It retrieves staged code from dynamically derived network infrastructure, evaluates it, and starts detached hidden processes. - **Trigger:** Running \`server.js\` (including the package \`dev\` script) imports \`src/app.js\` and then the poisoned route. - **Impact:** Arbitrary attacker-controlled code execution and persistence-like background process launch. - **Evidence paths:** package.json, server.js, src/app.js, playground/src/routes/auth.routes.js, src/utils/fileHelper.js - **Review source:** ai\_review - **Reviewed:** 2026-07-29T20:38:45.949Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated staged remote-code loader with detached-process execution. - **Attack narrative:** On application startup, \`server.js\` imports \`src/app.js\`, which imports \`playground/src/routes/auth.routes.js\`. Code appended after the normal router dynamically decodes a second stage, queries JSON-RPC for encoded transaction data, derives a host from it, fetches encrypted payloads over HTTPS, evaluates one, and launches another detached with hidden windows. The endpoint is intentionally computed at runtime rather than present as a literal. - **Rationale:** The package contains a concrete concealed remote-code execution chain unrelated to its advertised scaffolding function. Absence of an install hook does not mitigate execution when its server entrypoint runs. - **Files touched:** server.js, src/app.js, playground/src/routes/auth.routes.js ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** \`playground/src/routes/auth.routes.js\` appends an obfuscated immediately invoked payload after the router., The payload dynamically constructs functions, decrypts staged code, and calls \`eval\`., It queries a blockchain JSON-RPC service for transaction data to derive command-and-control data., It downloads XOR-decoded code over HTTPS and launches it detached with hidden windows., \`src/app.js\` imports the poisoned route, so \`node server.js\` activates it at runtime. - **Evidence against:** \`package.json\` has no install lifecycle hook., The CLI scaffold writer in \`src/utils/fileHelper.js\` is otherwise user-invoked and package-aligned. ## Public findings ### 1.
