On matching messages it downloads a video and forces fullscreen playback while blocking keyboard and mouse input (via keyboard and pynput hooks), kills explorer.exe, and for the /YoutubeCD variant executes `shutdown /s /t 0 /f` to unconditionally power off the host. The bot token, chat id, topic id, and staging directory components are stored as base64 literals decoded at runtime by a helper function; the staging directory is placed at %APPDATA%\\Microsoft\\Crypto\\RSA\\tools to mimic the legitimate Windows RSA key-storage path. At import time the module silently pip-installs undeclared runtime dependencies (requests, keyboard, pynput, psutil) using CREATE_NO_WINDOW to hide the console, then downloads yt-dlp.exe and deno.exe from the mutable `releases/latest` GitHub URLs with no hash verification into the disguised staging path and executes them as part of the remotely driven command chain. pyproject metadata is a placeholder (`Your Name`, no email, homepage, or repository), consistent with a throwaway anonymously published package.\n\n## Source: kam193 (af6c2393210af3735a9353f40789859af7f87c96bcbd00178df62edb2ff7175e)\nThe package hides code for exfiltrating files, recordings from the webcam, screenshots, keylogging.\n\n\n---\n\nCategory: MALICIOUS - The campaign has clearly malicious intent, like infostealers.\n\n\nCampaign: 2026-08-minecraft-ytreceiver\n\n\nReasons (based on the campaign):\n\n\n - spyware-like\n\n\n - files-exfiltration\n\n\n - uses-telegram-bot\n\n\n - keylogger\n\n\n## Affected packages\n\n- `minecraft-ytreceiver`\n\n## Remediation\n\nRefer to the advisory for the patched release.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
