## Verdict summary
**Blocked & quarantined** — The Anthropic credential is disclosed to an unrelated endpoint and reused for API requests.

- **Verdict:** Malicious
- **Product-default install policy:** Block
- **Firewall policy:** Matched malicious
- **Public report status:** Published
- **Threat category:** Credential Exfiltration
- **Selected version:** 1.0.0
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions.

AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy.

The reachable runtime path sends an Anthropic credential to a package-selected unrelated endpoint when the displayed default is retained. This is credential exfiltration and warrants blocking.

## Security analysis

### Published attack-surface review

- **Summary:** The CLI can send an Anthropic API key to the package-default DeepSeek endpoint.

- **Trigger:** On first launch without saved settings, the user selects Anthropic and leaves the default Base URL in place.

- **Impact:** The Anthropic credential is disclosed to an unrelated endpoint and reused for API requests.

- **Evidence paths:** package.json, dist/cli.mjs

- **Review source:** ai\_review

- **Reviewed:** 2026-10-13T22:31:53.565Z

### AI review details

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

- **Mechanism:** Setup saves the API key and Base URL, then runtime configuration applies both to the Anthropic client.

- **Attack narrative:** When first-run setup is used, a user can select Anthropic, enter an Anthropic API key, and accept the displayed default Base URL. The CLI saves that combination and uses the key with the DeepSeek endpoint for Anthropic API calls. The prompt displays the URL, but does not explain that the Anthropic credential will be sent there.

- **Rationale:** The reachable runtime path sends an Anthropic credential to a package-selected unrelated endpoint when the displayed default is retained. This is credential exfiltration and warrants blocking.

- **Files touched:** package.json, dist/cli.mjs

- **Network endpoints:** https://api.deepseek.com

### Review decision

- **Verdict:** Malicious

- **Confidence:** 95.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for block:** package.json exposes dist/cli.mjs as the package entrypoint., dist/cli.mjs sets the default Base URL to https://api.deepseek.com., The interactive setup lets users choose Anthropic, asks for an API key, and offers that package-default Base URL., On first launch without saved settings, the CLI runs setup and saves its result., When Anthropic is selected, the saved key and Base URL are applied to Anthropic environment settings., The Anthropic client uses those settings for its API request.

## Affected versions and remediation

This report applies to @bysking/b-code@1.0.0.

- Avoid installing @bysking/b-code@1.0.0. Remove it from direct dependencies and check your lockfile for transitive copies.
- Choose an independently verified alternative or release. This report does not establish that other versions are safe.
- If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment.
