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:** 1.0.8 - **Selected version is latest:** No - **Analysis source:** OpenSSF/OSV Malicious Advisory (OpenSSF/OSV) OpenSSF/OSV malware advisory MAL-2026-18329 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-2026-18329 confirms this npm version as malicious. Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-26T16:49:34.140Z - **Finished:** 2026-10-26T16:50:06.568Z - **Download time:** 757 ms - **Static scan time:** 11 ms - **AI review time:** 31659 ms - **Total time:** 32428 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 concrete attack behavior was established. The package automatically loads native code, and the available artifact analysis does not resolve its behavior. - **Trigger:** Package installation runs the postinstall hook; importing index.js also calls the native initializer. - **Impact:** The native code's effects cannot be determined from the available analysis. - **Evidence paths:** package.json, index.js, .lpm-inspection-OG4xNf/0-17b8868b53e6.txt, .lpm-inspection-OG4xNf/1-501363507b6f.txt - **Review source:** ai\_review - **Reviewed:** 2026-10-26T16:50:06.568Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The JavaScript loads a platform-specific native module and invokes init(). - **Rationale:** The install hook and runtime entrypoint both activate native code. Its behavior remains materially unresolved: one artifact is unsupported and the other has uninspected call targets, so malicious behavior is not established. - **Files touched:** package.json, index.js, addon.node, addon\_win.node ### Review decision - **Verdict:** Manual Review - **Confidence:** 94.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** package.json runs a native initializer from a postinstall hook., index.js also loads the platform-specific native module and calls init()., The Linux native artifact has no supported executable analysis, so its behavior remains unresolved., The Windows artifact analysis leaves call targets uninspected and lists process and debugger APIs., The Windows analysis includes cache-path and environment-name candidates, but does not establish their use. ## Affected versions and remediation This report applies to @iobandamwer/cache-helper@1.0.8. - Avoid installing @iobandamwer/cache-helper@1.0.8. 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.
