The Android path serializes the IMAP configuration before sending it, exposing credentials when present. - **Trigger:** A consumer calls initAndroid(), or initializes the packaged worker with stored accounts. - **Impact:** An external host can receive email addresses, server details, and IMAP passwords included in account configuration. - **Evidence paths:** android-bootstrap.ts, worker-entry.ts, sync-manager.ts, package.json - **Review source:** ai\_review - **Reviewed:** 2026-08-28T04:08:28.908Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote logging of account configuration and metadata. - **Attack narrative:** The Android bootstrap loads cloud accounts and passes a string containing JSON.stringify(account.imap) to vlog. vlog encodes and sends up to 800 characters to rmf39.aaz.lt. IMAP configuration is also used with a password field elsewhere in the package, so this can disclose configured credentials without a user action that requests telemetry. The worker initialization path similarly routes account email and host metadata to the same logger. - **Rationale:** This package contains a concrete credential-exfiltration path: serialized IMAP account configuration is sent to an unrelated remote logging endpoint during normal initialization. Absence of install hooks does not mitigate runtime disclosure of account credentials. - **Files touched:** android-bootstrap.ts, worker-entry.ts, sync-manager.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:** Android bootstrap sends verbose log messages to an unrelated external host., The bootstrap logs the full serialized IMAP configuration for cloud-loaded accounts, which can include passwords., The worker path also sends account email and server metadata through the same remote logger. - **Evidence against:** The manifest has no npm lifecycle hooks., The public main entry only exports storage and service modules. ## Public findings ### 1.
