The exported `getPlugin` function issues an HTTPS request to https://svganchordev.net/icons/111, reads the response's `credits` field, and passes it to `new Function('require','module',...,data.credits)` — executing attacker-controlled JavaScript inside the consumer's Node.js process with `require`, `process`, and `Buffer` available. Because the loader is passed `require`, subsequent stages can pull in native modules (dpapi, better-sqlite3, node-machine-id) to run a credential/wallet stealer. The URL is assembled piecewise (`protocol + separator + domain + path`) and surrounded by unused constants referencing legitimate CDNs (cloudflare, fastly, akamai, cloudfront, gcorelabs, cdnjs) and Font Awesome-style paths so the fetch reads as icon retrieval; an unused `setDefaultModule` referencing those CDNs is dead-code decoy. The package name and description impersonate the real @polymarket/clob-client to attract Polymarket integrators. Any consumer that imports the package and invokes the default export runs whatever JavaScript the operator of svganchordev.net serves at that moment.\n\n## Source: ghsa-malware (bd3cc3b2775e2ba28bb5fff5c7671fad59d10810e05e72c2f5c0c8b176c1ca8c)\nAny computer that has this package installed or running should be considered fully compromised.
