MAL-2026-17861 Malicious code in sysdiagd (PyPI)

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.

Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers.
