Firewall keeps the version blocked under its trusted-intelligence policy. An AI recommendation to allow or warn does not override that advisory. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Importing the package executes a concealed remote payload loader. It contacts blockchain RPC services to locate a command source, then evaluates and detaches the retrieved code. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-16T23:08:21.879Z - **Finished:** 2026-09-16T23:09:27.950Z - **Download time:** 507 ms - **Static scan time:** 57 ms - **AI review time:** 65506 ms - **Total time:** 66071 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** Importing the package executes a concealed remote payload loader. It contacts blockchain RPC services to locate a command source, then evaluates and detaches the retrieved code. - **Trigger:** Importing or requiring tailwindcss-form through its main entry point. - **Impact:** Arbitrary code can run in the importing user's environment and persist as a detached process. - **Evidence paths:** src/index.js - **Review source:** ai\_review - **Reviewed:** 2026-09-16T23:09:27.950Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated blockchain-addressed remote code execution with self-removal. - **Attack narrative:** The package manifest directs imports to src/index.js. That file begins with an obfuscated loader, contacts Ethereum RPC and indexer endpoints, obtains transaction data that encodes network addresses, retrieves XOR-decoded content, passes it to eval, and launches it through a detached Node child process. It then rewrites src/index.js to remove the loader. - **Rationale:** This is a concealed remote code execution chain unrelated to a Tailwind forms plugin. The absence of install hooks does not mitigate execution on normal package import. - **Files touched:** src/index.js - **Network endpoints:** https://ethereum-rpc.publicnode.com, https://eth.drpc.org, https://1rpc.io/eth, https://api.blockscout.com/api ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The main module is an obfuscated 39 KB single-line payload that runs immediately on import., It queries Ethereum RPC services, derives network addresses from transactions, fetches encrypted content, evaluates it, and starts a detached Node process., The payload overwrites its own source after running, concealing the injected code., The source invokes eval on assembled data and then calls spawn with Node’s -e option. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., The two release scripts only derive a release channel or read CHANGELOG.md. ## Affected versions and remediation This report applies to tailwindcss-form@0.5.1. - Avoid installing tailwindcss-form@0.5.1. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
