@iicp/client@0.7.78

Use the open IICP AI mesh from TypeScript or JavaScript without running a node

AI Security Review

scanned 14d ago · by lpm-firewall-ai

No confirmed malicious attack surface was found. The main unresolved risk is a user-invoked provider CLI with default-on self-update that can globally install a newer @iicp/client from npm during runtime.

Static reason

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

Trigger

User runs iicp-node serve or explicit CLI dependency/update flows.

Impact

Potential supply-chain/control risk from automatic global update, but no inspected code performs install-time compromise, credential theft, or unrelated exfiltration.

Mechanism

runtime npm install/self-update and package-aligned network client/node operations

Attack narrative

A user-invoked provider node can contact the npm registry, install @iicp/client@latest globally, and re-exec itself by default. This is risky operational behavior for a library CLI, but the inspected version does not add lifecycle execution, hidden payload fetching, credential harvesting, or unrelated exfiltration; network and file operations are explained by IICP node/proxy/tunnel functionality.

Rationale

Static source inspection supports a warning for default-on runtime self-update and optional dependency installation, not a malicious block. Suspicious primitives are tied to the advertised node/proxy/tunnel SDK behavior and require user-invoked CLI runtime, with no install/import-time attack found.

Decision evidence

public snapshot

AI called this Suspicious at 82.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

dist/updater.js default-on autoUpdateEnabled checks registry and runs spawn('npm',['install','-g','@iicp/client@latest']) during long-running serve unless IICP_AUTO_UPDATE=0.
dist/cli.js startProviderAutoUpdate wires updater into provider runtime; dist/cli.js installMissing can run npm install --no-save for optional extras when user invokes dependency setup.
dist/tunnel.js spawns existing cloudflared for user-requested/auto NAT Quick Tunnel and writes state under IICP_HOME or ~/.iicp/state.

Evidence against

package.json has no preinstall/install/postinstall hooks; main dist/index.js only re-exports SDK modules.
dist/cli.js executes main only under require.main === module, so importing ./cli does not run commands.
Network endpoints are package-aligned: https://iicp.network/api, npm registry, local backend URLs, Anthropic API, Cloudflare tunnel/DoH.
No source evidence of credential harvesting, arbitrary remote payload execution, destructive filesystem actions, or unconsented install-time behavior.
Identity/token files in dist/identity.js are created for CLI node operation under ~/.iicp with chmod 0600, not exfiltrated in inspected paths.
