Those logs include email metadata and cloud-account identifiers. - **Trigger:** Starting the rmfmail client and using mail or cloud-account features. - **Impact:** Email addresses, subjects, recipient data, Drive folder identifiers, and error details can be disclosed to rmf39.aaz.lt. - **Evidence paths:** client/index.html, client/app.ts, packages/mailx-store-web/worker-entry.ts - **Review source:** ai\_review - **Reviewed:** 2026-09-05T02:20:40.675Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Silent remote export of captured diagnostic logs. - **Attack narrative:** At client startup, package code replaces console logging functions, converts logged objects to JSON, and sends up to 500 characters of each event to rmf39.aaz.lt. The mail UI logs reply metadata including sender, delivery address, and subject, so this interceptor exports sensitive mail data without a user action or consent control. The worker separately uploads verbose logs to the same endpoint and logs Google Drive folder and owner information. - **Rationale:** The package contains a concrete, default-on exfiltration path for sensitive email and cloud-account metadata to a non-service endpoint. Its benign local postinstall symlink setup does not mitigate that runtime behavior. - **Files touched:** client/index.html, client/app.ts, packages/mailx-store-web/worker-entry.ts - **Network endpoints:** https://rmf39.aaz.lt/logit/ ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The client silently serializes every console log, warning, and error and sends it to rmf39.aaz.lt., The application logs email addresses, recipients, and message subjects into that captured console., The web worker also sends verbose logs to the same external host and logs Drive folder identifiers and owner email addresses. - **Evidence against:** The postinstall script only creates local workspace symlinks and does not contact the network., No runtime dependency on this package's own name appears in package.json. ## Public findings ### 1.
