Full IMAP configuration is sent during cloud-account setup and may contain a password. - **Trigger:** Consumer invokes initAndroid() or initializes the worker with mail accounts. - **Impact:** Exposure of email addresses, account identifiers, mail-server details, errors, and potentially IMAP passwords. - **Evidence paths:** android-bootstrap.ts, worker-entry.ts, sync-manager.ts, package.json - **Review source:** ai\_review - **Reviewed:** 2026-08-12T00:14:55.548Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote logging of account configuration and runtime diagnostics. - **Attack narrative:** When the Android mail runtime initializes accounts, it passes account fields and a JSON serialization of each IMAP configuration to vlog. vlog encodes the message into a request to rmf39.aaz.lt; the same runtime uses the IMAP password from that configuration. This creates a concrete, recurring credential and account-metadata exfiltration path without an install hook. - **Rationale:** Source establishes a direct remote logging sink and sensitive account/configuration inputs reaching it. The absence of lifecycle hooks does not mitigate the runtime exfiltration behavior. - **Files touched:** android-bootstrap.ts, worker-entry.ts, sync-manager.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:** Runtime logger sends encoded messages to rmf39.aaz.lt., Account registration logs account ID, email, IMAP host, and auth type., Cloud-account initialization serializes the full IMAP configuration into that logger; the same config supplies the IMAP password., The logger is invoked during initialization and recurring sync activity. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., Main entry only exports library modules; the behavior activates in the Android/worker runtime path. ## Public findings ### 1.
