It obtains remote configuration and communicates through WebSocket. - **Trigger:** Browser loading or importing dist/common-js.js with a current script element - **Impact:** Consumes visitor CPU/resources for unauthorized cryptocurrency mining. - **Evidence paths:** package.json, dist/common-js.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-16T10:53:36.506Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated cryptomining client with remote configuration and WebSocket control - **Attack narrative:** The package’s main artifact is an obfuscated browser payload that creates an object explicitly labeled XelisMiner and immediately invokes its start path. It can fetch configuration dynamically and establish a WebSocket connection, enabling remote mining-job delivery. The bundled README falsely presents Lodash documentation, supporting deceptive distribution. No install hook is needed: the payload activates when the browser bundle is loaded. - **Rationale:** This is concrete browser cryptomining behavior, not a benign utility or merely suspicious primitive. Dynamic endpoint construction prevents naming a verified host, but does not weaken the confirmed miner and remote-control chain. - **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:** Obfuscated browser bundle instantiates and starts \`XelisMiner\` at runtime., Bundle opens a WebSocket and fetches a configurable remote URL., README presents Lodash material despite this package's unrelated identity. - **Evidence against:** No npm preinstall, install, or postinstall hook; only prepublishOnly is declared. ## Public findings ### 1.
