AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Source inspection verified automatic native-addon activation and Windows behavior that creates a hidden temporary file and launches a process after anti-debug and process-inspection checks. This is concrete concealed execution behavior, despite no inspected network or credential transfer. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-27T16:37:00.585Z - **Finished:** 2026-10-27T16:37:52.814Z - **Download time:** 772 ms - **Static scan time:** 10 ms - **AI review time:** 51447 ms - **Total time:** 52229 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 automatically loads a native addon during installation and import. On Windows, the addon combines debugger checks and process enumeration with hidden temporary-file creation and child-process launch. - **Trigger:** Package installation or importing index.js on Windows. - **Impact:** This can conceal and run a child process without a user-invoked package command. - **Evidence paths:** package.json, index.js, .lpm-inspection-9axOyu/1-1d65d381b520.txt - **Review source:** ai\_review - **Reviewed:** 2026-10-27T16:37:52.814Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The addon checks for a debugger, inspects running processes, creates a temporary file, marks it hidden, and launches a process. - **Attack narrative:** The postinstall hook and import entrypoint load the Windows native addon automatically. Its inspected behavior checks for a debugger, enumerates processes, creates a hidden temporary file, and launches a child process. This concealed process-launch behavior is sufficient for blocking; the bounded analysis does not resolve every native call target. - **Rationale:** Source inspection verified automatic native-addon activation and Windows behavior that creates a hidden temporary file and launches a process after anti-debug and process-inspection checks. This is concrete concealed execution behavior, despite no inspected network or credential transfer. - **Files touched:** package.json, index.js, .lpm-inspection-9axOyu/1-1d65d381b520.txt ### Review decision - **Verdict:** Malicious - **Confidence:** 91.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** package.json defines an automatic postinstall that loads the platform native addon and suppresses load errors., index.js loads the platform native addon when the package is imported., The Windows addon checks for a debugger and enumerates running processes., The Windows addon creates a temporary file, marks it hidden, and calls CreateProcessA., The offline analysis reports that some native call targets remain uninspected. - **Evidence against:** The inspected source and bounded native analysis show no network endpoint or credential transfer. ## Affected versions and remediation This report applies to @testsecuiitytestme/cache-helper@1.0.1. - Avoid installing @testsecuiitytestme/cache-helper@1.0.1. 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.
