That payload contains fetched-content eval and credential/token discovery logic. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-04T11:35:50.904Z - **Finished:** 2026-08-04T11:36:17.186Z - **Download time:** 251 ms - **Static scan time:** 469 ms - **AI review time:** 25562 ms - **Total time:** 26282 ms ## Security analysis ### Published attack-surface review - **Summary:** npm installation executes setup.mjs, which obtains a Bun runtime and runs the obfuscated math\_init.js. That payload contains fetched-content eval and credential/token discovery logic. - **Trigger:** npm preinstall - **Impact:** Arbitrary remote code execution and possible theft of developer credentials. - **Evidence paths:** package.json, setup.mjs, math\_init.js, dist/cjs/auth.js - **Review source:** ai\_review - **Reviewed:** 2026-08-04T11:36:17.186Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote bootstrap and obfuscated credential-harvesting payload execution - **Attack narrative:** Installing the package invokes setup.mjs. It downloads and executes Bun solely to run an obfuscated payload; that payload fetches text and evaluates it, and contains token/credential discovery and upload logic. This is unrelated to the published OAuth helper and gives a remote actor install-time code execution. - **Rationale:** The preinstall bootstrap deliberately runs an obfuscated, dynamically evaluated payload with credential-handling code. The benign dist library does not justify this installation 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 \`node setup.mjs\` as preinstall., setup.mjs downloads Bun from GitHub and executes math\_init.js during install., math\_init.js is heavily obfuscated and contains runtime \`eval\` of fetched response content., math\_init.js includes credential/provider discovery and GitHub-token handling logic., The install path executes code absent from the declared dist auth library. - **Evidence against:** dist/cjs/auth.js is a conventional browser OAuth token helper., No benign package function requires an obfuscated install-time Bun bootstrap. ## Public findings ### 1.
