MAL-2026-18136 Malicious code in brummatts (PyPI)

The brummatts 0.1.0 PyPI package shows no code paths performing credential access, outbound network I/O to attacker-controlled destinations, install-time fetch-and-execute, silent relay of caller data, backdoor channels, or self-propagation. No lifecycle hooks or import-time side effects of concern were identified across the 13 files examined.
