Tonbo Yield: capture your agents' sessions on every machine and list them from any.
AI Security Review
scanned 2d ago · by lpm-firewall-aiThe suspicious indicators resolve to ordinary CLI behavior: Tonbo credentials go to Tonbo’s API, the foreign-looking key strings are explicitly fake test fixtures, and the installer command is only shown as a manual update suggestion. No install hook or concealed automatic credential forwarding was found.
Static reason
One or more suspicious static signals were detected.
Trigger
The CLI runs when invoked; account operations and session capture follow user commands or configured hooks.
Impact
No unauthorized credential forwarding, hidden execution, or other malicious impact was found.
Mechanism
It sends service requests to Tonbo endpoints using Tonbo credentials. The reported third-party credential strings are fake filter test data, and the upgrade shell command is presented as a manual fix.

Decision evidence
public snapshotAI called this Clean at 95.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The manifest exposes a CLI entry point and has no install, preinstall, or postinstall hook.
- Management requests default to https://api.tonbo.dev; bearer credentials are sent to the configured API origin.
- TONBO_API_ORIGIN is an explicit override, and the source requires HTTPS except for loopback HTTP.
- The Anthropic key and JWT strings are explicitly fake test vectors for the secret-filtering behavior.
- The curl installer command is shown as a suggested version-update fix; it is not run automatically.
Evidence against
- The CLI supports network requests and filesystem writes as part of its session capture and account-management features.
- The source includes a shell install command for manual upgrades and checks npm for the latest package version.
