SkyForge binary for linux x64

AI Security Review

scanned 14h ago · by lpm-firewall-ai

No confirmed malicious attack surface was established. The package exposes a user-invoked native CLI and bundled MCP resources, with no install-time execution.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

Explicit invocation of the skyforge CLI or MCP runtime

Impact

No covert payload execution or unconsented mutation confirmed

Mechanism

User-invoked CLI/MCP functionality

Rationale

Direct inspection shows a platform-specific CLI package with bundled MCP/UI assets but no lifecycle hook or concrete malicious chain. Dynamic code-generation matches bundled validation tooling rather than remotely sourced execution.

Evidence

package.jsonbin/sky-codemcp/nexus.jsmcp/nexus-http.jspackages/app/dist/assets/session-eRe7mVtg.js

Decision evidence

public snapshot

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

Evidence for block

`mcp/nexus.js` contains bundled `new Function` code-generation primitives.
`bin/sky-code` is a native ELF executable exposed through the user-invoked CLI.

Evidence against

`package.json` has no preinstall, install, postinstall, or other lifecycle scripts.
`mcp/nexus.js` has no matched fetch, child_process, spawn, exec, or process.env primitive.
The flagged CDN URLs in `mcp/nexus.js` are embedded asset/template references, not a confirmed fetched-and-executed payload.
`mcp/nexus-http.js` endpoints are ServiceNow/example documentation and runtime configuration examples.
No source evidence shows credential harvesting, exfiltration, persistence, destructive behavior, or AI-agent control-surface mutation.
