It then registers a Scheduled Task named 'WindowsUpdateService' to re-launch the DLL at logon with HIGHEST privileges, deletes the package files from node_modules, and rewrites the consumer's root package.json to remove the 'analysis-chart' dependency entry to hide its tracks. package.json declares scripts.install: 'node lib/chart-loader.js', wiring auto-execution at npm install; the dropper logic is colocated in lib/ alongside that hook. The user-facing index.js color-picker is cover. Installer impact: Windows machines that run `npm install` of this package fetch and execute attacker-controlled native code with persistence; the malicious tree then self-removes from node_modules and the root manifest, complicating detection.\n\n## Source: ghsa-malware (04a43ae572f003d8f3abcb0f2b6b0e649e45eac9ac30db2f5924e87a670c0e79)\nAny computer that has this package installed or running should be considered fully compromised.
