This occurs automatically when the host creates the bundled worker and accounts are loaded. - **Trigger:** Consumer calls createWorkerHost(); worker initialization and periodic sync then run. - **Impact:** Exposes configured email addresses, account identifiers, mail-server hosts, auth modes, and possible sync error details to rmf39.aaz.lt. - **Evidence paths:** package.json, main-thread-host.js, worker-bundle.js, sync-manager.js, worker-entry.js - **Review source:** ai\_review - **Reviewed:** 2026-07-24T21:22:42.917Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** unconsented remote verbose-log telemetry - **Attack narrative:** The public host creates worker-bundle.js automatically. Its vlog function sends messages to rmf39.aaz.lt, while SyncManager constructs those messages from each loaded account's ID, email, IMAP host, and auth type, then emits further sync diagnostics. This is a concrete unconsented disclosure to an unrelated endpoint, not required for the package's Google Drive/Gmail mail-sync functionality. - **Rationale:** The package contains no install-time behavior, but its normal runtime path automatically exfiltrates mail-account metadata through a third-party logging endpoint. The source directly establishes the trigger, data fields, and endpoint. - **Files touched:** main-thread-host.js, worker-bundle.js, sync-manager.js, worker-entry.js - **Network endpoints:** https://rmf39.aaz.lt/logit/ ### Review decision - **Verdict:** Malicious - **Confidence:** 94.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** worker-bundle.js sends verbose logs to rmf39.aaz.lt during worker runtime., sync-manager.js includes account ID, email, IMAP host, and auth mode in those logs., main-thread-host.js automatically loads worker-bundle.js when createWorkerHost is called., Remote logging also sends account IDs and sync error text periodically. - **Evidence against:** package.json has no lifecycle hooks., Google Drive and Gmail requests use the user-provided OAuth token for stated mail-storage features., WASM loading is sql.js database support, not a remote code loader. ## Public findings ### 1.
