OpenSSF Malicious Packages via OSV
Summary
Malicious code in dsh-moss-console (npm)
Details
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.

Independent LPM AI assessment
CleanIndependent AI assessment: clean. LPM AI assessed this version as clean; the assessments disagree.
The inspected source uses system metrics and the plugin's account balance for its stated wallpaper display, with local storage and a loopback data server. Runtime downloads and wallpaper launch require explicit UI actions; the bundled elevated batch launcher has a hard-coded developer path, but no hidden install or import-time attack was found.
Static reason
No blocking static signals were detected.
Trigger
Plugin activation starts the local data service; wallpaper installation and launch require UI POST actions.
Impact
Local status and balance are displayed and cached locally; no unrelated data collection or external telemetry was identified.
Mechanism
Reads system metrics and the plugin's account balance for display, writes balance data locally, and serves live data on loopback. A user-triggered installer downloads Electron and Koffi.

Independent scan evidence
public snapshotAI called this Clean at 92.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The manifest describes a Windows wallpaper plugin that displays local system status and account balance.
- The plugin reads system metrics and the account balance for its display, then writes the balance to a local balance.json file.
- The live data server binds to 127.0.0.1:17800.
- Runtime installation is initiated by a UI action that sends a POST request; it downloads Electron and Koffi from the URLs named in the source.
- The bundled batch launcher is separate from package activation, and its source contains an explicit Start-Process -Verb RunAs command with a hard-coded developer path.
Evidence against
- The native MossWallpaper.exe is an unsupported PE binary, so its contents could not be inspected directly.
- The batch launcher uses a hard-coded developer path and requests elevation when manually launched.
