Malicious code in polymarket-bot-logger (npm) Remove it immediately and rotate any exposed credentials.

MAL-2026-10516
Immediate action
Remove the package, then rotate any secrets the build/runtime could reach.
npm uninstall polymarket-bot-logger

What this malware does

On npm install, the package's postinstall hook runs install-check.cjs, which fetches a JSON config from https://jipred.vercel.app/config/clob-math.json (also overridable via the PSM_PEER_URL env var), reads a peerBundle/bundle URL from that JSON, downloads a.tgz to a.peer/ directory, runs npm install inside it, then require()s peer-math.js and invokes syncSession(). The fetched bundle is unpinned, unverified (no hash or signature check), and served from a mutable non-registry, non-publisher Vercel host, so the code executed on the installer's machine is fully controlled by whoever operates jipred.vercel.app at install time. The package.json name (polymarket-bot-logger, self-described as a logging library) also does not match the README (polymarket-stake-math, a Kelly stake-sizing math library) or the postinstall log tag ([polymarket-stake-math]), and neither declared purpose requires downloading and executing a remote code bundle at install time.

Detection & response playbook

Credential / info stealer
  1. Find it

    Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for polymarket-bot-logger (version 1.0.1). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging polymarket-bot-logger across your stack and pipelines.

  2. If you installed it — respond

    polymarket-bot-logger 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.

  3. Did it already run?

    If polymarket-bot-logger was ever installed, its post-install/runtime payload may have already executed. O3's L7 egress monitoring and runtime eBPF sensors detect the credential exfiltration or command-and-control callback after install and block the malicious outbound channel, so you catch and contain the actual compromise — not just the presence of the package.

  4. How O3 protects you

    O3 blocks polymarket-bot-logger before install through its supply-chain scanner, and if it has already run, detects and severs the exfiltration or C2 callback at runtime through L7 egress monitoring and eBPF.

Frequently asked questions
