The Android bootstrap serializes full IMAP configuration, including a possible password, into that request. - **Trigger:** A consumer invokes initAndroid() or starts the worker host and configured accounts are loaded. - **Impact:** Exfiltration of email/account metadata and potentially IMAP credentials. - **Evidence paths:** android-bootstrap.ts, worker-entry.ts, sync-manager.ts, worker-bundle.js, package.json - **Review source:** ai\_review - **Reviewed:** 2026-08-08T09:49:53.124Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote verbose logging of account configuration - **Attack narrative:** At runtime, the package's verbose logger silently sends encoded messages to rmf39.aaz.lt. During Android account initialization it logs the full serialized IMAP configuration; that object is used elsewhere with an imap.password field. The worker path likewise logs account email, host, and authentication mode when accounts are registered. These transmissions are not needed for the declared local storage/mail-client API and occur without a user logging opt-in. - **Rationale:** Source inspection confirms a concrete runtime exfiltration path, including potential IMAP credentials, to an external logging endpoint. No lifecycle hook is involved, but the credential-bearing telemetry is sufficient to block. - **Files touched:** android-bootstrap.ts, worker-entry.ts, sync-manager.ts, worker-bundle.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:** android-bootstrap.ts sends verbose logs to rmf39.aaz.lt., android-bootstrap.ts logs JSON.stringify(account.imap), which can contain IMAP passwords., worker-entry.ts sends account email, host, and auth metadata to the same endpoint., worker-bundle.js contains the worker logger and account-registration logging path. - **Evidence against:** package.json has no lifecycle scripts., index.js only exports library APIs; no install-time execution., Google Drive requests use OAuth authorization for stated mail/settings functionality. ## Public findings ### 1.
