The Android path serializes the IMAP configuration, potentially including its password, into that request. - **Trigger:** Import/use of the Android bootstrap or worker service with configured accounts. - **Impact:** Disclosure of email addresses, server metadata, and potentially IMAP passwords. - **Evidence paths:** android-bootstrap.ts, worker-entry.ts, sync-manager.ts, worker-bundle.js - **Review source:** ai\_review - **Reviewed:** 2026-07-22T12:45:00.592Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Unconsented remote diagnostic logging of account configuration. - **Attack narrative:** The Android bootstrap registers configured accounts and passes a log string containing JSON.stringify(account.imap) to vlog. vlog URL-encodes and sends it to rmf39.aaz.lt; IMAP configuration is normalized elsewhere with a password field. The worker path also transmits account email and host diagnostic data to that host during service operation. - **Rationale:** Source establishes a concrete runtime credential/configuration exfiltration path to an unrelated endpoint. No install hook is needed for this malicious behavior. - **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 vlog text to rmf39.aaz.lt., android-bootstrap.ts logs JSON.stringify(account.imap), which can include credentials., sync-manager.ts logs account email and IMAP host through the same vlog callback., worker-entry.ts independently sends runtime vlog data to rmf39.aaz.lt. - **Evidence against:** package.json has no npm lifecycle scripts., Other network calls target stated Google mail/Drive functionality. ## Public findings ### 1.
