There is no user opt-in, and failures are swallowed. - **Trigger:** App import and runtime init of the Android bootstrap or worker service layer, including initAndroid and worker init. - **Impact:** IMAP passwords, mailbox emails, and account identifiers can be sent to rmf39.aaz.lt without the user agreeing to remote logging. - **Evidence paths:** worker-entry.ts, android-bootstrap.ts, main-thread-host.ts, web-settings.ts - **Review source:** ai\_review - **Reviewed:** 2026-09-17T19:10:55.072Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Always-on silent fetch of account and IMAP credential logs to a hardcoded remote logger - **Attack narrative:** When a consumer app starts the Android or worker mail service, vlog always POSTs truncated log lines to https://rmf39.aaz.lt/logit. Account registration includes the user email and JSON of the IMAP object, which carries the password field. That is unconsented credential and account-data leakage to a package-controlled host, not Google mail APIs. - **Rationale:** Source shows always-on silent fetches of account emails and JSON IMAP configs, including passwords, to rmf39.aaz.lt during normal runtime init. That is concrete credential exfiltration, not package-aligned Gmail or Drive traffic. - **Network endpoints:** https://rmf39.aaz.lt/logit/ ### Review decision - **Verdict:** Malicious - **Confidence:** 93.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** Always-on vlog in worker-entry.ts posts log text to https://rmf39.aaz.lt/logit with silent=true and errors swallowed., android-bootstrap.ts init sends JSON.stringify(account.imap) through that logger; that object includes the IMAP password., addAccount logs account email and IMAP auth details to the same host with no opt-in., Worker init injects that vlog into SyncManager, so account setup on worker start is sent outbound., main-thread-host.ts also posts vlog text to the same host., web-settings.ts normalizeAccount puts imap.password on the account object later stringified into vlog. - **Evidence against:** package.json has no preinstall, install, or postinstall hooks; main is a library export., Most of the package is a real Gmail, IMAP, and Drive mail store, not an obfuscated dropper., The outbound calls are plainly named verbose debug logging, not hidden behind encoding. ## Affected versions and remediation This report applies to @bobfrankston/mailx-store-web@0.1.120. - Avoid installing @bobfrankston/mailx-store-web@0.1.120. 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.
