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. Android startup forwards serialized mail account configuration, including authentication fields, to a fixed external logging receiver. Disabled accounts are logged too. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-10-02T09:22:03.301Z - **Finished:** 2026-10-02T09:23:32.736Z - **Download time:** 1020 ms - **Static scan time:** 292 ms - **AI review time:** 88123 ms - **Total time:** 89435 ms The recorded confidence comes from the underlying analysis.

Disabled accounts are logged too. - **Trigger:** Calling initAndroid and successfully loading cloud accounts. - **Impact:** Mail usernames and passwords can reach a receiver unrelated to their authenticated mail servers, subject to the message length limit. - **Evidence paths:** android-bootstrap.js - **Review source:** ai\_review - **Reviewed:** 2026-10-02T09:23:32.736Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The account-loading loop serializes account.imap into a log message; vlog URL-encodes its first 800 characters and sends them through fetch to rmf39.aaz.lt. - **Attack narrative:** The Android bootstrap retrieves cloud account records and logs each account's complete IMAP configuration before checking its enabled status. That configuration supplies the password used for IMAP authentication. The logging helper automatically sends the message to a hardcoded external receiver, truncating it to 800 characters and suppressing request failures. No separate consent gate protects this credential transfer. - **Rationale:** Source inspection establishes automatic forwarding of mail authentication configuration to a fixed external receiver during Android initialization. This concrete credential exposure supports blocking independently of scanner similarity claims. - **Network endpoints:** https://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 initialization loads account records from Google Drive., The account-loading loop logs the complete IMAP configuration before checking whether the account is enabled., The logging function sends up to 800 characters to the fixed external host rmf39.aaz.lt without a consent gate., The serialized IMAP configuration contains the username and password used for mail authentication., The exported Android initialization path activates this account-loading behavior. - **Evidence against:** package.json has no installation lifecycle hooks., The inspected worker source logs account metadata; the concrete credential exposure occurs in android-bootstrap.js. ## Affected versions and remediation This report applies to @bobfrankston/mailx-store-web@0.1.126. - Avoid installing @bobfrankston/mailx-store-web@0.1.126. 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.
