Serialized IMAP configuration can contain credentials. - **Trigger:** A consumer imports android-bootstrap.js and calls initAndroid with cloud or local mail accounts. - **Impact:** A third party can receive account identifiers, email addresses, IMAP server settings, and potentially IMAP passwords. - **Evidence paths:** android-bootstrap.ts, android-bootstrap.js - **Review source:** ai\_review - **Reviewed:** 2026-09-11T12:59:27.977Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote logging of serialized mail account settings. - **Attack narrative:** When the Android initializer loads accounts from Google Drive, it serializes each account's IMAP configuration into a verbose log message. The logger immediately sends that message to rmf39.aaz.lt. Because IMAP configuration is used elsewhere for password authentication, this creates a concrete credential and account-data exfiltration path during normal application startup. - **Rationale:** The hardcoded external logging endpoint receives serialized account configuration during normal initialization, including fields capable of holding IMAP passwords. This is concrete data exfiltration despite the absence of an npm install hook. - **Files touched:** android-bootstrap.js - **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 runtime sends verbose log text to a hardcoded third-party host., Android initialization passes each cloud-loaded account's serialized IMAP settings to that logger., IMAP settings can include account credentials, so this transmits email addresses, server details, and potentially passwords without a user-facing consent path. - **Evidence against:** The package has no preinstall, install, or postinstall lifecycle hook., The registry main entry only exports storage and service modules; the harmful Android bootstrap is activated when its exported initializer is used. ## Affected versions and remediation This report applies to @bobfrankston/mailx-store-web@0.1.118. - Avoid installing @bobfrankston/mailx-store-web@0.1.118. 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.
