## Security analysis

### Published attack-surface review

- **Summary:** Install hooks execute a hostname beacon automatically. The hostname is transmitted to a remote IP address.

- **Trigger:** npm preinstall or postinstall

- **Impact:** Discloses the installing machine's hostname to a researcher-controlled endpoint.

- **Evidence paths:** package.json, setup.js, index.js

- **Review source:** ai\_review

- **Reviewed:** 2026-08-07T07:34:13.957Z

### AI review details

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

- **Mechanism:** install-time host identifier exfiltration over HTTP

- **Attack narrative:** During npm installation, both preinstall and postinstall invoke setup.js. It obtains os.hostname(), sanitizes it, then performs an HTTP GET to 89.116.25.133:4444 with the hostname in both the request path and X-PoC-Host header. The package's stated PoC purpose does not establish user consent for this automatic disclosure.

- **Rationale:** Direct source inspection confirms automatic install-time network exfiltration of a host identifier. Although limited in scope, it is concrete behavior rather than a scanner-only signal.

- **Files touched:** setup.js, package.json

- **Network endpoints:** http://89.116.25.133:4444/dpdgroup-css/{hostname}

### Review decision

- **Verdict:** Malicious

- **Confidence:** 98.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for:** package.json runs setup.js in preinstall and postinstall., setup.js reads the install host's hostname., setup.js sends hostname in URL and X-PoC-Host header to 89.116.25.133:4444.

- **Evidence against:** No environment variables, credentials, or local files are read., No persistence, shell execution, or payload download found.
