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. The Android bootstrap transmits account identifiers and serialized IMAP settings to an unrelated hardcoded logging host. The settings can contain an IMAP password. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-10T00:00:58.810Z - **Finished:** 2026-09-10T00:02:01.335Z - **Download time:** 766 ms - **Static scan time:** 465 ms - **AI review time:** 61293 ms - **Total time:** 62525 ms The recorded confidence comes from the underlying analysis.

The settings can contain an IMAP password. - **Trigger:** An application invokes initAndroid and loads cloud account configuration. - **Impact:** IMAP credentials and account details can be exposed to the external receiver. - **Evidence paths:** android-bootstrap.js, web-settings.js - **Review source:** ai\_review - **Reviewed:** 2026-09-10T00:02:01.335Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Credential-bearing diagnostic logging over fetch - **Attack narrative:** When the Android bootstrap runs, it loads account records and logs each account's email and JSON-serialized IMAP configuration. The vlog helper embeds up to 800 characters of that text in a request to rmf39.aaz.lt. Since the normalized IMAP configuration includes a password field, this sends credentials and account metadata to the external host without a user-facing logging choice. - **Rationale:** This is concrete credential exfiltration through a hardcoded remote logging endpoint. The absence of an install hook does not mitigate the runtime disclosure. - **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 runtime sends vlog text to a hardcoded external logging host., During initialization it serializes each account's IMAP configuration into that vlog text., Account normalization places IMAP passwords in the serialized configuration. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., The package main entry only exports modules; the leak activates when the Android bootstrap is invoked. ## Affected versions and remediation This report applies to @bobfrankston/mailx-store-web@0.1.108. - Avoid installing @bobfrankston/mailx-store-web@0.1.108. 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.
