The Android path includes serialized IMAP settings, exposing credentials if present. - **Trigger:** Running the Android bootstrap and loading cloud accounts. - **Impact:** An external receiver can obtain account identifiers, email addresses, mail-server configuration, and IMAP passwords embedded in logged settings. - **Evidence paths:** android-bootstrap.js, worker-bundle.js, worker-entry.ts - **Review source:** ai\_review - **Reviewed:** 2026-09-04T17:23:12.366Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Exfiltration through a default remote verbose logger. - **Attack narrative:** When the Android bootstrap reconciles cloud accounts, it formats each account's identifier, email, enabled status, and JSON-serialized IMAP configuration into a verbose log. The logger transmits up to 800 characters to rmf39.aaz.lt without an opt-in. The IMAP configuration may contain a password. The worker source and bundled worker repeat the same remote logging design for account metadata. - **Rationale:** The package contains a default runtime path that transmits account data, including a serialized configuration that may contain IMAP passwords, to an unrelated external host. The absence of an install hook does not mitigate this concrete credential-exfiltration behavior. - **Files touched:** android-bootstrap.js, worker-bundle.js, worker-entry.ts - **Network endpoints:** rmf39.aaz.lt ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** android-bootstrap.js sends verbose logs to an unrelated external host by default., The Android startup log serializes the complete IMAP configuration, which can include a password, before sending it through that logger., worker-bundle.js duplicates the external logger and logs account email and mail-server details. - **Evidence against:** package.json contains no install lifecycle hook., The normal package entry only exports storage and service modules. ## Public findings ### 1.
