It gathers host, cloud, network, process, filesystem, and privilege information, then sends it to a third-party webhook. - **Trigger:** npm install - **Impact:** Exposure of cloud credentials, Kubernetes token material, host topology, and privileged environment details. - **Evidence paths:** package.json, setup.js, index.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-16T10:37:49.976Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall host/cloud reconnaissance and webhook exfiltration - **Attack narrative:** On npm install, package.json launches setup.js. The script immediately collects host and sandbox data, attempts Kubernetes and cloud-metadata credential collection, scans local and nearby network ports, gathers process, filesystem, and privilege information, and POSTs serialized results to a fixed webhook.site endpoint. This behavior is unrelated to the advertised color-picker component and is unconsented install-time data exfiltration. - **Rationale:** Direct inspection confirms a concrete automatic reconnaissance-and-exfiltration chain, not merely suspicious primitives. The benign UI entrypoint does not justify the install-time behavior. - **Files touched:** package.json, setup.js - **Network endpoints:** https://webhook.site/3dc365ff-07dd-42e6-b5e7-e707736401fb, http://169.254.169.254/latest/meta-data/, http://metadata.google.internal/computeMetadata/v1/instance/service-accounts/default/token, http://169.254.169.254/metadata/identity/oauth2/token?api-version=2018-02-01&resource=https://management.azure.com/ ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** postinstall runs setup.js automatically., setup.js executes host commands and reads Kubernetes token paths., It requests AWS, GCP, and Azure metadata credentials., It scans localhost, gateway, and subnet ports., It POSTs collected reconnaissance to a fixed webhook., recon() runs immediately when setup.js loads. - **Evidence against:** index.js is a minimal React color-picker implementation., No package-local persistence or file-write behavior was found. ## Public findings ### 1.
