LPM AI assessed this version as suspicious; the assessments disagree. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Trusted malware advisory block - **Public report status:** Published - **Threat category:** Malware - **Selected version:** 1.1.1 - **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 assessed this version as suspicious; the assessments disagree. Independent AI assessment: suspicious. LPM AI assessed this version as suspicious; the assessments disagree. 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:** 76.0% - **Started:** 2026-10-26T16:49:11.853Z - **Finished:** 2026-10-26T16:50:06.568Z - **Download time:** 1272 ms - **Static scan time:** 13 ms - **AI review time:** 53430 ms - **Total time:** 54715 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 was established. Automatically invoked native initialization remains unresolved, and the Windows analysis exposes process and file capabilities without resolving their use. - **Trigger:** Package installation or importing index.js. - **Impact:** Unknown native actions could occur during installation or import; no specific harmful effect or network destination was verified. - **Evidence paths:** package.json, index.js, .lpm-inspection-7O88TF/0-e62a0ab569c2.txt, .lpm-inspection-7O88TF/1-83a11170272a.txt - **Review source:** ai\_review - **Reviewed:** 2026-10-26T16:50:06.568Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Both paths call init on the platform-specific native addon; the Linux binary is unclassified, and the Windows initializer’s behavior is not established by the bounded analysis. - **Rationale:** The manifest and entrypoint both invoke opaque native code automatically, and the Linux artifact remains uninspected. The available Windows analysis shows potentially sensitive capabilities but does not prove malicious behavior, so this warrants a warning rather than a block. - **Files touched:** package.json, index.js, addon.node, addon\_win.node ### Review decision - **Verdict:** Suspicious - **Confidence:** 76.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for AI warning decision:** The postinstall hook selects a platform-specific native addon and calls its init function., The JavaScript entrypoint also selects the native addon and calls init when imported., The Linux addon is an ELF binary whose behavior the offline analysis could not inspect., The Windows analysis lists process, debugger, temporary-path, and file APIs, but does not establish what the initializer does with them. ## Affected versions and remediation This report applies to @iobandamwer/cache-helper@1.1.1. - Avoid installing @iobandamwer/cache-helper@1.1.1. 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.
