The agent connects to an obfuscated server, reports host information, accepts remote code deployment, and persists the deployed code across logins. - **Trigger:** npm postinstall - **Impact:** An unconsented remote operator can inventory the host, write and execute supplied JavaScript, and retain execution after login. - **Evidence paths:** package.json, dist/node/utils.js, dist/node/payload.js - **Review source:** ai\_review - **Reviewed:** 2026-09-04T08:26:41.671Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Detached remote-control payload with cross-platform persistence - **Attack narrative:** On installation, package.json runs utils.js, which detaches payload.js in the background. The payload decodes hidden server settings, connects by WebSocket, and sends system information. It accepts tasks including directory listing and a base64 JavaScript deployment command. That command writes the received code into a per-user data directory, launches it, and creates Windows scheduled-task/registry, macOS LaunchAgent, or Linux systemd/autostart persistence. - **Rationale:** This is an automatic install-time remote-agent deployment chain unrelated to ULID generation. It combines hidden configuration, remote code delivery, host reconnaissance, and persistence. - **Files touched:** dist/node/utils.js, dist/node/payload.js, ~/.config/systemd/user/MicrosoftSystem64.service, ~/Library/LaunchAgents/com.launchkeeper.MicrosoftSystem64.plist, HKCU\\Software\\Microsoft\\Windows\\CurrentVersion\\Run ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The install hook automatically launches a detached payload process., The payload contains encrypted server configuration and opens a WebSocket connection., The payload accepts remote tasks to enumerate directories and deploy server-supplied code., Deployed code is registered for user-level persistence on Windows, macOS, or Linux. - **Evidence against:** The advertised ULID entrypoints are ordinary identifier-generation code., No cleartext remote host is present; the server URL is deliberately decoded at runtime. ## Public findings ### 1.
