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. When the mail client initializes, account records are copied into a URL and sent to rmf39.aaz.lt. The Android init path stringifies the IMAP object, which is built with a password field. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-09-22T19:03:54.099Z - **Finished:** 2026-09-22T19:05:49.979Z - **Download time:** 771 ms - **Static scan time:** 263 ms - **AI review time:** 114844 ms - **Total time:** 115880 ms The recorded confidence comes from the underlying analysis.

The Android init path stringifies the IMAP object, which is built with a password field. - **Trigger:** Calling initAndroid or the worker init path that registers accounts. - **Impact:** Mailbox email addresses and IMAP settings, including a stored password when present, are disclosed to that host. - **Evidence paths:** android-bootstrap.ts, web-settings.ts, worker-entry.ts, worker-bundle.js, main-thread-host.ts, sync-manager.ts - **Review source:** ai\_review - **Reviewed:** 2026-09-22T19:05:49.979Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** vlog encodes up to 800 characters of the log line into the path of a GET request to https://rmf39.aaz.lt/logit/ and discards errors. - **Attack narrative:** Starting the packaged mail client calls initAndroid or the worker initializer. Registration builds a log line with the account email and JSON.stringify of the IMAP config, whose normalized shape includes password. vlog places that text in a GET to https://rmf39.aaz.lt/logit/ with silent=true and an empty catch. The same host is wired in the worker bundle and the main-thread vlog bridge. No install hook is required; the send happens on normal startup. - **Rationale:** Account startup silently uploads IMAP configuration, including the password field, to the hardcoded host rmf39.aaz.lt. That is a default credential export to a package-controlled recipient outside the mail provider. - **Network endpoints:** https://rmf39.aaz.lt/logit/ ### Review decision - **Verdict:** Malicious - **Confidence:** 88.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** initAndroid logs the full IMAP account object with JSON.stringify, and that object includes the password field., vlog sends the text in a GET path to https://rmf39.aaz.lt/logit/ and ignores failures., The same hardcoded logit host is in worker-entry.ts, worker-bundle.js, and main-thread-host.ts., Account registration also sends email address, IMAP host, and auth type through vlog., There is no opt-in gate; initialization always performs the request. - **Evidence against:** package.json has only a build script and no preinstall, install, or postinstall hook., Google Drive and Gmail calls use the user bearer token against googleapis.com., Source comments describe the request as verbose logit for the mail app. ## Affected versions and remediation This report applies to @bobfrankston/mailx-store-web@0.1.122. - Avoid installing @bobfrankston/mailx-store-web@0.1.122. 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.
