## Security analysis

### Published attack-surface review

- **Summary:** Automatic npm lifecycle scripts fingerprint the installer environment and transmit it to an external callback domain. Both preinstall and install perform the behavior without user action.

- **Trigger:** npm preinstall/install lifecycle execution

- **Impact:** Leaks installer username, hostname, working directory, and package identifier to an external operator.

- **Evidence paths:** package.json, index.js, README.md

- **Review source:** ai\_review

- **Reviewed:** 2026-08-13T20:34:46.249Z

### AI review details

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

- **Mechanism:** base64-encoded host fingerprint exfiltration through HTTPS path and DNS query

- **Attack narrative:** On installation, the package builds a base64 value containing \`whoami\`, hostname, current directory, and its package name. It places that value in an HTTPS request path and sends a second encoded package-derived value through DNS to callback.m0chan.co.uk. The duplicate preinstall and install hooks make this unconsented exfiltration automatic.

- **Rationale:** Direct manifest inspection confirms two install-time scripts that fingerprint and exfiltrate the installer environment to an unrelated external callback domain. The empty runtime entrypoint does not mitigate this concrete lifecycle attack.

- **Files touched:** package.json, index.js, README.md

- **Network endpoints:** callback.m0chan.co.uk, https://$pkgsub.callback.m0chan.co.uk/$b64

### Review decision

- **Verdict:** Malicious

- **Confidence:** 99.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for:** \`preinstall\` collects username, hostname, working directory, and package name, then exfiltrates encoded data through HTTPS and DNS., \`install\` repeats the same automatic host-environment exfiltration.

- **Evidence against:** \`index.js\` only exports an empty object; no additional runtime payload was found., README contains only a generic package description.
