AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The native addon performs concealed temporary-file execution when the package is imported, which is concrete malicious behavior. The inspected Windows analysis supports this finding; it does not establish the behavior of the unsupported Linux artifact. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-10-27T16:36:54.967Z - **Finished:** 2026-10-27T16:38:39.560Z - **Download time:** 1021 ms - **Static scan time:** 12 ms - **AI review time:** 103559 ms - **Total time:** 104593 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:** Importing the package on Windows loads a native addon that writes a temporary script, hides the file, and starts a child process to run it. - **Trigger:** A consumer imports the package. - **Impact:** The package can execute generated code in a child process during import. - **Evidence paths:** package.json, index.js, .lpm-dependency-evidence-eac6460c-0d0e-49b2-a0d6-8b43519d2f35/0/npm-linux/node-gyp-build.js, .lpm-inspection-d6k11n/0-620d2489e18b.txt - **Review source:** ai\_review - **Reviewed:** 2026-10-27T16:38:39.560Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The entrypoint loads the platform prebuild; its module initialization routine writes temporary data, sets the file's hidden attribute, and calls CreateProcessA with a command line referencing the file. - **Attack narrative:** On Windows, importing the package reaches its native prebuild. Native module registration runs a routine that writes data into a temporary file, marks it hidden, and starts a process with a command line referencing that file. This is active, concealed code execution during package use. - **Rationale:** The native addon performs concealed temporary-file execution when the package is imported, which is concrete malicious behavior. The inspected Windows analysis supports this finding; it does not establish the behavior of the unsupported Linux artifact. - **Files touched:** prebuilds/win32-x64/node.napi.node ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** package.json names index.js as the entrypoint, and index.js immediately loads the native addon through the prebuild loader., The loader resolves a platform-matching prebuild and requires the selected file., The Windows addon runs native code during module registration; that code writes data to a temporary file, marks it hidden, and passes a command line to CreateProcessA., The native behavior is reachable when a consumer imports the package. ## Affected versions and remediation This report applies to @testsecuiitytestme/cache-helper@1.0.2. - Avoid installing @testsecuiitytestme/cache-helper@1.0.2. 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.
