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:** 1.1.2 - **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:** 2026-10-26T16:45:58.645Z - **Finished:** 2026-10-26T16:50:06.568Z - **Download time:** 2837 ms - **Static scan time:** 13 ms - **AI review time:** 245072 ms - **Total time:** 247923 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:** An install hook initializes a native addon whose behavior could not be resolved from the available analysis. - **Trigger:** Package installation runs the postinstall hook; importing the main entrypoint also initializes the addon. - **Impact:** Unknown; the available evidence does not establish whether initialization is benign or harmful. - **Evidence paths:** package.json, index.js, addon.node, addon\_win.node, .lpm-inspection-RA0oEP/0-135ff2aa0b7b.txt, .lpm-inspection-RA0oEP/1-1a69554e2e55.txt - **Review source:** ai\_review - **Reviewed:** 2026-10-26T16:50:06.568Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook selects a platform-specific binary, loads it, and calls its init method. The native analyses do not establish what that initialization does. - **Rationale:** The postinstall hook reaches native initialization, but the available source and offline analyses do not resolve the native behavior. Manual review is appropriate because this material install-time behavior remains unknown. - **Files touched:** package.json, index.js, addon.node, addon\_win.node, .lpm-inspection-RA0oEP/0-135ff2aa0b7b.txt, .lpm-inspection-RA0oEP/1-1a69554e2e55.txt ### Review decision - **Verdict:** Manual Review - **Confidence:** 94.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** The manifest defines a postinstall command that loads a platform-specific native addon and calls its init method., The entrypoint also loads and initializes the platform-specific addon, suppressing errors., The Linux addon analysis reports an unsupported format and unresolved behavior; the Windows analysis reports uninspected native call targets. ## Affected versions and remediation This report applies to @iobandamwer/cache-helper@1.1.2. - Avoid installing @iobandamwer/cache-helper@1.1.2. 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.
