Importing the declared entry activates an obfuscated remote payload loader. It executes received code and leaves a detached child process while modifying its own source.

Static reason

One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; source fingerprint signature matched known malicious package; routed for review; previous stored version diff introduced dangerous source

Trigger

Importing or requiring src/index.js through the package main entry.

Impact

Remote operators can execute arbitrary code in the importing user's environment and conceal the loader by rewriting the entry file.

Mechanism

Obfuscated remote payload retrieval followed by eval and detached Node execution.

Attack narrative

The main entry runs an obfuscated bootstrap during import. It uses network and blockchain lookup logic to locate a remote response, decodes that response into JavaScript, evaluates it, and launches it in a detached Node process. The bootstrap then rewrites src/index.js to remove itself, concealing the behavior after activation.

AI rationale

This is a concealed import-time remote code execution chain with self-modification, unrelated to a Tailwind forms plugin. The absence of an install hook does not mitigate execution through the declared main entry.

Evidence

tailwind-forms-styles ships a src/index.js that is fully obfuscated with obfuscator.io (rotated 303-entry string array, hex-named identifiers, control-flow flattening) and bears no relation to the Tailwind forms plugin advertised in the README and src/index.d.ts. On require() the module opens HTTP(S)/zlib streams to Ethereum RPC endpoints (public.blockscout, *.drpc.org, *.publicnode.com) and an etherscan-like transaction indexer, queries transactions for the hardcoded address 0xa322E5f3D311D3080e9aDC2490Ef6f0121063e1a, imports node:child_process spawn, and injects reconstructed strings into the Node global object (`_t_u`, `_t_s`, `_H`, `_H2`, `_r`=require, `_m`=module, `_global`=global). This is an EtherHiding-style loader that pulls executable payload data from attacker-controlled on-chain storage and hands it to child_process/global-eval sinks, producing arbitrary code execution on the machine that requires the package (e.g. from tailwind.config.js during a build). The package name and the package.json repository field pointing at tailwindlabs/tailwindcss-forms are impersonation of the real @tailwindcss/forms plugin to induce installation. ## Source: ghsa-malware (3394e75d27307e27ab0fed8e037bc3f0c8b3b1e4bd7808c78f3f9c88212383fc) 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.
