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. Loading the package executes a concealed remote payload loader. It decodes a network-delivered payload, evaluates it, launches it detached, and erases the loader from the installed entry file. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-11T10:51:47.730Z - **Finished:** 2026-09-11T10:53:16.344Z - **Download time:** 511 ms - **Static scan time:** 73 ms - **AI review time:** 88029 ms - **Total time:** 88614 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:** Loading the package executes a concealed remote payload loader. It decodes a network-delivered payload, evaluates it, launches it detached, and erases the loader from the installed entry file. - **Trigger:** Importing the package main entry, including through the Tailwind configuration plugin load. - **Impact:** Arbitrary code execution in the consumer environment and concealment by modifying the installed package. - **Evidence paths:** package.json, src/index.js - **Review source:** ai\_review - **Reviewed:** 2026-09-11T10:53:16.344Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated remote payload retrieval, decoding, eval, detached process launch, and self-modification. - **Attack narrative:** A consumer imports the configured main entry. Its top-level call runs concealed logic that uses network and blockchain lookup code to obtain a payload, decodes a response header, evaluates the resulting JavaScript, and starts a detached Node process. The entry then rewrites src/index.js to remove the malicious loader while retaining the form-plugin implementation. - **Rationale:** This is concrete import-time remote code execution with a detached child process and self-removal behavior. The absence of an npm lifecycle hook does not mitigate execution through the configured main entry. - **Files touched:** src/index.js ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The manifest exposes src/index.js as the package main entry, so its top-level code runs when consumers load the package., The entry point immediately calls an obfuscated run routine and then rewrites its own source file to remove the injected section., The obfuscated routine decodes a response-header payload, evaluates it, and starts a detached Node process with that payload. - **Evidence against:** package.json contains no npm preinstall, install, or postinstall lifecycle hook., The release helper scripts only derive a release channel or read CHANGELOG.md. ## Affected versions and remediation This report applies to tailwind-form-kit@0.6.2. - Avoid installing tailwind-form-kit@0.6.2. 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.
