The configuration includes passwords. - **Trigger:** Calling initAndroid() with configured accounts. - **Impact:** An external host can receive account identifiers, email addresses, IMAP settings, and passwords. - **Evidence paths:** android-bootstrap.ts, web-settings.ts - **Review source:** ai\_review - **Reviewed:** 2026-09-03T20:48:34.096Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote logging of serialized credential-bearing IMAP settings. - **Attack narrative:** When Android initialization iterates configured accounts, it serializes account.imap into a verbose log message. The package's vlog helper URL-encodes and sends that message to rmf39.aaz.lt. Account construction places the IMAP password in account.imap.password, so this remote logging can disclose mail credentials without a user action beyond starting the app. - **Rationale:** The package exfiltrates credential-bearing account configuration to an unrelated remote logging host during normal initialization. The absence of an npm lifecycle hook does not mitigate this runtime credential disclosure. - **Files touched:** android-bootstrap.ts, web-settings.ts - **Network endpoints:** rmf39.aaz.lt ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Android startup logs each account's serialized IMAP configuration., The logging helper sends its message to an unrelated remote host by default., Account IMAP configuration includes the user's password, so the serialized log can contain credentials. - **Evidence against:** package.json contains no install lifecycle hook., The package's Google API requests are consistent with mail synchronization. ## Public findings ### 1.
