Malicious code in bittensor-emission-tracker (PyPI)
-= Per source details. Do not edit below this line.=-
The package advertises Bittensor subnet burn-rate monitoring but ships a Cython-compiled darwin.so (core.cpython-310-darwin.so) containing an undocumented clipboard-monitoring daemon. Strings in the binary reveal functions _normalize_clipboard_text, _clipboard_fingerprint, _valid_clipboard_text, and docstrings 'Start clipboard daemon if not running', 'Exclusive lock so only one _run daemon polls clipboard', 'Send Telegram for a phrase. Skips if already sent.', and 'Atomically claim text (SQLite). Returns False if already sent.' — a polling clipboard scraper that deduplicates captured phrases via SQLite and ships each new one to Telegram. The bundled bittensor_emission_tracker/defaults.env hardcodes TELEGRAM_BOT_TOKEN=8666228137:AAF_NLMrow4cDf3uEJCl3JY7DeBHtovd1TU and TELEGRAM_CHAT_ID=8766781014 as the default exfiltration sink for every installer who does not manually override via install --telegram_token. The package's install subcommand registers cross-platform autostart (Windows Task Scheduler with battery/time-limit overrides, Linux systemd user service, macOS LaunchAgent) so the daemon persists across reboots and logins. Distribution as a darwin-only compiled.so with no.pyx source in the wheel conceals the clipboard code path from casual inspection while the README only documents burn-rate alerts. Installing or running this package causes long-term, reboot-persistent exfiltration of any sensitive text the user copies (passwords, seed phrases, API keys, private messages) to the author's Telegram channel.
The package contains code to steal clipboard content to a predefined remote location. If run in the right way, the code will periodically check the clipboard and if the content matches the pattern, exfiltrates it. The targeted data are likely cryptocurrency secret seed phrases.
