AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. This is concrete, auto-starting cryptomining behavior in the published runtime entrypoint, not merely a suspicious primitive. The absence of install hooks does not mitigate runtime harm to browser users. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-08-16T13:54:59.214Z - **Finished:** 2026-08-16T13:56:15.259Z - **Download time:** 510 ms - **Static scan time:** 799 ms - **AI review time:** 74734 ms - **Total time:** 76045 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** The browser entrypoint contains an obfuscated Xelis cryptocurrency miner. It automatically starts when loaded in a browser, obtains configuration remotely, and uses workers plus WebSocket mining-pool communication. - **Trigger:** A consumer imports or serves dist/common-js.js in a browser context. - **Impact:** Unauthorized CPU consumption and network use on visitors' devices. - **Evidence paths:** package.json, dist/common-js.js - **Review source:** ai\_review - **Reviewed:** 2026-08-16T13:56:15.259Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Auto-started browser cryptocurrency mining via fetched configuration, WebSockets, and Workers. - **Attack narrative:** The package disguises a browser cryptocurrency miner as common JavaScript/lodash content. Its published, obfuscated entrypoint exports XelisMiner and automatically invokes its startup path in browser contexts. That path can fetch remote configuration, create workers for computation, and connect through WebSocket, enabling mining activity on machines that load an application bundling this package. - **Rationale:** This is concrete, auto-starting cryptomining behavior in the published runtime entrypoint, not merely a suspicious primitive. The absence of install hooks does not mitigate runtime harm to browser users. - **Files touched:** package.json, dist/common-js.js ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** Published browser entrypoint is a 770KB one-line obfuscated payload that brands itself XelisMiner., Importing it in a browser auto-instantiates the miner and invokes its start method., The payload fetches a configurable remote configuration, opens WebSockets, and creates Worker instances for computation. - **Evidence against:** No preinstall, install, or postinstall hook; the only lifecycle hook is prepublishOnly., No Node credential, environment, or local-file harvesting APIs were found in the published entrypoint. ## Affected versions and remediation This report applies to @finaxis/common-js@0.3.10. - Avoid installing @finaxis/common-js@0.3.10. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
