The payload dynamically evaluates fetched content and contains credential-oriented GitHub-token logic. - **Trigger:** npm installation - **Impact:** Arbitrary code execution and potential credential/data exfiltration on the installing host. - **Evidence paths:** package.json, setup.mjs, math\_init.js, dist/index.js - **Review source:** ai\_review - **Reviewed:** 2026-08-04T12:08:26.865Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** install-time staged payload execution with remote code evaluation - **Attack narrative:** Installing the package invokes setup.mjs, which obtains Bun if absent and executes the concealed math\_init.js payload. That payload performs network operations, dynamically evals fetched response content, and contains logic handling GitHub tokens, enabling attacker-controlled code execution and likely credential exfiltration. - **Rationale:** The preinstall chain is unrelated to a chart-theme library and deliberately stages an obfuscated, remotely extensible credential-capable payload. This is concrete malicious install-time behavior. - **Files touched:** setup.mjs, math\_init.js - **Network endpoints:** https://github.com/oven-sh/bun/releases/download/bun-v1.3.13/ ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs \`node setup.mjs\` as preinstall., setup.mjs downloads Bun and executes math\_init.js during installation., math\_init.js is a 728KB obfuscated payload containing remote-response \`eval\`., math\_init.js includes GitHub-token handling, network requests, child-process use, and cleanup. - **Evidence against:** dist entrypoints are small chart-theme exports., No malicious behavior was found in dist/index.js. ## Public findings ### 1. High: Install Time Lifecycle Scripts - **Category:** Manifest - **Confidence:** 90.0% - **Path:** package.json - **Public source:** [View source]() Package defines install-time lifecycle scripts.
