Malicious code in polymarket-apis (npm)
--- _-= Per source details.

Its exported `getPlugin` function fetches JSON from https://svganchordev.net/icons/<token> and passes the response's `credits` field to the JavaScript `Function` constructor, executing the returned bytes with full Node context (require, module, exports, process, Buffer, __dirname). The remote URL is assembled from split string constants (`protocol`+`separator`+`domain`+`path`) and the surrounding code is framed as a benign icon/CDN helper (`IconProvider`, `bearrtoken: 'logo'`) to disguise the eval. Because the fetched content is attacker-controlled and mutable, any caller invocation of the exported API runs arbitrary code on the installer with Node privileges. Declared runtime dependencies (`@primno/dpapi`, `node-machine-id`, `better-sqlite3`) are consistent with Windows credential and browser-data stealer payloads that the remote code can load. Package keywords (`react`, `helper`, `svg`) are inconsistent with the advertised Polymarket SDK purpose, confirming the cover-story framing. ## Source: ghsa-malware (0cf3a190eff680afcf1cf8d5519bc3b46b32bd58fe5fe2b183a0f91bcfbc84d6) 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.
AI Analysis
Technical Summary
The polymarket-apis npm package (version 1.1.0) is a malicious package impersonating the Polymarket brand. Its exported getPlugin function dynamically fetches JSON data from a remote attacker-controlled URL and executes the 'credits' field content via the JavaScript Function constructor, granting arbitrary code execution in the Node.js environment. The remote URL is constructed from split string constants to evade detection, and the surrounding code is framed as a benign icon provider to disguise the malicious eval. Declared dependencies align with known Windows credential and browser data stealers, indicating the payload's intent. This package does not provide any legitimate Polymarket API functionality and is designed to execute attacker-controlled code on any system that installs or invokes it.
Potential Impact
Users installing or running polymarket-apis version 1.1.0 risk arbitrary code execution with full Node.js privileges, which can lead to credential theft, data exfiltration, and system compromise. The malicious code is remotely controlled and mutable, allowing attackers to change payloads dynamically. The presence of dependencies associated with credential and browser data theft further increases the risk of sensitive information compromise.
Mitigation Recommendations
No official patch or remediation is currently available. Users should immediately avoid installing or using polymarket-apis version 1.1.0. Remove the package from any projects and audit systems for potential compromise if it was installed. Use trusted sources and verify package authenticity before installation. Monitor vendor advisories or npm security announcements for updates or removal of the malicious package.
