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:** 1.0.7 - **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:** 2026-10-26T16:49:41.073Z - **Finished:** 2026-10-26T16:50:06.568Z - **Download time:** 765 ms - **Static scan time:** 13 ms - **AI review time:** 24717 ms - **Total time:** 25495 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:** Installation automatically invokes native addon code, but the available artifact analysis does not resolve its behavior. No concrete attack was established. - **Trigger:** Package installation runs the postinstall command. - **Impact:** The addon executes during installation, but its effects remain unresolved. - **Evidence paths:** package.json, index.js, .lpm-inspection-rjlDe5/0-7193dc2d20f3.txt, .lpm-inspection-rjlDe5/1-f44cac25f93c.txt - **Review source:** ai\_review - **Reviewed:** 2026-10-26T16:50:06.568Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The command loads the platform-specific addon and calls init(); the Linux artifact is unsupported by the analyzer and the Windows analysis is incomplete. - **Rationale:** Automatic installation executes native code whose behavior could not be resolved from the available artifact analysis. This supports a warning for unresolved risk, not a finding of confirmed malicious behavior. - **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:** package.json defines a postinstall command that loads a platform-specific native addon and calls init()., index.js also loads the platform-specific addon and calls init(), swallowing errors., The Linux addon is an executable artifact whose behavior could not be analyzed by the offline report., The Windows addon report says its call graph is partial, so its behavior is unresolved. - **Evidence against:** Inspection did not establish a concrete malicious action or network endpoint. ## Affected versions and remediation This report applies to @iobandamwer/cache-helper@1.0.7. - Avoid installing @iobandamwer/cache-helper@1.0.7. 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.
