The package ships a macOS arm64 Rust-compiled Python extension (_core.abi3.so) fronted by a thin wrapper lb.py. The only exposed Python function, shortname(), invokes two gibberish-named native entrypoints (_core.dphjx0rdhx0 and _core.ioluli0x0xthf) and swallows all exceptions with a silent print(''). The native binary embeds the hardcoded path 'Library/Application Support/Telegram Desktop/tdata' (the installer's Telegram Desktop session store on macOS), the archive name 'fghj.zip', and the destination 'https://api.telegram.org', alongside zip, AES, ChaCha20 and reqwest/rustls/hyper HTTP client code. This matches packaging the installer's live Telegram Desktop session directory and uploading it to a Telegram bot controlled by the author, which grants full takeover of the installer's Telegram account. The random-looking native export names and the blanket exception suppression serve to hide the behavior from casual inspection; the package's self-description as an OSINT utility does not match its actual data flow, which targets the installer's own messaging session store rather than any user-supplied target.
When used, the package exfiltrates Chrome extension files (likely targeting cryptocurrency wallets) and sensitive Telegram files.
