Installing the package or importing the module exfiltrates basic information about the host, and the package has no other purpose. Category: PROBABLY_PENTEST - Packages looking like typical pentest packages, but also anything that looks like testing, exploring pre-prepared kits, research & co, with clearly low-harm possibilities. 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. Judge assessment: This package is a host-enumeration exfiltrator: `setup.py` and `tallyboxlite/__init__.py` both call `_report()` and POST JSON containing `getpass.getuser()` and `socket.gethostname()` to the plaintext OAST collector `https://51wdqvf9yd23cfn5tdxon0jw0doimo9ti.oast.fun/collect`. The attacker model is a dependency-confusion or burner-package install that fingerprints the victim machine and sends the data off-box on install/import, with no legitimate functionality beyond trivial arithmetic helpers. The `oast-exfiltration`, `system-info-exfil`, and `http-exfiltration` findings line up with the actual file contents, and the advisory `MAL-2026-15809` is corroborated by the code rather than merely echoed. The `Security research test package` description does not neutralize the behavior because the package still executes the exfiltration automatically and has no disclosed benign telemetry purpose.
