## Verdict summary
**Blocked & quarantined** — A non-ZAN Anthropic or OpenAI credential may be disclosed to the ZAN service and agent traffic can be redirected there.

- **Verdict:** Malicious

- **Threat category:** Credential Exfiltration
- **Selected version:** 1.0.0
- **Selected version is latest:** Yes
- **Analysis source:** AI Security Review (lpm-firewall-ai)

A user-invoked setup can read a pre-existing Claude or Hermes credential and transmit it to ZAN before confirmation. It then redirects selected agent configuration to ZAN.

## Security analysis

### Published attack-surface review

- **Summary:** A user-invoked setup can read a pre-existing Claude or Hermes credential and transmit it to ZAN before confirmation. It then redirects selected agent configuration to ZAN.

- **Trigger:** Running zan-router setup, auto, or an agent setup subcommand on an existing Claude/Hermes configuration.

- **Impact:** A non-ZAN Anthropic or OpenAI credential may be disclosed to the ZAN service and agent traffic can be redirected there.

- **Evidence paths:** dist/cli.js, dist/chunk-LRKSX7C5.js, package.json

- **Review source:** ai\_review

- **Reviewed:** 2026-08-21T11:40:20.193Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** credential harvesting from agent configs followed by pre-confirmation API verification and endpoint redirection

- **Attack narrative:** On setup, the CLI reads existing agent keys before obtaining user confirmation. For Claude it accepts ANTHROPIC\_AUTH\_TOKEN without checking that it is a prior ZAN credential; for Hermes it can accept OPENAI\_API\_KEY. It then verifies the key by POSTing it in authorization headers to the default ZAN endpoint. Only after this network transmission does the CLI display its review/apply confirmation and write provider redirection settings.

- **Rationale:** This is concrete credential exfiltration from foreign agent configuration to a package-controlled endpoint before consent, not merely an explicit configuration helper.

- **Files touched:** ~/.claude/settings.json, ~/.hermes/.env, ~/.codex/config.toml, ~/.openclaw/openclaw.json, ~/.config/opencode/opencode.json, ~/.neovate/config.json

- **Network endpoints:** https://ai.zan.top/v1

### Review decision

- **Verdict:** Malicious

- **Confidence:** 97.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for:** Setup reads credentials from existing agent configs before the user confirms changes., Claude extraction accepts any existing ANTHROPIC\_AUTH\_TOKEN; Hermes also falls back to OPENAI\_API\_KEY., The extracted key is sent as an Authorization/x-api-key header to the ZAN API., The default receiver is https://ai.zan.top, and confirmation occurs only after verification.

- **Evidence against:** package.json has no npm lifecycle hooks., Network requests are confined to the advertised ZAN endpoint and setup is user-invoked.

## Public findings

### 1. Low: Scripts Present

Source sends credentials or rich application records to a package-controlled external receiver enabled by default.

Public source snippet (untrusted):

```javascript
Source sends the broad process environment to a literal external destination.
L99: if (this.mode === "json") {
L100: this.writeStdout(withSingleTrailingNewline(JSON.stringify(jsonValue2) ?? "null"));
L101: return;
...
L143: colorsEnabled() {
L144: return !this.noColor && process.env.NO_COLOR === void 0;
L145: }
...
L152: writeStdout: (value) => {
L153: process.stdout.write(value);
L154: },
...
L276: const onData = (buffer) => {
L277: for (const character of buffer.toString("utf8")) {
L278: if (character === "" || character === "") return finish(new SetupCancelledError());
```

### 6. High: Credential Redirect Persistence

Manifest-reachable source sends a prompted API credential to a fixed unofficial gateway and persists the redirection.

Public source snippet (untrusted):

```javascript
Manifest-reachable source captures an API credential, sends it to a fixed unofficial gateway, and persists that redirection in agent or shell configuration.
dist/cli.js:
openAIBaseUrl,
import readline from "readline/promises";
"API Key (Enter to keep existing, or paste a new key to replace, Ctrl+C to cancel): "
console.error("\u2717 Invalid API key format. Expected a key beginning with sk-.");
const apiKey = await readHiddenInput("Paste your ZAN API Key (Ctrl+C to cancel): ");
console.error("\u2717 Invalid API key format. Use a ZAN key beginning with sk-, or press Ctrl+C to cancel.");
const rl = readline.createInterface({ input: process.stdin, output: process.stdout });
const rl = readline.createInterface({ input: process.stdin, output: process.stdout });
```

### 7. Low: High Entropy Strings
- **Category:** Supply Chain
- **Confidence:** 55.0%

Package source contains high-entropy string patterns.

### 8. Low: Url Strings
- **Category:** Supply Chain
- **Confidence:** 65.0%

Package source contains URL literals.

### 9. Medium: Structural Risk Force Deep Review
- **Category:** Artifact Inventory
- **Confidence:** 90.0%

Artifact structure forces deeper review even if the static behavioral verdict is clean.

Setup reads credentials from existing agent configs before the user confirms changes.

Public source snippet (untrusted):

```javascript
const { readAgentApiKey: readAgentApiKey2 } = await import("./inspect-OW4NQGNL.js");
  const [existingKeys, existingInspections] = await Promise.all([
    Promise.all(agents.map((agent) => readAgentApiKey2(agent))),
    Promise.all(agents.map((agent) => inspectAgentConfig(agent, {}, detected)))
  ]);
  const alreadyConfigured = existingKeys.some((k) => k !== null);
  const existingKey = existingKeys.find((k) => k !== null) ?? null;
  if (alreadyConfigured) {
```

### 12. High: Ai Review Evidence

Claude extraction accepts any existing ANTHROPIC\_AUTH\_TOKEN; Hermes also falls back to OPENAI\_API\_KEY.

Public source snippet (untrusted):

```javascript
async function readAgentApiKey(agent) {
  try {
    if (agent === "claude-code") {
      const source = await readOptional(claudeSettingsPath());
      if (!source) return null;
      const settings = JSON.parse(source);
      return settings.env?.ANTHROPIC_AUTH_TOKEN ?? null;
    }
