## Verdict summary
**Blocked & quarantined** — Installation discloses host and user identifying data to the collector without installer consent.

- **Verdict:** Malicious
- **Product-default install policy:** Block
- **Firewall policy:** Block by default
- **Public report status:** Published
- **Threat category:** Data Exfiltration
- **Selected version:** 1.0.2
- **Selected version is latest:** Yes
- **Analysis source:** AI Security Review (lpm-firewall-ai)

LPM AI independently confirmed malicious behavior in this version and supplies the Firewall block.

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

The manifest directly establishes automatic postinstall activation, local host-data collection, and transmission to a fixed unrelated collector. This is an unconsented installation beacon, so blocking is warranted.

## Security analysis

### Published attack-surface review

- **Summary:** The package has an install-time host fingerprinting request to a fixed external collector. This is a concrete installation disclosure.

- **Trigger:** Installing the package runs its postinstall hook.

- **Impact:** Installation discloses host and user identifying data to the collector without installer consent.

- **Evidence paths:** package.json

- **Review source:** ai\_review

- **Reviewed:** 2026-10-21T03:40:40.619Z

### AI review details

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

- **Mechanism:** The hook gathers local user, host, runtime, OS, and working-directory details and posts them to a fixed webhook.site URL.

- **Attack narrative:** On package installation, the postinstall hook gathers identifying details from the local environment and sends them to a fixed external webhook. The source shows no recipient-specific consent gate.

- **Rationale:** The manifest directly establishes automatic postinstall activation, local host-data collection, and transmission to a fixed unrelated collector. This is an unconsented installation beacon, so blocking is warranted.

- **Files touched:** package.json

- **Network endpoints:** https://webhook.site/8f9e5268-4fcf-47a1-97a8-681b51c1edbc/rce-proof

### Review decision

- **Verdict:** Malicious

- **Confidence:** 99.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for block:** The postinstall hook automatically sends the user, host, Node version, OS, and working directory to a fixed webhook.site URL without a recipient-specific consent gate.

## Affected versions and remediation

This report applies to rootaccessxvv-bbmarker@1.0.2.

- Avoid installing rootaccessxvv-bbmarker@1.0.2. 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.
