Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Normal Android initialization uploads serialized IMAP account configuration to rmf39.aaz.lt. This can disclose account identifiers, email addresses, server details, and credentials embedded in the IMAP configuration. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-14T00:36:53.969Z - **Finished:** 2026-09-14T00:37:38.680Z - **Download time:** 756 ms - **Static scan time:** 261 ms - **AI review time:** 43693 ms - **Total time:** 44711 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** Normal Android initialization uploads serialized IMAP account configuration to rmf39.aaz.lt. This can disclose account identifiers, email addresses, server details, and credentials embedded in the IMAP configuration. - **Trigger:** Calling initAndroid and loading accounts from Google Drive during app startup. - **Impact:** Mailbox credentials and account metadata may be exposed to an unrelated external host. - **Evidence paths:** android-bootstrap.js - **Review source:** ai\_review - **Reviewed:** 2026-09-14T00:37:38.680Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote logging of serialized IMAP configuration. - **Attack narrative:** The Android bootstrap defines a logger that sends message text to rmf39.aaz.lt. During normal cloud-account reconciliation, it passes a string containing each account email and JSON-serialized IMAP configuration to that logger. Because IMAP configuration may include credentials, ordinary startup can transmit sensitive mailbox data to the external logging host without a user action directed at that host. - **Rationale:** The source directly connects account configuration serialization to an external logging request. Absence of an npm lifecycle hook does not mitigate this runtime credential-exfiltration path. - **Files touched:** android-bootstrap.js - **Network endpoints:** rmf39.aaz.lt ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** Android runtime sends every vlog message to a non-service logging host., Startup serializes each cloud-loaded account's IMAP configuration into that remote log message., IMAP configuration can contain mailbox credentials, so this creates credential exfiltration during normal app startup. - **Evidence against:** package.json has no install lifecycle hook., The package's main entry only re-exports modules; the harmful path is Android runtime initialization. ## Affected versions and remediation This report applies to @bobfrankston/mailx-store-web@0.1.119. - Avoid installing @bobfrankston/mailx-store-web@0.1.119. 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.
