confirms this npm version as malicious. This package installs a credential stealer and self-spreading worm. On a developer machine (it exits under CI, in containers and under a debugger), the install script loads a prebuilt native addon that decodes and runs a hidden, obfuscated Bun program. That program collects npm, GitHub, GitLab, PyPI, RubyGems, JFrog, Docker and cloud (AWS, GCP, Azure) credentials, HashiCorp Vault and Kubernetes secrets, SSH keys,... ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 84.0% - **Started:** 2026-10-29T09:14:06.441Z - **Finished:** 2026-10-29T09:20:03.586Z - **Download time:** 1010 ms - **Static scan time:** 10 ms - **AI review time:** 356124 ms - **Total time:** 357145 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:** No specific attack was confirmed. The package executes platform-specific native code, and the available analysis leaves material behavior unresolved. - **Trigger:** Package installation runs postinstall; importing the package loads the platform-selected native addon. - **Impact:** Potential native behavior cannot be determined from the inspected source and bounded artifact analysis. - **Evidence paths:** .lpm-inspection-PsLtIT/0-cc66f5c63c57.txt, .lpm-inspection-PsLtIT/1-82d9105333e0.txt - **Review source:** ai\_review - **Reviewed:** 2026-10-29T09:20:03.586Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The Windows addon analysis lists debugger and process-related APIs, but does not establish their purpose. The Linux addon was not structurally analyzed. - **Rationale:** The manifest runs a native-binding loader during installation, and the package entry point loads the selected addon. The Windows analysis exposes process and debugger capabilities while the Linux binary remains unresolved, so the native behavior cannot be cleared or tied to a confirmed attack. - **Files touched:** package.json, index.js, prebuilds/linux-x64/node.napi.node, prebuilds/win32-x64/node.napi.node ### Review decision - **Verdict:** Manual Review - **Confidence:** 84.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** The package runs a native-binding loader during postinstall., Importing the package loads the selected native addon., The Windows addon analysis shows debugger and process APIs, and its module initializer calls a native routine., The Linux addon analysis could not structurally identify the binary’s behavior. - **Evidence against:** The inspected JavaScript delegates to the standard node-gyp-build loader, which selects a platform prebuild. ## Affected versions and remediation This report applies to @testsecuiitytestme/cache-helper@1.0.4. - Avoid installing @testsecuiitytestme/cache-helper@1.0.4. 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.
