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. When the Android bootstrap is initialized with mail accounts, it transmits account diagnostics to a hard-coded third-party logging host. The transmitted IMAP configuration can include the account password. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-11T01:35:29.666Z - **Finished:** 2026-09-11T01:36:24.569Z - **Download time:** 763 ms - **Static scan time:** 455 ms - **AI review time:** 53685 ms - **Total time:** 54903 ms The recorded confidence comes from the underlying analysis.

The transmitted IMAP configuration can include the account password. - **Trigger:** A consumer imports and calls initAndroid, then loads cloud-backed accounts. - **Impact:** An external host can receive email addresses, mail-server details, and IMAP passwords. - **Evidence paths:** android-bootstrap.js - **Review source:** ai\_review - **Reviewed:** 2026-09-11T01:36:24.569Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Hard-coded remote logging of serialized mail-account configuration. - **Attack narrative:** The exported Android bootstrap loads account records and sends a JSON serialization of each IMAP configuration to the hard-coded rmf39.aaz.lt logging endpoint. The same configuration is used with account.imap.password for IMAP authentication, so the serialized diagnostic can disclose mail credentials to that unrelated receiver. - **Rationale:** The package contains a concrete runtime credential-exfiltration path to a hard-coded third-party host. The absence of an install hook does not mitigate this behavior when the Android bootstrap runs. - **Files touched:** android-bootstrap.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 diagnostic text to a hard-coded third-party host., Startup logging serializes each account's IMAP configuration before sending it; that configuration contains the IMAP password., Account email addresses and IMAP hosts are also sent through the same logging path. - **Evidence against:** package.json has no install lifecycle hook., The main entry exports storage APIs and does not import the Android bootstrap. ## Affected versions and remediation This report applies to @bobfrankston/mailx-store-web@0.1.112. - Avoid installing @bobfrankston/mailx-store-web@0.1.112. 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.
