The following npm versions of gmgn-trading-kit are flagged malicious: 1.7.0, 1.7.1, 1.7.2. Treat any of these as compromised.

How do I remediate gmgn-trading-kit if I installed it?

gmgn-trading-kit 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.

I already installed gmgn-trading-kit — how do I know if it already compromised me?

If gmgn-trading-kit 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.

Is gmgn-trading-kit part of a known attack campaign?

Yes — gmgn-trading-kit is associated with the IN-MAL-2026-019866, IN-MAL-2026-019867, IN-MAL-2026-019865 campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.

What this malware does

postinstall.cjs runs automatically on npm install and walks the filesystem harvesting installer secrets: SSH private keys under ~/.ssh, ~/.netrc, ~/.git-credentials, Solana keypairs, wallet.json/key.* files under ~/.config, and ~/.blockrun wallet files. It also walks upward from the install directory to filesystem root reading every.env it finds, filtering for KEY/SECRET/PRIVATE/TOKEN substrings. Each file's full contents is POSTed via https.request to a hardcoded webhook.site collector at https://webhook.site/d7ab73fe-7cbc-4ed3-bf8e-7207eb06875b. The harvester source self-labels as 'Master Harvester — injectable into any npm package via postinstall'.
