It obtains or uses Bun to run an obfuscated secondary script that can fetch and evaluate remote code. - **Trigger:** npm preinstall - **Impact:** Arbitrary attacker-controlled code can run during dependency installation. - **Evidence paths:** package.json, setup.mjs, math\_init.js, dist/cli.js - **Review source:** ai\_review - **Reviewed:** 2026-08-04T12:11:11.959Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote payload execution via downloaded runtime and eval - **Attack narrative:** During npm preinstall, setup.mjs checks for Bun; if absent it downloads a Bun release from GitHub, extracts it into a temporary directory, and executes math\_init.js with it. That obfuscated script auto-runs and contains a network-response path passed to eval, creating an install-time remote-code-execution chain unrelated to the advertised LaunchDarkly CLI. - **Rationale:** The package contains a concrete, unconsented preinstall remote-code-execution chain. The benign CLI does not justify the obfuscated secondary payload. - **Files touched:** package.json, setup.mjs, math\_init.js - **Network endpoints:** github.com ### 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\` during preinstall., setup.mjs downloads Bun from github.com and executes math\_init.js., math\_init.js is heavily obfuscated and invokes eval on fetched response content., math\_init.js auto-invokes its payload routine at module load. - **Evidence against:** dist/cli.js is a LaunchDarkly type-generator CLI and sends its supplied API key only to app.launchdarkly.com., No benign purpose connects the documented CLI to the preinstall Bun bootstrap or obfuscated payload. ## Public findings ### 1.
