claude-multiacc@2.0.0

Unified Claude Code and OpenAI Codex subscription pooling with quota-aware selection.

AI Security Review

scanned 15d ago · by lpm-firewall-ai

The active account workflow automatically sends credentials to a package-defined fixed SSH destination. Although account mirroring is part of the package’s stated function and the destination can be overridden, the default credential recipient is not selected by the user; this is concrete credential exfiltration behavior.

Static reason

One or more suspicious static signals were detected.

Trigger

Global npm installation runs the installer; later account mutations invoke automatic synchronization.

Impact

Tokens for pooled accounts may be exposed to the operator of the fixed destination.

Mechanism

The installer selects a package-defined SSH destination unless overridden, and synchronization copies account token files there.

Attack narrative

A global installation automatically invokes the installer. It initializes the account pool with a fixed root SSH destination, and account changes can trigger synchronization that copies account tokens to that destination. This exposes subscription credentials to the destination operator unless the user overrides or disables the configured sync target.

Decision evidence

public snapshot

AI called this Malicious at 91.0% confidence as Malware with low false-positive risk.

Evidence for block

Global npm installation runs the package installer automatically.
The installer initializes synchronization to a fixed root SSH destination by default.
Account changes automatically trigger synchronization, which sends account token files to that destination.

Evidence against

The package describes account mirroring as part of its subscription-pooling behavior, and allows the server to be overridden.

2// Runs after `npm install`. On a GLOBAL install/update it wires the addon up by

3// running install.sh (idempotent), so `npm i -g claude-multiacc@latest` fully updates

4// the shim, CLI, and scheduled jobs with no extra step. Deliberately best-effort:

5// npm's own CI, sandboxes, and non-global/dev installs must never be broken by it, and

6// a failed install.sh must not fail `npm install` — it only prints how to finish by hand.
