anon-pi@0.11.0

Launch pi inside a netcage: anonymized web egress through a socks5h proxy, one direct hole for a local model, seeded pi config on the host.

AI Security Review

scanned 1d ago · by lpm-firewall-ai

No confirmed malicious attack surface. The package is a CLI launcher for pi inside netcage and its risky primitives are user-invoked, package-aligned container/process/file operations.

Static reason

One or more suspicious static signals were detected.

Trigger

User runs anon-pi CLI commands such as init, launch, machine, forward, ports, or delete verbs.

Impact

Creates and updates anon-pi configuration/machine/project state; can delete anon-pi homes/projects only via explicit delete commands with confirmation.

Mechanism

user-invoked netcage/podman orchestration and anon-pi state-file management

Rationale

Static inspection shows suspicious scanner hits are explained by the package's documented CLI purpose: launching netcage/podman, probing a user-selected proxy/local model, and managing anon-pi state. There is no lifecycle execution, unconsented agent-control mutation, exfiltration path, or hidden persistence.

Decision evidence

public snapshot

AI called this Clean at 91.0% confidence as Benign with low false-positive risk.

Evidence for block

Evidence against

package.json has no install/preinstall/postinstall lifecycle hooks; only a user-invoked bin ./dist/cli.js.
dist/cli.js child_process use is for explicit CLI actions: netcage launch/verify/query, podman image build/load, and local node helpers.
dist/cli.js writes under resolved anon-pi home such as config.json, models.json, settings-seed.json, machine.json, and project/machine dirs.
dist/cli.js refuses non-TTY init and requires user confirmation for delete operations.
dist/anon-pi.js validates project/machine names and composes netcage args with forced --proxy and one --allow-direct local model endpoint.
No foreign AI-agent control-surface writes, credential exfiltration, remote payload loading, or install-time execution found.
