## Security analysis

### Published attack-surface review

- **Summary:** The browser entrypoint contains targeted disruption for visitors using Russian-language browser settings on selected host suffixes. After a persistent three-day delay, it blocks page interaction and plays looping audio.

- **Trigger:** The bundle runs in a browser, the browser language begins with ru, and the current host ends in .ru, .su, .by, or .xn--p1ai; the stored initiation date must be more than three days old.

- **Impact:** Affected visitors lose normal page interaction and hear repeated audio.

- **Evidence paths:** lib/RemoteCalibrator.min.js

- **Review source:** ai\_review

- **Reviewed:** 2026-10-07T22:38:28.995Z

### AI review details

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

- **Mechanism:** It sets the document body’s pointer events to none, creates an audio element for an external file, loops it, and attempts playback.

- **Attack narrative:** When its browser checks match and the stored initiation date is more than three days old, the entrypoint disables page interaction and plays a looping audio file from flag-gimn.ru. This is targeted browser disruption within the published entrypoint.

- **Rationale:** The published browser entrypoint contains active, delayed disruption based on browser language and host suffix, followed by blocking page interaction and looping external audio. This supports a malicious protestware verdict and a publish block.

- **Files touched:** 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:** The package entrypoint is lib/RemoteCalibrator.min.js., The entrypoint checks for Russian-language browsers on hosts ending in .ru, .su, .by, or .xn--p1ai and waits until the stored initiation date is more than three days old., After the delay, the bundle disables page interaction and repeatedly plays an externally hosted audio file.

- **Evidence against:** The package has a prepare hook for Husky setup, but the identified attack behavior is in the browser entrypoint.

## Affected versions and remediation

This report applies to remote-calibrator@0.9.162.

- Avoid installing remote-calibrator@0.9.162. 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.
