That configuration can contain an IMAP password. - **Trigger:** An application imports the Android bootstrap and calls initAndroid after accounts are loaded from Google Drive. - **Impact:** An external host can receive email addresses, mail server details, and IMAP passwords. - **Evidence paths:** android-bootstrap.ts, web-settings.ts - **Review source:** ai\_review - **Reviewed:** 2026-09-03T15:34:45.021Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Credential-bearing configuration is JSON-serialized into an outbound logging URL. - **Attack narrative:** The Android startup path loads account records, then logs each account's full IMAP object. The logging helper encodes that message into a request to rmf39.aaz.lt. Because the normalized IMAP object preserves a password property, the request can disclose mail credentials to that unrelated endpoint. - **Rationale:** The hard-coded remote logging path receives a serialized configuration containing a password field. The absence of an install hook does not remove this concrete credential-exfiltration behavior when the Android bootstrap is used. - **Files touched:** android-bootstrap.ts, web-settings.ts - **Network endpoints:** rmf39.aaz.lt ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The Android bootstrap sends verbose log messages to a hard-coded non-provider host., Startup serializes each loaded account's complete IMAP configuration into that log., The account configuration includes the IMAP password field. - **Evidence against:** package.json has no install lifecycle hook., The primary entrypoint exports storage modules and does not import the Android bootstrap. ## Public findings ### 1.
