## Security analysis

### Published attack-surface review

- **Summary:** Install-time code exfiltrates host identifiers and the install path through DNS queries. No user command is required beyond package installation.

- **Trigger:** npm installation, via the preinstall lifecycle hook

- **Impact:** Leaks the installing account name, hostname, and current working directory to a third-party DNS domain.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-07-30T11:31:54.859Z

### AI review details

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

- **Mechanism:** DNS-based host metadata exfiltration

- **Attack narrative:** During npm preinstall, the package collects the local username, hostname, and working directory, serializes and hex-encodes them, then embeds chunks in DNS lookup subdomains under a third-party domain. This silently transmits installation-host metadata before normal package use.

- **Rationale:** The package has no declared functionality beyond an automatic preinstall script that covertly sends local host metadata over DNS. This is concrete, unconsented install-time data exfiltration.

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

- **Network endpoints:** d9jfvjgl8o8s72utl810ktk61s1xmsysr.o.jgl.red

### Review decision

- **Verdict:** Malicious

- **Confidence:** 99.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for:** package.json runs \`node preinstall.js\` automatically., preinstall.js collects username, hostname, and working directory., preinstall.js hex-encodes the collected data into DNS labels., preinstall.js performs DNS lookups to \`d9jfvjgl8o8s72utl810ktk61s1xmsysr.o.jgl.red\`., Errors are silently ignored.
