## Security analysis

### Published attack-surface review

- **Summary:** The browser entrypoint contains targeted disruptive behavior. It can disable page interaction and repeatedly play an externally hosted audio file.

- **Trigger:** Loading the package in a browser with a Russian-language setting on a matching country domain, then revisiting after more than three days.

- **Impact:** Affected users may be unable to interact with the page and may hear persistent audio.

- **Evidence paths:** package.json, lib/RemoteCalibrator.min.js

- **Review source:** ai\_review

- **Reviewed:** 2026-10-07T22:38:27.061Z

### AI review details

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

- **Mechanism:** The bundle stores an initiation date in local storage; on a later visit it disables pointer events and loops audio from flag-gimn.ru.

- **Attack narrative:** When the browser language and hostname match the bundle’s conditions, it saves a local date. After more than three days, it disables page interaction and loops audio from flag-gimn.ru, disrupting the affected page.

- **Rationale:** The published browser entrypoint contains targeted, delayed page disruption and external audio playback. This is concrete protestware behavior, so the package should be blocked.

- **Files touched:** package.json, lib/RemoteCalibrator.min.js

- **Network endpoints:** https://flag-gimn.ru/wp-content/uploads/2021/09/Ukraina.mp3

### Review decision

- **Verdict:** Malicious

- **Confidence:** 99.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for block:** package.json exposes the minified browser bundle as the package entrypoint., The bundle checks for Russian-language browsers on selected country domains and records a first-visit date., After more than three days, the bundle disables page interaction and loops audio from an external host.

## Affected versions and remediation

This report applies to remote-calibrator@0.9.155.

- Avoid installing remote-calibrator@0.9.155. 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.
