Those settings can include the user's email address, IMAP username, host, and password. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-28T04:48:04.093Z - **Finished:** 2026-08-28T04:48:59.316Z - **Download time:** 755 ms - **Static scan time:** 912 ms - **AI review time:** 53555 ms - **Total time:** 55223 ms ## Security analysis ### Published attack-surface review - **Summary:** At Android runtime, account setup transmits serialized IMAP settings to a remote logging host. Those settings can include the user's email address, IMAP username, host, and password. - **Trigger:** Initializing the Android/WebView mail service with Google Drive accounts. - **Impact:** IMAP credentials and account metadata may be exfiltrated to rmf39.aaz.lt. - **Evidence paths:** android-bootstrap.ts, web-settings.ts, package.json - **Review source:** ai\_review - **Reviewed:** 2026-08-28T04:48:59.316Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote verbose logging of serialized account configuration. - **Attack narrative:** The package initializes mail accounts from Google Drive, serializes each account's IMAP configuration into a verbose log message, and sends that message to rmf39.aaz.lt. Its configuration builder includes the IMAP password in that serialized object. This creates a direct runtime credential-exfiltration path without an install hook. - **Rationale:** Source establishes a direct path from account credentials to a third-party logging endpoint during ordinary initialization. This is concrete credential exfiltration, not required mail-storage functionality. - **Files touched:** android-bootstrap.ts, web-settings.ts - **Network endpoints:** https://rmf39.aaz.lt/logit/ ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The Android runtime sends verbose logs to an unrelated remote host., During Google Drive account setup, it logs the full serialized IMAP configuration., The normalized IMAP configuration includes a password field, so that serialized log can contain credentials. - **Evidence against:** package.json has no install or lifecycle hooks., Google Drive requests use an OAuth bearer token for the package's stated settings-sync function. ## Public findings ### 1.
