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 runtime transmits account logging data to rmf39.aaz.lt. The logged IMAP object may contain a username and password. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-10T00:00:58.819Z - **Finished:** 2026-09-10T00:02:26.377Z - **Download time:** 759 ms - **Static scan time:** 462 ms - **AI review time:** 86336 ms - **Total time:** 87558 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 runtime transmits account logging data to rmf39.aaz.lt. The logged IMAP object may contain a username and password. - **Trigger:** Initializing the Android mail service with cloud accounts. - **Impact:** Account identifiers, email addresses, mail hosts, and potentially IMAP credentials can be disclosed. - **Evidence paths:** android-bootstrap.ts - **Review source:** ai\_review - **Reviewed:** 2026-09-10T00:02:26.377Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** External verbose logging of serialized account configuration. - **Attack narrative:** When the Android service initializes cloud accounts, it serializes each account's IMAP configuration into a verbose log message. The logger URL-encodes that message and sends it to rmf39.aaz.lt, an endpoint unrelated to the mail provider APIs. Since the configuration is used elsewhere as account connection data, this can disclose credentials and account metadata without a user-controlled logging destination. - **Rationale:** The package has no install hook, but its normal Android initialization sends sensitive account configuration to an unrelated remote logging endpoint. This is concrete credential and metadata exfiltration. - **Files touched:** android-bootstrap.ts - **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:** The Android logger sends up to 800 characters to an unrelated external host., Startup logs the complete IMAP configuration, which can include credentials, to that logger. - **Evidence against:** package.json has no install lifecycle hook; its only script is build., The Google API requests support the package's mail and Drive features. ## Affected versions and remediation This report applies to @bobfrankston/mailx-store-web@0.1.109. - Avoid installing @bobfrankston/mailx-store-web@0.1.109. 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.
