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 can disable page interaction and play looping audio after a stored three-day delay. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-10-07T22:38:17.911Z - **Finished:** 2026-10-07T22:38:40.792Z - **Download time:** 1548 ms - **Static scan time:** 2889 ms - **AI review time:** 18443 ms - **Total time:** 22881 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** The browser entrypoint can disable page interaction and play looping audio after a stored three-day delay. - **Trigger:** The bundle runs in a browser where the language and hostname checks match and the stored delay has elapsed. - **Impact:** Affected visitors may be unable to interact with the page and may hear repeated audio. - **Evidence paths:** lib/RemoteCalibrator.min.js - **Review source:** ai\_review - **Reviewed:** 2026-10-07T22:38:40.792Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** It sets the page body to ignore pointer events, appends looping audio from a fixed external URL, and attempts playback. - **Attack narrative:** The runtime browser bundle checks the visitor language and hostname, records an initial timestamp, and after more than three days disables page interaction and attempts to play looping audio from a fixed external host. This is targeted browser disruption unrelated to the package’s calibration purpose. - **Rationale:** The main runtime bundle contains targeted browser disruption with a concrete user impact. The conditional trigger does not make the behavior benign. - **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 manifest sets the browser bundle as its main entrypoint., The bundle contains a delayed browser disruption that disables page interaction and loads looping audio from a fixed external host. - **Evidence against:** The prepare hook only runs Husky setup; the disruption is in the runtime browser entrypoint. ## Affected versions and remediation This report applies to remote-calibrator@0.9.163. - Avoid installing remote-calibrator@0.9.163. 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.
