## What is MAL-2026-15926?

MAL-2026-15926 is a malicious package in astlsi, published on 4 Sep 2026. 

### Official description

The package presents itself as a proxy health-check utility, but its exported starts() function walks /storage/emulated/0/ (Android user-storage), collects files with source/document extensions (.py,.json,.txt,.html,.php), packs them into a zip archive, and POSTs the archive to https://tapi.bale.ai/<bot-token>/sendDocument with chat_id 5263487757. The Bale bot token and chat id are hardcoded in the module. The proxy-latency scaffolding around this call performs no real proxy check and serves as a cover story for the single exfiltration request.

The provided functionality hides code that exfiltrates files to a remote location.
