OS AI Agent - YOUR AI AGENT

AI Security Review

scanned 19h ago · by lpm-firewall-ai

Review flagged AI-agent configuration or capability changes. This remains warn-only unless evidence shows foreign-agent hijack through preinstall/install/postinstall, hidden persistence, exfiltration, remote code execution, or other concrete malicious behavior.

Static reason

One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source

Trigger

User runs osai-agent commands such as run, connect, mcp, or skills.

Impact

Potential file/system/SSH changes during agent sessions, subject to mode and confirmation controls.

Mechanism

LLM-driven local/SSH/MCP tool execution with user/configured providers and package server.

Policy narrative

No concrete attack chain was confirmed. The package exposes powerful agent functionality only when the user runs the CLI: it can send task context to a configured server or local provider, receive tool calls, execute local/SSH/MCP actions, and store first-party state under osai-agent paths. There is no lifecycle delivery, foreign agent control-surface mutation, credential harvesting beyond user-configured auth, or hidden persistence found in inspected source.

Rationale

The package is not malicious by the firewall's block criteria because dangerous behavior is user-invoked and package-aligned, with no install hook or foreign AI-agent hijack. It should be warned as a dangerous AI-agent capability surface rather than blocked.

Decision evidence

public snapshot

AI called this Suspicious at 88.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

src/agent/react-loop.js sends prompts/history/cwd/meta to configured server /stream and receives tool calls.
src/tools/local.js exposes LOCAL_CMD, file write/edit/delete, fetch/search, and script execution tools for agent use.
src/services/ssh.js accepts user/device SSH credentials and executes SSH commands on selected hosts.
src/commands/mcp.js and src/tools/mcp-client.js let users register stdio/http MCP servers and call their tools.
src/skills/loader.js can create/load first-party skills under ~/.osai-agent/skills or ./.osai-agent/skills.

Evidence against

package.json has no npm lifecycle hooks, install scripts, or postinstall execution.
Entrypoint src/index.js is a user-invoked CLI dispatcher, not import-time malware.
No evidence of writes to foreign AI-agent surfaces such as CLAUDE.md, Codex/Cursor settings, or .mcp.json.
SSH private key pattern in src/services/ssh.js is validation of user-supplied credentials, not an embedded secret.
Local command execution filters environment variables and applies safety/confirmation checks in src/safety/check.js and tool-executor.js.
Network endpoints are package-aligned AI/provider/auth/search endpoints, with no hidden exfiltration path found.
