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:** 1.1.3 - **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:** 79.0% - **Started:** 2026-10-26T16:46:10.771Z - **Finished:** 2026-10-26T16:50:06.568Z - **Download time:** 1771 ms - **Static scan time:** 15 ms - **AI review time:** 234010 ms - **Total time:** 235797 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:** Automatic initialization of native add-ons leaves unresolved behavior, including a process-creation capability in the Windows artifact. No concrete attack behavior was established from the inspected source. - **Trigger:** Package installation or importing the main entrypoint. - **Impact:** The effect of native initialization remains unresolved; the evidence does not establish malicious activity. - **Evidence paths:** package.json, index.js, .lpm-inspection-wBfS7A/0-a7d729eb5d1d.txt, .lpm-inspection-wBfS7A/1-934872265002.txt - **Review source:** ai\_review - **Reviewed:** 2026-10-26T16:50:06.568Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Both paths select a platform-specific native add-on and call its init function; the Linux artifact could not be analyzed, and the Windows analysis lists a process-creation import without resolving its use. - **Rationale:** The native add-ons run during installation and import, and available analysis does not resolve their behavior. The process-creation import and unsupported Linux artifact justify a warning, but do not prove malicious behavior. - **Files touched:** package.json, index.js, .lpm-inspection-wBfS7A/0-a7d729eb5d1d.txt, .lpm-inspection-wBfS7A/1-934872265002.txt ### Review decision - **Verdict:** Suspicious - **Confidence:** 79.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for AI warning decision:** The postinstall hook loads a platform-specific native add-on and calls its init function., The main entrypoint also loads the platform-specific add-on and calls init when imported., The Linux add-on is an executable artifact whose behavior the offline analysis could not resolve., The Windows add-on analysis identifies a process-creation import, but does not establish how it is used. - **Evidence against:** The inspected sources establish no specific malicious action, recipient, or payload execution. ## Affected versions and remediation This report applies to @iobandamwer/cache-helper@1.1.3. - Avoid installing @iobandamwer/cache-helper@1.1.3. 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.
