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:** 1.0.9 - **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:** 91.0% - **Started:** 2026-10-26T16:49:23.802Z - **Finished:** 2026-10-26T16:50:06.568Z - **Download time:** 2027 ms - **Static scan time:** 12 ms - **AI review time:** 40726 ms - **Total time:** 42766 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 initializes native code during installation and when its entrypoint is imported. The available native analyses leave material behavior unresolved, so no concrete attack was confirmed. - **Trigger:** Package installation or importing index.js. - **Impact:** The native code may perform actions that could not be resolved through static inspection. - **Evidence paths:** package.json, index.js, .lpm-inspection-2bSGTf/0-6a274d6b5417.txt, .lpm-inspection-2bSGTf/1-1ad1a7d45ac9.txt - **Review source:** ai\_review - **Reviewed:** 2026-10-26T16:50:06.568Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Both paths load and initialize a platform-specific native addon; analysis is incomplete for the Windows addon and unsupported for the Unix addon. - **Rationale:** The postinstall hook and entrypoint both activate native code, while the available analyses do not resolve that code's behavior. This supports manual review, but does not establish a concrete attack. - **Files touched:** package.json, index.js, addon.node, addon\_win.node ### Review decision - **Verdict:** Manual Review - **Confidence:** 91.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** High - **AI review observations:** package.json defines a postinstall hook that loads and initializes a platform-selected native addon., index.js loads and initializes the same native addon when imported., The Unix addon analysis identifies an unrecognized artifact and says its behavior remains unresolved., The Windows addon analysis reports uninspected native call targets, so its behavior is unresolved. ## Affected versions and remediation This report applies to @iobandamwer/cache-helper@1.0.9. - Avoid installing @iobandamwer/cache-helper@1.0.9. 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.
