## Verdict summary
**Blocked & quarantined** — Installation environment details and names of potentially sensitive variables are disclosed to an external recipient.

- **Verdict:** Malicious
- **Product-default install policy:** Block
- **Firewall policy:** Matched malicious
- **Public report status:** Published
- **Threat category:** Data Exfiltration
- **Selected version:** 99.0.0
- **Selected version is latest:** Yes
- **Analysis source:** AI Security Review (lpm-firewall-ai)

Trusted malware advisory MAL-2026-16320 identifies this version as malicious. Firewall keeps the version blocked under its trusted-intelligence policy. An AI recommendation to allow or warn does not override that advisory.

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

Automatic npm lifecycle hooks collect installation-host metadata and transmit it to Telegram. This is an unconsented install-time data-exfiltration surface.

## Security analysis

### Published attack-surface review

- **Summary:** Automatic npm lifecycle hooks collect installation-host metadata and transmit it to Telegram. This is an unconsented install-time data-exfiltration surface.

- **Trigger:** npm preinstall or postinstall execution.

- **Impact:** Installation environment details and names of potentially sensitive variables are disclosed to an external recipient.

- **Evidence paths:** package.json, callback.js

- **Review source:** ai\_review

- **Reviewed:** 2026-09-22T00:03:50.496Z

### AI review details

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

- **Mechanism:** callback.js enumerates selected environment variable names, builds host and CI/cloud metadata, and posts it through HTTPS to Telegram.

- **Attack narrative:** Installing the package invokes callback.js before and after installation. The script profiles the host and execution environment, identifies environment-variable names likely related to credentials or infrastructure, and sends the resulting report to a Telegram bot endpoint. Error suppression makes the lifecycle hook less visible to the installer.

- **Rationale:** The package performs automatic install-time host and environment reconnaissance followed by external transmission. Its research labeling does not establish consent for this behavior.

- **Files touched:** callback.js

- **Network endpoints:** api.telegram.org

### Review decision

- **Verdict:** Malicious

- **Confidence:** 99.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for block:** The package automatically runs callback.js during both preinstall and postinstall., The callback inventories environment variable names associated with credentials and cloud or registry services., The callback sends host, user, working-directory, CI/cloud, and sensitive-variable metadata to Telegram.

- **Evidence against:** The main entry point only exports static research metadata, but installation hooks run independently of imports.

## Affected versions and remediation

This report applies to @siriusbeyond/auth@99.0.0.

- Avoid installing @siriusbeyond/auth@99.0.0. 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.
