That payload can fetch text at runtime and evaluate it as code. - **Trigger:** npm preinstall - **Impact:** Arbitrary code execution in the installing user's environment. - **Evidence paths:** package.json, setup.mjs, math\_init.js - **Review source:** ai\_review - **Reviewed:** 2026-08-04T12:13:47.161Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** install-time remote payload retrieval and eval - **Attack narrative:** The preinstall hook runs setup.mjs, which executes math\_init.js directly or first downloads and executes Bun to run it. The unusually large obfuscated math\_init.js imports host and network capabilities, retrieves response text, and evaluates it. This provides an install-time remote code-execution chain unrelated to the advertised OAuth plugin. - **Rationale:** Concrete preinstall execution, downloader behavior, obfuscation, and runtime eval establish malicious install-time remote code execution. - **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 as preinstall., setup.mjs executes math\_init.js during installation., setup.mjs downloads and executes Bun from GitHub if unavailable., math\_init.js is a 727KB heavily obfuscated executable payload., math\_init.js imports fs, network, DNS, crypto, OS, and child\_process., math\_init.js fetches response text and passes it to eval(). - **Evidence against:** src/ and dist/ implement plausible Verdaccio/Okta OAuth flows., No benign source path justifies the obfuscated install-time 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.
