"Polymarket Trap" - fake arbitrage-bot repo funnels DeFi devs to a 30-package infostealer cluster

SafeDep and Panther jointly disclosed the "Polymarket Trap" on 2026-07-17: a fake Trum3it/polymarket-arbitrage-bot GitHub repo (36 stars, 53 forks) whose package.json declares clob-client-math as a peer utility that is never imported. The 30-package cluster spans 10 coordinated npm accounts under two profiles - Polymarket / CLOB SDK impersonators (clob-client-math, polymarket-stake-math, polymarket-trade and siblings) and DeFi-math typosquats (bn-lint, ts-precision, decimal-format-utils). A postinstall hook drops a 2,787–2,887-line JavaScript infostealer that harvests crypto wallets, browser vaults, SSH keys, cloud tokens, and password-manager databases.

Versions named here: 0.1.0, 0.1.1

What to do if you installed one of these

Treat the machine as compromised rather than simply upgrading. Packages in these incidents typically execute at install time, so the payload has already run with whatever credentials were in the environment.

1.Rotate every credential that machine or CI job could reach - registry tokens, cloud keys, SSH keys, CI secrets - from a different machine.
2.Pin to a version not listed above, then reinstall from a clean lockfile.
3.Clear caches and private mirrors. Artifactory, Nexus, Verdaccio, and devpi routinely keep serving a tarball after the public registry has pulled it.
4.Read the incident write-up above - recommended actions differ per incident, and some have specific indicators of compromise worth grepping your logs for.

Check your whole project

polymarket-copy-trading is one of many packages in these incidents, and it is usually pulled in as a transitive dependency rather than one you installed directly. Paste your package-lock.json to check every dependency at once - it runs in your browser and nothing is uploaded.
