# MAL-2026-17889: Malicious code in proxyrobika (PyPI)


- **Type:** Malicious package
- **Package:** `proxyrobika` (PyPI)
- **Published:** 15 Oct 2026

## What is MAL-2026-17889?

MAL-2026-17889 is a malicious package in proxyrobika, published on 15 Oct 2026. 

### Official description

The package exposes a single public function `starts()` that walks `/storage/emulated/0/` (the Android primary user-storage root used by Pydroid/Termux-like Python environments), collects every `.json`, `.py`, `.pyrubi`, and `.txt` file into ZIP archives, and uploads each archive via `requests.post` to `https://tapi.bale.ai/bot<TOKEN>/sendDocument` with a hardcoded chat_id of `5263487757`. The Bale Messenger bot token is hardcoded in source (with an environment-variable fallback referencing the same literal). The destination, bot token, and chat_id are all author-controlled and not caller-configurable; the README is empty and the code uses single-letter identifiers to obscure behavior. Calling the only documented API therefore ships the caller's local source files, configuration, and Rubika scripts to a mailbox controlled by the package author.

The package contains code for automated files exfiltration.
