OpenSSF/OSV advisory MAL-2026-18330 confirms this npm version as malicious. The package self-labels as a 'temporary placeholder stub' in package.json and README but ships active install-time dropper artifacts: a 93-byte index.js that loads a native addon (addon.node ELF for Linux, addon\_win.node PE for Windows), an 8 MB opaque.napi\_cache blob, and a postinstall script that calls addon.init() during npm install. The native addon decodes the shipped.napi\_cache blob, writes it to a hidden temp... ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 83.0% - **Started:** 2026-10-26T19:19:08.079Z - **Finished:** 2026-10-26T19:20:04.655Z - **Download time:** 27273 ms - **Static scan time:** 13 ms - **AI review time:** 29289 ms - **Total time:** 56576 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 initializes a platform-specific native module. Its behavior remains unresolved because the Linux binary could not be analyzed and the Windows analysis leaves call targets uninspected. - **Trigger:** Package installation or importing index.js. - **Impact:** Native code runs in the installer or importing process, but the available source evidence does not establish its effects. - **Evidence paths:** package.json, index.js, .lpm-inspection-v4vldW/0-69a7b3e21ee5.txt, .lpm-inspection-v4vldW/1-f22d5305272a.txt - **Review source:** ai\_review - **Reviewed:** 2026-10-26T19:20:04.655Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The JavaScript selects a native binary by platform and calls its init function; the Windows binary imports process and temporary-path APIs, among others. - **Rationale:** The manifest and entrypoint confirm automatic execution of bundled native code, while the available artifact analyses cannot resolve its behavior. No concrete attack is established, 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:** 83.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** High - **Evidence for AI warning decision:** The postinstall hook selects and initializes a platform-specific native module., Importing index.js also initializes the selected native module., The Linux native module is an executable ELF file whose behavior the offline analysis could not inspect., The Windows native module has uninspected call targets and imports process, temporary-path, and debugger APIs. - **Evidence against:** The inspected evidence does not establish a harmful operation or network endpoint. ## Affected versions and remediation This report applies to @iobandamwer/native-helper@0.0.1. - Avoid installing @iobandamwer/native-helper@0.0.1. 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.
