skykoi@2026.3.558

SkyKoi â€” Koi runtime. Multi-channel gateway CLI with RPC Koi.

AI Security Review

scanned 2mo ago · by lpm-firewall-ai

The package has a real, automatically triggered cloud-metadata collection capability, warranting a warning. Source inspection did not establish the concrete exfiltration or install-time attack required for a block.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review

Trigger

User starts the skykoi gateway.

Impact

Cloud environment identity metadata can enter the agent's runtime context.

Mechanism

automatic EC2 IMDS identity collection for agent runtime context

AI rationale

Decision evidence

public snapshot

AI called this Suspicious at 85.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

Gateway startup unconditionally calls initRuntimeContext.
Runtime initialization queries EC2 IMDS identity and IAM-role metadata.
Collected runtime identity is incorporated into the agent world model.

Evidence against

No npm preinstall/install/postinstall hook is declared.
The flagged eval/new Function sites are bundled dependency/wasm glue, not remote-response execution.
The GitHub fetch only parses a WhatsApp dependency version.
