It obtains configuration remotely and creates workers that consume client CPU. - **Trigger:** Importing or including dist/common-js.js in a browser page. - **Impact:** Unauthorized CPU/resource consumption and mining-pool network activity. - **Evidence paths:** package.json, dist/common-js.js - **Review source:** ai\_review - **Reviewed:** 2026-08-15T20:29:05.644Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Auto-started remote-configured Web Worker cryptominer. - **Attack narrative:** The package advertises a common/lodash-like library but its sole published entrypoint is an obfuscated bundle defining XelisMiner. In a browser it reads the current script, constructs the miner, fetches configurable (including decryptable) settings, opens mining communication, and starts worker threads automatically. This is concealed unauthorized cryptocurrency mining. - **Rationale:** Source inspection confirms an automatically activated, obfuscated browser cryptominer rather than a package-aligned utility. The absence of a consumer install hook does not mitigate runtime execution on browser inclusion. - **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:** Published entrypoint is an obfuscated browser bundle., Bundle defines XelisMiner and creates Web Workers for mining., It fetches a remote config and can decrypt it before use., Browser-script import auto-instantiates and starts the miner. - **Evidence against:** No consumer install lifecycle hook is declared; prepublishOnly is publisher-side. ## Public findings ### 1.
