It retrieves configuration, connects over WebSocket, and launches Workers for computation. - **Trigger:** A consumer loads or imports dist/common-js.js in a browser document. - **Impact:** Unauthorized use of visitor CPU and network resources for cryptocurrency mining. - **Evidence paths:** package.json, dist/common-js.js - **Review source:** ai\_review - **Reviewed:** 2026-08-16T12:39:13.351Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated browser cryptominer with remote configuration and worker execution. - **Attack narrative:** The package presents itself as common/lodash-like code but its declared browser entry embeds an obfuscated XelisMiner. When loaded in a document, the payload auto-creates a miner instance and invokes its start-like method. Its implementation fetches configuration, opens WebSocket connections, and creates Workers, enabling remote-directed browser mining without a user action or clear package purpose. - **Rationale:** The runtime entry contains an automatically invoked, obfuscated Xelis mining payload with remote configuration, WebSocket, and Worker execution. This is concrete unauthorized cryptomining behavior, not a package-aligned utility. - **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:** The declared main entry is a 655KB obfuscated browser payload exposing XelisMiner., On browser import it detects document and immediately constructs and starts the miner., The payload creates WebSocket connections, fetches remote configuration, and spawns Workers. - **Evidence against:** package.json has only a prepublishOnly hook; no install-time lifecycle hook was found., No credential, environment, or local-file harvesting was confirmed. ## Public findings ### 1.
