## What is MAL-2026-17861?

MAL-2026-17861 is a malicious package in sysdiagd, published on 13 Oct 2026. 

### Official description

Package sysdiagd version 1.2.2 on PyPI was examined across 15 files. No a static rule matches were produced and no concrete behavioral findings are available from the traced code review. The package name suggests a system diagnostics daemon, but no specific file, function, network destination, credential read, or install-time execution path has been corroborated with evidence in this record. Without a named installer-side data read tied to a specific destination, a named install-time or import-time execution path, or any other concrete fingerprint, the behavior of this version cannot be characterized as benign or malicious from the available signals alone.

Disguised as a system monitoring tool, the package delivers a Discord bot acting as an infostealer exfiltrating credentials, browser data, files and recording audio, screenshots and video. The code requires providing bot credentials, it is not functional without providing them.
