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:** 1.0.41 - **Selected version is latest:** No - **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:** 90.0% - **Started:** 2026-10-25T19:02:13.678Z - **Finished:** 2026-10-25T19:02:54.652Z - **Download time:** 4043 ms - **Static scan time:** 207 ms - **AI review time:** 36723 ms - **Total time:** 40974 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 established from the inspected JavaScript. Required native executables remain materially unresolved, so their behavior cannot be cleared. - **Trigger:** The screenshot executable is launched when the Windows screenshot helper is called; the AutoHotkey setup executable is launched by its installer command. - **Impact:** The unresolved native behavior prevents a clean determination; no specific harmful effect was verified. - **Evidence paths:** \_screenCapture/screenCapture\_1.3.2.exe, \_autoHotkey/AutoHotkey64.exe, .lpm-inspection-bZhwnQ/1-3880f9ec464d.txt - **Review source:** ai\_review - **Reviewed:** 2026-10-25T19:02:54.652Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The screenshot helper runs a bundled executable and reads its output. Available analysis of the AutoHotkey executable leaves native call targets uninspected, and the screenshot executable could not be analyzed in the supported format. - **Rationale:** The inspected package code exposes screenshot and mouse/keyboard functions, with no install hook in the manifest. Required native artifacts remain unsupported or only partially analyzed, so a clean verdict is not justified; no independent attack evidence supports a warning or block. - **Files touched:** \_screenCapture/screenCapture\_1.3.2.exe, \_autoHotkey/AutoHotkey64.exe ### Review decision - **Verdict:** Manual Review - **Confidence:** 90.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** The manifest points to the runtime bundle and declares no install lifecycle hook., The Windows screenshot helper launches the package's screen capture executable and reads its output; screenshot APIs call that helper., The AutoHotkey executable's offline analysis is incomplete and reports uninspected native call targets., The screenshot executable is a required native artifact whose behavior could not be inspected in the available analysis. - **Evidence against:** The package manifest shows test and deploy scripts but no install hook., The screenshot helper is reached through the package's screenshot API, and the screenshot dependency selects platform-specific implementations. ## Affected versions and remediation This report applies to w-mousekey@1.0.41. - Avoid installing w-mousekey@1.0.41. 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.
