The payload includes dynamic remote evaluation and credential/token collection/upload behavior. - **Trigger:** npm install (preinstall) - **Impact:** Remote code execution and credential exfiltration during installation. - **Evidence paths:** package.json, setup.mjs, math\_init.js - **Review source:** ai\_review - **Reviewed:** 2026-08-04T11:33:27.125Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** downloaded runtime executes obfuscated credential-stealing payload with remote eval - **Attack narrative:** Installing the package invokes setup.mjs. It downloads a platform-specific Bun binary from GitHub without integrity verification, executes it against math\_init.js, and that payload includes fetched-response eval plus token/credential harvesting and upload logic. This is unconsented install-time execution unrelated to a Jest configuration package. - **Rationale:** The preinstall chain is concrete and malicious: it bootstraps an obfuscated payload that dynamically executes remote content and harvests credentials. The ordinary Jest files do not mitigate that behavior. - **Files touched:** package.json, 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 setup.mjs during preinstall., setup.mjs downloads and executes Bun, then runs math\_init.js., math\_init.js is a 728KB obfuscated payload., math\_init.js fetches content and passes it to eval., math\_init.js contains credential/token collection and upload control flow. - **Evidence against:** Normal Jest preset and bin files are package-aligned., No benign purpose explains the preinstall payload. ## 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. Public source snippet (untrusted): ```javascript L1: // @bun @bun-cjs L2: var MmgoCP,etDiOOB,JqTtnbZ,bc3Kak,ZQmUTyQ,TTUgga,MDX6yrw,h8wMJNB,CabwE2L,x5ErqV;function WV8StW(MmgoCP,etDiOOB,JqTtnbZ){for(JqTtnbZ=0x0;JqTtnbZ) Package ships non-JavaScript build or shell helper files. Public source snippet (untrusted): ```shell path = bin/test-coverage.sh kind = build_helper sizeBytes = 300 magicHex = [redacted] ``` ### 10. Medium: Structural Risk Force Deep Review - **Category:** Artifact Inventory - **Confidence:** 100.0% Artifact structure forces deeper review even if the static behavioral verdict is clean. ### 11. High: Known Malware Source Similarity - **Category:** Static - **Confidence:** 97.0% - **Path:** setup.mjs - **Public source:** [View source]() Source file is highly similar to a previously finalized malicious package; route for source-aware review.
