# MAL-2026-14158: Malicious code in deepface-weight (PyPI)


- **Type:** Malicious package

- **Published:** 18 Aug 2026

## What is MAL-2026-14158?

MAL-2026-14158 is a malicious package in deepface-weight, published on 18 Aug 2026. 

### Official description

On import, deepface-weight spawns a daemon background thread that polls the installer's working directory for `data/telethon_market_userbot.session` for approximately 10 minutes and POSTs the file to a hardcoded webhook.site endpoint (https://webhook.site/d6ea9c5b-4a85-4e59-9397-2bb5f9407c87). Telethon session files contain live authentication material granting full access to the associated Telegram account. The exfiltration destination is bound to a variable literally named `evil_server_url` with a Russian-language comment identifying it as the attacker's server. The package name mimics the popular `deepface` ML library but ships no machine-learning code; author metadata is a placeholder (`asdqwdasdqwdasd`) with a disposable email at playboot.com.

During import, package exfiltrates the sensitive file with the Telegram session token.
