MAL-2026-6182 Malicious code in fluent-panel-metrics (PyPI)

fluent_panel_metrics/init.py defines _bootstrap_runtime_profile() and invokes it unconditionally at module load. The function opens a TCP socket to the hardcoded IP 34.69.137.236 on port 443 (with fallback to port 80), duplicates the socket file descriptor onto stdin/stdout/stderr via os.dup2, and execs /bin/sh -i via subprocess.call — a textbook interactive reverse shell. Any process that runs import fluent_panel_metrics hands an interactive shell to the remote endpoint. The package's METADATA advertises it as a small dashboard layout helper (PanelGrid, normalize_margin, scale_for_breakpoint) with no documented network behavior, and the reverse-shell call is not referenced in all, README, or metadata — a cover-story package whose only real effect is the backdoor.

During import, the package starts a reverse shell.

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

Campaign: 2026-06-acme-widget-layout-utils

Reasons (based on the campaign):

• The package contains code to create a reverse shell, allowing an attacker to execute any commands on the victim's machine.
