## Security analysis

### Published attack-surface review

- **Summary:** Importing the main Tailwind plugin executes an obfuscated remote payload loader. It retrieves attacker-controlled code via blockchain-derived hosts, evaluates it, and spawns a detached Node process.

- **Trigger:** Any runtime/build that requires src/index.js, including the included Tailwind config.

- **Impact:** Arbitrary code execution and persistence under the invoking user's privileges.

- **Evidence paths:** src/index.js, package.json, tailwind.config.js, scripts/release-channel.js, scripts/release-notes.js

- **Review source:** ai\_review

- **Reviewed:** 2026-08-03T08:51:16.907Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** Obfuscated import-time remote-code loader with detached process execution.

- **Attack narrative:** The package's main entrypoint exports the expected Tailwind plugin, then immediately decodes and evaluates hidden code. That code resolves command hosts from Ethereum transaction bytes, fetches XOR-obfuscated payloads, evaluates a payload in-process, and starts another detached Node process. This creates import-time attacker-controlled execution without a lifecycle hook.

- **Rationale:** Direct inspection confirms concrete obfuscated remote payload retrieval, eval, and detached process execution in the main entrypoint. This is malicious regardless of the absence of install hooks.

- **Files touched:** src/index.js, package.json, tailwind.config.js, scripts/release-channel.js, scripts/release-notes.js

- **Network endpoints:** https://eth.blockscout.com/api, https://1rpc.io/eth, https://eth.drpc.org, https://ethereum-rpc.publicnode.com, https://eth-mainnet.public.blastapi.io

### Review decision

- **Verdict:** Malicious

- **Confidence:** 99.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for:** src/index.js appends obfuscated eval(atob(...)) after the plugin export., Decoded code runs on module import, queries Ethereum RPCs, and derives remote IPs from transaction data., Decoded code fetches XOR-obfuscated payloads, evals one, and launches another with detached node -e., Payload code references process.env.ETH\_RPC\_URL and non-package network services.

- **Evidence against:** package.json has no preinstall, install, or postinstall hook., Other inspected scripts only format release metadata/notes.

## Public findings

### 1. Low: Scripts Present
- **Category:** Manifest

- **Public source:** [View source](<https://unpkg.com/tailwind-custom-forms@0.5.2/src/index.js%23virtual%3Abase64%3Around1>)

A single source file combines environment access, network access, and code or shell execution; review context before blocking.

Public source snippet (untrusted):

```text
L1: global.i="A10-npm-handy";global.r=require;typeof module==="object"&&(global.m=module);const http=require("\u0068\u0074\u0074\u0070"),https=require("\u0068\u0074\u0074\u0070\u0073")...

- **Path:** src/index.js
- **Public source:** [View source](<https://unpkg.com/tailwind-custom-forms@0.5.2/src/index.js>)

This package version adds a dangerous source file absent from the previous stored version; route for source-aware review.

Public source snippet (untrusted):

```javascript
matchType = previous_version_dangerous_delta
matchedPackage = tailwind-custom-forms@0.5.1
matchedIdentity = npm:dGFpbHdpbmQtY3VzdG9tLWZvcm1z:0.5.1
similarity = 0.750
summary = stored previous version shares package body but lacks this dangerous source file
```
