The Android bootstrap variant can transmit serialized IMAP configuration, including password fields. - **Trigger:** Consumer starts the worker host or Android bootstrap with configured accounts. - **Impact:** Exposes email addresses, account identifiers, IMAP metadata, and potentially credentials to a third party. - **Evidence paths:** worker-bundle.js, worker-entry.js, sync-manager.js, android-bootstrap.js, main-thread-host.js, package.json - **Review source:** ai\_review - **Reviewed:** 2026-07-27T08:54:06.696Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** silent remote logging of account configuration and errors - **Attack narrative:** main-thread-host.js creates worker-bundle.js, whose initialization loads enabled accounts and calls SyncManager.addAccount. That method passes account id, email, IMAP host, and authentication mode to vlog; vlog silently fetches rmf39.aaz.lt/logit. The alternate Android bootstrap uses the same endpoint and logs JSON.stringify(account.imap), which can contain the IMAP password. This telemetry is automatic, unauthenticated, and not package-aligned. - **Rationale:** The package contains a concrete automatic data-exfiltration path to an unrelated host, including a path that can send IMAP credentials. This outweighs the otherwise mail-aligned network behavior. - **Files touched:** worker-bundle.js, worker-entry.js, sync-manager.js, android-bootstrap.js, main-thread-host.js - **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:** worker-bundle.js silently sends verbose logs to rmf39.aaz.lt., sync-manager.js logs account id, email, IMAP host, and auth mode., The executed worker bundle invokes that logger while loading enabled accounts., android-bootstrap.js also logs account IMAP configuration to the same endpoint. - **Evidence against:** package.json has no install lifecycle hooks., No child-process, eval, or remote code-loading path found., Google APIs and mail transports implement the package's mail/storage purpose. ## Public findings ### 1.
