What is MAL-2026-15934?
MAL-2026-15934 is a malicious package in dbt-sa-cli, published on 5 Sep 2026.
Official description
setup.py defines rce_poc() and invokes it at module top level, so the code runs unconditionally during pip install dbt-sa-cli. The function collects installer-side identifiers (hostname, USER/USERNAME, current working directory, home path) and sends them out-of-band via a DNS lookup to a subdomain of yokodnssmamqdchvjfyqyo8zaq3s90h8e.oast.fun and an HTTPS POST to https://yokodnssmamqdchvjfyqyo8zaq3s90h8e.oast.fun/dbt-sa-cli. The same install-time path drops a marker file at ~/.dbt-sa-cli-rce-poc in the installer's home directory, demonstrating arbitrary code execution during install. The package name resembles the dbt ecosystem, making this a typosquat lure. Regardless of any 'security research' framing, installing the package produces immediate installer-side data disclosure and code execution against an author-controlled OOB collector.
Installing the package or importing the module exfiltrates basic information about the host, and the package has no other purpose.

Campaign: GENERIC-standard-pypi-install-pentest
Reasons (based on the campaign):
The package contains code to exfiltrate basic data from the system, like IP or username. It has a limited risk.
The package overrides the install command in setup.py to execute malicious code during installation.
What should I do about MAL-2026-15934?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
