This configuration includes mail credentials. - **Trigger:** Calling initAndroid with a Gmail account and cloud-hosted accounts configured. - **Impact:** Exposes email addresses, mail server details, and IMAP passwords to the remote host. - **Evidence paths:** android-bootstrap.js, web-settings.js - **Review source:** ai\_review - **Reviewed:** 2026-09-11T10:51:12.888Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Serializes account IMAP settings into a remote logging URL. - **Attack narrative:** At runtime, the Android bootstrap loads accounts from Google Drive and logs each account's JSON-serialized IMAP configuration. The logging helper sends up to 800 characters of that message to rmf39.aaz.lt. The normalized account structure explicitly includes IMAP passwords, so configured credentials are transmitted to that unrelated endpoint. - **Rationale:** This is a concrete credential-exfiltration path: a password-bearing account object is serialized into a remote logging request. The lack of npm lifecycle hooks does not mitigate the runtime compromise. - **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:** Account normalization retains IMAP and SMTP passwords., The Android logger sends message text to rmf39.aaz.lt., During Google Drive account registration, the logger serializes the complete IMAP configuration, including its password field., Account registration logs the complete IMAP configuration by JSON-serializing account.imap. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., The exfiltration path is activated at Android runtime when Google Drive accounts are loaded, not during npm installation. ## Affected versions and remediation This report applies to @bobfrankston/mailx-store-web@0.1.116. - Avoid installing @bobfrankston/mailx-store-web@0.1.116. 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.
