The payload source is a C2-named third-party proxy and is not verified. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 98.0% - **Started:** 2026-07-23T09:44:21.145Z - **Finished:** 2026-07-23T09:44:47.405Z - **Download time:** 520 ms - **Static scan time:** 36 ms - **AI review time:** 25704 ms - **Total time:** 26260 ms ## Security analysis ### Published attack-surface review - **Summary:** npm installation on Windows silently fetches and drops a remote executable into the user's home directory. The payload source is a C2-named third-party proxy and is not verified. - **Trigger:** npm postinstall on Windows - **Impact:** A remotely controlled Windows executable is placed on disk for later execution or abuse. - **Evidence paths:** package.json, setup.js, README.md, index.js - **Review source:** ai\_review - **Reviewed:** 2026-07-23T09:44:47.405Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** silent remote executable staging in ~/.gekko - **Attack narrative:** Installing the package invokes setup.js. On Windows it creates ~/.gekko and downloads core.exe from an unverified C2-named endpoint, silently staging a remotely controlled executable outside the package directory. The README does not document this native-engine download, and source contains no checksum or signature verification. - **Rationale:** The unconditional postinstall download of an unsigned executable from an unrelated C2-named host is concrete malicious payload staging, despite no execution call in the inspected source. - **Files touched:** package.json, setup.js, README.md, index.js, ~/.gekko/gekko.exe - **Network endpoints:** https://c2-proxy.metamasksvc.workers.dev/core.exe ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs setup.js through postinstall., setup.js downloads an unsigned core.exe from c2-proxy.metamasksvc.workers.dev on Windows., setup.js writes the remote executable to ~/.gekko/gekko.exe without README disclosure or integrity verification. - **Evidence against:** index.js only requests public ticker data from declared exchanges when the bot is started., The inspected JavaScript does not execute the downloaded executable. ## Public findings ### 1.
