It creates workers and communicates with dynamically configured network services. - **Trigger:** Importing dist/common-js.js or loading it in a browser/global environment. - **Impact:** Unauthorized CPU consumption and mining activity in consumer browsers. - **Evidence paths:** package.json, dist/common-js.js - **Review source:** ai\_review - **Reviewed:** 2026-08-16T10:38:11.239Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Auto-started Xelis cryptocurrency mining via Web Workers and WebSocket. - **Attack narrative:** The package declares its obfuscated bundle as the main entrypoint. That bundle defines XelisMiner, automatically instantiates and starts it, creates Web Workers for computation, and uses WebSocket/fetch for dynamically supplied mining configuration. This is concrete unauthorized cryptomining behavior, not a benign utility feature. - **Rationale:** The shipped entrypoint auto-runs an obfuscated Xelis cryptocurrency miner at runtime. The absence of install hooks does not mitigate the malicious import-time/browser execution. - **Files touched:** dist/common-js.js ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Shipped main bundle contains XelisMiner and auto-starts it in a browser/global IIFE., Runtime creates Web Workers, indicating sustained background computation., Bundle opens WebSocket connections and fetches runtime configuration., The distributed artifact is heavily obfuscated, concealing the miner implementation. - **Evidence against:** No install, postinstall, or preinstall hook is declared; prepublishOnly is publish-time only., No fixed network host is visible as a plaintext literal in the inspected bundle. ## Public findings ### 1.
