The payload contains remote code evaluation and credential-harvesting behavior. - **Trigger:** npm installation - **Impact:** Remote code execution and theft of local credentials/tokens. - **Evidence paths:** package.json, setup.mjs, math\_init.js - **Review source:** ai\_review - **Reviewed:** 2026-08-04T11:30:32.984Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** downloads/executes Bun to run obfuscated math\_init.js - **Attack narrative:** Installing the package invokes setup.mjs. It uses an existing Bun binary or downloads one from GitHub, then runs the bundled obfuscated math\_init.js. That payload includes logic to fetch a remote response and eval it, plus credential/token collection including AWS and GitHub-related material. This is an unconsented install-time remote execution and credential-exfiltration chain. - **Rationale:** The lifecycle script is unrelated to a Jest configuration package and deliberately launches an obfuscated credential-capable payload at preinstall. The conventional preset files do not mitigate this concrete malicious chain. - **Files touched:** package.json, setup.mjs, math\_init.js, /etc/os-release - **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/executes Bun, then executes math\_init.js., math\_init.js is heavily obfuscated and contains remote-response eval., math\_init.js contains credential-harvesting logic, including GitHub tokens and .aws., The preinstall chain executes without a user command. - **Evidence against:** jest-preset.js is a conventional Jest preset., The Bun download host is github.com/oven-sh/bun. ## 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. Public source snippet (untrusted): ```json scripts.preinstall = node setup.mjs ``` ### 2. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 3. Low: Eval - **Category:** Source - **Confidence:** 45.0% - **Path:** math\_init.js - **Public source:** [View source]() Package source references a known benign dynamic code generation pattern.
