One logged value serializes the complete IMAP account object, including any configured password. - **Trigger:** Calling the exported Android initialization path with configured mail accounts. - **Impact:** An operator of the logging host can receive email addresses, server details, and IMAP credentials. - **Evidence paths:** android-bootstrap.js, package.json, index.js, sync-manager.js, worker-entry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-29T22:09:28.732Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote logging of mail account configuration. - **Attack narrative:** When Android initialization registers cloud-backed accounts, it formats the complete IMAP configuration as a verbose log message. The logging helper sends up to 800 characters of that message to rmf39.aaz.lt. Because the IMAP configuration is also used as the source of the password passed to the mail provider, this creates a concrete credential-exfiltration path to an unrelated host. - **Rationale:** The package contains a direct runtime path that serializes sensitive IMAP configuration and sends it to an unrelated remote logging endpoint. This is concrete credential exfiltration, despite the absence of an install hook. - **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:** The Android bootstrap sends verbose logs to an unrelated remote host., Account setup logs include the whole IMAP configuration, which can contain the password., The same remote logging runs during account registration and periodic mailbox activity. - **Evidence against:** The manifest has no install lifecycle hook or self-dependency., The normal package entry point only exports web mail storage APIs. ## Public findings ### 1.

High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 99.0% - **Path:** android-bootstrap.js - **Public source:** [View source]() The same remote logging runs during account registration and periodic mailbox activity. Public source snippet (untrusted): ```javascript async addAccount(account) { vlog(`addAccount id=${account.id} email=${account.email} host=${account.imap?.host} auth=${account.imap?.auth}`); this.db.upsertAccount(account.id, account.name, account.email, JSON.stringify(account)); ``` ## Dependencies and install lifecycle - **Lifecycle scripts present:** No - **Dependencies:** 7 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 7 ### Published dependency entries - @bobfrankston/iflow-direct ^0.1.68 (Dependency) - @bobfrankston/mailx-bus ^0.1.2 (Dependency) - @bobfrankston/mailx-sync ^0.1.29 (Dependency) - @bobfrankston/mailx-types ^0.1.76 (Dependency) - @bobfrankston/smtp-direct ^0.1.9 (Dependency) - @bobfrankston/tcp-transport ^0.1.8 (Dependency) - sql.js ^1.14.1 (Dependency) ## Package metadata - **Package:** @bobfrankston/mailx-store-web - **Ecosystem:** npm - **Version:** 0.1.99 - **License:** ISC - **Version published:** 2026-08-29T15:03:40.580Z - **Package first seen:** 2026-07-02T13:06:13.825Z - **Package last seen:** 2026-08-29T22:09:28.732Z - **Known versions:** 40 - **Latest version:** 0.1.99 - **Appeal under review:** No - **Artifact files:** 76 - **Artifact unpacked size:** 1,130,553 bytes - **Artifact signatures:** 1 - **Attestations:** No ## References - [HTML security report]() - [Repository]() - [Homepage]() - [Issues]()
