The function uses `subprocess.Popen` to launch `pythonw.exe` (replacing `python.exe` in `sys.executable`) running a sibling file `_snapqueue_core.py` with `creationflags=0x08000000` (CREATE_NO_WINDOW), and wraps the whole call in a blanket `try/except: pass`. Standard modules are aliased under underscore names (`_os`, `_sys`, `_sp`) to reduce visual prominence. The launched `_snapqueue_core.py` is undocumented in README and package metadata and is unrelated to the advertised FIFO-queue functionality. The combined shape \u2014 install-time execution, deliberate console-window suppression on Windows, error-swallowing, and detachment of the child from the pip process \u2014 is a hidden install-time stager that hands control on the installer\u0027s machine to undocumented sibling code the moment the package is installed.\n\n## Source: kam193 (62bf582784fd41b3484157f6454ddcb6ab2ae10a5d93abeb19a5bfa5642b7e64)\nDuring installation, the package attempts to silently execute code. In analyzed versions, the payload file was missing.\n\n\n---\n\nCategory: MALICIOUS - The campaign has clearly malicious intent, like infostealers.\n\n\nCampaign: 2026-09-snap-queue\n\n\nReasons (based on the campaign):\n\n\n - The package overrides the install command in setup.py to execute malicious code during installation.\n",
