SkyKoi — Koi runtime. Multi-channel gateway CLI with RPC Koi.

AI Security Review

scanned 2mo ago · by lpm-firewall-ai

No concrete malicious install hook, stealth persistence, or remote payload execution was confirmed. The package nevertheless has a real, high-impact capability to transmit captured device data, so it warrants a warning.

Static reason

High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source

Trigger

Run the gateway with an approved capture policy and configured platform credentials.

Impact

Sensitive screen, audio, terminal, calendar, notification, and message content can leave the device.

Mechanism

Proactive device-context collection and remote AI inference.

Decision evidence

public snapshot

AI called this Suspicious at 90.0% confidence as Dangerous Capability with low false-positive risk.

Evidence for warning

dist/proactive-eval-CdSfwm7j.js assembles screen/OCR, terminal, audio, calendar, notification, message, and profile context.
That bundle POSTs the assembled context to `${platformUrl}/api/ai/anthropic/v1/messages`.
dist/capture-service-49BUIHTm.js starts the proactive evaluator when approved capture is active.
dist/reply-Bw-0P-62.js eval/Function findings are vendored dependency internals, not remote-response execution.

Evidence against

package.json has no preinstall/install/postinstall hooks.
dist/capture-policy-8RA9vGYq.js is deny-by-default and requires enabled policy, purpose, and named sources.
The remote AI call requires configured koiId and gateway token.
