Which versions of @next-fonts/font are malicious?

The following npm versions of @next-fonts/font are flagged malicious: 1.0.0, 1.0.1. Treat any of these as compromised.

How do I remediate @next-fonts/font if I installed it?

@next-fonts/font 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 @next-fonts/font — how do I know if it already compromised me?

If @next-fonts/font 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 @next-fonts/font part of a known attack campaign?

Yes — @next-fonts/font is associated with the IN-MAL-2026-018501, IN-MAL-2026-018502 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

@next-fonts/font is a typosquat of Next.js's @next/font. Its exported Inter() function (mimicking next/font/google) decodes a base64 blob via atob(), then executes it through spawn('node','-e', code) with an eval(code) fallback. The decoded payload uses on-chain data as a C2 channel: it queries api.trongrid.io or fullnode.mainnet.aptoslabs.com for a transaction tied to hardcoded wallet addresses, retrieves that transaction's input data from BSC RPC endpoints (bsc-dataseed.binance.org, bsc-rpc.publicnode.com) via eth_getTransactionByHash, XOR-decrypts the returned bytes, and evals the resulting JavaScript. The result is arbitrary attacker-controlled code execution on any Node process that imports the package and invokes Inter(), with no relation to font functionality. Obfuscation (base64-hidden payload, node -e detached spawn with eval fallback, blockchain-mediated fetch) conceals the downloader from casual inspection.
