The service response is executed as JavaScript with Node capabilities. - **Trigger:** npm postinstall - **Impact:** Remote operator can execute arbitrary Node-capable payloads during installation and receive host identifiers. - **Evidence paths:** package.json, src/utilities/SubscriptionGuard.js, index.js - **Review source:** ai\_review - **Reviewed:** 2026-07-22T12:56:41.122Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** host fingerprinting followed by remotely supplied code execution - **Attack narrative:** Installing the package invokes SubscriptionGuard.js. It sends the host MAC address, platform, and local package path to a remote entitlement endpoint, then fetches JavaScript from that service. A nonfunctional hard-coded hash check always passes, and the code is run in a VM context exposing require and process, enabling remote arbitrary code execution at install time. - **Rationale:** This is a concrete install-time fingerprinting and remote-code-execution chain unrelated to a React Native toast library. The fake integrity verification provides no meaningful protection. - **Files touched:** package.json, src/utilities/SubscriptionGuard.js - **Network endpoints:** https://react-native-ui-message.com/api/EntitlementState, https://react-native-ui-message.com/api/ValidateLicense/{token}/{result} ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json postinstall runs SubscriptionGuard.js automatically., SubscriptionGuard.js collects MAC address, OS, and package path., It POSTs host data to the package-controlled entitlement endpoint., It GETs server-provided JavaScript and executes it with vm.runInContext., The purported hash check compares two hard-coded identical values, so it does not validate remote code., VM context exposes require, process, Buffer, and timers to remote code. - **Evidence against:** index.js itself only exports UI library modules; the harmful path is install-time. ## Public findings ### 1.
