## Security analysis

### Published attack-surface review

- **Summary:** Installation invokes a beacon that collects build-host metadata and transmits it off-host via DNS and HTTPS. This is an unconsented lifecycle-time data-exfiltration surface.

- **Trigger:** npm preinstall or postinstall

- **Impact:** Leaks hostname, username, and working-directory data from installing systems.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-08-25T15:42:43.846Z

### AI review details

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

- **Mechanism:** DNS-encoded and HTTPS-query metadata exfiltration

- **Attack narrative:** On installation, npm runs beacon.js during both preinstall and postinstall. The script obtains the local hostname, username, and current working directory, embeds an encoded form in a DNS hostname resolved under b0.rs, and separately sends hostname and cwd to b0.rs by HTTPS. Error suppression and an unconditional successful exit make the callback unobtrusive.

- **Rationale:** Despite its stated research purpose, the package automatically exfiltrates identifying build-environment data during installation through two network channels. This is concrete unconsented install-time data exfiltration.

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

- **Network endpoints:** b0.rs, https://b0.rs/?

### Review decision

- **Verdict:** Malicious

- **Confidence:** 99.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for:** Both preinstall and postinstall execute beacon.js automatically., beacon.js collects hostname, local username, and current working directory., It encodes collected data into DNS labels and performs a lookup to b0.rs., It also sends hostname and cwd in an HTTPS request to b0.rs.

- **Evidence against:** No file writes, shell execution, remote code loading, or destructive action was found., README describes the package as a dependency-confusion research beacon, but this does not remove the unconsented install-time exfiltration.
