Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The browser entrypoint conditionally disrupts pages visited from Russian-language browsers on selected host suffixes. After a recorded first visit ages past three days, it blocks pointer interaction and repeatedly plays an externally hosted audio file. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-10-07T22:37:56.814Z - **Finished:** 2026-10-07T22:38:21.447Z - **Download time:** 2055 ms - **Static scan time:** 2645 ms - **AI review time:** 19931 ms - **Total time:** 24633 ms The recorded confidence comes from the underlying analysis.

After a recorded first visit ages past three days, it blocks pointer interaction and repeatedly plays an externally hosted audio file. - **Trigger:** Loading the package entrypoint in a browser with a Russian-language setting on a host ending in .ru, .su, .by, or .xn--p1ai, followed by a later visit more than three days after the timestamp was stored. - **Impact:** Users on affected pages can no longer interact through pointer events and are subjected to looping political audio. - **Evidence paths:** lib/RemoteCalibrator.min.js - **Review source:** ai\_review - **Reviewed:** 2026-10-07T22:38:21.447Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The code sets the page body's pointer events to none, adds a looping audio element sourced from flag-gimn.ru, and attempts playback after a short delay. - **Attack narrative:** When the browser language begins with Russian and the current host ends with a listed suffix, the bundle stores a timestamp in local storage. On a later visit after three days, it disables pointer interaction and attempts to play a looping audio file hosted at flag-gimn.ru. This is targeted browser disruption and protestware behavior. - **Rationale:** The package entrypoint contains a delayed, geographically and linguistically targeted browser disruption that plays looping political audio. This is concrete protestware behavior, so the package should be blocked. - **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's main entrypoint is the bundled JavaScript file containing the conditional browser behavior., On Russian-language browsers visiting selected host suffixes, the bundle records a first-visit timestamp and, after three days, disables page interaction and loops an external Ukraine-themed audio file., The package declares only a prepare hook that installs Husky; the harmful behavior is in its browser entrypoint, not an install hook. - **Evidence against:** The disruptive behavior is limited to Russian-language browsers on hosts ending in selected Russian or neighboring suffixes., The bundle also contains ordinary calibration and user interface functionality. ## Affected versions and remediation This report applies to remote-calibrator@0.9.156. - Avoid installing remote-calibrator@0.9.156. 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. ## Public findings ### 1.
