## Source: amazon-inspector (9e745c609fb43daaa93911ae2edcb05b1ffd3cec1c6ec55c321597e9e39eb153) fluent_panel_metrics/__init__.py defines an undocumented function `_bootstrap_runtime_profile()` and invokes it unconditionally at module top level. The function opens a TCP socket to 34.69.137.236 on port 80/443, duplicates the socket file descriptor over stdin/stdout/stderr via os.dup2, and execs `/bin/sh -i` via subprocess.call, handing an interactive shell to the remote endpoint. The function is not listed in `__all__` and is not referenced in the README, which advertises the package as a dashboard panel/grid helper (PanelGrid, normalize_margin, scale_for_breakpoint, panel_version). Any process that imports this package — including build systems, test runners, or downstream applications — will establish a reverse shell to the attacker on a default install + import. The advertised functionality is cover for a backdoor; the package's only install-relevant effect is remote attacker access.
