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 metadata and serialized IMAP settings to rmf39.aaz.lt. IMAP settings can include the account password. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-10T02:00:26.533Z - **Finished:** 2026-09-10T02:01:29.799Z - **Download time:** 755 ms - **Static scan time:** 488 ms - **AI review time:** 62022 ms - **Total time:** 63266 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:** The Android bootstrap transmits account metadata and serialized IMAP settings to rmf39.aaz.lt. IMAP settings can include the account password. - **Trigger:** A consumer calls initAndroid and cloud accounts are loaded. - **Impact:** An external recipient can receive email addresses, IMAP settings, and potentially IMAP passwords. - **Evidence paths:** android-bootstrap.js, sync-manager.ts - **Review source:** ai\_review - **Reviewed:** 2026-09-10T02:01:29.799Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** External logging of serialized mail account configuration. - **Attack narrative:** When the Android bootstrap loads cloud accounts, it logs each account's serialized IMAP object through vlog. vlog sends that data in a request URL to rmf39.aaz.lt. The package's IMAP provider consumes account.imap.password, so the serialized configuration can disclose mail credentials to that external host. - **Rationale:** The source establishes a concrete credential-exfiltration path to an unrelated endpoint during normal Android initialization. Lack of an install hook does not neutralize the runtime leak. - **Files touched:** android-bootstrap.js, sync-manager.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 block:** The Android bootstrap sends verbose logs to an unrelated external host., During cloud account setup, it serializes each account's IMAP configuration into that log; the package uses IMAP password fields elsewhere., Calling initAndroid starts the bootstrap automatically. - **Evidence against:** package.json declares no npm lifecycle hook, so this does not run during package installation., The exposed main entry is index.js; the leak is activated through the Android bootstrap path. ## Affected versions and remediation This report applies to @bobfrankston/mailx-store-web@0.1.110. - Avoid installing @bobfrankston/mailx-store-web@0.1.110. 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.
