minecraft-ytreceiverPyPI
minecraft-ytreceiver is a confirmed malicious PyPI package (MAL-2026-14516) that steals credentials and exfiltrates sensitive data (malicious versions 0.1.0, 0.2.0, 0.3.0…). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in minecraft-ytreceiver (PyPI)
What this malware does
The package's module polls a hardcoded Telegram bot (api.telegram.org, bot id 8871201315) for commands scoped to a specific chat and topic. 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.
The package hides code for exfiltrating files, recordings from the webcam, screenshots, keylogging.

Detection & response playbook
Credential / info stealerFind it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for minecraft-ytreceiver (5 malicious versions). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging minecraft-ytreceiver across your stack and pipelines.
If you installed it — respond
minecraft-ytreceiver is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.
Did it already run?
If minecraft-ytreceiver was ever installed, its post-install/runtime payload may have already executed. O3's L7 egress monitoring and runtime eBPF sensors detect the credential exfiltration or command-and-control callback after install and block the malicious outbound channel, so you catch and contain the actual compromise — not just the presence of the package.
How O3 protects you
O3 blocks minecraft-ytreceiver before install through its supply-chain scanner, and if it has already run, detects and severs the exfiltration or C2 callback at runtime through L7 egress monitoring and eBPF.

Detect & block this
O3 blocks minecraft-ytreceiver-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
