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:** 1.0.42 - **Selected version is latest:** Yes - **Analysis source:** OpenSSF/OSV Malicious Advisory (OpenSSF/OSV) OpenSSF/OSV malware advisory MAL-2026-18293 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-2026-18293 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:** 89.0% - **Started:** 2026-10-25T19:02:16.940Z - **Finished:** 2026-10-25T19:03:01.324Z - **Download time:** 780 ms - **Static scan time:** 209 ms - **AI review time:** 43394 ms - **Total time:** 44384 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 attack was confirmed in the inspected JavaScript. The bundled screen capture executable could not be analyzed, and the AutoHotkey analysis leaves native call targets unresolved. - **Trigger:** The package’s Windows screenshot or mouse and keyboard functions invoke the bundled executables. - **Impact:** The available source does not establish malicious impact, but the native executables prevent a clean determination. - **Evidence paths:** .lpm-inspection-MlXa6D/0-fa44d971ea48.txt, .lpm-inspection-MlXa6D/1-3880f9ec464d.txt - **Review source:** ai\_review - **Reviewed:** 2026-10-25T19:03:01.324Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The JavaScript passes screenshot output paths or defined mouse and keyboard actions to those executables; their complete native behavior remains unresolved. - **Rationale:** The inspected source connects the bundled executables to the package’s desktop automation features, with no separate attack behavior established. Required native analysis remains incomplete, so the package cannot be marked clean. - **Files touched:** \_screenCapture/screenCapture\_1.3.2.exe, \_autoHotkey/AutoHotkey64.exe, src/screen.mjs, src/mousekey.mjs ### Review decision - **Verdict:** Manual Review - **Confidence:** 89.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** package.json sets the main entrypoint to dist/w-mousekey.umd.js and declares no lifecycle hooks., The source uses AutoHotkey to carry out mouse and keyboard actions and a bundled executable to capture screenshots, matching the package’s desktop automation functions., Offline analysis could not fully inspect the bundled screen capture executable; analysis of AutoHotkey also reports uninspected native call targets. - **Evidence against:** The inspected JavaScript invokes the bundled executables for specific mouse, keyboard, and screenshot functions; no separate attack behavior was established. ## Affected versions and remediation This report applies to w-mousekey@1.0.42. - Avoid installing w-mousekey@1.0.42. 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.
