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 starts a detached background loader. That loader retrieves attacker-controlled code and executes it locally with require and filesystem context. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-15T02:59:33.373Z - **Finished:** 2026-09-15T03:00:09.225Z - **Download time:** 260 ms - **Static scan time:** 18 ms - **AI review time:** 35573 ms - **Total time:** 35852 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 starts a detached background loader. That loader retrieves attacker-controlled code and executes it locally with require and filesystem context. - **Trigger:** An application imports process-tailwind or explicitly imports its loader entrypoint. - **Impact:** Remote code execution in the importing application's user context, with background-process persistence until terminated. - **Evidence paths:** index.js, init.js, loader.js - **Review source:** ai\_review - **Reviewed:** 2026-09-15T03:00:09.225Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Detached remote payload loader using dynamic function execution. - **Attack narrative:** A normal import calls initialize, which spawns loader.js detached and suppresses its standard streams. The loader downloads a JSON field named code from api.npoint.io, base64-decodes it, and runs it through new Function while supplying require and local path values. The remote operator can therefore change code executed in every importing application without publishing a new package version. The detached process and PID file keep the loader running independently of the importing process. - **Rationale:** This package contains an import-triggered detached remote-code loader, not the runtime utilities claimed by its manifest. The remote payload is executed with Node module access, creating concrete remote code execution. - **Files touched:** index.js, init.js, loader.js, .pid - **Network endpoints:** https://api.npoint.io/24c25d5f5fcbb0992a4f ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** Importing the main entry immediately starts the initializer., The initializer launches a detached loader and records its process ID., The loader fetches base64 code from a remote endpoint and executes it with Node module access., The loader globally intercepts child-process imports and hides Windows child windows. - **Evidence against:** The manifest contains no npm preinstall, install, or postinstall hook., No credential harvesting or exfiltration is present in the inspected package source. ## Affected versions and remediation This report applies to process-tailwind@1.1.99. - Avoid installing process-tailwind@1.1.99. 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.
