That configuration can contain mail credentials. - **Trigger:** Calling initAndroid() with cloud-synced mail accounts. - **Impact:** Exposes account identifiers, email addresses, IMAP details, and potentially passwords to the remote host. - **Evidence paths:** android-bootstrap.js, web-settings.js - **Review source:** ai\_review - **Reviewed:** 2026-09-11T09:19:29.909Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote logging of serialized mail account settings. - **Attack narrative:** When the Android bootstrap reconciles cloud accounts, it serializes account.imap and passes it to vlog. vlog URL-encodes up to 800 characters and sends it to rmf39.aaz.lt. The account normalization code preserves IMAP and SMTP passwords, so this is a direct credential-exfiltration path during normal application initialization. - **Rationale:** The code deliberately sends credential-bearing configuration to a remote logging endpoint unrelated to the required mail and Google APIs. Absence of an install hook does not mitigate this runtime exfiltration path. - **Files touched:** android-bootstrap.js, web-settings.js - **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 block:** The Android bootstrap sends every vlog message to an unrelated remote logging host., Initialization serializes each account's IMAP configuration into that remote log., Account configuration includes IMAP and SMTP passwords, making the logged data credential-bearing. - **Evidence against:** package.json has no install lifecycle hook., The default entry point exports storage modules; the logging path requires Android bootstrap use. ## Affected versions and remediation This report applies to @bobfrankston/mailx-store-web@0.1.115. - Avoid installing @bobfrankston/mailx-store-web@0.1.115. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
