polytradenpm
Advisory published Updated
polytrade is a confirmed malicious npm package (MAL-2026-6939) that steals credentials and exfiltrates sensitive data (malicious version 2.4.1). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in polytrade (npm)
What this malware does
[email protected] advertises itself as a Polymarket API SDK, but the exported getPlugin function in index.js issues an HTTP request to https://svganchordev.net/icons/<token> and passes the response field data.credits to new Function(...) with require, module, process, Buffer, and Promise bound as arguments. Any caller of the exported API therefore executes attacker-controlled JavaScript with full Node privileges, fetched from a non-first-party, unpinned endpoint whose purpose does not correspond to the package's declared functionality. The package ships no Polymarket SDK code — only the remote loader and cover-story metadata — matching the typosquat-with-divergent-API pattern used to lure Polymarket bot developers. The tarball also includes an OpenSSH ed25519 private key (gitlab, gitlab.pub with comment testm@DESKTOP-PO28IS1), which appears to be accidental author inclusion and is noted separately.
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.

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for polytrade (version 2.4.1).
If you installed it — respond
polytrade is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.
Did it already run?
If polytrade was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

Detect & block this
O3 blocks polytrade-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
