The payload searches GitHub credentials and includes outbound request logic. - **Trigger:** npm preinstall - **Impact:** GitHub credentials may be collected and sent off-host during dependency installation. - **Evidence paths:** package.json, setup.mjs, math\_init.js - **Review source:** ai\_review - **Reviewed:** 2026-08-04T11:57:55.583Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Bun-bootstrapped obfuscated credential harvesting and network exfiltration - **Attack narrative:** npm runs setup.mjs before installation. That script invokes an existing Bun executable or downloads one from GitHub, then runs the hidden math\_init.js payload. Static inspection shows the obfuscated payload uses filesystem, OS, child-process, and outbound-request functionality while enumerating GitHub token material, establishing an unconsented credential-harvesting chain. - **Rationale:** This is concrete install-time execution of an obfuscated payload that targets GitHub credentials, unrelated to the published charting library. The explicit bootstrapper and payload form a malicious chain. - **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 defines preinstall: node setup.mjs., setup.mjs downloads Bun and executes math\_init.js during install., math\_init.js is a 728KB obfuscated credential-harvesting payload., math\_init.js imports child\_process/fs/os/path and contains fetch-based outbound handling., Payload enumerates GitHub token fields including ghtoken, ghs\_old, and ghs\_jwt. - **Evidence against:** dist/picasso.js is a charting-library bundle and does not contain the install payload., The explicit Bun download URL is a legitimate host, but it bootstraps the hidden payload. ## Public findings ### 1.
